GeForce 8600 GT 512MB GDDR3 vs GeForce GTX Titan

Intro

Compare those specifications to the GeForce GTX Titan, which uses a 28 nm design. nVidia has clocked the core frequency at 837 MHz. The GDDR5 memory works at a speed of 1502 MHz on this card. It features 2688 SPUs along with 224 Texture Address Units and 48 ROPs.

GeForce 8600 GT 512MB GDDR3		8640 Mtexels/sec
	Difference: 178848 (2070%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX Titan is superior to the GeForce 8600 GT 512MB GDDR3, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8600 GT 512MB GDDR3		4320 Mpixels/sec
	Difference: 35856 (830%)

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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
