CPU Performance, Short Form

To show the performance and scaling of DDR5 memory, we've opted for a more selective and short-form selection of benchmarks from our test suite.

Compression – WinRAR 5.90: link

Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2867 files across 320 folders totaling 1.52 GB in size – 95% of these files are small typical website files, and the rest (90% of the size) are small 30-second 720p videos.

In our WinRAR 5.90 benchmark, this is where we saw the most effective and conclusive levels of performance, From DDR5-4800 CL36 to DDR5-6400 CL36, we saw an impressive 14.1 % increase in throughput. Even at the DDR5-6000 CL36 XMP, there was a 9.4% jump in performance in terms of scale from the baseline.

The DDR5-4800 CL32 also provided a good uplift in performance here. It should also be noted that WinRAR 5.90 performance can be very memory dependant, and it shows in our results.

Rendering - Blender 2.79b: 3D Creation Suite

A high-profile rendering tool, Blender is open-source allowing for massive amounts of configurability, and is used by a number of high-profile animation studios worldwide. The organization recently released a Blender benchmark package, a couple of weeks after we had narrowed our Blender test for our new suite, however their test can take over an hour. For our results, we run one of the sub-tests in that suite through the command line - a standard ‘bmw27’ scene in CPU only mode, and measure the time to complete the render.

In terms of scaling performance in our Blender benchmark, we saw very little variation in performance from top to bottom. Although the Trident Z5 at DDR5-6400 CL36 did perform best, it was a modest 0.6% jump in performance from our lowest result to the best.

Rendering - Cinebench R23: link

Maxon's real-world and cross-platform Cinebench test suite has been a staple in benchmarking and rendering performance for many years. Its latest installment is the R23 version, which is based on its latest 23 code which uses updated compilers. It acts as a real-world system benchmark that incorporates common tasks and rendering workloads as opposed to less diverse benchmarks which only take measurements based on certain CPU functions. Cinebench R23 can also measure both single-threaded and multi-threaded performance.

Looking at performance in Cinebench R23, the results were a little sporadic, in both the single-threaded and multi-threaded testing. All of the results in the single-threaded test were within a margin of 1.8%, with the multi-threaded results within a 1.6% level of variation from top to bottom.

3DPMv2.1 – 3D Movement Algorithm Test: link

3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz, and IPC win in the single thread version, whereas the multithread version has to handle the threads and loves more cores. For a brief explanation of the platform agnostic coding behind this benchmark, see my forum post here.

Similar to what we saw in both Cinebench R23 and in our Blender benchmarks, performance in our 3DPM v2.1 testing shows little to no improvement with faster memory across the range of results. The level of variation between the best result and the worst result was around 0.3%.

    That's DDR4 vs GDDR5, not DDR4 vs DDR5. GDDR is dual ported and can be read from and written to at the same time.

    Do you have a source for that for those of us who don't want to take your word? Also this article is about ddr5 memory scaling so I don't know why they half assed the article and didn't do iGPU testing.

    I do not understand how in the gaming tests of a top-of-the-range processor and last generation memory combined with a GPU almost 5 years old and 4K and 1440 resolutions, that analysis is really meaningless, they have a terrible bottleneck.
  • HammerStrike - Thursday, December 23, 2021 - link

    Yeah, it’s bafflingly. I get the GPU shortage situation is an issue (although you can buy GPU’s, just at inflated prices, not to mention the industry contacts they have), but to test at 1440p / 4k at high settings on a 1080 is just… ignorant?

    Worse case if you are stuck with the 1080 test at 720p low settings to make the CPU and RAM as much a bottle neck as possible. What they did is just a waste of time.

    Ever tried going to a GPU vendor, asking for 2-4+ of the same high-end GPUs (for concurrent testing), during a shortage, saying you can't promise them a review, just for testing? Even with the CPU stuff, it happens once every two generations, maybe, so trying to get one for our motherboard guy is nearly impossible. No we don't have the budget. People complain that I'm running RTX 2080 Ti cards on my CPU reviews. Either we run what we have and the article is written in that context, as mentioned right there on page one no less, or we don't run anything at all.
  • andr_gin - Thursday, December 23, 2021 - link

    I understand your problem about not having high end GPUs, but why not at least reduce resolution to 720p?
  • Ryan Smith - Thursday, December 23, 2021 - link

    That's an unforced error on our part. We're going to run the numbers for 720p and update the article. Thank you for the feedback.

    More important is DDR-4 data for comparison, particularly at low latencies and nothing below 3200 speed.
  • shabby - Saturday, December 25, 2021 - link

    I find it hard to believe you can't source a video card, no other reviewers have this issue and I bought two myself this year.

    1) Go to Oxford for transistor studies
    2) See moron youtubers become millionaires running canned benchmarks
    3) Still refuse to leave Anandtech
