In accordance with a Tweet by semiconductor engineering skilled Tom Wassick, (opens in new tab) it seems that Ryzen 7000 processors seemingly acquired some upgrades in preparation for upcoming SKUs with 3D V-Cache. Wassick has reportedly found extra TSV columns within the Zen 4 CCD, suggesting this improve may enable for higher V-Cache bandwidth potential than the Ryzen 7 5800X3D, one of many greatest CPUs for gaming.
To be extra particular, Wassick says there are two a lot bigger and denser arrays on the Ryzen 7000 chip and a few pitch discount – together with the extra TSV columns. It means Ryzen 7000 3D V-Cache slabs could have extra contact space with the CPU, resulting in higher L3 cache bandwidth and doable additional energy.
3D V-Cache is AMD’s stacked L3 caching know-how that permits the chipmaker to triple the quantity of L3 cache out there to the chip by stacking an extra 64MB of SRAM cache on prime of a Ryzen’s CCD—considerably boosting L3 cache-sensitive workloads equivalent to gaming.
The one consumer-based chip that AMD has launched with 3D V-Cache know-how is the Ryzen 7 5800X3D, which options 96MB of L3 cache in complete. The Ryzen 7 5800X3D exploded to the highest of our gaming charts, the place it may match or outpace the competitors, equivalent to Intel’s twelfth Technology Alder Lake CPUs.
For Ryzen 7000, the extra TSV contacts counsel AMD’s second-generation implementation of the stacked cache could have greater bandwidth potential over the Ryzen 7 5800X3D’s already spectacular 2 TBps bandwidth. Nevertheless, as a result of comparatively small measurement of the L3 cache, in comparison with DDR4/DDR5 reminiscence, having extra bandwidth is all the time beautiful to have, so the CPU can swap sources out and in of the L3 cache at a sooner fee, which may enhance efficiency.
We suspect the extra contact factors will even give the 3D V-Cache different energy enter if obligatory. Further energy may additionally present the V-Cache a extra appreciable efficiency enhance, however that may rely on the design selections AMD will use for AMD’s Ryzen 7000 components; there’s an opportunity the 3D V-Cache could possibly be extra environment friendly and require much less energy as an alternative of extra energy.
General, these further TSVs do not say a lot about how AMD’s next-generation 3D V-Cache will function or how a lot better it will likely be over the 5800X3D. However there is a good likelihood it means Ryzen 7000X3D will, on the very least, have extra bandwidth over the Ryzen 7 5800X3D based mostly on this info.
