More on Maxwell GPUs
The popular online web site Videocardz has shared some more information on the latest NVIDIA Maxwell architecture and the GM107 core in particular. It appears that the new architecture comes with a different arrangement of the CUDA cores and stream processors used when compared to the Kepler generation. Still Maxwell will keep the same component hierarchy.
As to the GM107 core the chip features five streaming highly integrated multiprocessors that NVIDIA calls “streaming multiprocessor Maxwell” or SMMs for short. In addition each SMM comes with 128 CUDA cores while the Kepler architecture featured 192 CUDA cores per SMX unit. This means that the GM107 has 640 CUDA cores all of which will be operational on the GeForce GTX 750 Ti. Moreover the GTX 750 is likely to come with 512 CUDA cores if NVIDIA disables one SMM on this video card.
As of now NVIDIA’s plans include the GM107 and the smaller GM108 cores on the Maxwell architecture that will soon be followed by three more powerful chips – the GM206, GM204 and GM200 that will succeed the GK106, GK104 and GK110 cores respectively.
