We have two SKUs left in the Stoney Ridge library left which are A9-9435 and A6-9235.
The three possibilities after the above is... continuing from previous posts.
1. 22FDX APU(no chiplets)
2. 22FDX IOD(MC_Bufer,GMC_Buffer,GFX_PCIe,GPP_PCIe,USB,DCN,etc) + 12FDX ACD(CPU/GPU/MMN w/ package cache(shared/unified L3))
3. Both with 1st first and 2nd second.
My expectations thus speculation on the 22FDX at this moment; New cluster-based multithreading microarchitecture and up-ported lightweight RDNA.
With that the 12FDX; Enhanced version of the above and more cores via more modules and possibly heavyweight RDNA with more WGPs/CUs.
New CMT architecture => Smaller cores and module from Excavator, with two things lower leakage thus lower power, and higher frequency at lower watts.
The best average is 45% higher frequency to 45% lower power at 45% less area on logic side.
If capable 125 mm squared to ~90 mm squared is like 400+ good dies to 600+ good dies. Even with the worst yields on GlobalFoundries 22FDX proven dies(less than 5 mm to greater than 115 mm squared). Which are ~84% good yields is 500+ good dies with a die of approximately around 90 mm squared.
1st APU is direct successor to Stoney Ridge. 64b, same IO, same core count but new module/core, same gpu count but new gpu architecture.
2nd APU is an indirect successor to Raven2 and shares the IOD with the direct successor 7nm+ Accelerated Complex die; CPU cores, GPU cores, Multimedia cores(VCN(Video Decode/Encode) and ACP(Audio Decode/Encode)).
The other first is 22FDX IOD + 22FDX ACD. Sneaking into the Raven2/Dali platform. Same IOD in both 1st and 2nd, different ACD between the two. With the possibility of the 7nm+ ACD using the same 22FDX IOD. The 22FDX IO die has less I/O compared to the 12LP IO die. 22FDX IOD compares directly with Raven2 IMC/FCH. This directly changes the 1st calc of 90 mm squared, since it is two dies rather than one.
IOD 22FDX; (guess)
