Durango 2 GPU Notes

Generation: Sea Islands
Codename: Gladius / Bishop
CLRX: GCN 1.0

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:
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 * 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

Pixel rate:
4 /clock * 4 DBs * 914 MHz = 14.624 Gpixel/sec
