Memory is shared between the CPU and GPU, and if I'm decoding the DRAM part numbers correctly it looks like these are 16-bit devices giving the Wii U a total of 6.4GB/s of peak memory bandwidth. That doesn't sound like a lot, but the Wii U is supposed to have a good amount of eDRAM for both the CPU and GPU to use." Edit - I think Anand made a mistake with the maths... 800Mhz @ 16 bits give it 12.8GB/s and not 6.4GB/s... even so it's too little but explain why the multiplayer in BOPS2 for Wii U have static shadows. |
Not sure he did - 800MHz * 2bytes (16bits) * 4 modules = 6.4GByte/s.
I think you calculated in Gbits: 800MHz * 16bit = 12.8Gbits/s (*4 modules = 51.2Gbits/s = 6.4GBytes/s)
I might be wrong though, not completely sure if this is correct calculus.
