Two new AMD Ryzen X3D gaming CPUs are reportedly coming quickly, with a lot larger clock speeds than the Ryzen 7 9800X3D, which launched earlier this 12 months. In line with many rumors, the 16-core AMD Ryzen 9 9950X3D and 9900X3D are each set to be introduced in January 2025, however details about a few of the key specs has now leaked as properly.
We had been wowed by the efficiency of the most recent 3D V-cache tech in our latest AMD Ryzen 7 9800X3D overview, however its clock velocity remains to be comparatively low at 5.2GHz, even when you can overclock the 9800X3D simply sufficient. That’s apparently set to alter with the brand new AMD X3D chips, which reportedly run on the identical clock speeds as their non-X3D counterparts, however there’s a giant catch.
The catch is that it doesn’t look as if the cores kitted out with 3D V-cache in these CPUs will be capable of attain these excessive clock speeds. As a substitute, there’ll apparently be two chiplets in every CPU, one with out 3D V-cache that runs at excessive clock speeds, and one with 3D V-cache that runs at a decrease frequency.
This newest rumor comes from common tech leaker HXL (9550pro) in a publish on X (previously Twitter), in addition to some further leaks in regards to the chips in additional posts. The important thing one states “Zen5 X3D No frequency debuff,” implying that the brand new X3D chips will run on the identical clock speeds as their non-X3D siblings. If that’s true, this implies the Ryzen 9 9950X3D clock velocity is 5.7GHz, whereas the Ryzen 9 9900X3D clock velocity is 5.6GHz, when referring to most increase clocks.
That is additional bolstered by a publish during which HXL says that the single-thread (1T) and multi=threaded (nT) efficiency of the Ryzen 9 9950X3D in Cinebench R23 is near that of the Ryzen 9950X. When requested whether or not the clock velocity applies to all cores, together with these with 3D V-cache, the reply says “Frequency CCD + Cache CCD,” that means two chiplets, one with a excessive clock velocity, and one with further cache.
This rumored setup works very equally to that of AMD’s present X3D chips, which even have the additional cache on one chiplet, and better clock speeds on one other one. Nonetheless, this has created just a few points. One is that the Ryzen 9 7950X3D has six cores on every chiplet, that means that solely six of its cores have 3D V-cache, making the 7800X3D a greater CPU for gaming, as all eight of its cores can entry the additional cache. One other situation has been latency between cores – if a recreation makes use of a core on the incorrect chiplet, then it would get the next clock velocity, but it surely has to go off-chip with the intention to entry the information within the further cache on the opposite chiplet.
AMD is rumored to be taking a brand new strategy with these new X3D chips, although. Firstly, we’re hoping that the Ryzen 9 9900X3D can have one eight-core chiplet with 3D V-cache, and a second quad-core chiplet with excessive clock speeds, so it might not less than match the 9800X3D in video games.
Motherboard producers, reminiscent of Gigabyte and Asus, have additionally began introducing a brand new Turbo X3D mode, which Gigabyte says provides “efficiency will increase of as much as 18% for incoming Ryzen 9000 collection 16-core X3D processors.”
These modes are designed to regulate the way in which cores are assigned to workloads, so in a recreation, it may disable the chiplet with out 3D V-cache solely, in addition to SMT, successfully treating your CPU as a 9800X3D. In case you want extra cores, maybe for video encoding and 3D rendering, you may them change again to a traditional mode and acquire entry to all of your cores, together with ones working at excessive clock speeds.
In fact, not one of the above has been formally confirmed by AMD, so take it with a grain of salt for the second, however we’re actually hoping that AMD will get it proper with these CPUs. It seems to be as if the corporate is aiming to get the very best of each worlds in a single chip, and if it’s not going to place 3D V-cache on each chiplets, then this seems to be like the very best various.
In case you’re trying to construct a gaming PC primarily based on one in every of these new chips, then take a look at our information to the very best gaming motherboard, which has a number of Socket AM5 choices, and likewise check out our greatest gaming CPU information, the place we have a look at all the very best choices at a spread of costs.
