GeForce GTX 650 Ti 2GB		110 Watts
	Difference: 5 Watts (5%)

Memory Bandwidth

Performance-wise, the GeForce GTX 650 Ti 2GB should in theory be a lot better than the GeForce 8800 GT 512MB in general. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 28800 (50%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be quite a bit (approximately 77%) more effective at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 25792 (77%)

Pixel Rate

The GeForce GTX 650 Ti 2GB will be a lot (more or less 55%) more effective at FSAA than the GeForce 8800 GT 512MB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 650 Ti 2GB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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