Digital Foundry put up an article on X1s memory and the speeds it produces. Apparently tests show that the memory is incredibly capable and 88% more than MS had actually thought before.
Well-placed development sources have told Digital Foundry that the ESRAM embedded memory within the Xbox One processor is considerably more capable than Microsoft envisaged during pre-production of the console,
with data throughput levels up to 88 per cent higher in the final hardware.
Bandwidth is at a premium in the Xbox One owing to the slower DDR3 memory employed in the console, which does not compare favourably to the 8GB unified pool of GDDR5 in the PlayStation 4.
The 32MB of "embedded static RAM" within the Xbox One processor aims to make up the difference, and was previously thought to sustain a peak theoretical throughput of 102GB/s -
useful, but still some way behind the 176GB/s found in PlayStation 4's RAM set-up.
Now that close-to-final silicon is available, Microsoft has revised its own figures upwards significantly, telling developers that 192GB/s is now theoretically possible
Things just got Reaaaal interesting. Cows positives of the PS4 over X1 seem to be fading fast these days. This is shaping up to be one hell of a console war
