The Performance Comparison between the Intel Core i7-7700K and i7-7740X on the X299 Platform

In this review, we put the Intel Core i7-7700K and i7-7740X through their paces to see how they perform in various benchmarks. We started by looking at the stock settings for each CPU, comparing their average frame rates across different games. The 7700K was found to have an average of 44.3 FPS, with lows of 36.4 and 1% lows of 33.2. In contrast, the 7740X had an average of 44.8 FPS, with lows of 108 FPS and 1% lows of 33.2. This may seem like a significant difference, but it's worth noting that these results are averages over multiple tests, and there was very little variation.

One potential factor that could be contributing to the difference in performance is the fact that both CPUs were running on different motherboards. The 7700K was found to be slightly better in some games, such as Grand Theft Auto V, while the 7740X had a slight edge in others. However, when we looked at synthetic benchmarks like Ashes, the results were largely identical.

The Intel Core i7-7740X is not a significantly different CPU from the 7700K, and it's hard to see why anyone would choose one over the other for gaming purposes. Both CPUs are essentially the same, with the only real difference being the inclusion of an integrated GPU (iGPU) on the 7740X. However, as we mentioned earlier, this difference is relatively minor, and the 7700K's performance in games is largely unaffected by the presence or absence of an iGPU.

In terms of power consumption, the 7740X has a slightly higher TDP rating than the 7700K, but it's worth noting that this may not necessarily translate to real-world differences in performance. The base clock speed on the 7740X is also 100 MHz faster than the 7700K, but as we mentioned earlier, this difference is unlikely to have a significant impact on gaming performance.

Ultimately, if you're looking for a gaming-focused CPU from Intel, it's hard to recommend the i7-7740X over the 7700K. Both CPUs are essentially identical, and the only real differences are relatively minor and not particularly relevant to most gamers. However, if you do decide to go with the X299 platform, there are some great motherboards available that can help to unlock the full potential of your CPU.

One area where the 7740X does have an advantage is in the realm of content creation and professional use cases. While the 7700K is more than capable of handling most tasks, the 7740X has a few features that make it more appealing to professionals and power users. These include improved multithreading performance and increased RAM support.

In our previous review of the X299 platform, we noted that there were still some limitations to its capabilities compared to other platforms like Z270. However, with the introduction of new motherboards and drivers, these issues have largely been addressed. Today's CPUs are more refined, more powerful, and more user-friendly than ever before.

In conclusion, if you're looking for a gaming-focused CPU from Intel, it's hard to recommend the i7-7740X over the 7700K. Both CPUs are essentially identical, but with the added feature of an integrated GPU on the 7740X. However, if you do decide to go with the X299 platform, there are some great motherboards available that can help to unlock its full potential.

Ultimately, our recommendation is to look for a good motherboard and a decent CPU, rather than trying to find a specific model like the i7-7740X or 7700K. The X299 platform has a lot to offer, and with the right components, it's possible to build a powerful and efficient system that can handle even the most demanding tasks.

We also want to note that while the CPUs themselves are similar, the motherboard is a different story. The x299 chipset is not as mature as z270, and there are still some issues with driver support and compatibility. However, with the introduction of new motherboards and drivers, these issues have largely been addressed. Today's X299 platform is more refined, more powerful, and more user-friendly than ever before.

In our final conclusion, we want to emphasize that if you're looking for a gaming-focused CPU from Intel, it's hard to recommend the i7-7740X over the 7700K. Both CPUs are essentially identical, but with the added feature of an integrated GPU on the 7740X. However, if you do decide to go with the X299 platform, there are some great motherboards available that can help to unlock its full potential.

We also want to note that our final recommendation is to look for a good motherboard and a decent CPU, rather than trying to find a specific model like the i7-7740X or 7700K. The X299 platform has a lot to offer, and with the right components, it's possible to build a powerful and efficient system that can handle even the most demanding tasks.

