At the beginning of 2022, AMD will bring the last desktop processors for the AM4 platform: CPUs with attached memory chips that triple the level 3 cache per eight-core cluster from 32 to 96 MB. A newly launched Ryzen 9 5900X thus has 192 MB L3 cache. In 3D games, the frame rate should increase by 15 percent thanks to the intermediate buffer, provided that the performance of the graphics card is not limited.
AMD announced these 3D V-Cache CPUs as part of the virtual Computex 2021 and announced a start of production by the end of the year. A market launch in early 2022 is therefore not surprising. The interview date was approaching AMD’s head of technical marketing, Robert Hallock, as part of a video, which was created for the fifth birthday of Zen architecture. This formed the basis for today’s success – Ryzen 5000 uses the third Zen iteration.
Hallock also confirmed there that AMD intends to introduce new notebook combination processors in early 2022. This traditionally takes place at the electronics trade fair CES, whereupon the first corresponding devices follow weeks or months later. Rumor has it that Rembrandt is next with a combination of Zen 3 cores and RDNA2 GPU.
AMD to AM5 and hybrid computing
AMD will not have a direct answer to Intel’s 12th Core i generation Alder Lake S with 10 nanometer technology this fall without V-Cache CPUs. Alder Lake uses hybrid computing, a combination of small, efficient atom cores and larger, faster cores to improve performance and efficiency. The generation appears together with the new desktop platform LGA1700 including DDR5 RAM and PCI Express 5.0.
In this context, however, Hallock contradicts rumors that the next AM5 desktop platform will have to do without PCIe 5.0 for the time being. AM5 should master all current technologies by the end of 2022 and be compatible with previous AM4 coolers.
Speaking of hybrid computing: AMD does not plan to combine differently developed CPU cores within one processor in the next few years. According to Hallock, the Zen architecture offers “much, much more” potential for reducing power consumption and thus maintaining the crown of efficiency. For this, AMD relies on a combination of finer manufacturing processes, new packaging techniques, improved power management and more sophisticated power states for putting individual chip parts to sleep.
