Is DDR5 a Game Changer For iGPU Gaming Performance?

**Unveiling the Intel UHD 770: A Gaming Powerhouse**

In this video review, we'll be taking a closer look at the Corsair H150i Elite LCD's gaming performance using the Intel UHD 770 integrated graphics processing unit (IGPU). We'll explore its capabilities in various games and examine how different memory configurations impact its performance.

**Initial Impressions**

Currently testing the Intel UHD 770 with 1080p settings on GTA V, we notice that the CPU is relatively underutilized. The GPU, however, is performing admirably, reaching speeds of up to 100% utilization in this game. We also run Battlefield 5 at 720p low settings, which showcases the IGPU's impressive capabilities.

**Baseline Benchmarks**

With our current configuration running at 26.66 MHz memory speed and DDR4 RAM, we achieve surprisingly good gaming results from the Intel UHD 770. However, we're intrigued to see how it performs with higher memory frequencies.

**Cranking up the Memory Speeds**

We decide to boost the memory speed to 3600 MHz, using the same timings as before. This increase yields a 10% performance gain across the board. We then upgrade our RAM kit to DDR5, running at 4400 MHz initially and later increasing it to 5200 MHz.

**Performance Comparison**

While we don't see a significant difference in performance when moving from DDR4 to DDR5, we do notice that higher memory speeds have minimal impact on the IGPU's performance. There are two primary reasons for this:

1. **Latency**: Our tests reveal that even with faster RAM speeds, the additional latency introduced by running at higher frequencies doesn't significantly benefit the IGPU.

2. **Memory Bandwidth Saturation**: The current memory bandwidth requirements of the Intel UHD 770 are largely saturated, making it less sensitive to increased memory speeds.

**Future Implications**

While we don't see a substantial performance boost from switching from DDR4 to DDR5 at present, we speculate that future architectures, such as RDNA 2-based IGPU's from AMD, might necessitate higher memory bandwidth. In these cases, the difference between slower and faster RAM speeds could become more pronounced.

**Conclusion**

The Intel UHD 770 offers impressive gaming performance, especially considering its relatively modest specifications. As we continue to explore the capabilities of this IC, we're eager to see how it compares to future architectures that may require higher memory bandwidth. For now, however, the IGPU's performance remains a great value proposition for those seeking reliable gaming solutions without breaking the bank.

