Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs Radeon HD 6870
IntroThe GeForce 8600 GT 1GB GDDR3 has a clock frequency of 540 MHz and a GDDR3 memory speed of 700 MHz. It also features a 128-bit memory bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 6870, which uses a 40 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 memory works at a frequency of 1050 MHz on this particular model. It features 1120 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6870 will be 500% quicker than the GeForce 8600 GT 1GB GDDR3 in general, because of its greater data rate. (explain)
Texel RateThe Radeon HD 6870 should be quite a bit (about 483%) more effective at texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 6870 is superior to the GeForce 8600 GT 1GB GDDR3, and very much so. (explain)
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. Price Comparison

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card 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 number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
