In the Geekbench, the Ryzen 9 7950X3D cannot claim a significant point bonus compared to the model without a V-cache. That doesn’t come as a complete surprise. Added value is only expected in games and applications that have the cache.
The Ryzen 9 7950X3D should cost 800 euros – at least in the preliminary listing of a French dealer. Benchmarks have now also appeared for the model – albeit initially only in Geekbench. And it quickly becomes clear that the Ryzen 9 7950X3D cannot use the 144 MiByte cache (64 MiB of which as V-cache). With 2,157 points in the single-core and 21,841 points in the multi-core result, the Ryzen 9 7950X3D is on par with the Ryzen 9 7950X. Two and five percent separate the models.
This isn’t entirely surprising as the Ryzen 9 7950X3D will be more likely to show off the cache in games and applications that benefit from the larger cache. You already know that from the Ryzen 7 5800X and its 3D companion. The good news is that, despite the cache, only a few percent make the difference. They could even melt away if the test environments are better coordinated.
AMD says the Ryzen 9 7950X3D can beat the Core i9-13900K in games. In applications it should run even better. On the productivity side, AMD promises a performance increase of sometimes more than 50 percent.
The Ryzen 9 7950X3D and 7900X3D will go on sale on February 28th, followed by the Ryzen 7 7800X3D on April 6th. The three processors come with a significantly higher array of L3 cache than their counterparts from September last year thanks to 3D V-Cache, although AMD did not release a Ryzen 7 7800X at the start of the Ryzen 7000 and Zen 4. What is new for the large models is the heterogeneous design, in which the cache sits on a CDD. The success of the heterogeneous design will also depend on how well or not Microsoft will adapt the Windows scheduler and how far this will be possible. In theory, the goal is that tasks that benefit from cache are moved to the CCD with V-cache and tasks that benefit from the clock are assigned to the CCD without V-cache. This is not relevant for the Ryzen 7 7800X3D as it only has one CCD. According to the website of a French retailer, the 7950X3D is scheduled to be delivered on March 16th, so it seems that the retailer has no stock on release day.
