GeForce GTX 260 vs GeForce GTX 750

Intro

Compare all of that to the GeForce GTX 750, which makes use of a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this particular card. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GTX 260		182 Watts
	Difference: 127 Watts (231%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 260 should in theory be much better than the GeForce GTX 750 in general. (explain)

GeForce GTX 260		111888 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 31888 (40%)

Texel Rate

The GeForce GTX 260 is a little bit (approximately 13%) more effective at anisotropic filtering than the GeForce GTX 750. (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 4224 (13%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 750 is superior to the GeForce GTX 260, though not by far. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GTX 260		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 max amount of information (measured in MB 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 RAM, the result should be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
