GeForce GTX 260 Core 216 vs GeForce GTX 750 Ti

Intro

Compare all that to the GeForce GTX 750 Ti, which has GPU clock speed of 1020 MHz, and 2048 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce GTX 260 Core 216		202 Watts
	Difference: 142 Watts (237%)

Memory Bandwidth

In theory, the GeForce GTX 260 Core 216 should be a lot faster than the GeForce GTX 750 Ti in general. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 25488 (30%)

Texel Rate

The GeForce GTX 260 Core 216 is just a bit (more or less 2%) more effective at texture filtering than the GeForce GTX 750 Ti. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 672 (2%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 750 Ti is superior to the GeForce GTX 260 Core 216, though only just barely. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce GTX 260 Core 216		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 data (in units of MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
