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.

Your test results make absolutely no sense, none.MetalScythe - Sunday, April 9, 2023 - link
Especially compared to -every- other publication that’s reviewed this CPU. Going by this review, you’d think it’s crap at gaming. Pure insanity.zodiacfml - Thursday, April 6, 2023 - link
with this logic, its the i3s and 5600g are the winners as the performance/price is highest. I'm quite impressed they're holding up well even at the lowest resolutions or fastest GPUs.Ruklaw - Thursday, April 6, 2023 - link
Are the power readings derived from what the processor itself is reporting?My impression is that AMD processors tend to under-report, as the low power readings from the cpu don't quite seem to match up with the readings of whole system power where I've been able to find them.
Obviously motherboard is going to be a big factor in how much power the system uses but with all else being equal the system power is going to be more representative of what we actually have to deal with (in terms of heat and energy cost).

I’m genuinely baffled by your testing, you kneecapped Intel to give AMD a win; who the hell buys a 13900KS and uses crap memory?Worst test I’ve ever seen.

The memory we used, that is following a long-standing testing policy with the site. We test CPUs with the fastest memory they officially support. Overclocked memory a) Voids your processor warranty, and b) Isn't guaranteed - which is to say that you can't RMA a chip because it doesn't overclock to some specified frequency.We've had discussions with AMD and Intel on the matter before. If they change these two policies, we'd be happy to update our testing policies to match. Otherwise, our preference is to stick to settings that won't break your processor, and represent a level of performance that all chips will attain, rather than a level of performance that a subset of chips may attain.

Wel. Your comment can get to the usual list of worst as usual.It is clearly explained why and used for a long time for years.
Who the hell buys the worst cpu ever the 13900ks anyhow... Yes stupidity exists... Power consumption will solve all issues :)
Anyhow scaling works on all platforms and often depending on game.

I’m guessing this is the very same Nerdhard from WCCFkek…MetalScythe - Sunday, April 9, 2023 - link
Anandtech really should update the games they use to benchmark…MetalScythe - Sunday, April 9, 2023 - link
Going by this review, and the unexplained blatantly elderly games used to review the CPU; you would think it’s an absolute dog at gaming.Reality couldn’t be farther from the truth. This site has fallen so far from relevance… it’s saddening.
