GeForce GTX 750 vs 650 |
Expected June, 2013
Nvidia GeForce GTX 750
- 1 GHz
- 2 GB GDDR5
by hassan-mujtaba (Oct, 2013)The GeForce GTX 660 Ti on the other hand is around 5% faster but we can see overclocked models closing the difference gap so overall, we are looking at a solid mainstream performer.

Colorful GeForce GTX 650
- 1.1 GHz

by techPowerUp! (Sep, 2012)Temperatures are super low due to a high fan speed, but this offers no tangible benefits to the user - a quieter fan would be better.Price-wise, the KFA² GTX 650 EX OC comes at NVIDIA's reference design price, which is nice given the custom cooler and small overclock out of the box.

Features Key features of the GeForce GTX 750 vs 650
memory bandwidth Rate at which data can be read from or stored in onboard memory
GeForce GTX 750 | by hassan-mujtaba (Sep, 2013)The most intresting part is that the card actually comes with a 256-bit memory interface with 2 GB VRAM.
pixel rate Number of pixels a graphics card can render to the screen every second
GeForce GTX 750 | by hassan-mujtaba (Oct, 2013)As for performance, the card looks real nice would a performance advantage of 10% over GeForce GTX 660 which has the same specifications but lower ROPs and a 192-bit interface.
texture rate Speed at which a graphics card can perform texture mapping
GeForce GTX 750 | by hassan-mujtaba (Oct, 2013)NVIDIA’s AIB partners would have the freedom to release all the custom models they want at around the same range as the official pricing which would be set to compete against the sub-$199 market which is entirely going to be dominated by AMD’s mainstream and entry level Radeon R7 lineup.
floating point performance How fast the gpu can crunch numbers
GeForce GTX 650 | by Steven-L.-White--Steven-Lee-White-aka-AceGoober (Feb, 2013)With the exception of a couple graphics intensive games such as Crysis 1 this card delivers a smooth gaming experience even when detail levels are set to the highest.
shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading
GeForce GTX 650 | by techPowerUp! (Sep, 2012)The GK107 GPU is using a scaled down Kepler architecture design with just 16 ROPs and 384 shaders.
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes
GeForce GTX 750 | by hassan-mujtaba (Sep, 2013)The specs show that the GeForce GTX 750 Ti GPU would feature 960 Cores, 32 ROP and 80 TMUs which we can assume is the revised GK106 core, running at 1033 MHz base and 1098 MHz boost speeds.
