GeForce GTX 260 216SP 55 nm vs GeForce GTX 750

Intro

Compare all that to the GeForce GTX 750, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this specific card. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 750		32640 Mtexels/sec
	Difference: 8832 (27%)

Pixel Rate

The GeForce GTX 750 should be a little bit (about 1%) better at FSAA than the GeForce GTX 260 216SP 55 nm, and able to handle higher resolutions without losing too much performance. (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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at 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 a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 potential to reach the maximum fill rate.
