We finally saw Maxwell yesterday, with a new design for the SMs called SMM each of which consist of four blocks of 32 dedicated, non-shared CUDA cores.  In theory that should allow NVIDIA to pack more SMMs onto the card than they could with the previous SMK units.  This new design was released on a $150 card which means we don't really get to see what this new design is capable of yet.  At that price it competes with AMD's R7 260X and R7 265, at least if you can find them at their MSRP and not at inflated cryptocurrency levels.  Legit Reviews contrasted the performance of two overclocked GTX 750 Ti to those two cards as well as to the previous generation GTX 650Ti Boost on a wide selection of games to see how it stacks up performance-wise which you can read here.

That is of course after you read Ryan's full review.

"NVIDIA today announced the new GeForce GTX 750 Ti and GTX 750 video cards, which are very interesting to use as they are the first cards based on NVIDIA's new Maxwell graphics architecture. NVIDIA has been developing Maxwell for a number of years and have decided to launch entry-level discrete graphics cards with the new technology first in the $119 to $149 price range. NVIDIA heavily focused on performance per watt with Maxwell and it clearly shows as the GeForce GTX 750 Ti 2GB video card measures just 5.7-inches in length with a tiny heatsink and doesn't require any internal power connectors!"
