Anybody think 8 gb of GDDR5 is a mistake for PS4

I agree, 3gb of ram just for the OS means it's a chunkier OS than even Windows Vista and certainly a massive jump over the Xbox 360's 32Mb-48Mb~ OS that it has right now.

Also, the PS4 doesn't have a "Ram advantage". DDR3 is lower latency than GDDR5, whether the DDR3's bandwidth will hold back the Xbox 720's fillrate at 1080P remains to be seen, but even after a couple of years I expect both the Xbox 720 and Playstation 4 to start having it's games run at 720P again, so that bandwidth advantage should mean less.

We also have no idea if the PS4 has a 64bit memory bus or a 128bit memory bus or if the Xbox 360's memory bus is 256bit, DDR3 with the right set-up can be competitive with GDDR5 in terms of memory bandwidth, it's probably something we won't know 100% untill all the cards have fallen into place.

For 170GB/s? 256bits.
