The Xbox One S GPU is a high-end graphics card by AMD, launched in August 2016. Built on the 16 nm process, and based on the Durango 2 graphics processor, in its M1004145-001 variant, the card supports DirectX 12.0. The Durango 2 graphics processor is an average sized chip with a die area of 240 mm² and 5,000 million transistors. It features 768 shading units, 48 texture mapping units and 16 ROPs. AMD has placed 8,192 MB DDR3 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 914 MHz, memory is running at 1066 MHz.
Being a igp card, its power draw is rated at 95 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Its price at launch was 399 US Dollars.

Durango 2 GPU Notes

Instruction issue rate:
12 SCs * 4 SIMDs * 16 threads/clock = 768 ops/clock

FLOPs:
768 ops/clock * (1 mul + 1 add) * 914 MHz = 1.404 TFLOPS

Interpolation:
(768 ops/clock / 2 ops) * 914 MHz = 350.97 Gfloat/sec

Triangle rate:
2 tri/clock * 914 MHz = 1.828 Gtri/sec

Vertex rate:
2 vert/clock * 914 MHz = 1.828 Gvert/sec

Vertex/buffer fetch rate: (4 bytes)
4 elements/clock * 12 SCs * 914 MHz = 43.872 Gelement/sec

Vertex/Buffer data rate from cache:
43.872 Gelements/sec * 4 bytes = 175.488 GB/sec

Peak throughput from main RAM:
68.2 GB/sec

Peak throughput from ESRAM:
128 bytes/clock * 914 MHz = 116.992 GB/sec

ESRAM size:

4 fetches/clock * 12 SCs * 914 MHz = 43.872 Gtexels/sec

Bilinear data rate from cache:
43.872 Gtexels/sec * 4 bytes = 175.488 GB/sec

L1 cache size:
16 KB/SC * 12 SCs = 192 KB (nonshared)

Pixel clear rate:
1 8×8 tile/clock * 4 DBs * 914 MHz = 233.984 Gpixel/sec

Pixel hierarchical Z Rate:
1 8×8 tile/clock * 4 DBs * 914 MHz = 233.984 Gpixel/sec

Sample Z rate:
16 /clock * 4 DBs * 914 MHz = 58.496 Gsample/sec
