GeForce 8800 Ultra vs GeForce GTX 970M

Intro

The GeForce 8800 Ultra features core clock speeds of 612 MHz on the GPU, and 1080 MHz on the 768 MB of GDDR3 RAM. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 970M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 924 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific model. It features 1280 SPUs as well as 80 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970M 75 Watts
GeForce 8800 Ultra 171 Watts
Difference: 96 Watts (128%)

Memory Bandwidth

Performance-wise, the GeForce 8800 Ultra should in theory be just a bit better than the GeForce GTX 970M in general. (explain)

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

Texel Rate

The GeForce GTX 970M should be much (more or less 89%) faster with regards to texture 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 is quite a bit (approximately 202%) more effective at anti-aliasing than the GeForce 8800 Ultra, and also should be capable of handling higher screen resolutions without slowing down too much. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
