GeForce 8800 GTX vs GeForce GTX 750 Ti

Intro

Compare that to the GeForce GTX 750 Ti, which comes with core clock speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce 8800 GTX		155 Watts
	Difference: 95 Watts (158%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce GTX 750 Ti is a little bit (more or less 11%) more effective at AF than the GeForce 8800 GTX. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 4000 (11%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 750 Ti is superior to the GeForce 8800 GTX, though only just barely. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 2520 (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 max amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
