AMD Zen 5 Server CPU Rumors: Turin With Up To 128 Cores, Turin-X With Up To 1.5 GB L3 Cache, Turin Dense With 192 Zen 5C Cores

wccftech.com:

In addition to the Ryzen 8000 leak, information regarding AMD's Zen 5 & Zen 5C powered EPYC Turin, Turin-X & Turin-Dense CPUs have been revealed too.

Once again, these new rumors come from Moore's Law is Dead latest roadmap which points out the next-generation EPYC CPU families. The roadmap covers at least five EPYC CPU lineups which can be expected in 2024-2025. AMD has already confirmed Turin as its next-gen EPYC family and it will utilize both Zen 5 and Zen 5C cores,

AMD EPYC Turin & Turn-X With Zen 5: Up To 128 Cores, 4nm Process

Starting with the first family, we have the AMD EPYC Turin (Classic) which will stick with the chiplet design and house up to 128 cores, 256 threads, and TDPs of up to 500W which can be configurable on certain SKUs up to 600W (as revealed in today's Gigabyte leak). In a previous leak, it was shown that the EPYC Turin chips would feature the same L2 and L3 cache as Zen 4 with a small upgrade to the L1 cache.

The major change will come in how AMD arranges the cache on Zen 5 chips which are expected to utilize a "Ladder" hierarchy. The chips are shown to enter production by Q1 2024 & will utilize the TSMC 4nm process node. The actual launch is expected to take place by the third quarter of 2023.

Moving on, we have the AMD EPYC Turin-X chips which will be outfitted with a 3D V-Cache. These chips will retain the 64MB of 3D V-Cache per CCD which totals 1024 MB across the 16 CCDs & 512 MB of standard L3 cache. Totaling up to 1536 MB or 1.5 GB of L3 cache. If we combine the L2 cache which is 1 MB per core or 128 MB in total, that increases to 1664 MB of total cache which is still not including the L1 cache. That's a 33% higher cache compared to the upcoming Genoa-X CPU family.
