GeForce GTX 650 Ti 2GB vs GeForce GTX 750

Intro

Compare those specs to the GeForce GTX 750, which has a core clock speed of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is made up 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

In theory, the GeForce GTX 650 Ti 2GB is 8% quicker than the GeForce GTX 750 overall, due to its greater data rate. (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 should be a lot (approximately 82%) faster with regards to 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 a high screen resolution 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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
