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
