The top Ryzen Threadripper Pro 7000WX model tested in Geekbench 5
AMD’s Zen 4 processors achieved performance leadership in servers with the 96-core Epyc 9004 “Genoa” (and the 128-core cloud version “Bergamo”). Now this technology is branching into high-end desktop and workstations. The release of Ryzen Threadripper processors with Zen 4 architecture is probably closing in, as a production sample has leaked in the Geekbench benchmark – and it’s the highest SKU that will lead the whole line-up.
An entry for what is apparently the highest model in the series – Ryzen Threadripper Pro 7995WX – has appeared in the Geekbench browser database. In the last generation, this designation referred to the top model with all cores active, and the same is true here – it’s a CPU with 96 Zen 4 cores and 192 threads. So it uses twelve 5nm CPU core dies with Zen 4 cores. This is also detected by Geekbench, according to which the CPU contains 12×32MB of L3 cache (384MB in total).
Geekbench doesn’t detect the base clock speed correctly – it’s listed at an unrealistic 7.97 GHz. Assuming this isn’t an outright hallucination, it could perhaps mean that the CPU has a base clock of 2.0 GHz and it’s being missdetected as quadruplet. This could in theory be somehow caused by the fact that the various Zen lineage cores implement clock speed selection with 25MHz granularity (0.25× multiplier steps) instead of the 100MHz increments (1.0× multiplier steps) usual with other CPUs.
The maximum boost is being detected however. According to the detailed benchmark log the core was running at a fixed clock speed of 5.15 GHz (or maybe 5.20 GHz, because in the operating system the detected clock speed always looks a bit lower and here it was around 5140 MHz). This is not necessarily the absolute peak, as we don’t know if the board and BIOS very correctly set up. For example, if the the preferred cores feature wasn’t correctly used, the processor would peak lower than its official maximum boost in the benchmark, obscuring the real specification.
Threadripper Pro CPUs will almost certainly have somewhat lower clock speeds than consumer Ryzen 7000 processors for the AM5 platform that top out officially at 5.7 GHz (unofficially at 5.85 GHz). But we can see they’ll manage to go a chunk above the 5.0 GHz bar, which will be beneficial for single-threaded performance. Although buyers will usually pick the the 96-core SKU for its multi-threaded performance, healthy single-threaded performance is also important.
World record broken?
Geekbench 5.5.1 measured 2095 points for the Threadripper Pro 7995WX in the single-threaded test (these results were taken on the Linux platform). The multi-threaded score is 81,408 points. This would actually give Threadripper Pro 7995WX’s an absolute performance leadership position. In HWBOT charts, the current record is now 72,786 points achieved with the 56-core Xeon w9 3495X (Sapphire Rapids on the W790 platform) while overclocked to 5.3 GHz with liquid nitrogen cooling.
According to the database, the benchmark of the upcoming Threadripper Pro with Zen 4 cores was done on an HP workstation (labelled HP Z6 G5 A) with a custom HP motherboard. So this was not a test run with AMD’s development platform and the device used might even be close to production already. This could indicate that the launch of Threadripper Pro 7000WX processors is not that far away. We can safely say they will appear at least in these workstation PCs from HP, but will probably be offered by other manufacturers like Lenovo, too. What will probably be most important for us is the retail availability of the standalone CPUs and boards though, which we don’t know anything about yet.
All the leaks so far have featured the Threadripper Pro processors, which are a more expensive line-up that will replace today’s WRX8 platform. But according to previous reports, AMD could once more release a more affordable “non-Pro” alternative this time around, that would be a successor to the TRX40 platform and the original more affordable Threadripper CPUs of the X399 platform. However, it’s quite possible that these will only come out at some later time after the Threadripper Pro SKUs.
