Zen 4 s V-cache is currently said to be practically ready and AMD partners have been informed that they will receive samples in September Genoa-Xi.e. Epycs with cores Zen 4 and V-cache. This is quite possible, as according to AMD’s earlier statement, these partners should have shown more enthusiasm for AMD’s roadmap after being handed Milan-X than from the standard one Milanso the development of V-cache was apparently given a high priority.
The result is that Raphael-Xi.e. Ryzen 7000 X3D for desktop, is to be released in the first quarter of 2023 – perhaps in February-March (i.e. in half a year) and Milan-X, i.e. Epyc 9003 “X3D” for servers in the second. Let us remind you that Epyc is also planned for the first half of 2023 Bergamoa 128-core solution with compact cores It was 4c.
Notebooks: Dragon Range
In addition, he is also preparing Dragon Range, a chiplet processor for powerful notebooks, but its release date is still unclear (perhaps CES 2023 with availability at the turn of winter and spring). He will be competition not only for Raptor Lake-Pbut in the second half of 2023 it could also cost compared to mobile Meteor Lake-Pwhich will be equipped with 6 large cores Redwood Cove (~15% IPC intergenerationally?) and eight small ones Crestmont with possibly a higher intergenerational shift. Nevertheless, in such a case, it will be a battle of 6+8 cores against up to 16(+0), where the higher IPC of the six large cores of the first solution will be balanced by the higher IPC of the remaining cores of the second solution and two extra cores.
After all, this was already indicated by AMD when it published its mobile roadmap for 2023, where it states: “The most cores, threads and cache for a gaming mobile processor”. However, if in the second half of next year from Meteor Lake-P she felt unsure, she can also prepare a version with V-cache. However, such a product is not expected for the time being.
So AMD will release the Ryzen 7000 in September, then Intel’s reaction in the form is expected Raptor Lake in October. No matter how it turns out, AMD will have room for a presentation at the end of the year Raphael-X in a “but we’ve got something better” style, with a possible introduction at CES in January. The release of mobile processors may turn out similarly a few months later, where AMD may respond to Intel’s offer with a sixteen-core Dragon Range regardless of when Intel manages to release mobile Meteor Lake-P.
However, there is one major difference here compared to the desktop. While in desktop computers Intel can obtain power at 350W Extreme Performance Mode or send to the world samples with the power limit turned off, which produce beautiful scores in benchmarks, but at 420W consumption, in the case of mobile processors (enclosed in a chassis that does not even fit a water , not even a two-kilogram copper tower, let alone a funnel for liquid nitrogen) it is not possible. In such a situation, the PL2 limit of a 35-45-55-65W processor cannot exceed ~200 watts. 157 watts for the current mobile Core i9-12900HX is not enough. The situation in notebooks can therefore be a much tougher nut for Intel than in desktops, where there is nothing easier than to increase the PL2 limit by 100 watts compared to the previous generation, and another 10-15% of the performance is available.
