Why?
Why dont they have full access to all 4? they have 8 cores in there right? 4big and 4small ones? why not use the small ones for the OS and other stuff?
SegataSanshiro said: Should be noted they use different types of ram. XBO is DDR3 PS4 is GDDR5 (you forgot the G) (their system memory is memory designed for graphics cards) NS is LPDDR4 |
Its why the PS4 has cheap memory (compaired to XB1 esram + ddr3 combo), thats still high memory bandwidth.
It uses the same type graphics cards normally do.
