GeForce 8800 GTS (G92) vs GeForce GTX 650 Ti

Intro

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

Performance-wise, the GeForce GTX 650 Ti should in theory be quite a bit superior to the GeForce 8800 GTS (G92) in general. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 24320 (39%)

Texel Rate

The GeForce GTX 650 Ti should be a lot (more or less 43%) better at texture filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 17792 (43%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 650 Ti is a better choice, by far. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 4448 (43%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should 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 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 amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
