Xbox vNext Codenamed Durango’s GPU Information Leaked

Two weeks back Xbox vNext’s CPU details got leaked and now the GPU block in the device got leaked today. The CPU will have
x64 Architecture, 8 CPU cores running at 1.6 gigahertz (GHz) with custom D3D11.1 class 800-MHz graphics processor which is detailed below.

It will come with the following GPU specs,

StatValue
Clock rate800 MHz
Compute
Shader cores12
Instruction issue rate12 SCs * 4 SIMDs * 16 threads/clock = 768 ops/clock
FLOPs768 ops/clock * (1 mul + 1 add) * 800 MHz = 1.2 TFLOPS
Interpolation( 768 ops/clock / 2 ops ) * 800 MHz = 307.2 Gfloat/sec
Geometry
Triangle rate2 tri/clock * 800 MHz = 1.6 Gtri/sec
Vertex rate2 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 cache38.4 Gelements/sec * 4 bytes = 153.6 GB/sec
Memory
Peak throughput from main RAM68 GB/sec
Peak throughput from ESRAM128 bytes/clock * 800 MHz = 102.4 GB/sec
ESRAM size32 MB
GSM size64 KB
LSM size12 SCs * 64 KB = 768 KB
L2 cache size4 x 128 KB = 512 KB (shared)
Texture
Bilinear fetch rate (4 bytes)4 fetches/clock * 12 SCs * 800 MHz = 38.4 Gtexels/sec
Bilinear data rate from cache38.4 Gtexels/sec * 4 bytes = 153.6 GB/sec
L1 cache size16 KB/SC * 12 SCs = 192 KB (nonshared)
Output
Color/depth blocks4
Pixel clear rate1 8×8 tile/clock * 4 DBs * 800 MHz = 204.8 Gpixel/sec
Pixel hierarchical Z cull rate1 8×8 tile/clock * 4 DBs * 800 MHz = 204.8 Gpixel/sec
Sample Z cull rate16 /clock * 4 DBs * 800 MHz = 51.2 Gsample/sec
Pixel emit rate4 /clock * 4 DBs * 800 MHz = 12.8 Gpixel/sec
