Pulling numbers out of my ass id say world usage might be seeing bandwidth around the 120GBs mark maybe?
Its a big advantage over just DDR3 for sure almost double, they had to have it they would be screwed without.
It just doesnt hold up to 256bit DDR5.
Sony just got lucky that they could up the DDR5 to 8gb. MS couldn't guarantee it would be available and needed the 8gb for thier planned OS functions, so they whent with thier only choice. Though im sure they could have cone for much higher bandwidth interface to ESRAM which would have made it much more ineresting, like how it was with PS2, im not sure why they didnt??
Luck has jack shit to do with this. This type of planning and procurement takes years. Mark Cerney started working on this in 2007 and to chalk it all up to luck is an insult. Also, what makes you think MS had GDDR5 in mind? Did they say that somewhere or are you making that up? I'm guessing the latter because MS was always under the impression the PS4 was only going to have 4GB of GDDR5 and when Sony dropped the bombshell they interestingly had to reschedule their initial Xbone reveal.
