Gaming Performance: 720p And Lower
The reason we test games in CPU reviews at lower resolutions such as 720p and below is simple; titles are more likely to be CPU bound than they are GPU bound at lower resolutions. This means there are more frames for the processor to process as opposed to the graphics card doing the majority of the heavy lifting.
There are some variances where some games will still use graphical power, but not as much CPU grunt at these smaller resolutions, and this is where we can show where CPU limitations lie in terms of gaming.
We are using DDR5 memory on the Ryzen 7 78000X3D and the other Ryzen 7000 series we've tested. This also includes Intel's 13th and 12th Gen processors. We tested the aforementioned platforms with the following settings:
- DDR5-5600B CL46 - Intel 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
All other CPUs such as Ryzen 5000 and 3000 were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.
Civilization VI
World of Tanks
Borderlands 3
Grand Theft Auto V
Red Dead Redemption 2
F1 2022
Hitman 3
Total War: Warhammer 3
Now let's talk about gaming tests, which is where the Ryzen 7 7800X3D really shines. At 720p resolution, where a strong CPU matters more than a high-end graphics card, this processor performs exceptionally well. It outperforms the Ryzen 7 7700 and can even compete with higher core count chips such as the Ryzen 9 7950X and the Core i9-13900K in certain games. Overall, the Ryzen 7 7800X3D delivers impressive 720p gaming performance.

Literally every person with a brain is using memory that is technically "overclocked", and has been for over a decade. XMP/DOCP are overclocking... they're also mandatory for decent performance and a realistic test setup.NO ONE should be using 5200-CL44 in 2023.

Yea it kind of defeats the point on having otherwise state of the art hardware.erotomania - Tuesday, April 11, 2023 - link
I haven't much liked that part of AT testing for a while, nor the explanation.elajt_1 - Friday, April 7, 2023 - link
And yet AMD themselves suggest 6000MT/s as it is the sweet spot according to them.spikebike - Wednesday, April 5, 2023 - link
Can you RMA a CPU and/or motherboard because it doesn't like your DDR-6000?Do you include over/under volting? Exotic cooling? Pushing things hard enough that system reliability is compromised? Crazy large power supplies?
Or do you compare all CPUs/platforms with their posted specifications?
Comparing AMD *AND* Intel at their posted specifications seems fair. After all not everyone overclocks, and I don't particularly care if AMD or Intel is better at overclocking. After all some people actually like reliable computers and might actually care more about ECC memory than performance from overlcocking.

That's a fair comment, but these are enthusiast level parts after all.I suppose the solution is to show performance in both scenarios.

"I suppose the solution is to show performance in both scenarios."In an ideal world, it's something we'd like to do in some fashion. But it would double our testing workload, which isn't viable.

That's also fair enough. I appreciate the time taken to address comments.elajt_1 - Friday, April 7, 2023 - link
The people who gets these CPU's witout running OC memory can most likely be counted on one hand.elajt_1 - Friday, April 7, 2023 - link
Expo and XMP profiles will work on most systems (if not all), up to a certain speed.
