Forums - Gaming - Anybody think 8 gb of GDDR5 is a mistake for PS4

At launch it is overkill. Even after the second wave of games it will be overkill. In 7 years though it could be the bottleneck. Sony doesn't want a repeat of this gen. I expect EVERY social feature in the 720 to be ported to PS4 now that it has so much extra ram.

The GPU doesn't even have enough power to utilize 8 GB.


This is shared memory... I thought you knew that?

Yes. 1 GB is going to be used for the OS.

What will you do with the other 7?

Shared memory means it's shared between the CPU and GPU. Sure 1 GB or so will go to the OS but the CPU needs more then that. Pretty much everything in a game that isn't pixels is handled by the CPU. That takes a lot of ram. On the PS3 50% of the ram was for CPU operations and 50% was for GPU operations. If that same ratio carried over (unlikely), the GPU would only be using 4 GB.

The GPU is too weak to use up 4 GB. The max it'll be able to handle would be around 1.5 GB. That leaves us with a whopping 5.5 GB for CPU operations.

Considering you were confused about shared memory, I'd need a source for that stat.

Or if you want really long loading screens :/

Quote me where I was confused about shared memory.

Crysis 3 runs on the AMD 7870 at approximately 30~35 FPS. Crysis 3 uses up approximately 1.5~2GB of VRAM. That's all you need to know.

You just forget the Crysis 3 uses System RAM too.

Um no. The PS4 isn't a PC.

i'm not really sure but i keep hearing how expensive the ultra fast ram is, so i started thinking wouldn't it be cheaper if had they gone with a 2.5 gflops GPU and 4gb gddr5, wouldn't that make the system cheaper and give it better graphics, i just don't see how they could use the 8gb or even 4gb, the budget for the game would be insane.

Maybe the ability to stand-by any game and resume it instantly is worth the extra cost... plus Sony always plans for longer console life-cycle aiming at 10 years.

Finally... the next Xbox also has 8 core processor and 8 GB of DDR3 memory... the only difference is the DDR3 vs. GDDR5. I believe Xbox changed theirs from 4GB to 8GB after learning PS4 spec...

X360 had also gone from 256MB to 512MB in final pre-release year based on some late decisions to just eat the cost cause the performance boost was worth it.
