18 or 20 CU dont need 560 GB/s is a waste of money. You must get the same GB/s Tflops /CU.
560GB/s / 52 CU = 10.77 GB/s/CU
XXX GB/s/20 CU = 10.77 GB/s/CU ; XXX = Bandwidth 217.6 GB/s.
XXX GB/s/18 CU = 10,77 GB/s/CU ; XXX = Bancwidth 193 GB/s.
With this more or less in mind we could try to think of ram configurations.
20 CU ------ 10 RDNA CU ------- 2 Shaders engines, 2 Memory controller but 10 gb o memory ....... maybe divided memory? 8 chip, 6 chips 1 GB + 2 chips 2 GB? With 8 chips the can use GDDR5 more cheap. 256 bits memory is enought for 20 CU maybe 192 bits?
There is a lot configuration.
Let the bets begin
On memory, I'll go with a 192bit bus configured with 2 1GB modules and 4 2GB modules. 6GB video optimal + 4GB at 128bit. How risky that would be would depend on how much VRAM is on the 3060, which will likely become the defacto PC standard for the next generation. Seems odd, like why not just go with 12GB, but the same could be said for XSX not just going with 20GB.
Should be a new thread for lockhart guesses, might as well get the wrongness mapped.
