| curl-6 said: What the thread should have been titled is "did Sony just explain why Wii U's RAM isn't too slow", but no, it had to be framed as a console war pissing contest. *Sigh* |
"Sony" did no such thing - Cerny was explaining two approaches they were considering for PS4 (and btw, that was quite some time ago), and why they decided to go with unified pool (and that he stated in even older interview on Gamasutra). Not sure why people even pay attention to some random guy on Youtube who obviously has absolutely zero understanding of how hardware works, and decided to share his "knowledge" with rest of the world weeks after that conference.
For the rest who know a thing or two about hardware, WiiU's approach is something that was around for quite some time now, so not sure what the fuss is all about. I was giving example of how (rumored) WiiU equivalent GPU performs with different memory bandwidths several times, but here it is again (PS4 is between 7850 and 7870, XOne is between 7770 and 7790):
7870 = 1.22x 7850= 1.15x 7790 = 1.28x 7770 = 3.56x 5550 (GDDR5; 51.2GB/s) = 1.24x 5550 (GDDR3; 25.6GB/s) = 1.32x 5550 (DDR2; 12.8GB/s)
Last 5550 has same bandwidth as WiiU's main system memory, but due to eDRAM it is not to be expected for WiiU to perform on that level - the question remains how good you can use eDRAM to get more toward that GDDR5 level...that question is valid for XOne too, specially since it has MOVE engines in addition to eSRAM.
EDIT: Added comparisson chart
DISCLAIMER - I will not be replying to either NintendoWitness or ShinobiTroll, so don't bother jumping in.
