GeForce 8500 GT vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which features core speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs as well as 56 TAUs and 32 ROPs.

GeForce 8500 GT		45 Watts
GeForce GTX 560		150 Watts
	Difference: 105 Watts (233%)

Memory Bandwidth

In theory, the GeForce GTX 560 should be quite a bit faster than the GeForce 8500 GT overall. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 115328 (901%)

Texel Rate

The GeForce GTX 560 will be quite a bit (approximately 1160%) better at AF than the GeForce 8500 GT. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 41760 (1160%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 560 is a better choice, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 24120 (1340%)

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 across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
