GeForce 8800 GT 512MB vs Geforce GTX 760

Intro

Compare all of that to the Geforce GTX 760, which features core speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1152 SPUs as well as 96 TAUs and 32 ROPs.

GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 60480 (180%)

Pixel Rate

The Geforce GTX 760 will be quite a bit (about 227%) better at FSAA than the GeForce 8800 GT 512MB, and should be capable of handling higher resolutions more effectively. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 21760 (227%)

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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at 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 the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
