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 is set to run at a frequency of 1350 MHz on this card. It features 640 SPUs along with 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 much (approximately 24%) faster with regards to AF 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 should be a bit (approximately 9%) more effective at AA than the GeForce GTX 750 Ti, and also will be able to handle 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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number 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 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
