GeForce GTX 275 vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which has GPU clock speed of 1020 MHz, and 2048 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Texel Rate

The GeForce GTX 275 is much (more or less 24%) more effective at texture 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

The GeForce GTX 275 will be a small bit (approximately 9%) more effective at full screen anti-aliasing than the GeForce GTX 750 Ti, and capable of handling higher resolutions more effectively. (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: Bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
