SoC Powering Xbox One S Leverages 16 nm FinFET from TSMC

[btarunr]

Microsoft's new slim Xbox One S console achieves its slimness - including its inbuilt power-supply, by significantly reducing thermal load of its key components. This begins at the heart of the console, its SoC. A semi-custom chip by Microsoft and AMD, the SoC powering the Xbox One S is built on the 16 nm FinFET process at TSMC. The chip powering the original Xbox One was built on the same foundry's 28 nm node.

The new SoC isn't merely an optical shrink of the original 28 nm chip down to 16 nm FinFET, Microsoft added a few components to the chip, including an HEVC hardware decoder, hardware CODECs for Blu-ray UHD with HDR; and a revamped display controller with HDMI 2.0 and HDCP 2.2. The chip also performs 1080p to 4K UHD upscaling, with a native upscaling algorithm. The eSRAM memory bandwidth is increased slightly from 204 GB/s from 219 GB/s.

In response to Sony i guess.

The increased memory bandwidth is proberly to overcome the Xbox's one performance issues, where the PS4 is just a tad faster and better in many aspects.

Um i seem to remember bandwidth of XB1 wasn't anywhere near that. I remember them using DDR3 that seemed to top out around 60GB/s. PS4 used GDDR5 memory which runs around 176GB/s. So less MS changes it to gddr5 could be same issue all over again.

8GB DDR3 Clock: 2133MHz
Bandwidth: 68.26 GB/s
32MB eSRAM Bandwidth: 204 GB/s

and all so pointless because we know Scorpio is on the way.

The gpu clock was increased from 854 to 913mhz where the increased memory bandwidth is coming from. This has resulted in 11-15% (not sure the exact nunbers but the boost is evident) performance boost depending on the title. Tweaktown has an article about. @crazyeyesreaper and I had a conversation about it on facebook.

@arbiter what? Xbox One has two different memory types. ddr3 and eSRAM flash. The eSRAM is much much faster and now with the higher clocks its getting about 15gb/s more bandwidth.
