Compare any two graphics cards:
Radeon HD 5970 vs Radeon R9 280X
IntroThe Radeon HD 5970 uses a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific card. It features 1600 SPUs along with 160 TAUs and 64 Rasterization Operator Units.Compare all that to the Radeon R9 280X, which makes use of a 28 nm design. AMD has set the core speed at 850 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 280X, in theory, should perform just a bit faster than the Radeon HD 5970 overall. (explain)
Texel RateThe Radeon HD 5970 is much (approximately 113%) faster with regards to anisotropic filtering than the Radeon R9 280X. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 5970 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number 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 processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that 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 amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