"WEBVTTKind: captionsLanguage: enwhy does kbl Lake X exist that's the question we asked Intel at their press day it's not compatible with LGA 1151 it works with more expensive motherboards and half of the components on the board will go unused for example four of these dims you can't use with kbl Lake X and then part of the pcie devices as well if you're planning to populate them so those features aren't free to the consumer you pay for all the stuff on the board but the CPU can't drive them so it ends up in a very weird part of the market we asked Intel about why this product exists and why it's 2066 and not 1151 we'll have an answer for you in a moment but if you look under the die even the top part of the substrate looks pretty familiar so we're not fully convinced that this product needs to exist in the package it does but we're going to be here reviewing It Anyway looking through thermals gaming performance and more before getting to that this video is brought to you by ifixit.com and the piec Essentials toolkit which can be had for $20 making it one of their cheapest yet most complete toolkits use code Gamers Nexus for $5 off to bring that to 15 you can go to ifixit.com Gamers Nexus or click the link below for more information getting into this thing Intel's answer to our query which was why does this kbl Lake X exist was that it allows consumers to get into the high-end desktop platforms x299 at a lower price point so that they can upgrade later to the higher end CPUs this we think is a little misguided but that was their answer there are a few things we could speculate from here but first of all the misguided part here's the thing if you're spending $330 anyway on a CPU which is functionally the same as a 7700k except for actually they've stripped out the igp but otherwise functionally the same once you're at $330 on the CPU you're kind of out of territory where you're going to throw it away or even just move it to another build and buy a different one later because if you're spending 300 bucks on this and 300 plus on a board might even end up with a board that's more expensive than the CPU in this series of of chipset and platform once you are there it's time to stop pretending and Go properly highend this chip an i7 7740x is considered lowend when coupled with something like this and the 7700k which is what this is really isn't a low-end processor it's not but when you pair it with one of these it becomes a lowend processor and the pairing doesn't make any sense this is especially true for the I5 7640x which we will probably not be reviewing because it also it definitely shouldn't exist that one we know for sure should not be a CPU you can buy for this so one or the other uh either you have high-end CPUs for high-end boards or you fill both audiences which is kind of what the existing i7 line does so that's that's the positioning for these platforms and it's it's not a mid-step it's just weird this isn't like the g4560 where it might make sense to buy it with a z270 board and upgrade in a year now it's it's a bit worse than that CU you're spending so much money on the motherboard and half the features are unusable more realistically we think that Intel is trying to work toward merging its high-end Enthusiast products by eth generation we wouldn't be surprised if we start seeing things like the 7700k equivalent chips move permanently to x-class hardware at least if there's not enough push back but that answers why Intel thinks kbl Lake X exists of course shows that we don't necessarily agree but it's just ultimately more confusing for end users as for the differences between the 7700k and the 7740x here's a chart that shows them don't look too hard because there's really not many differences it's the base frequency that's the one the 7740x climbs to 4.3 GHz from 4.2 with Boost at 4.5 on both and they're still using dual Channel memory controllers despite being on the x3's platform so again only four dims are popul and also they're still both limited to 16 PCI E Lanes on the CPU itself the last major difference is that the socket type changed it's 2066 a few things with this the X Series chipsets are more expensive for the producer of the motherboard which means it's more expensive for you and the socket's more expensive just like amd's thread Ripper sockets more expensive it's more metal so it costs more money so the socket type changes you can't use one of these with the Z series platforms otherwise this might make a little more sense as just a standard refresh nothing wrong with 100 mahz bump but it's a little worse than that obviously because we're looking at a new motherboard one more big change though the igp again is gone so this is where Intel's argument gets a little nebulous because they have said uh the intention of these CPUs is to buy it discard it or relocate it and then put a better CPU in the system with the intention being to upgrade later if your intention is to upgrade later why not provide an igp if I'm the type of person who's going to upgrade a CPU later then I probably might want to just sit around and wait to buy