GeForce 8800 Ultra vs GeForce GTX 650 Ti 2GB

Intro

The GeForce 8800 Ultra has 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 Texture Address Units and 24 Rasterization Operator Units.

Compare all of that to the GeForce GTX 650 Ti 2GB, which uses a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this specific model. It features 768 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB 110 Watts
GeForce 8800 Ultra 171 Watts
Difference: 61 Watts (55%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 Ultra is 20% faster than the GeForce GTX 650 Ti 2GB in general, because of its greater data rate. (explain)

GeForce 8800 Ultra 103680 MB/sec
GeForce GTX 650 Ti 2GB 86400 MB/sec
Difference: 17280 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be a lot (about 52%) more effective at texture filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
GeForce 8800 Ultra 39168 Mtexels/sec
Difference: 20224 (52%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 650 Ti 2GB is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
GeForce 8800 Ultra 14688 Mpixels/sec
Difference: 160 (1%)

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 MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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