GeForce 8600 GT 1GB GDDR3 vs GeForce GTX 980 Ti

Intro

Compare those specifications to the GeForce GTX 980 Ti, which uses a 28 nm design. nVidia has set the core speed at 1000 MHz. The GDDR5 memory works at a speed of 1750 MHz on this particular card. It features 2816 SPUs as well as 176 Texture Address Units and 96 Rasterization Operator Units.

Pixel Rate

The GeForce GTX 980 Ti will be quite a bit (approximately 2122%) faster with regards to AA than the GeForce 8600 GT 1GB GDDR3, and able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 91680 (2122%)

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 (in units of megabytes 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 its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 in one second. This figure is worked out by multiplying the total texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
