Details on Microsoft’s Project Scorpio and how it might handle 4K gaming have been hard to come by ever since Microsoft announced the new platform. All we’ve known are a few basic specs, like the platform’s memory bandwidth (320GB/s), eight-core CPU, and available computational horsepower (6TFLOPS). Now we have more details thanks to a leaked PDF from a Microsoft developer website.

Eurogamer has the full details on the PDF, which doesn’t appear to be publicly available. According to Microsoft’s documentation, the Xbox Scorpio ditches the ESRAM cache the Xbox One relied on to deliver higher performance and acceptable frame rates. The PS4 and Xbox One are much more alike, architecturally speaking, than any previous pair of game consoles. ESRAM was one of the major differences between them — the Xbox One uses a 32MB ESRAM cache (divided into four 8MB blocks) to supplement its DDR3 memory interface, while the Sony PS4 has a unified 8GB GDDR5 memory pool.