WEBVTTKind: captionsLanguage: enthe moment that i first heard the ddr5 was going to see the light of day with intel's new platform launch my first thought was igpu gaming performance because igpus do scale quite well with memory bandwidth so what happens when you throw ddr5 at it that's what we're going to test in today's video and corsair was nice enough to sponsor this video with their super sexy new dom platz ddr5 which is the best ddr5 i can't help but be physically aroused every time i interact with this memory kid tastes like winning other than that corsair also wanted me to talk about this bad boy which is the h150i elite lcd that has an ips display right on the pump block super high tech stuff and it's just a big 360 mil epeen beast cooler so we're going to be talking about both these products intermittently over the course of today's video but with that let's get into some igpu gaming the igpu that we're going to use for all of these tests is the intel uhd 770 because well it's the only igpu available at the moment that will mingle with ddr5 so we don't have much of a choice although i've never gamed using the uhd770 before so i am very excited to see how it stacks up now the cpu that the igpu is going to be attached to for these tests is the i-912 900k because we just want to be 100 sure that there's going to be no cpu bottleneck now in terms of memory configurations we're going to test from ddr4 2666 megahertz all the way up to ddr5 5200 megahertz to see how the uhd 770 scales with additional memory bandwidth available to it uh now because of how the z690 platform works we are gonna have to use two different motherboards for the ddr5 and ddr4 test for the ddr4 test i went out and bought a gigabyte z690 udax ddr4 uh which on the surface seems like a very promising budget z690 board although i did have some problems with it it just refused to read nvme drives out of the box i tried various drives and it just wouldn't read them i ended up fixing this problem by just updating the bios but somebody in newegg's product review section said that just disabling intel vmd also fixes the problem either way it was a relatively easy fix but anyway so that's the motherboard that we're going to be using there in terms of the ddr5 setup i'm going to be using this asus z690 strix board which i used in a previous video which was kindly sent over by micro center micro center the right choice now moving over to the ram kits that we're going to use for these tests which is the important part that's essentially what we're testing there is a little bit of a discrepancy in capacity between the ddr4 and the ddr5 kits i only have one 64 gig kit of ddr4 and it completely refused to tango with that gigabyte board they must have had a brutal breakup or something because they did not like each other at all the only speed that i could get to boot was 26 66 megahertz for some reason uh even 2400 wouldn't boot it's weird that a slower speed wouldn't boot but but anyway i i couldn't get it working so i ended up having to use a core circuit which worked straight out of the box the ddr4 kit that we're using is this vengeance rgb pro sl kit that can run up to ddr for 3600 megahertz which is only a 16 gig kit as opposed to the 64 gigs of ddr5 that we're using but i did test 16 versus 64 gigs with the ddr4 configurations running at 26.66 megahertz and well if anything the 16 gig kit was a bit faster so the additional capacity of the ddr5 kit shouldn't affect the tests too much but just bear that in mind now moving over to the ddr5 we are using the amazing dom platz that was sent over by corsair it is a 64 gig kit that can run up to 5200 megahertz and you know the the beautiful rgb illumination on it will give you at least 15 percent additional performance fun fact in terms of this ddr5 dom platz kit this is actually the same ram kit that shroud's uncle used to teach him how to play cs go so some prestigious stuff right there and then the final thing in terms of test setup that i want to mention is the cooler which is going to be the corsair h150i elite lcd which is going to give us some some freezing cool gaming temperatures but anyway with that let's see how the uh how the uhd 770 stacks up in terms of gaming performance using ddr4 running at 26 to 66 megahertz okay so currently this is 1080p uh with all normal settings which with gta 5 is basically low and wow this is pretty good you can see that the cpu is not doing a whole lot there's not much happening uh but you'd hope that that's the case with a 12 900k and then the igpu is is pretty much is pretty much at 100 this is a good showing actually this is this is nice hey would you look at that battlefield 5 at 720p low settings is oh tank oh tank but it's kind of playable damn this new intel igpu is does not mess around so with that let's have a look at some actual baseline benchmarks wow that is a surprisingly usable gaming result from an intel igpu i'm really impressed and that's with the ram running at 26.66 megahertz and aside from gta 5 weirdly benefiting from having less ram the capacity differences had a negligible effect on the gaming performance so now i'm going to clock it to 3600 megahertz i'm going to be using the same timings as i did with the 2666 configuration and both of the configurations are also running at gear one going up to 3600 megahertz gives us about a 10 performance increase across the board which is not bad considering that it's it's just a memory frequency bump so now we need to drown that little uhd 770 in memory bandwidth using ddr5 okay so we've got our corsair ddr5 in here i've strapped myself in with a seat belt for the speeds now the kit is currently running at 4 400 megahertz so this isn't its full speed uh we're gonna up that to 5200 megahertz soon oh yes this is some good igpu performance we've got going here there is the occasional small dip below 50 frames per second but yeah this is good this is good so let's look at some benchmarks okay not a massive difference but it is running at 4 400 megahertz here so let's crank it up to 5200 megahertz and see if that helps oh yeah it's a little bit embarrassing ddr5 didn't make a huge difference in terms of performance here but i think there are a couple of good reasons for that the first one is for the ddr4 configurations i could easily run even the faster speed kit in first gear in gear one which is the lowest latency configuration you can run your ram in whereas ddr5 i could only get running with gear 2 regardless of the the memory speed that i was running uh so that additional latency seems to negate the additional memory bandwidth that we get from the higher speed ram so i think that's the first reason we didn't see a huge difference and i think the second reason we didn't see a huge difference is that even with the fast ddr4 the igpus memory bandwidth need is kind of saturated that's not the bottleneck anymore that's not the reason why it's not performing better anymore and i think that's why going from 4 400 megahertz to 5200 megahertz the results were pretty much within the margin of error so i think what's going to happen is when we get higher performance eye gpus something like rdna 2 based igpus from amd we may actually see a bigger performance difference going from slower ddr4 to like high speed ddr5 you know if if those architectures need more memory bandwidth for their performance but at this point that's just a guess right i don't know if that's going to happen or not but yeah an interesting result thank you very much for watching thank you corsair for sponsoring this video that's very awesome of you sending over huge amounts of ddr5 and stuff for this video i really appreciate it and until the next video like and subscribe to the channel if you want more videos like this one and until the next video byethe moment that i first heard the ddr5 was going to see the
