Amazing Ryzen 7 Pro 4750G Mini ITX Gaming Build! No Video Card Needed👍

**Testing the Performance of an AMD Ryzen 4700G Mini-ITX Build**

The AMD Ryzen 4700G is one of the most powerful integrated GPUs available, and it was put to the test in this small form factor build. The goal was to see how well the 4700G would perform in various games and applications, despite not having a dedicated GPU.

**Forza Horizon 4 at 1080p Low Settings**

The first game tested was Forza Horizon 4, which is an arcade racer that requires a strong graphics card to run smoothly. However, with the integrated 4700G, the game still looked great and ran well. The average frame rate at 1080p low settings was 68 FPS, which is a respectable performance for a small form factor build.

**CS:GO at 1080p High Settings**

Next up was CS:GO, a popular multiplayer shooter that requires high-performance hardware to run smoothly. With the 4700G, the game ran well and maintained an average frame rate of 121 FPS at 1080p high settings. This is impressive performance for a small form factor build.

**Skyrim Special Edition at 1080p High Settings**

The Elder Scrolls V: Skyrim Special Edition was also tested, and it proved to be a challenging game to run on the integrated GPU. However, with the 4700G, the game ran smoothly and maintained an average frame rate of 60 FPS at 1080p high settings.

**GTA V at 1080p Normal Settings**

Grand Theft Auto V was also tested, and it ran well with the 4700G. The average frame rate was 66 FPS at 1080p normal settings, which is a great performance for a small form factor build.

**Remastered at 1080p Low Settings**

The Remastered version of Skyrim was tested, and it proved to be a challenging game to run on the integrated GPU. However, with the 4700G, the game ran smoothly and maintained an average frame rate of 32 FPS at 1080p low settings.

**Doom Eternal at 1080p Low with Resolution Scaling**

Doom Eternal was tested with resolution scaling enabled, which helps to reduce the load on the integrated GPU. With the 4700G, the game ran well and maintained an average frame rate of 66 FPS.

**Cyberpunk 2077 at 720p Low Settings**

Finally, Cyberpunk 2077 was tested at 720p low settings, which is a significant reduction in resolution compared to the other games. However, with the 4700G, the game still ran well and maintained an average frame rate of 42 FPS.

**System Power Consumption**

The system power consumption was also tested, and it proved to be relatively low. At idle, the build consumed around 23 watts of power, which is impressive for a small form factor PC.

**Extreme Test: Cyberpunk 2077 at 4K Resolution with High Settings**

However, when running Cyberpunk 2077 at 4K resolution with high settings, the system consumed significantly more power. The average power consumption was around 79 watts, and the maximum power consumption reached up to 153 watts during an extreme test scenario.

**CPU Temperatures**

The CPU temperatures were also tested, and they proved to be relatively low. At idle, the temperature was around 36 degrees Celsius, which is impressive for a small form factor build. However, when running demanding games like Cyberpunk 2077, the temperature did rise to around 42 degrees Celsius.

**Noise Levels**

The noise levels were also tested, and they proved to be relatively low. At idle, the system was almost completely silent, but during gaming, the fans would kick in slightly to maintain a reasonable temperature.

**Conclusion**

Overall, the AMD Ryzen 4700G performed well in this small form factor build, despite not having a dedicated GPU. The system was able to handle demanding games like Forza Horizon 4 and CS:GO at high settings, while also running other applications smoothly. However, it's worth noting that extreme tests like Cyberpunk 2077 at 4K resolution with high settings will push the system to its limits and increase power consumption.

**Future Plans**

The author has plans to create a video showcasing emulation on this build, including playing games like Wii U and PS3 using an emulator. This will be a fun experiment to see how well the 4700G can handle demanding emulators and games.

**Building a Similar PC**

If you're interested in building a similar PC to this one, the author recommends using the AMD Ryzen 4700G as the CPU. It's one of the most powerful integrated GPUs available, and it will provide great performance for gaming and other applications. The author also recommends using a small form factor case like the In Win B1, which is designed specifically for compact builds.

