GeForce 8600 GT 512MB DDR2 vs GeForce GTX 1080

Intro

Compare all that to the GeForce GTX 1080, which makes use of a 16 nm design. nVidia has clocked the core frequency at 1607 MHz. The GDDR5X RAM works at a speed of 1251 MHz on this specific model. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

GeForce GTX 1080		257120 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 248480 (2876%)

Pixel Rate

The GeForce GTX 1080 will be much (approximately 2281%) faster with regards to FSAA than the GeForce 8600 GT 512MB DDR2, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1080		102848 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 98528 (2281%)

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 information (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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