It’s not everyday that you hear of products exceeding the expectations of the boffins that created them, but that seems to be exactly what has happened with the Xbox One and its memory performance.
Eurogamer report in some highly technical jargon, that “we’ll-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.
