GeForce GTX 280 vs GeForce GTX 750 Ti

Intro

Compare that to the GeForce GTX 750 Ti, which features a core clock frequency of 1020 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

GeForce GTX 750 Ti		86400 MB/sec
	Difference: 55296 (64%)

Texel Rate

The GeForce GTX 280 will be a little bit (approximately 18%) more effective at texture filtering than the GeForce GTX 750 Ti. (explain)

GeForce GTX 280		48160 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 7360 (18%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 280 is the winner, but not by far. (explain)

GeForce GTX 280		19264 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 2944 (18%)

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 (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
