GeForce 8500 GT vs Geforce GTX 760

Intro

Compare those specs to the Geforce GTX 760, which comes with a GPU core clock speed of 980 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 256-bit bus. It also is made up of 1152 Stream Processors, 96 Texture Address Units, and 32 ROPs.

GeForce 8500 GT		12800 MB/sec
	Difference: 179456 (1402%)

Texel Rate

The Geforce GTX 760 is much (about 2513%) more effective at texture filtering than the GeForce 8500 GT. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 90480 (2513%)

Pixel Rate

If running with a high resolution is important to you, then the Geforce GTX 760 is the winner, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 29560 (1642%)

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 information (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
