bgassassin: Don't forget that as for the CPU, lherre has said that there is no mention of L3 cache in the manual. Would this affect the TDP dramatically? Also, I read you mention earlier that L3 cache would be unnecessary in a console. Mind giving me some quick education as to why? Thanks for making this a fun thread, btw.
I've also been thinking about the 32 MB eDRAM, which is apparently local to the GPU if rumor is to be believed. I wonder if this is 1T-SRAM (isn't this supposedly faster than eDRAM while still maintaining the small size advantage? Has this changed at all in recent years?) It seems that this might be necessary for Wii BC. Someone mentioned that the Wii CPU cannot run code from the GDDR3 because of the latency. This makes me wonder if the Wii U CPU will be able to access the 32 MB for BC purposes, even if the bus is not super-wide. Would this be possible if the the 1T-SRAM is located on its own module as the eDRAM is on the 360?
Also wondering if a 256-bit bus for the GDDR3 is a possibility. Would it be too pricey? Assuming similar clocks, wouldn't that negate the speed advantage of GDDR5 and keep the low latency of the GDDR3? This seems like something Nintendo would like to do, especially since it does not appear that 1t-SRAM will be the main RAM pool once again this time.
Good job, everyone! My brain is fine. Keep it up!
