GK104 block diagram received

The component hierarchy is essentially similar to the Fermi architecture. Undoubtedly, the most striking parameter of the NVIDIA GK104 GPU is the 1536 CUDA core, which is three times more than the GeForce GTX 580.

The chip size with TSMC's 28 nm manufacturing technology can be 295 square millimeters. The GigaThread engine continues to control the data processed and pending. The chip has 4 GPCs (Graphics Processing Cluster) where two SMs (Shader Multiprocessors) are located. It is important to mention that GPC works with shared resources and also includes a raster engine. The marketing machinery came into operation at this point, so the former SM unit was given the sonorous SMX name. The SMX includes a PolyMorph 2.0 engine, an instruction cache, 192 CUDA cores, and of course a first-level cache. 

Summarizing the data so far: the 4 GPCs contain 2 SMX arrays, i.e. we can talk about a total of 8 major organizations, which really assumes the existence of 1536 CUDA processors. Looking at the other elements of the chip, we can say that the four raster motors will mean a total of 32 units and the number of tessellators will be eight. Two more pieces of information can be read about the leaked images: the 128 Texturing (TMU) and the 256-bit memory bus.