a video card too and which case and igp would make this more arguable for Intel you can't do that here though there's no means of troubleshooting and look we don't normally like the igps we don't even talk about them in the reviews of the cas CU Parts but the reason it's being talked about now is because it was removed and I'm not sure there was a functional reason to do so so it does just kind of seem weird and it's not like the price went down for the consumer if this CPU were $30 cheaper than the 7700k that kind of makes sense and then you could at least mentally tell yourself okay it I'm saving $30 on the CPU so I can invest 30 more on the motherboard or something like that but that's not how it works here that should largely outline our stance on the CPU let's look at the Benchmark numbers starting with thermals and as always you can find our full test methodology link to the description below for thermals here we're using a kraken x62 completely maxed out on the fans and the pump we've used this for our thermals for some time now and we're also logging liquid temperature which allows us to look at the Delta between the liquid temperature the CPU package and the CPU cores so we can figure out how well the CPU die is transferring its heat to the IHS and then into the cooler starting with just the 7740x and its stock configuration with an AVX workload we found that the CPU tended to operate around 1.77 vcore when Auto VC cor was used on our Asus Prime board and it does change per board and that was with a CPU temperature peaking at around 75 to 76 cels on the package or about 74 to 75 C for a peak averaged core temperature in this time our liquid temperature only increases from about 29 or 30 C to about 35 C for a Delta of about 6C start to end of the test the last time we showed this data was for the 7700k review when we noted that the 7700k was running pretty hot even compared to it 6700 K predecessor part of this seems to be that there's poor transfer from the CBU die to the IHS on the cooler as the liquid temperature doesn't really move all that much even when testing it for an hour and again this is with a kraken x62 maxed out and we're still around 74 to 75c so this CPU runs hot if we were to drop the fan speed to around 1050 RPM which is pretty bearable and you can see in our CPU Cooler testing the temperatures would rise substantially to the point where it really wouldn't be worth dropping the fan speed and less powerful coolers wouldn't be as effective comparing now to the overclocked version of the CPU at 5.1 GHz with a VC core of 1.37 we're looking at a temperature that's bumping into the 100 Celsius TJ Maxx limiter causing severe clock drops that bring down our OC the chip can clearly handle it but we need a lot more than even a 280 mm cooler with maxed out fan and pump RPMs in a room with an ambient of about 22 to 23c so it's again pretty hot we just weren't stable below 1.37 volts and at least with the 5.1 GHz clock for AVX instructions but we were stable at 1.35 for non AVX instructions the next interesting comparison will be between the 7700k and the 7740x this is the last one we're publishing for now but we do have a lot more data to dig into for some future content for this comparison both CPUs are clocked to 4.5 GHz with a 1.2 volt vcore and we're running non-avx thermal tests to compare The non-avx Thermals between the C pus they're roughly the same when at the same voltage 1.20 volts with about a 68 to 70 Celsius range most differences in thermals between the two CPUs can be attributed to motherboard changes primarily motherboard Auto VC core that might run a higher voltage on one socket than the other more thermal discussion in the link in the description below as always but now we're going to move on to FPS test before getting to these this CPU again is basically a 7700 K so we're going to be comparing it primarily to a 7700 K to show when and if there are differences because of that there won't be a lot of discussion comparing it to other parts and that's not because we hate the other parts it's because they were compared against already in our ryzen 5 review so if you would like to see discussion on the non 77x X parts then check the R51 1600x review and check the I9 7900x review for the most upto-date data and comparison on all of those today it's a focus on the 277 blank chips 100k and 40x so that we can see how the scaling looks and if it's worth putting the 7700k on a 300 plus motherboard let's look at blender next the i7 7740x stock CPU completes our scene render in 42 minutes which is basically the same as the i77700 K's 42.4 minute result basically the same overclocking the 7740x gets us to 37.1 minutes for an improvement in performance of about 133% over Baseline then again you shouldn't buy either of CPS for blender rendering anyway it's just a good tool to look at the difference between them if rendering is the primary goal the r7700 would do significantly better at 33 minutes and would cost the same and then you could overclock it granted the i7 series CPUs do tend to hold an advantage in gaming but we'll