CPU Benchmark Performance: Simulation
Simulation and Science have a lot of overlap in the benchmarking world. The benchmarks that fall under Science have a distinct use for the data they output – in our Simulation section, these act more like synthetics but at some level are still trying to simulate a given environment.
In the encrypt/decrypt scenario, how data is transferred and by what mechanism is pertinent to on-the-fly encryption of sensitive data - a process by which more modern devices are leaning to for software security.
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.
Simulation
In the testing of our Dwarf Fortress benchmark, AMD's PPM and 3D V-Cache Optimizer drivers failed to detect that the Ryzen 9 7950X3D was running a gaming-focused simulation. However, the Ryzen 7 7800X3D with only one CCD was able to deliver outstanding performance in this benchmark. Similarly, in our Factorio benchmark, the Ryzen 7 7800X3D dominated and surpassed the previous Ryzen 7 5800X3D chip, as expected.
While the Ryzen 7 7800X3D did exhibit some limitations in other simulation-based tests, it's worth noting that this CPU was primarily designed for gaming and not for content creation. Therefore, we can excuse its lack of compute power in these tests. This is similar to what we observed in our Ryzen 7 5800X3D review when compared to its competitors.

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.