**Conclusion**

In conclusion, the AMD Ryzen 4700G performed well in this small form factor build, despite not having a dedicated GPU. With its high clock speeds and integrated graphics, it's capable of handling demanding games and applications smoothly. However, extreme tests like Cyberpunk 2077 at 4K resolution with high settings will push the system to its limits and increase power consumption.

"WEBVTTKind: captionsLanguage: enhey what's going on guys cta prime back here again today we're going to be building a small form factor amd apu powered mini pc now with this build here we're going to be using a case that i've had my eye on for a little while i've actually had it in my possession for about a month but i haven't gotten around to building in it this is known as the n-win b1 now i do have to admit that when i first saw this online i wasn't a big fan of it and still looking at pictures online it really doesn't do it justice but after getting this in my possession and taking it out of the box i think it looks like a really nice little case it's definitely really different from other mini itx cases on the market and it does resemble kind of a turret from portal and with a price of 85 dollars does come with a 200 watt power supply but the main thing i'm concerned about with this unit here is cooling because there's not much ventilation it does come with a single 80 millimeter fan to exhaust all that heat out but the maximum clearance on the cpu heatsink is only 60 millimeters and for this build here we're actually going to be throwing in eight cores and 16 threads with the ryzen 7 4750g so we got those eight cores with a base clock of 3.6 gigahertz and a boost up to 4.4 plus we have the built-in radeon 8 graphics running at 2100 megahertz ram is going to be covered by 16 gigabytes of team force delta r running at 3600 megahertz but i've been able to overclock this and another system up to 4 000 and we'll definitely try it with this because the faster we can get that ram the better performance we'll get out of these built-in radeon graphics storage is going to be handled by a 512 gigabyte m.2 it's a z340 by team force and i also have another 500 gigabyte 2.5 inch ssd from pny for the motherboard i went with the rog strix b550i gaming and one of the big reasons i wanted to choose something like this a b550 versus an old 450 was this actually supports the 4750g right out of the box i didn't have to update the bios or anything like that and finally for the cooling solution i'm going to be going with the id cooling is 47k this is 47 millimeters tall so we do have plenty of room inside of this case that only supports up to a 60 millimeter heat sink and i've actually tested the same heat sink in the new asrock desk mini running a 4750g and it'll definitely keep this cpu cool as long as we have that ventilation so if all works out this will be the cooler i'm going to be using if not i'll have to resort to something else but i think we'll be good with this whole setup so first things first i wanted to give you a look at this case here it's actually really interesting the way they've set this up the whole top comes off we have that tempered glass on top i kind of wish they would have offered one with mesh instead of tempered glass but at the time of making this video they do not as you can see inside of here we have a 200 watt power supply a pre-installed 80 millimeter fan and looking at all this wiring inside of here hopefully i can clean this up really nicely it does look like a mess right now but i think once everything's put together and a little bit of zip tie magic is thrown on this thing we can clean it up really nicely and the bottom is actually removable and it'll fit two 2.5 inch hard drives or ssds so we do have a lot of storage options with this mini itx case all right so let's go ahead and start the build first thing we're going to start off with here is the m.2 ssd there's a spot on the bottom but i'm going to throw this one on the top just in case i want to add another one later on down the road i cannot access this once it's all put together so i'm just going to throw this 512 gigabyte unit here first all right so now that we have the m.2 out of the way it's time to throw this cpu in we're using that 4750g now these can be obtained on ebay you can go gray market with it that's exactly what i did sometimes you can find a good deal on them sometimes they're a bit overpriced so it's really hit or miss with this cpu but i'm a big fan of this thing performance is absolutely amazing for an apu now it's time to mount this cpu cooler on here and it is a bit of a pain because it kind of covers the whole board here so i'm going to go off camera just to get this on i do have to do it upside down and backwards to get this mounted correctly and as you can see that cpu fan is actually mounted to the bottom of the heatsink itself and it pulls air up and pushes it through the heatsink instead of pulling air in i still have full access to my ram slot but as you can see it is covering up that m.2 slot and that's why i had to put that in before i did anything