GeForce 8800 Ultra vs GeForce GTX 980

Intro

Compare that to the GeForce GTX 980, which features GPU core speed of 1126 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 64 ROPs.

GeForce 8800 Ultra		103680 MB/sec
	Difference: 120320 (116%)

Texel Rate

The GeForce GTX 980 is much (more or less 268%) better at anisotropic filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 980		144128 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 104960 (268%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 980 is superior to the GeForce 8800 Ultra, by far. (explain)

GeForce GTX 980		72064 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 57376 (391%)

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 largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
