As next-gen CPUs quickly approach, we've updated all our CPU benchmark data and have retested some Intel CPUs to highlight DDR5's impact on modern PC gaming performance.

DDR5 problem is not performance, it's density, you can't run 4 sticks with it, 128 GB+ configuration without ECC is unheard of in DDR5, even if "officialy" the mobo says it's able, in DDR4 you can do it easy and on many diffrent mobos...

is that why I see ddr5 for sale in 4 packs but sticks are dummy ones?DDR5 problem is not performance, it's density, you can't run 4 sticks with it, 128 GB+ configuration without ECC is unheard of in DDR5, even if "officialy" the mobo says it's able, in DDR4 you can do it easy and on many diffrent mobos...

Jeez 7800X3D is really, really good in games. Batters the 14900K even when the Intel chip is using very fast DDR5. Be interesting to see how well it ages. AMD are going to keep throwing cache onto their chips when the performance gains to be had for gaming are so huge.
sure would like to hear about that actually working in a complete system not just working in the pack
The comment about not making sense to get DDR4 is debatable when you consider the price difference. Essentially, you are paying about 2x the price for DDR5, for 20% gain on average. So from a cost benefit angle, people may still go with affordable DDR4 3200, since there is little difference going up to 3600.

For slower cards , this article shows no need of DDR5 . Yep , in the future it would be inevitable as well as even faster RAM .

The rise of the core count of the processors necessitates higher memory bandwidth . That s why DDR5 is invented and serves this purpose . You need DDR5 if you re planning to have a top-notch rig otherwise DDR4 is stil fine . The shift to faster memory in the future is inevitable of course .

I fancy an idea to replace my 5600mhz ddr 5 with 7600mhz +.
But I liked corsair dominator brand so much that I am hesitant.
I do not want to buy grossly overpriced but faster dominator,
and I do not want to replace my lowe speed dominator sticks with
a generic looking RAM from other brands.

Step down to a 7700xt or comparable GPU and the argument won't work so well. One will never see the average boost of 16% with a mid class GPU.
Raise your resolution one step further and the differences between RAM gens also decrease.
Combine those two and... well, you get the point.
Still, some time in the future faster RAM will be necessary. What we can see in this article is just the proof for that. 4090 and faster GPUs of the future will scale. But this is academic for most of the users today. Don't expect those gains when you switch platforms, unless you are using very expensive GPUs at lower resolutions NOW and somehow managed to skip DDR5.

What are you talking about??? What do you mean you can't run 4 sticks of DDR5???DDR5 problem is not performance, it's density, you can't run 4 sticks with it, 128 GB+ configuration without ECC is unheard of in DDR5, even if "officialy" the mobo says it's able, in DDR4 you can do it easy and on many diffrent mobos...
you need 360 support
mobo must be able, ram must be able and memory controller must be able, this problem make it impossible to really run 128 192 and 256 giga without ECC on any mobo, but I think Intel has better luck with it than AMD...

So the short version take away is that the increased performance cost isn't worth the extra cost, yet.
True, but factor in those extra costs of more expensive board and ram kits and the bump in performance isn't so shiny anymore.
Can we stop these crazy benchmark tests, please?
You've built $3000+ machines, and tested the difference at 1080p? No one who spends that much money wants 1080p gaming.
People buy 4090s for 4k gaming with all the settings turned up. It would be actually helpful in the real world to know how much the memory change affects that... That would be an excellent article!

Now do this wih CAMM2 ram when it releases on desktop, I wan't to know if there is any benefit to CAMM2 on desktop other than space saving and 1 module instead of 4.
When DDR5 was first introduced to the retail space, some games that could utilize the higher bandwidth resulted in higher performance. If I am not mistaken Watchdog Legions was one of such games. Hence with newer games, the faster DDR5 will benefit performance due to optimization. However, it really depends on your use case because the benefit is not always consistent across games. The ones here are just but a handful. The review just illustrates that the potential is there.But again to my earlier point, it comes at a fairly steep increase in price over DDR4. So if someone is on a tighter budget, it is not something I would recommend stepping up for, because in the case of Intel boards, the DDR5 boards also tend to cost more than the DDR4 versions.

Hey TechSpot crew. Been on a roll with good, useful articles lately. Well done.
It's so nice to be reading about tech and not politics. Keep it up!

amen
amen again
Show some bechmarks at 4k with something that's not a 4090.
DDR speed depends on how good your mobo and cpu is. Most of the RAM is SK hynix 16 Gbit A-Die. Get 6000 for stability. Anything over 6800 you might not even get XMP to work. Showing 7200 and making people think they can just drop that in, is misleading a lot of readers who might not be experts in DDR. I'm not either but I watched one interesting video.
Who on earth games in 1080p on 4090.
Who on earth wants to read about 1080p gaming.

no 7800x3d isn't beating intel ... test use 6000mhz stick and oc at 7200mhz. there is not that big difference between good 7200 mhz ram and 8200 mhz ram and the difference between such ram against 7800x3d intel is ahead of 30 fps at 4k. the main goal of high frequency memory is the bandwidth and if you oc a ram to 7200 but have 6000 mt/s bandwidth there is no performance gain.
here some difference between such ram at 1080p low
here a 7800x3d with amd boost enabled at 4k
now a 14900k crushing the 7800k at 8k resolution ... we're not talking about 4k vs 4k but the 14900k even at 8k resolution beat the 7800xed at 4k resolution ... with 8800mhz sticks
see the difference when you use real ram stick instead of oc low bandwidth ram
This is just the remove the GPU possible bottleneck of the equation but I agree, would have been nice to have less games but with 1440p and 4k to see what the differences are.
Previous tests show that with a higher resolution and not a top GPU like the 4090, the differences are minimal at best.
So this situation shows the best potential of DDR5. Reality (higher res + mid GPU) is a lot different.
