Stop listening to the random ppl here. You absolutely can add them as they are set up in parallel.
Quote by whom? Some know nothing posting here? Did you see my other post with Nick Baker's quote in it? Actual real world games/apps have been measured using 150 GB/s with just the eSRAM alone. Did you read my post at all?
Are you even reading what I typed? 176 GB/s is theoretical peak on PS4. 204 GB/s + 68 GB/s (272 GB/s) is theoretical peak combined on X1. Yes, it is much easier to hit the peak on PS4, but no game ever will. That isn't my point. If it were my point I would have been quoting 272 GB/s as the bandwidth for X1, which I wasn't. My point was real world, actual games/apps have been measured to hit 150 GB/s ONLY using the eSRAM and using that as an efficiency estimate for the main RAM nets us around 200 GB/s total bandwidth. Straight from the guy who designed it. He knows more than you do.
Even if we severely low ball the DDR3 RAM's real world usage efficiency it STILL easily eclipses the real world usage of the PS4's GDDR5. You could have 38% usage efficiency for the DDR3 in X1 and 100% perfect efficiency on PS4 and they'd still be equal.
...no, they aren't actually. One only does compression/decompression and some DMA work (PS4), the other does that on more than twice as many voices along with a bunch of other stuff. Stop.
Why is it so difficult for you guys to admit that X1 has hardware advantages in some areas over PS4?
