I think this is in part to fix a mistake in the initial design of the the PS3.Yeah, I hope I'm not the only one that thinks that Sony is doing the ps4 just for the sake of it.
The ps3 is still such a high end device and even with the ps4...I'm still not exactly sure how much better the gap is.
I mean at least you can tell how big a jump is from ps1 to 2 to 3.
When the PS3 was made they went light on RAM, even by the standards of the time. In fairness both consoles did (as both have essentially 512mb). This is starting to cripple both consoles big time. I don't know if you remember the big Skyrim DLC issue for PS3 but that was basically caused by a RAM bottleneck. There are lots of ways developers have been sidestepping those issues as best they can(such as lowering resolution) but it's a problem that prevents both consoles from performing they way they otherwise could. Especially in a world where PC's have like 10 times that. When people wondered why the PS3 couldn't do party voice chat and why the XMB bar was always so slow, that's why. It literally didn't have the memory to spare.
That RAM is essential for developing games and there just isn't enough of it on either console anymore to keep up, and there hasn't been for a while really.
The PS4 has 8GB's of GDDR5 RAM. I'm not lie and say I fully understand what "GDDR" means. But my understanding is that high speed RAM designed for use in graphics cards. So basically it takes a console that has RAM inferior to almost any computer and upgrades it far past the current average for Gaming PCs.
