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 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.

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

(2-6) Primesieve 1.9.0: High Core Count

Looking at the performance of the Ryzen 7 7800X3D in our scientific-based workload testing, we can see that the 7800X3D is comparable to its lower-powered and 3D V-Cacheless Ryzen 7 7700 sibling. As we would expect from a newer chip, we can see that the Zen 4-based Ryzen 7 7800X3D for the most part beats out the Zen 3-based Ryzen 7 5800X3D.

    It’s because Anandtech’s gaming benchmarks are using insanely outdated games.

    Do your due-diligence and read other publications’ reviews of the chip. They’re much faster at gaming than this “review” makes them seem.

    Looking at the results in this review, are we certain that there was no "core parking driver" contamination? Because the 7800X3D seems really slow where it shouldn't be.
    Gamers Nexus had this issue and had to do a clean install to get their 7800X3D to work properly and not park cores.

    Hi Meacupla, I can confirm I had no core parking driver issues, but I did use a fresh install of Windows 11 as per AMD's suggestion. I knew that issues could arise before even installing the CPU, but as I confirmed earlier, I didn't notice any odd behavior.

    Can I ask, where do you believe the 7800X3D is slow in our testing?
  • Foeketijn - Thursday, April 6, 2023 - link

    The cases where it loses from the 5800X3D maybe.
    I find it also fascinating how often the 7600x is faster. And isn't mentioned when you make the "Cheaper CPU will enable you to buy a better GPU" point.
    But that's a different story.
  • meacupla - Thursday, April 6, 2023 - link

    this part
    All the other reviews I've seen put the 7800X3D ahead by a wide margin in gaming results at 1080p and 1440p when compared against a 7600X and 7700X.
  • MetalScythe - Sunday, April 9, 2023 - link

    Again, it’s because the games Anandtech uses for game reviews are incredibly outdated.

    I mean… GTA V in 2023!??

    People need to stop bitching about memory speed. 7000 series are hard-capped at 6000 MT/s (up to 6400 MT/s with questionable stability) and regular non-3D chips barely show the impact of faster memory. For these 3D V-cache chips, faster memory is literally a waste of money. As a matter of fact I'd argue it is one of the benefits of using these chips that you can get away with budget memory.
  • roboiii - Thursday, April 27, 2023 - link

    If you do a decent amount of reading/video watching it's fairly evident that 6000 @ 30 is the "sweet spot". I think rather than "bitching" people want to see their tech sources engage in actual tech that's applicable to the part in question. x3d is a part designed & marketed to gamers, who typically have a rig with high end parts and utilize the highest memory settings to achieve better performance.

    The borked 7950x3d results are still there for Dwarf Fortress and Factorio.
  • Gavin Bonshor - Thursday, April 6, 2023 - link

    They are because they are the figures we got when running the original test suite. I did run the suite a couple of times to see where the PPM driver got things wrong, and the 7950X3D running on the 3D V-Cache enabled CCD performs as well as the 7800X3D does in Factorio and Dwarf Fortress.
