The Xbox One GPU was a high-end graphics card by AMD, launched in November 2013. Built on the 28 nm process, and based on the Durango graphics processor, in its X871363-001 variant, the card supports DirectX 11.2. The Durango graphics processor is a large chip with a die area of 363 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 853 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 499 US Dollars.

Durango GPU Notes

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

FLOPs:
768 ops/clock * (1 mul + 1 add) * 800 MHz = 1.2 TFLOPS

Interpolation:
(768 ops/clock / 2 ops) * 800 MHz = 307.2 Gfloat/sec

Triangle rate:
2 tri/clock * 800 MHz = 1.6 Gtri/sec

Vertex rate:
2 vert/clock * 800 MHz = 1.6 Gvert/sec

Vertex/buffer fetch rate: (4 bytes)
4 elements/clock * 12 SCs * 800 MHz = 38.4 Gelement/sec

Vertex/Buffer data rate from cache:
38.4 Gelements/sec * 4 bytes = 153.6 GB/sec

Peak throughput from main RAM:
68.2 GB/sec

Peak throughput from ESRAM:
128 bytes/clock * 800 MHz = 102.4 GB/sec

ESRAM size:
32 MB

GSM size:
64 KB

LSM size:
12 SCs * 64 KB = 768 KB

L2 cache size:
4 x 128 KB = 512 KB (shared)

Bilinear fetch rate: (4 bytes)
4 fetches/clock * 12 SCs * 800 MHz = 38.4 Gtexels/sec

Bilinear data rate from cache:
38.4 Gtexels/sec * 4 bytes = 153.6 GB/sec

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

Pixel clear rate:
1 8×8 tile/clock * 4 DBs * 800 MHz = 204.8 Gpixel/sec

Pixel hierarchical Z Rate:
1 8×8 tile/clock * 4 DBs * 800 MHz = 204.8 Gpixel/sec

Sample Z rate:
16 /clock * 4 DBs * 800 MHz = 51.2 Gsample/sec
