The AMD Ryzen 9 7900, Ryzen 7 7700, and Ryzen 5 7600 Review: Zen 4 Efficiency at 65 Watts

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 12th and 13th Gen Core parts, as well as the Ryzen 7000 series, at 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
Given that all of AMD's Ryzen 7000 series line-up includes AVX-512 support, it stretches above the non-AVX-512 enabled chips in our 3DPM v2.1 AVX benchmark. Looking at the general consensus in our other tests where multi-threaded performance is essential, all three 65 W Ryzen 7000 SKUs perform well considering their lower power limits, but it does underscore why AMD (and Intel) have higher TDP chips as well.

How do you get V-Ray benchmark values which are 35 to 50% higher than anything that can be seen on the results page?What version of the benchmark are you using?

Ummm....don't think he ever did the testing update he said he would try to do (but was busy) the weekened after the article came out?Gavin Bonshor - Monday, February 6, 2023 - link
It's coming, don't worry.Gavin Bonshor - Monday, February 6, 2023 - link
It isn't the latest iteration. It's the previous version (4). The critical area to consider is the consistency of the results within the same version.Of course, we will update this benchmark in our next wave to the latest version. If we did this for every benchmark, I would spend 100% of my time testing and 0% writing.

I'd like to know the idle power consumption of the CPUs. Apparently there is quite a difference at idle between the latest AMD and Intel options but can't seem to find much in the way of tests.