else so i'll go ahead and put my ram in here and this is the delta r from team force it is rgb on the top and i'm not a big fan of rgb but i did have this laying around and i think it might look pretty good inside of this case given that we have that glass top i think adding a little bit of color to this setup will make it pop a bit now it's time for the fun part fitting all this inside of this super small form factor case i've already put my i o shield in here mainly what i need to look out for is just pinching any wires and clearance i have not measured this but i really think that everything's going to fit in here the main thing i was worried about here was the clearance on the heatsink but this is a 47 millimeter heat sink but they claim you can use up to a 60 so i think we'll be good to go with this one it's definitely looking a bit tight in here but after all i mean this is a mini itx case and uh it fit in here so all i need to do is bolt it down get all my wires plugged in and clean it up and yeah after a little bit of cable management it came out way better than i thought it would be i figured we'd have wires all over the place but with a couple zip ties i think it looks pretty good now before i start this up for the first time there's one last thing i need to do here on the bottom you can actually remove these feet if you just want to use it in the vertical position but we need to install that 2.5 inch ssd and they make it really easy this fits two 2.5 inch mechanical hard drives or ssds and from here i can actually get to the other m.2 slot on the motherboard so with this setup you can add a ton of storage so i've got everything installed everything's cleaned up i've placed the top on the unit it's time to boot this up for the first time we do have a power button right on the front of this thing so i'll go ahead and press it so we got the rgb going on that ram and i think it looks pretty good now i haven't removed the rear feet because i'm not exactly sure how i'm going to be placing this but i think it might be in the vertical position like you're seeing now i think it looks really great like this now i need to go ahead and get all my software installed and we'll get right into some testing all right so here it is i've installed windows 10 pro i've got a lot of applications that i want to test out and some games now one thing that i've noticed is this cpu is actually registering as the 4700 g and if i head over to the amd website i would no longer see the 4750g little weird there but even on the chip itself it stated that this is a 4750g either way you look at it i don't think there's any difference between the two we still have eight cores 16 threads base clock of 3.6 with a boost up to 4.4 we got 16 gigabytes of ddr4 ram and i have overclocked this the 4 000 megahertz and the built-in amd radeon a graphics even in cpu-z it's telling me that this is the ryzen 7 pro 4700g and in gpu z it's telling us that the gpu clock will go up to 2100 megahertz but it's weird because when playing a game and i have afterburner running it's stating that the gpu is actually going to 2200 megahertz and i haven't changed any of the settings in the bios except for the ram speed so whenever i build one of these machines a lot of this is really dedicated towards gaming but using this as an everyday desktop you'll have no issues whatsoever we'll just head over to amd's website you see i mean it loads up super quick and on the 4000 series page you see we have the 4700g here i don't see the 4750 listed anymore 4k video playback on something like this is going to be no issue whatsoever just head over to this video here make sure we have stats for nerds going full screen and just to show you we are at 4k you have a couple drop frames when you first start off but it's gonna play 4k 60 all day long whether you're streaming it with your favorite apps be it netflix youtube plex or you're playing it natively from a hard drive or a nas i mean this has more than enough power to do 4k video playback at 60fps so far i've been really impressed with the performance here i did run some benchmarks and i tested out some games first thing we're going to take a look at are benchmarks first up we have geekbench 5 single core coming in with 1180 multi 7947 taking a look at pc mark 10 total score of 5616 and as you can see from the chart here it's better than 69 of all other systems tested with pc mark 10. 