We have been talking a lot about NVIDIA’s upcoming GeForce GTX 750 Ti graphics card and for those who do not know it will be based off the Maxwell GM107 GPU which you can see pictured below.
The GM107 is more or less a hybrid between the GK107 and GK106. While it has the same CUDA count as the GK106 it has the memory bus of the GK107. The area of the die has been reduced by 30% compared to the GK106. Power consumption has also been reduced by a lot, lower than any Kepler GPU. Almost all GeForce GTX 750 Ti models will not require any power connectors, although we might see a few that ship with them.
There are two versions of the GM107 GPU. The slower variant which is the GM107-300 will be used on the GeForce GTX 750. The faster one, the GM107-400 will of course be used on the GeForce GTX 750 Ti. The GM107-300 has 768 CUDA cores whereas the GM107-400 has 960 CUDA cores. Our friends over at VideoCardz have made a nice graph comparing the chips.
While GM107 is technically a new chip it really does not bring any new technology to the table. It is just better binned and more much efficient. So you could say that Maxwell is technically a Kepler refresh.
Both the NVIDIA GeForce GTX 750 ti and GeForce GTX 750 are set to launch on February 18th.
