Fresh AMD Zen 5 CPU details leak suggesting a likely launch date between April and June of this year

Further details are beginning to leak for AMD's next generation of desktop processors built on the Zen 5 architecture. These new «Granite Ridge» CPUs are currently expected for release in the first half of this year, and we're now starting to see information that looks to add some credence to the earlier rumours referencing the new chips.

These most recent leaks come from a tweet from known AMD leaker <a data-analytics-id=«inline-link» href=«https://twitter.com/highyieldYT/status/1749840914653098205?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Etweet» target="_blank" data-url=«https://twitter.com/highyieldYT/status/1749840914653098205?ref_src=» https:>High Yield YT

(via TechPowerUp), and seem to give weight to some of the previously rumoured details that have already been doing the rounds for AMD's next desktop CPUs. AMD will reportedly be using the Ryzen 9000 series model numbering scheme, which was to be expected as the 8000 series moniker is already being used for the new AM5 APUs based on «Hawk Point».

Granite Ridge is said be a chiplet-based processor like the previous 7000 series, and is expected to feature one or two «Eldora» CCDs, each containing eight Zen 5 CPU cores, each with 1 MB of L2 cache, with no word yet on how much L3 cache we're likely to see.

The chips are said to be built on TSMC's 4nm process, with similar clock speeds to the existing generation and a predicted double-digit uplift in performance, which would align with similar predicted performance figures from Moore's Law is Dead, who predicted between 10-15% IPC gains in September of last year. 

This would put the new CPUs on a performance level similar to the current generation of Ryzen 7000X3D processors without the use of 3D cache. Those gains would track with the previous uplift in performance between the Zen 3 and Zen 4 series of AMD CPUs, with the 7000 series chips running on average 13% faster than the previous generation.

The new chips are quoted as retaining the same I/O die as the
