CPU Benchmark Performance: Science And Simulation
Our Science section covers all the tests that typically resemble more scientific-based workloads and instruction sets. 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.
Adding to our 2024 CPU suite, we've included the Montage Astronomical Image Mosaic Engine (MAIM) benchmark and OpenFOAM 1.2 and retained our gaming simulation benchmarks, including our Dwarf Fortress and Factorio benchmarks.
We are using DDR5-5200 memory as per the JEDEC specifications on the Ryzen 7 8700G and Ryzen 5 8600G, as well as DDR4-3200 on the Ryzen 7 5700G and Ryzen 5 5600G. The same methodology is also used for the AMD Ryzen 7000 series and Intel's 14th, 13th, and 12th Gen processors. Below are the settings we have used for each platform:
- DDR5-5200 CL44 - Ryzen 8000G
- DDR4-3200 CL22 - Ryzen 5000G
- DDR5-5600B CL46 - Intel 14th & 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
In our simulated and science-focused tests, much of the same happens here as we saw in encoding and rendering; bigger cores and more of them make the difference. We did see strong AVX performance, which is a given since Zen 4 supports AVX-512 workloads via two 256-bit channels. We also saw solid performance in y-Cruncher, with the Ryzen 5 8600G beating out the Ryzen 9 7900 in single-threaded performance. This shows that despite using more power-efficient Phoenix dies, Zen 4 on mobile still offers solid single-threaded performance when transitioned over to the desktop.
Testing without STAPM limitations in our Science and Simulation benchmarks and removing the sustained power management limits didn't really make much difference in performance in these tests.

On another point, I still think Anand's CPU reviews were better than Ian's. Ian was good but tended to get lost in the details, whereas Anand had an abstraction to his writing, and made computers inspiring, as if you were reading a story. Even the titles were memorable.TheinsanegamerN - Wednesday, January 31, 2024 - link
If you are going by steam, there are nearly as many sub 1080p as there are 1080p gamers. And those sub 1080p users would love the iGPU.If you dont like it, feel free not to read it. Or do your own review if you are so much smarter.

Gamers Nexus has found an Issue with the Ryzen 8000G APUs in the form of some Mobile Variants of the 7000/Phoenix mobile processor firmware settings that should have been removed for the Desktop Ryzen 8000G series Phoenix derivatives. And that has something to do with Laptop/Handheld skin temperature regulation where in order to account for that in laptops/handhelds the processors are being trotted in the Desktop Ryzen 8000G SKUs as if that's in a mobile laptop/handheld from factor device! So watch GN's latest video from today and see that more re-testing may be in order there!nandnandnand - Tuesday, January 30, 2024 - link
It's Skin Temperature Aware Power Management (STAPM).Kinematics - Tuesday, January 30, 2024 - link
The 88 W peak draw is about 25 W above the 65 W TDP, not 35.mikato - Tuesday, January 30, 2024 - link
Are we not doing idle power consumption any more?t.s - Tuesday, January 30, 2024 - link
This depend significantly from PSU and motherboard you're using. anything x70 chipset 24ATX PSU will boost the idle power vs when using x20 and 12VO. But yes, I'm curious too with their setup idle power. My guess, around 50W -> 24ATX 1000W, 6950 GPU.mannen - Tuesday, January 30, 2024 - link
You missed to compare these against the Ryzen 5 7600 and the Ryzen 7 7700 CPUs.That would have been very interesting since they are equivalent (but desktop) parts with the same number of cores/threads. To compare to Ryzen 9 makes no sense since it's not within the same budget class.
I for example am interested in the 8600G, but also looking at the 7600 and keeping my old GPU. Since I don't game a lot, I can easily sacrifice the old GPU but I want to know how much CPU performance I'm giving up.

Well the other commenters here are throwing huge temper tantrums over CPU benchmarks being included in this review, so you may be better off looking elsewhere.lorribot - Tuesday, January 30, 2024 - link
Would have been nice to see a comparison with discrete cards like a RTX2060/3060.
