GeForce 8800 Ultra vs GeForce GTX 750 Ti

Intro

Compare those specs to the GeForce GTX 750 Ti, which uses a 28 nm design. nVidia has clocked the core speed at 1020 MHz. The GDDR5 memory works at a speed of 1350 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 750 Ti		60 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 111 Watts (185%)

Memory Bandwidth

The GeForce 8800 Ultra, in theory, should be a little bit faster than the GeForce GTX 750 Ti overall. (explain)

GeForce 8800 Ultra		103680 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 17280 (20%)

Texel Rate

The GeForce GTX 750 Ti will be a small bit (approximately 4%) faster with regards to texture filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 1632 (4%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 750 Ti is a better choice, though only just barely. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 1632 (11%)

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 max amount of information (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
