![]() ![]() The latter necessitated an SMX-wide crossbar that used unnecessary power to allow all execution units to be shared. This is in contrast to Kepler, where each SMX had 4 schedulers that scheduled to a shared pool of execution units. The structure of the warp scheduler was inherited from Kepler, with the texture units and FP64 CUDA cores still shared, but the layout of most execution units were partitioned so that each warp schedulers in an SMM controls one set of 32 FP32 CUDA cores, one set of 8 load/store units and one set of 8 special function units. The "SMX" streaming multiprocessor design from Kepler was also retooled and partitioned, being renamed "SMM" for Maxwell. Accordingly, the memory bus was reduced from 192 bit on Kepler (GK106) to 128 bit, reducing die area, cost, and power draw. ![]() The L2 cache was increased from 256 KiB on Kepler to 2 MiB on Maxwell, reducing the need for more memory bandwidth. These new chips introduced few consumer-facing additional features, as Nvidia instead focused more on increasing GPU power efficiency. ![]() Maxwell 107 chip on GTX 750 Ti graphics card with heatsink removed.įirst generation Maxwell GPUs (GM107/GM108) were released as GeForce GTX 745, GTX 750/750 Ti, GTX 850M/860M (GM107) and GeForce 830M/840M (GM108). The Maxwell architecture is used in the system on a chip (SOC), mobile application processor, Tegra X1.įirst generation Maxwell (GM10x) The architecture is named after James Clerk Maxwell, the founder of the theory of electromagnetic radiation. Maxwell introduced an improved Streaming Multiprocessor (SM) design that increased power efficiency, the sixth and seventh generation PureVideo HD, and CUDA Compute Capability 5.2. The final and lowest spec Maxwell 2.0 card was the GTX950 released on A second generation of Maxwell-based products was introduced on Septemwith the GeForce GTX 970 and GeForce GTX 980, followed by the GeForce GTX 960 on January 22, 2015, the GeForce GTX Titan X on March 17, 2015, and the GeForce GTX 980 Ti on June 1, 2015. First-generation Maxwell GPUs (code numbers GM10x) are also used in the GeForce 800M series and the Quadro Kxxx series. Earlier GeForce 700 series GPUs had used Kepler chips with the code numbers GK1xx. Both were released on February 18, 2014, both with the chip code number GM107. The first Maxwell-based products were the GeForce GTX 745 (OEM), GeForce GTX 750, and the GeForce GTX 750 Ti. The Maxwell architecture was introduced in later models of the GeForce 700 series and is also used in the GeForce 800M series, GeForce 900 series, and Quadro Mxxx series, as well as some Jetson products, all manufactured with TSMC's 28 nm process. Maxwell is the codename for a GPU microarchitecture developed by Nvidia as the successor to the Kepler microarchitecture. Photo of James Clerk Maxwell, eponym of architecture ![]()
