Test results:
This is the part that will interest us most, allowing us to assess the performance of this ultra-high-end configuration. As a reminder, our copy of the Xeon W9-3495X is equipped with 56 cores and 112 threads. We’ve taken our usual graphics and added the performance of this stock processor, i.e. without any overclocking.
Let’s start with a staple of processor benchmarks, the Cinebench series. We’ve opted for Cinebench R23 and R20. Scores will be given in single-core and multi-core mode. By this we mean that the benchmark tests performance on a single processor core and then on all available cores.
To do this, we’re going to use Benchmate, which has just been updated to version 10.12.2 and can be downloaded here. The advantage of Benchmate is that it already contains a whole series of benchmarks, and what’s more, it’s recognized and certified when you want to encode your results on the Hwbot site.
Cinebench multi core in R20 and R23 with the W9-3495X :
Let’s start with two Cinebench multi-core benchmarks with R20 and R23. There’s no point in running them in single core, since the 4.8 GHz frequency won’t produce interesting scores. Here, it’s the use of the 56 cores that should make the difference!
We’ve added them to our CPU test charts so you can see the performance impact. The results speak for themselves.
Geekbench multi core 3.4.4, 5.2.5 and the new 6 PRO with W9-3495X :
This is a benchmark available in several revisions, with version 5 being increasingly used in recent months and often used for CPU performance leaks. It provides two scores: one single-core and one multi-core. The versions used for testing are 3.4.4 and 5.2.5. Please note that to take full advantage of these three benchmarks, a license is required and we’re running the bench in 64-bit.
Once again, scores that crush the competition.
CPU-Z 17.01.64 multi-threaded and Y-Cruncher benchmark with the W9-3495X :
A new benchmark that we’ve just added, as it’s increasingly used by brands to showcase processor performance. To use it, simply download the latest version of CPU-Z, currently 2.0.2. Then go to the “Bench” tab to check single-thread and multi-thread performance. The benchmark version we used is 17.01.64. We also took the opportunity to test Y-cruncher.
Here too, performance is monstrous, with our Xeon W9-3495X scoring 33271 points in the multi-threaded CPU-Z benchmark and 7.707 seconds under Y-cruncher PI-1b.
AIDA 64 with the W9-3495X :
This software can provide you with a wealth of information about your configuration, but above all it features a memory benchmark. This calculates the read, write and copy speeds, as well as the latency, of your memory kit. It is often used to compare memory kits. It’s an excellent tool if you want to compare the performance of your memory kit with those we’ve already had the opportunity to test.
Here too, throughputs are impressive, particularly when using our eight GSKill memory arrays at 6400 MT/s CL 32. Last but not least, we didn’t run a 3DMark, as the scores were simply not good enough. The 3DMark benchmark suite can’t handle that many cores. As an example, we obtain a CPU Time Spy score of 10822 points with the W9-3495X, where the i9-13900KS scores 24684 points.
Overclocking the Xeon W9-3495X :
One thing’s for sure: as soon as we started overclocking, temperatures began to soar, and an excellent cooling system was needed, especially as the north is currently the south! After a great deal of research and BIOS tweaking, we managed to achieve stability at 4.2 GHz on the 56 cores of our W9-3495X.
The Cinebench R23 multi-core score rises from 71115 points to 101304 points, an increase of 42.4%. Geekbench 3.4.4 scores 303465 points, a gain of 47.1%. Temperatures are in the region of 88°C. We’re looking forward to testing a “slightly lighter” Xeon in terms of cores when overclocking. Unfortunately, we weren’t able to run it under LN2, as it requires a special fixture that only der8auer currently has.
