GeForce GTX 650 Ti 2GB vs GeForce GTX 750

Intro

The GeForce GTX 650 Ti 2GB has a GPU core clock speed of 928 MHz, and the 2048 MB of GDDR5 memory runs at 1350 MHz through a 128-bit bus. It also is made up of 768 SPUs, 64 TAUs, and 16 ROPs.

Compare those specifications to the GeForce GTX 750, which comes with a clock frequency of 1020 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 55 Watts
GeForce GTX 650 Ti 2GB 110 Watts
Difference: 55 Watts (100%)

Memory Bandwidth

The GeForce GTX 650 Ti 2GB, in theory, should perform a little bit faster than the GeForce GTX 750 in general. (explain)

GeForce GTX 650 Ti 2GB 86400 MB/sec
GeForce GTX 750 80000 MB/sec
Difference: 6400 (8%)

Texel Rate

The GeForce GTX 650 Ti 2GB is quite a bit (more or less 82%) more effective at AF than the GeForce GTX 750. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
GeForce GTX 750 32640 Mtexels/sec
Difference: 26752 (82%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 750 is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 750 16320 Mpixels/sec
GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Difference: 1472 (10%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
