GeForce 8800 GT 512MB vs GeForce GTX 650 Ti

Intro

The GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this particular model. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 650 Ti, which has core speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 memory. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

GeForce 8800 GT 512MB 105 Watts
GeForce GTX 650 Ti 110 Watts
Difference: 5 Watts (5%)

Memory Bandwidth

In theory, the GeForce GTX 650 Ti should be 50% quicker than the GeForce 8800 GT 512MB overall, because of its greater bandwidth. (explain)

GeForce GTX 650 Ti 86400 MB/sec
GeForce 8800 GT 512MB 57600 MB/sec
Difference: 28800 (50%)

Texel Rate

The GeForce GTX 650 Ti is much (about 77%) more effective at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

GeForce GTX 650 Ti 59392 Mtexels/sec
GeForce 8800 GT 512MB 33600 Mtexels/sec
Difference: 25792 (77%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti is the winner, by a large margin. (explain)

GeForce GTX 650 Ti 14848 Mpixels/sec
GeForce 8800 GT 512MB 9600 Mpixels/sec
Difference: 5248 (55%)

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 data (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at 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 the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
