[QUOTE="Tighaman"]im going to say it again for torm and the rest of you fanboys its a reason that the greatest minds in gaming business never thought to put gddr5 as system ram its not efficient for the cpu especially if the cpu is weak. 7850 doesnt use all 32 rops please read why on your own All them ACEs dont mean anything 7950 has only two ACEs and blow the gpu in the ps4 away. And back to battlefield 4 its been two demos for that game ps4 specs and x1 specs all the multiplatform game I remember used to run the same demos for the same game but not this time not this gen why? Theres plenty of NEW AMD GPUs if you looked at just specs have less 12 cu and 16 rops and will blow that 7850 out the water with MS you always look ahead and never in the past.tormentos

I am going to tell you this again,GDDr5 need to be solder to the PCB it can't be made yet into Dimm forms so basically that is what has stop GDDR5 from taking over on your PC.

The PS4 GPU is strong than the 7850 and yes 32 ROP is need it when you go for higher resolutions than 1080p or 3D,Aces is what allow GCN to execute out of order instruction,since GCN is an in order GPU,more ACES more out of order executions,the PS4 GPU is actually more custom to take advantage of compute than the 7950 regarless of the 7950 having more power,which mean nothing because the damn xbox one doesn't have a damn 7950 it has a gimped 7790 with 2 CU less and lower clock speed.
Furthermore, even if GDDR5 is able to be used as system RAM, no manufacturer is going to bother, since CPUs require really low bandwidth and DDR3's bandwidth is sufficient to feed modern-day CPUs quite well. There's no point in putting a more expensive GDDR5 when most of its bandwidth would't even be utilized.
CPUs right now are several generations behind GPUs in terms of power, so they're not able to utilize high amounts of bandwidth. To get an idea, PS4's CPU can utilize just 20 GB/s. It's the GPU that needs to have high bandwidth.
