Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs Radeon R9 285
IntroThe GeForce 8600 GT 1GB GDDR3 has a core clock speed of 540 MHz and a GDDR3 memory speed of 700 MHz. It also makes use of a 128-bit bus, and uses a 80 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specs to the Radeon R9 285, which uses a 28 nm design. AMD has clocked the core speed at 918 MHz. The GDDR5 memory runs at a speed of 1375 MHz on this specific card. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 285 should be 686% faster than the GeForce 8600 GT 1GB GDDR3 overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 285 will be quite a bit (about 1090%) faster with regards to texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateThe Radeon R9 285 will be a lot (more or less 580%) better at FSAA than the GeForce 8600 GT 1GB GDDR3, and capable of handling higher screen resolutions more effectively. (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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant 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.
