GTX 950 : the younger one
The lower end of the GPU market spectrum is an interesting place, while the GPU makers hardly pays any attention to it the majority of the revenue comes from that so called “low end” area. That being said the lower end is not completely forgotten by the manufacturers completely, the card we have for review today is a new entrant in the low end arena : the GTX 950 from Nvidia

Diving into specifications, with the GTX 950 what we essentially have is a cut down version of the GM 206 which is present in GTX 960. GTX 950 loses one-quarter of its SMMs – going from 8 to 6 – bringing the CUDA core count down from 1024 to 768 with the memory bus/ROP clusters left intact, with 32 ROPs connected to a 128-bit GDDR5 memory bus.
Coming to the clock speed, the GTX 950 didnt took much of a cut with respect to the GTX 960, we see a wider delta between base clock and boost clock with a 1024MHz base and 1188MHz boost and a little cut on the memory clock from 7GHz to 6.6GHz whicH is more to create an artificial distinction since nobody ships a 6.6GHz GDDR5 speed grade as far as I know.
