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 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.

(2-5f) SciMark 2.0: Jacobi Successive Over-Relaxation

(2-6) Primesieve 1.9.0: High Core Count

Our science-focused benchmarks highlight the fact the Core i9-13900KS and Core i9-13900K are both very similar in regard to performance. Outside of the 3DPM v2.1 AVX test where AMD gains the advantage in actually supporting AVX-512 instruction sets, the additional bump to base and turbo clock speeds doesn't yield too much benefit here.

    Practically useless, even at 720p. Looking forward to 7000X3D.

    Sure, the i9-13900KS can be seen as "the best"...
    ...but it's hard to justify it for the real-world when there's the Intel Core i5-13600k right there! You're paying half the amount and using less power, to achieve a very impressive score right up there with the best.

    I guess even more impressive is the AMD r7-7700 which trades blows with that chipset in performance, competitively price, uses significantly less power, and most importantly has a long support (AM5) period.

    I wish we continue to see this trend, with the luxury products making it clear to show how good the mid-high range products have become. In some parts this is a correction in the market due to new competition. Consumers rejoice!

    A very expensive and fast cpu is testet with some very slow memory. I don’t see the point in doing that. The slowest memory rated as DDR5-5600 in my local webshop is CL40 and the most commen is CL36 and I could choose CL28. CL46 is not an option. I’m not in the market for this cpu, but if I were I would combine it with DDR5-7200 at CL32. If memory overclocking is not an option, then I would use DDR5-5600 CL36.

    Have to agree with you on this. No one buying this CPU is going to be pairing with the DDR5-5600 memory.

    I forgot to add, that apart from my minor critics regarding choice of memory, that it is nice that AnandTech makes these thorough reviews. I don’t think I can find such quality reviews anywhere else for pc-class hardware.
  • Great_Scott - Wednesday, February 1, 2023 - link

    The reviews are great, although I can't imagine there's a single hand-built Ryzen PC in existence that's using memory at JEDEC timings.

    It was interesting to see how the Ryzen 7950X was able to keep up in a large number of tests.

    Honestly, I wish these high end CPUs were tested at the speeds they can run 128GB of RAM at. From what I've seen around the web, these tested RAM speeds are higher than either can manage reliably when all 4 dimms are filled.
  • jospoortvliet - Monday, February 13, 2023 - link

    Well Andresen thinks it should be faster you think slower. I guess they did it right?

    "*We changed the motherboard to the GIGABYTE Z690 Aorus Master as the MSI MPG Z790 Carbon WIFI we used for our previous 13th Gen Core series reviews refused to play ball. We don't like to make these changes lightly, but we weren't able to source another Carbon in time for this review"

    Did it fail outright, or still work for other chips but choke on this extra-power hungry one?
