GeForce 8800 Ultra vs GeForce GTX 870M

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 uses a 90 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 24 ROPs.

Compare that to the GeForce GTX 870M, which features core speeds of 941 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1344 SPUs along with 112 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 870M 110 Watts
GeForce 8800 Ultra 171 Watts
Difference: 61 Watts (55%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 Ultra will be 8% quicker than the GeForce GTX 870M in general, because of its higher data rate. (explain)

GeForce 8800 Ultra 103680 MB/sec
GeForce GTX 870M 96000 MB/sec
Difference: 7680 (8%)

Texel Rate

The GeForce GTX 870M is quite a bit (approximately 169%) better at AF than the GeForce 8800 Ultra. (explain)

GeForce GTX 870M 105392 Mtexels/sec
GeForce 8800 Ultra 39168 Mtexels/sec
Difference: 66224 (169%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 870M is superior to the GeForce 8800 Ultra, by far. (explain)

GeForce GTX 870M 22584 Mpixels/sec
GeForce 8800 Ultra 14688 Mpixels/sec
Difference: 7896 (54%)

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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
