Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs Radeon R9 280
IntroThe GeForce 8600 GT 1GB GDDR3 has a GPU core speed of 540 MHz, and the 1024 MB of GDDR3 memory is set to run at 700 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare all that to the Radeon R9 280, which comes with a core clock speed of 933 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 384-bit memory bus, and uses a 28 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R9 280 should perform a lot faster than the GeForce 8600 GT 1GB GDDR3 in general. (explain)
Texel RateThe Radeon R9 280 should be a lot (about 1109%) faster with regards to texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateThe Radeon R9 280 should be much (approximately 591%) more effective at AA than the GeForce 8600 GT 1GB GDDR3, and also should be capable of handling higher screen resolutions better. (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

Display 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 one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 get to the maximum fill rate.