3d mark night raid 18041 fire strike coming in at 4 398 and finally time spy coming in with an even 1700 now this might not look that impressive on paper when you see other higher scores with dedicated gpus installed but keep in mind these are integrated graphics we're working off that cpu with the built-in radeon 8 graphics and for what it is i think these scores were pretty decent but now i really want to put it to the test and run some of my favorite pc games and see how this thing performs first up we have forza horizon 4 1080p low settings and i got an average of 68 fps with this one and this game even on low looks really great for an arcade racer next up we have cs go 1080p high settings by the end of this i had an average of 121 fps fully playable it runs great here and if you want to get a better frame rate out of it you could drop those settings down but i think this is running great next we have one of my favorite games skyrim this is actually the special edition version 1080p high settings it'll run at 60 all day gta 5 1080p normal settings i think it did a pretty good job here at the end of this i had an average of 66 fps so if you just wanted to turn vsync on and play this at 60 it'll do it just fine remastered i was actually pretty impressed here i've tried this on lower end machines and it's just a hard game to run even at 1080p low but we did get an average of 32 out of this one doom eternal 1080p low with 100 resolution scale this uses the vulcan back end we got an average of 66 fps out of it and finally we have cyberpunk 2077 originally i wanted to do this at 1080p but it was around 23 to 24 fps so i did drop this down to 720p low and i got an average of 42fps out of this and it's still pretty impressive given the fact that these are integrated graphics running cyberpunk 2077. taking a look at total system power consumption from the wall using a kilowatt meter at idle it averages around 23 watts 4k video playback 31 gaming around 79 watts and the maximum that i could get this to pull from the wall was actually way higher than i thought it would be at 153 watts now that's an extreme use case scenario all eight cores 16 threads and the built-in radeon 8 gpu were totally maxed out but i really wasn't expecting this system to pull over 130 from the wall but as you can see in that extreme test it did 153 watts like i mentioned at the beginning of this video i was really worried about cpu temps given that we're in this enclosed case the in-wind b1 with that is47k cpu cooler basically the only air outlet we have is that 80 millimeter fan that's in the case itself but it did a really good job idle we averaged 36 degrees celsius 4k video playback it did jump up to 42 gaming we averaged 68 and in my extreme test i was able to make this thermal throttle at 90 degrees celsius but again that's an extreme test under everyday normal use or even heavy use with 1080p gaming you'll never see those kind attempts and you'll be totally fine with this unit as for noise it's not bad at all idle and 4k video playback i really can't hear this thing it does ramp up a bit when you're gaming at 1080p but overall i think the noise that this does put out is totally justifiable given that we have such a small form factor pc here so yeah i'm really impressed with the performance of this build given that we don't have any dedicated gpu it's definitely a small form factor unit and i'm really digging this in win v1 case cena in pictures really doesn't do it justice it's actually a really good looking mini itx case i know my regular viewers want to see how this handles emulation so i do have a full emulation test video coming up definitely stay tuned to the channel i got a great feeling here that we'll even be able to do wii u and ps3 with this setup just like it sits but that's gonna wrap it up for this video i really appreciate you watching if you're interested in putting something like this together i will leave links in the description when it comes to that 4700g or the 4750g just keep an eye on ebay make sure you pick one up at a decent price because you don't want to overpay and the scalpers are definitely raising the price on these things but they do show up every once in a while for a reasonable price and if you're looking to build a small form factor pc like this i'd say this is one of the best cpus you can use right now but that's it for this one if you have any questions or you want to see anything else running on this unit just let me know in the comments below and like always thanks for watching youhey what's going on guys cta prime back here again today we're going to be building a small form factor amd apu powered mini pc now with this build here we're going to be using a case that i've had my eye on for a little while i've actually had it in my possession for about a month but i haven't

do have a full emulation test video coming up definitely stay tuned to the channel i got a great feeling here that we'll even be able to do wii u and ps3 with this setup just like it sits but that's gonna wrap it up for this video i really appreciate you watching if you're interested in putting something like this together i will leave links in the description when it comes to that 4700g or the 4750g just keep an eye on ebay make sure you pick one up at a decent price because you don't want to overpay and the scalpers are definitely raising the price on these things but they do show up every once in a while for a reasonable price and if you're looking to build a small form factor pc like this i'd say this is one of the best cpus you can use right now but that's it for this one if you have any questions or you want to see anything else running on this unit just let me know in the comments below and like always thanks for watching you\n"
