GeForce GTX 260 216SP 55 nm vs GeForce GTX 750

Intro

Compare those specifications to the GeForce GTX 750, which uses a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this particular model. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

GeForce GTX 750		80000 MB/sec
	Difference: 31888 (40%)

Texel Rate

The GeForce GTX 260 216SP 55 nm will be a lot (more or less 27%) faster with regards to texture filtering than the GeForce GTX 750. (explain)

GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 8832 (27%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 750 is superior to the GeForce GTX 260 216SP 55 nm, but not by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GTX 260 216SP 55 nm		16128 Mpixels/sec
	Difference: 192 (1%)

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 information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
