AMD EPYC 7773X spotted
AMD is expected to launch its EPYC 7003 series processors with 3D V-Cache by the end of the year, but a major retailer recently listed one of the CPUs on its website and even published its prices last Thursday. Of course, like all server processors, the flagship 64-core EPYC 7773X isn't meant to be cheap, but, of course, the additional cache comes at a price.Credit: AMD This week, Zones, a important B2B retailer, has inserted on its website the AMD EPYC 7773X processor with the OPN code 100-000000504. Unfortunately, the company hasn't revealed when the CPU will be available, but apparently $ 10,746.99 will need to be shelled out for it. For comparison, the same company sells the AMD EPYC 7763, also with 64 cores, for $ 9,424.99, as also reported by @momomo_us. While we do not know the exact frequency and other specifications of the EPYC 7773X, it is evident that the additional 3D V-Cache has its price and it also seems quite high. Of course, keep in mind that it is difficult to say how accurate the cost of a product is several months after its actual marketing, so at the moment just consider it as a rumor.
Credit: Zones.com AMD's “Milan-X” EPYC and some upcoming Ryzen processors use a hybrid bonding technique (based on TSMC's SoIC process) to fuse an additional 7nm SRAM cache chiplet on top of the compute die with the direct copper-to-copper dielectric bonding of the TSVs connecting the two dies. In the case of Ryzen, AMD places 64MB SRAM chiplets on top of each processor die to significantly increase CPU L3 cache capacity and performance in memory bandwidth-sensitive workloads. We have no idea of the exact plans of 3D V-Cache for EPYC, but even 64MB of additional L3 cache improves the performance of a Ryzen 9 5900X in video games by about 15%, thus recording a significant increase in performance previously obtainable largely only. from microarchitecture level innovations. Many server workloads are bandwidth sensitive; therefore, there will be customers willing to pay extra for an additional L3 cache.
AMD's “Milan-X” EPYC family is expected to include at least four models: the flagship 64-core EPYC 7773X, the 32-core EPYC 7573X, 24-core EPYC 7473X and 16-core EPYC 7373X.
