GeForce 8500 GT vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which uses a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 memory is set to run at a speed of 1001 MHz on this specific card. It features 336 SPUs as well as 56 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce GTX 560, in theory, should perform quite a bit faster than the GeForce 8500 GT in general. (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 (about 1160%) better at texture filtering than the GeForce 8500 GT. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 560 is the winner, and very much so. (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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
