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.

Whoa, 428 watts at peak for the i9-14900K? I have not paid close attention to the last few rounds of releases and I knew it was bad but wholly crap. WTF Intel?jrbales@outlook.com - Monday, January 29, 2024 - link
Yeah, they definitely get pretty toasty, of it's imperative to plan out a cooling strategy to keep the CPU and other components from roasting. Of course, it does allow you to use it as a space heater in addition to a computer in cold weather. The highest TDP Ryzen 7000 CPUs run "cool" by comparison.goatfajitas - Monday, January 29, 2024 - link
Yes, it would make a good "Winter PC" LOLshabby - Monday, January 29, 2024 - link
Are they available in russia? They need them desperately to heat their frozen homes 😂GeoffreyA - Tuesday, January 30, 2024 - link
Maybe the US should donate a few out of the kindness of their hearts.ricebunny - Monday, January 29, 2024 - link
Peak power is an irrelevant metric. It’s more of a motherboard feature than anything else - Intel’s Raptor Lake will pull as much power as you give them.For those who are concerned about power, there is a TDP ceiling feature. Once set, the Intel CPU will adhere closely to the limit. Laptop tests have shown the Intel Raptor Lake to be about as power efficient as the Zen 4. Take a look at Ars’s review of Framework 13.

It is not irrenevant and is not a mobo feature. It is how much power is drawn under heavy load. When under heavy load for short bursts it can be fine, but under sustained load, it will get too hot and therefore not operate at or near turbo, it will run closer to the base clock, which is lame.TheinsanegamerN - Tuesday, January 30, 2024 - link
You are ignorant. A 14900k will shovel gobs of power if you let it. Set it to a 250 watt TDP and it will stick to 250 watt while losing MAYBE 2% peak performance.Turbo isnt SUPPOSED to be sustained, that's a MOBO feature. Have you tried reading?

Dont be so pedantic... I didnt say it was supposed to sustain it, I am saying the power draw is too damn high period. Intel is compensating for inefficient design and has been doing it since they got stuck on 14nm several years back.Are you trying to claim Intel doesnt have issues with heat here or just being pissy?

He's not being pedantic. Not in the slightest.If you can dissipate hundreds of watts of heat there is no issue. If you let the chip run uncapped and it draws lots of power... who cares... if you're willing to pay the electrical bill, I'm sure you're very happy to have that last few percent of performance.
