nVidia GK104
Product name (top solution): GeForce GTX 680 (but not entirely sure)
28nm production at TSMC, the area approximately 340mm ˛ (unofficial estimate)
4 Graphics Processing Cluster (GPC)
4 Streaming Multiprocessors (SM) aka shader clusters per GPC, ergo a total of 16 shader clusters for the GK104-chip
96 stream processors (SP) aka shader shader units per cluster, ergo a total of 1536 shader units for the GK104-chip
8 texture units (TMU) aka shader texture units per cluster, ergo a total of 128 units of textures for the GK104-chip
32 raster operation units (ROPs)
256-bit DDR memory interface (up to GDDR5)
Chip clock (top model): 950 MHz
Elimination of Hotclocks, no extra clock speed of the shader units more
Single-precision arithmetic performance 2.9 teraflops , double precision with 1:6 = 486 DP GFlops processing power, 121 Texturierleistung Gtex / sec
Memory clock (top model): 2500 MHz, memory bandwidth so that at 160 GB / sec
2048 MB of GDDR5 memory configuration
