Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs Radeon R9 270
IntroThe GeForce 8600 GT 1GB GDDR3 features a GPU core clock 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 features 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the Radeon R9 270, which makes use of a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 RAM works at a speed of 1400 MHz on this model. It features 1280 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 270 should theoretically be quite a bit faster than the GeForce 8600 GT 1GB GDDR3 in general. (explain)
Texel RateThe Radeon R9 270 should be a lot (approximately 733%) better at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 270 is a better choice, by far. (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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