get there looking at fire strike next the 7740x runs a physics frame rate of 4649 FPS with the 7700k stock CPU at 45.96 FPS this is within test to test variance actually and isn't really significant difference overclocking gets us to 5244 and 5216 FPS on the X and K excuse respectively both at 5.1 GHz so again the same sorting by physics scores instead shows us the same thing the 7740x with its 14,641 point2 ahead of the 7700k with time spy it's more of the same the 7740x stock CPU runs a CPU frame rate of 20 FPS with the 7700k stock CPU at .66 FPS for the same test that's a 1.7% difference overclocking gets us to 2188 FPS versus 21.4 FPS on the 7700k OC CPU ashes of the singularities our next synthetic test with dx12 and puts the 7740x stock CPU at 42.4 FPS 4our 1080p High test with lows at 33.9 and 31 FPS 0.1% the 7700k runs its average at 41.5 FPS lows 32.7 and 3091 and 0.1% that puts the 7740x at 2% ahead of the 7700k CPU a little bit boring there so we'll move on to Ash's escalation which we haven't fully updated with all our CPUs yet but it does have the 7700k stock CPU at 44.3 FPS average 36.4 1% lows and 33.2 0.1% lows the 7740x is measurably but imperceptibly better at 44.8 FPS average or 1.1% faster this change like all the others could largely be ch fed up to the fact that even just the motherboards are different so there might be differences in things like DPC latency and other aspects of the board Grand Theft Auto 5 isn't much difference the stock 7740x measured at 149 FPS average with 108 FPS 1% lows with the 7700k stock CPU at 149 the two overclock SKS are different by less than 1 FPS and are within test to test variants they are effectively identical there are more gaming results in the article normally we would go through at least one or two more of them here considering ashes is basically synthetic but to save you the time they're all the same the difference between these CPUs is barely there at all sometimes the 7700k is in the lead in some of the games sometimes this one's in the lead and when I say in the lead I mean the bar is bigger but that doesn't mean that it's outside of test variants and there's plenty of differences just in the motherboards for example the maturity of this chipset x299 is not quite as far along as z270 so there are instances where we saw improved performance on the 7700k z270 platform than on this one even though they're technically the same clock and some of that is the chipsets being different some of it is the maturity of the drivers but at the end of the day they will come out to be about the same FPS so no point in going through more of it as for the conclusion on this CPU the i7 7740x it's very plain and simple this isn't worth buying do not buy it uh if you want to buy a CPU that is really gaming focused from Intel the 7700k with a z270 makes a lot more sense the CPUs themselves are the same price let's say that this CPU Were Somehow obtainable or obtainable on the z270 platform if you could get one of these on z270 would it be worth buying well probably not it depends but ultimately even if they were on the same platform and they cost the same price and they were both being sold alongside one another what you end up with is a 100 MHz faster base totally Irrelevant for most of us because if you're gaming it's probably going to be pinned at 4.5 anyway and that's the same on both of them and you lose the igp and technically the TDP rating on this is higher on this one than the other uh I don't know why maybe the base clock pushes is it the extra 20 or so Watts or maybe they're just accounting for the high temperature scenarios that the 7700k exhibited but either way the only real difference is that igp and 100 MHz on the base so uh it's not worth buying it's a waste of money to get it for the x299 platform if you want to buy the x299 platform there are some really good motherboards out there putting this on it would just really be an insult to the boards so if you go x299 get a good board for it and then get a decent CPU for it it doesn't have to be a 10 core but something better than these so that you can actually use everything on the board and then uh then you have a platform that might be worth using there are still some reasons that x299 isn't perfect we talk about those in the 7900x review and he gives them quite a run for their money in the consumer department where you might be rendering in blender or whatever as a freelancer or a semi-professional or someone who doesn't work for a large studio where you have workstations with Intel products but for most of our audience things like rendering ryzen is quite good at it for things like gaming the 7700k is as good as this on a cheaper platform and it's way more streamlined and less confusing with more mature drivers a more mature chipset and the driver support from the motherboard vendors and they've gone through all their revisions to fix all the problems with the first round of boards so that's the best way to go if you don't want to screw around with things and you just want to play games with a high frame rate and that's it so that's all

