AMD Ryzen 8000 "Granite Ridge" Zen 5 Processor to Max Out at 16 Cores
AMD's next-generation Ryzen 8000 "Granite Ridge" desktop processor based on the "Zen 5" microarchitecture, will continue to top out at 16-core/32-thread as the maximum CPU core-count possible, says a report by PC Games Hardware. The processor will retain the chiplet design of the current Ryzen 7000 "Raphael" processor, with two 8-core "Zen 5" CCDs, and one I/O die. It's very likely that AMD will reuse the same 6 nm client I/O die (cIOD) as "Raphael," just the way it used the same 12 nm cIOD between Ryzen 3000 "Matisse" and Ryzen 5000 "Vermeer;" but with updates that could enable higher DDR5 memory speeds. Each of the up to two "Eldora" Zen 5 CCDs has 8 CPU cores, with 1 MB of dedicated L2 cache per core, and 32 MB of shared L3 cache. The CCDs are very likely to be built on the TSMC 3 nm EUV silicon fabrication process.
Perhaps the most interesting aspect of the PCGH leak would have to be the TDP numbers being mentioned, which continue to show higher-performance SKUs with 170 W TDP, and lower tiers with 65 W TDP. With its CPU core-counts not seeing increases, AMD would bank on not just the generational IPC increase of its "Zen 5" cores, but also max out performance within the power envelope of the new node, by dialing up clock speeds. AMD could ride out 2023 with its Ryzen 7000 "Zen 4" processors on the desktop platform, with "Granite Ridge" slated to enter production only by Q1-2024. The company could update its product stack in the meantime, perhaps even bring the 4 nm "Phoenix" monolithic APU silicon to the Socket AM5 desktop platform. Ryzen 8000 is expected to retain full compatibility with existing Socket AM5, and AMD 600-series chipset motherboards.

1- Huge IPC increase
2- Major improvements to IMC
3- Hardening for higher clocks
That last one should be tailored to remove any shenanigans with X3D BIOS tinkering.
What I want to know is whether AMD will do something like this: combine a "regular" Zen5 Chiplet with a Zen5C chiplet (so the same two chiplet setup), but then you'd have 8 full power Zen5 cores from the first chiplet and then 16 Zen5c cores from the second chiplet (perhaps the reduced cache on the Zen5C chiplet could be offset by a v-cache addition?) and then you'd have a 24 core 48 thread hybrid Zen5 chip for AM5.
Regardless, these ML accelerators aren't really supported by anything as far as I can tell, for the time being they are useless.
PS. In Windows 11 has integrated AI features from few months.
Zen5 in general will utilize mature 4nm while bringing big architectural changes. So i dont expect changes in core counts or clock speeds. Or even L3 cache amounts.

Why not find a way to top out at 16 cores but have them on one CCD.
Still stuck at only 8 cores on one CCD.
Not good at all.
E-cores the heck with them.
And using only one chiplet say in 8600X would mean that a lot would go to waste. 10 out of 16 cores would need to be defective or fused off.
At the high end say 8950X it would be cheaper with one 16c chiplet but at the lower end it would make things more expensive.
So we can get more than 8 cores on a single CCD/ring.
No need for 16, but 10-12
While almost no games benefit from more than 8 cores in normal situations, there are some games with Ray Tracing on high in certain areas with high enough FPS like Toms Diner of Cyber Punk at more than 110 or so FPS that benefit slightly from more than 8, so more than 8 on a single CCD may be useful in future.
