GeForce 8600 GT 1GB GDDR3 vs Geforce GTX 760

Intro

Compare all of that to the Geforce GTX 760, which comes with core speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1152 SPUs along with 96 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 will be 758% faster than the GeForce 8600 GT 1GB GDDR3 in general, due to its greater 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 quite a bit (approximately 989%) more effective 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 will be a lot (approximately 626%) faster with regards to 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 information (measured in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
