GeForce 8800 Ultra vs GeForce GTX 970M

Intro

The GeForce 8800 Ultra comes with a clock speed of 612 MHz and a GDDR3 memory speed of 1080 MHz. It also features a 384-bit bus, and makes use of a 90 nm design. It features 128 SPUs, 64 TAUs, and 24 Raster Operation Units.

Compare that to the GeForce GTX 970M, which makes use of a 28 nm design. nVidia has set the core frequency at 924 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular card. It features 1280 SPUs as well as 80 TAUs and 48 ROPs.

GeForce 8800 Ultra 103680 MB/sec
GeForce GTX 970M 96000 MB/sec
Difference: 7680 (8%)

Texel Rate

The GeForce GTX 970M will be much (approximately 89%) better at anisotropic filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 970M 73920 Mtexels/sec
GeForce 8800 Ultra 39168 Mtexels/sec
Difference: 34752 (89%)

Pixel Rate

The GeForce GTX 970M will be a lot (about 202%) more effective at anti-aliasing than the GeForce 8800 Ultra, and also able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 970M 44352 Mpixels/sec
GeForce 8800 Ultra 14688 Mpixels/sec
Difference: 29664 (202%)

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.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once 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 texture map elements (texels) that can be 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 higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
