AMD Ryzen 9 PRO 9965X3D appears on PassMark with similar performance to the Ryzen 9 9950X3D

An unreleased Ryzen PRO series processor has just been spotted on PassMark, but the interesting bit is that it is an X3D CPU with 3D V-Cache. AMD's Ryzen PRO lineup is targeted towards professionals, content creators, and other productivity-focused users. There have been rumors of an X3D Ryzen PRO chip out in the wild before, but it has never been benchmarked as it has now.

The new CPU that has just been added to PassMark's database is the AMD Ryzen 9 PRO 9965X3D. We have a couple of interesting things to note about the nomenclature first. First, the XX65 number has not yet been used in the Ryzen 9000 PRO series lineup, and second, the CPU has 3D V-Cache, a feature typically targeted at gamers.

Looking at the information on PassMark, the "new" 9965X3D is a 16-core, 32-thread processor just like the consumer Ryzen 9 9950X3D. The unreleased PRO chip is the first 16-core CPU in the lineup, and it slots in right above the Ryzen 9 PRO 9945, a 12-core, 24-thread Zen 5 CPU. On the page, the L3 cache is listed as 32MB, but that seems incorrect, as it doesn't align with other 3D V-Cache CPUs.

Another interesting bit is the performance, which is represented by single-threaded and multi-threaded ratings on the site. The Ryzen PRO 9965X3D scores 4614 points in single-threaded tasks, while the multi-core rating is 65111. For context, that is about 2.7% slower than the consumer Ryzen 9 9950X3D in single-thread, and 7.3% slower in multi-threaded tests.

It should be noted that Ryzen PRO chips have a lower TDP, so the performance difference is to be expected. In line with other PRO chips, the 9965X3D might have a 65W TDP, compared to the 170W of the 9950X3D. Moreover, there are currently only three samples of the 9965X3D on the site, so the score is likely to become more accurate once more results are submitted.

Currently, AMD's Ryzen PRO 9000 series desktop lineup is led by the 12-core Ryzen 9 PRO 9945, followed by the 8-core Ryzen 7 PRO 9745, and the 6-core Ryzen 5 PRO 9645. Given the information available, the Ryzen 9 PRO 9965X3D is bound to be the flagship CPU of that particular lineup; however, curiously, there is no sign of the standard non-X3D Ryzen 9 PRO 9965 as of right now.

It will also be interesting to see why AMD chose to give 3D V-Cache to a PRO series CPU aimed at OEM workstations and productivity use.
