Can someone explain this a little more clearly?
from what I understand, the PS3 has 256MB dedicated VRAM at 3.2GHZ and 256MB at 700MHZ dedicated to system
while the 360 has a unified 512MB at 700MHZ which can be divided as devs need
so...realistically does a game like GoW running at 720p need to use up more than 256MB for Video?
or do people say unified is better because they could if they wanted to?
also, when they say that GoW is the reason MS decided to go with 512MB Ram do they mean Epic convinced them to unify the ram, or that MS figured other games will run fine with 256MB shared between video and system?
I really have no clue about this stuff please enlighten me if i'm wrong.
the ps3 has 256MB of DDR3 VRAM at 700MHz (well other reports are saying 650MHz) and 256MB XDR memory running at 3.2GHz.
the 360 has a unified 512MHz of 700MHz DDR3. the developers can split the 512MB however way they choose. judging by epics comments of GoW not possible on the ps3 i would imagine that GoW uses more the 256MB for textures, but i could be wrong. any game is possible on any system if you scale it back enough. just from reading, most developers prefer unified because it offers more flexibility.
epic may have played a role in microsoft's desicion, but the entire development community knew/wanted microsoft to double up the memory in the 360. If mark reins story is true, then the pic of GoW running on only 256MB of memory may have been the final smack to the head to issue the final answer, but they werent the only factor to consider.
long story short, devs knew 256MB wouldnt be enough and thankfully microsoft listened.
