GeForce 8600 GT 1GB GDDR3 vs Geforce GTX 760

Intro

Compare all that to the Geforce GTX 760, which has GPU core speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also features 1152 Stream Processors, 96 Texture Address Units, and 32 ROPs.

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

Memory Bandwidth

Performance-wise, the Geforce GTX 760 should theoretically be a lot better than the GeForce 8600 GT 1GB GDDR3 overall. (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 quite a bit (more or less 989%) better at texture filtering 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

The Geforce GTX 760 is much (approximately 626%) more effective at anti-aliasing than the GeForce 8600 GT 1GB GDDR3, and should be capable of handling higher screen resolutions without losing too much performance. (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 (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, 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 the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of 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 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 get to the max fill rate.
