GM204 Hardware Architecture In-Depth
Figure 2: GM204 Full-chip block diagram
Like Fermi and Kepler, GM204 is composed of an array of Graphics Processing Clusters (GPCs), Streaming
Multiprocessors (SMs), and memory controllers. GM204 consists of four GPCs, 16 Maxwell SMs (SMM),
and four memory controllers. GeForce GTX 980 uses the full complement of these architectural
components (if you are not well versed in these structures, we suggest you first read the Kepler and
Fermi whitepapers).
Another version of the chip, with 13 SMs, will ship concurrently and be called GeForce GTX 970. In the
future we plan to offer additional products based on GM204 that will ship with different combinations
of GPCs, SMs, and memory controllers to address various segments of the graphics market.
