| VGKing said: 8GB GDDR5 UNIFIED memory. This is the only RAM that is available to PS4 and is shared by eveything.(This is a positive thing in case you don't understand) |
Not entirely. - There is Pro's and Con's to unified memory, one of those cons is that bandwidth is shared between everything communicating with Ram, in the end the PS4 will get much less than 176GB/s of bandwidth for graphics operations. - Don't get me started on memory contention and such...
The bonus to unified memory is ease of development and that each processor, be it GPU or CPU can talk to each other with one less trip in the middle, reducing latency, which is impacted anyway as GDDR5 is high latency.
But for the love of god, stop praising GDDR5 memory, I have more GDDR5 memory in my PC than the PS4 will have in it's entirety, it's amazing how people will grab a high number (Cell/GDDR5) and run with it, praising it till the cows come home, when in the end it's still inferior to other platforms.
