AMD’s Ryzen 6900HX is expected to be announced on January 4, 2022 at CES in Las Vegas, but its specs have already been leaked and some things seem particularly interesting, especially on the RAM and GPU side.
AMD Rembrandt (Ryzen 6000) processors will power laptops in 2022 and a leak tells us a bit more about the technical advancements we can expect in this regard. Our colleagues from Wccftech In fact, they have revealed some interesting information about the Ryzen 6900HX, a very high-end processor that will replace the current 5900HX in laptops.
DDR5, but without V-Cache 3D
This CPU will incorporate 8 cores (and 16 threads) based no longer on the Zen 3 architecture, but on Zen 3+. The latter is a small evolution that brings a 6nm etching process (versus 7nm currently), as well as 3D V-Cache, a vertical cache stacking technique that should provide a nice performance boost, in-game. in particular. Unfortunately, it appears that the mobile versions of the Zen 3+ CPUs will not take advantage of the 3D V-Cache and this Ryzen 6900HX will have to settle for its 16MB L3 and 4MB L2 cache.
With a clock frequency of 4.6 GHz, on the other hand it can be coupled to DDR5 RAM and take advantage of its wide bandwidth, while this is not expected for CPUs. desk only from the next architecture, Zen 4.
The integrated GPU portion of the processor can benefit from significant performance gains, as the RDNA 2 microarchitecture, found in particular on the Xbox Series and PlayStation 5 consoles, will be included under the name Radeon 680M and will replace the Vega architecture. . That said, this type of processor designed for very high-end PCs will generally be paired with dedicated graphics cards and the interest of the integrated GPU may seem limited. If the RDNA 2 architecture were to be integrated into other processors in the range, such as Ryzen 5 and 7, this could, on the other hand, be particularly interesting for ultrabooks that do not have a dedicated GPU. According to recent leaks from points of referenceWe can expect performance worthy of a GeForce GTX 1050 or Nvidia MX550, dedicated entry-level graphics cards.
We still don’t know how many GPUs these RDNA 2 chips will ship or when the Ryzen 6900HX will start powering laptops, but we should learn more very soon at the next CES in early January 2022.
