So 0.4% of the Xbox one memory is higher bandwidth than PS4, the other 99.6% of the memory pool is much higher bandwidth on the PS4.

That is something most people misunderstand. The esram may only be a small fraction of the total ram, but if the gpu can do 99% of the work it has to do in esram, then you are obviously ok. How much edram/esram you need has been tested endlessly by whoever makes chips . It seems that 32MB is some kind of "sweet spot" if you look at <=1080p images. Ms has built a very complex infracstructure around the esram bottleneck to ensure they get as close as possible to 100% efficiency.

Trust me.  I am a BSEE.  I understand this stuff isn't always black and white.

This anandtech article says it pretty well.   I think at the end of the day, GDDR5 is the better choice for a gaming centric console, hands down.  Microsoft is most certainly aiming for a media hub, and there could be some advantages to DDR3 there.  But from a games perspective, its hard to argue against GDDR5 being better, especially AT 1080P

Also, 32MB was probably more of a "cheap" spot too in terms of cost.


I don't believe that is the argument.

I think the argument Microsoft is making is that while Sony has the performance specs, it doesn't necessarily equate to a significant advantage due to the limitations of the choices made.

And the limitations of the PS4 are a unified memory, a easy to use and program architecture, and a stronger console. I would love to have those limitations.


Acording to Ethomaz:

The PS4 can´t swap into games or apps. You might not suspend  Knack and go play a multplay match of COD with yuor friends.
