| curl-6 said: UC4 is increased in scope over UC3, so the Wii U's extra power over PS3 would have to be put to work on that. And eDRAM is very useful for some things, like triple buffering to prevent screen tearing or graphics data that reqires fast access, but it's ultimately 32MB. It doesn't magically expand to cover the 4GB difference in RAM between Wii U and its rivals. And Xbone has 32MB eDRAM as well, so it's not a Wii U exclusive advantage. Shrinking a game's memory footprint from 5GB to 1GB would require significant work. |
The X1 has 32MB of eSRAM, not eDRAM, but past that you're right. Translating 5GB of DDR3 + 32MB of eSRAM into 1GB of DDR3 + 32MB eDRAM wouldn't be a simple affair.
The WiiU's eDRAM would be able to bridge the gap in specific situations (it's faster than the X1's eSRAM), but as you said, there's ultimately only 32MB of it. There are pretty firm limits as to what it can and can't do. Reducing a memory footprint by 13,000%~ falls outside those limits :p
