GeForce GTX 650 Ti 2GB vs GeForce GTX 750

Intro

The GeForce GTX 650 Ti 2GB has a core clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare that to the GeForce GTX 750, which makes use of a 28 nm design. nVidia has clocked the core speed at 1020 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this model. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti 2GB should be a 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 a lot (approximately 82%) more effective at texture filtering 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 the winner, but not by far. (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 moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
