AMD Zen 4 Based Ryzen CPUs May Feature Up to 24 Cores, Support for AVX512 Vectors

There has been fairly limited talk of AMD’s Zen 4 processors as of late. Now, @hxl (a pretty reliable source) has broken the silence by stating that the consumer-grade Ryzen CPUs based on Zen 4 and TSMC’s N5 (5nm EUV) process will feature up to 24 cores. Considering that is the first node shrink in over two generations, this isn’t all hard to believe. Furthermore, since Zen 2 in 2019, we haven’t seen the core count of AMD’s consumer processors increase. Although 16 is still more than sufficient for most users, Intel is expected to increase the core count of its desktop parts to 16 cores with Alder Lake-S (8 Golden Cove + 8 Gracemont).

If Gracemont is indeed comparable to low-power Skylake cores, then this may greatly close the gap between AMD and Intel’s top-end offerings. At present, the latter’s fastest chip, the Core i9-11900K is simply incomparable to the Ryzen 9 5950X in terms of multi-threaded performance. As such, if Intel is working on a 16-core part, AMD too might be looking to extend its multi-core lead.

While it’s not confirmed whether we’re going to see a 24-core part, we’ll most certainly see a 20-core or 18-core offering, with different combinations of cores on the 8-core CCDs disabled. A 24-core part may not come to fruition as you’re essentially looking at three defect-free dies, something that may not be viable depending on the prices of TSMC’s 5nm wafers.

The second part is with respect to AVX512 or AVX3 support on Zen 4. It’s unlikely it’ll come to the consumer-grade Ryzen CPUs, but we might see them in the Epyc Genoa server processors. This would mean that we’re either looking at two FP256 EUs being combined in the latter or something completely opposite in the former. (buy ambien online from canada) Either way, AVX512 is largely irrelevant in the consumer market for the time being.

The last bit is regarding Warhol. It turns out that the Zen 3+ lineup may not have been completely scrapped, and may take the form of the Ryzen 5000 XT parts. Considering that the 600-series chipsets are going to come to AM5, this is the most likely scenario. Furthermore, it’s unclear whether Warhol will leverage the N7, N7P, or the N6 process, all of which are derivatives of the 7nm node.
