First evidence in the form of screenshots from a system built on a pair of 64-core Epyc samples Turin with cores Zen 5 appeared already in mid-April. Now the photos posted by the leaker YuuKi_AnS also follow. Samples Turin is not significantly different from the existing Epyc Genoa.

However, the difference will be under the lid (IHS), which covers (outside the central chiplet) either sixteen eight-core chiplets with cores Zen 5or in the case of Turin-dense twelve sixteen-core Zen 5c chiplets.

The total number of cores increases by 32-64, i.e. by 33-50%.

The diagram also shows that the central chiplet (IOD) will speed up memory support from the current DDR5-4800 to DDR5-6000, i.e. by 25%.
AMD originally planned to release first Turin-dense with cores Zen 5c (and TSMC’s 3nm process), but eventually reversed the order and plans to start with the classic version first Turin (Zen 5 on TSMC’s 4nm process). It could be released sometime in the third quarter. The dense variant then sometime in the winter of 2024 / 2025.