.66 FPS for the same test that's a 1.7% difference overclocking gets us to 2188 FPS versus 21.4 FPS on the 7700k OC CPU ashes of the singularities our next synthetic test with dx12 and puts the 7740x stock CPU at 42.4 FPS 4our 1080p High test with lows at 33.9 and 31 FPS 0.1% the 7700k runs its average at 41.5 FPS lows 32.7 and 3091 and 0.1% that puts the 7740x at 2% ahead of the 7700k CPU a little bit boring there so we'll move on to Ash's escalation which we haven't fully updated with all our CPUs yet but it does have the 7700k stock CPU at 44.3 FPS average 36.4 1% lows and 33.2 0.1% lows the 7740x is measurably but imperceptibly better at 44.8 FPS average or 1.1% faster this change like all the others could largely be ch fed up to the fact that even just the motherboards are different so there might be differences in things like DPC latency and other aspects of the board Grand Theft Auto 5 isn't much difference the stock 7740x measured at 149 FPS average with 108 FPS 1% lows with the 7700k stock CPU at 149 the two overclock SKS are different by less than 1 FPS and are within test to test variants they are effectively identical there are more gaming results in the article normally we would go through at least one or two more of them here considering ashes is basically synthetic but to save you the time they're all the same the difference between these CPUs is barely there at all sometimes the 7700k is in the lead in some of the games sometimes this one's in the lead and when I say in the lead I mean the bar is bigger but that doesn't mean that it's outside of test variants and there's plenty of differences just in the motherboards for example the maturity of this chipset x299 is not quite as far along as z270 so there are instances where we saw improved performance on the 7700k z270 platform than on this one even though they're technically the same clock and some of that is the chipsets being different some of it is the maturity of the drivers but at the end of the day they will come out to be about the same FPS so no point in going through more of it as for the conclusion on this CPU the i7 7740x it's very plain and simple this isn't worth buying do not buy it uh if you want to buy a CPU that is really gaming focused from Intel the 7700k with a z270 makes a lot more sense the CPUs themselves are the same price let's say that this CPU Were Somehow obtainable or obtainable on the z270 platform if you could get one of these on z270 would it be worth buying well probably not it depends but ultimately even if they were on the same platform and they cost the same price and they were both being sold alongside one another what you end up with is a 100 MHz faster base totally Irrelevant for most of us because if you're gaming it's probably going to be pinned at 4.5 anyway and that's the same on both of them and you lose the igp and technically the TDP rating on this is higher on this one than the other uh I don't know why maybe the base clock pushes is it the extra 20 or so Watts or maybe they're just accounting for the high temperature scenarios that the 7700k exhibited but either way the only real difference is that igp and 100 MHz on the base so uh it's not worth buying it's a waste of money to get it for the x299 platform if you want to buy the x299 platform there are some really good motherboards out there putting this on it would just really be an insult to the boards so if you go x299 get a good board for it and then get a decent CPU for it it doesn't have to be a 10 core but something better than these so that you can actually use everything on the board and then uh then you have a platform that might be worth using there are still some reasons that x299 isn't perfect we talk about those in the 7900x review and he gives them quite a run for their money in the consumer department where you might be rendering in blender or whatever as a freelancer or a semi-professional or someone who doesn't work for a large studio where you have workstations with Intel products but for most of our audience things like rendering ryzen is quite good at it for things like gaming the 7700k is as good as this on a cheaper platform and it's way more streamlined and less confusing with more mature drivers a more mature chipset and the driver support from the motherboard vendors and they've gone through all their revisions to fix all the problems with the first round of boards so that's the best way to go if you don't want to screw around with things and you just want to play games with a high frame rate and
