GeForce GTX 275 vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which uses a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 RAM works at a speed of 1350 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 750 Ti		86400 MB/sec
	Difference: 40608 (47%)

Texel Rate

The GeForce GTX 275 should be a lot (approximately 24%) more effective at anisotropic filtering than the GeForce GTX 750 Ti. (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 9840 (24%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 275 is a better choice, but only just. (explain)

GeForce GTX 275		17724 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 1404 (9%)

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 largest amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
