NVIDIA quietly rolled out two entry-level notebook graphics processors, the GeForce MX130 and GeForce MX110. The two continue to be based on the "Maxwell" GPU architecture, and from the looks of it, appear to be based on the "GM108" silicon. With a core-configuration of 384 CUDA cores, 16 TMUs, and 8 ROPs, and GDDR5 memory, and mentioned that the MX130 is "2.5x" as fast as Intel UHD 620 graphics, while the MX110 is "1.5x" as fast, with slower DDR3 memory. Both support NVIDIA Optimus technology, besides the feature-set of the "Maxwell" architecture, and complete the MX100-series entry-level notebook GPU family led by the GP108-based MX150, which offers 4x UHD 620 performance.

NVIDIA's upcoming GM107 GPU, the first to be based on its next-generation "Maxwell" GPU architecture, reportedly features a different arrangement of CUDA cores and streaming multiprocessors to those typically associated with "Kepler," although the component hierarchy is similar. The chip reportedly features five streaming multiprocessors, highly integrated computation subunits of the GPU. NVIDIA is referring to these parts as "streaming multiprocessor (Maxwell)," or SMMs.

Further, each streaming multiprocessor features 128 CUDA cores, and not the 192 CUDA cores found in SMX units of "Kepler" GPUs. If true, GM107 features 640 CUDA cores, all of which will be enabled on the GeForce GTX 750 Ti. If NVIDIA is carving out the GTX 750 by disabling one of those streaming multiprocessors, its CUDA core count works out to be 512. NVIDIA will apparently build two GPUs on the existing 28 nm process, the GM107, and the smaller GM108; and three higher performing chips on the next-generation 20 nm process, the GM206, the GM204, and the GM200. The three, as you might have figured out, succeed the GK106, GK104, and GK110, respectively.
