GeForce 8600 GT 1GB GDDR3 vs Geforce GTX 760

Intro

Compare that to the Geforce GTX 760, which has a core clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1152 SPUs, 96 TAUs, and 32 ROPs.

GeForce 8600 GT 1GB GDDR3		47 Watts
Geforce GTX 760		170 Watts
	Difference: 123 Watts (262%)

Memory Bandwidth

In theory, the Geforce GTX 760 should be 758% faster than the GeForce 8600 GT 1GB GDDR3 overall, due to its higher data rate. (explain)

Geforce GTX 760		192256 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 169856 (758%)

Texel Rate

The Geforce GTX 760 will be a lot (approximately 989%) faster with regards to AF than the GeForce 8600 GT 1GB GDDR3. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 85440 (989%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 760 is a better choice, by far. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 27040 (626%)

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 max amount of data (counted in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
