CPU Benchmark Performance: Science
Our Science section covers all the tests that typically resemble more scientific-based workloads and instruction sets. For our 2023 CPU suite, we've also added SciMark 2.0 which measures numerical kernels and various computational routines found in numeric coding.
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.
Science
Looking at the performance of the Ryzen 7 7800X3D in our scientific-based workload testing, we can see that the 7800X3D is comparable to its lower-powered and 3D V-Cacheless Ryzen 7 7700 sibling. As we would expect from a newer chip, we can see that the Zen 4-based Ryzen 7 7800X3D for the most part beats out the Zen 3-based Ryzen 7 5800X3D.

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.
