Really? As cheap as memory is this all they put in the next gen system?
However, an important distinction lies in the type of RAM on offer. Each of the PS4's 2-4 GB will be GDDR5 RAM, which is notably faster and more efficient at graphics processing than the DDR3 or DDR4 expected to feature in Xbox 720. NeoGAF techies estimate that this disparity will thus even out, with PS4's memory speed likely compensating for Xbox 720's larger amount (and vice versa)
I understand it's faster but one of the biggest complaints some devs have had of the current gen systems was the amount of ram limiting certain actions in games.
4GB of RAM is more than enough for any game, especially at GDDR5.
That's because the games developed now have to make sure it's more than enough. I see this as a possible bottle neck again going forward.
Consoles once again holding back game development.
The PS4 will feature 2GB Unified RAM, shared between the CPU and GPU.
their PC is still better
