Compare any two graphics cards:
GeForce GTX 295 vs Radeon R9 280
IntroThe GeForce GTX 295 makes use of a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM works at a speed of 999 MHz on this specific model. It features 240 SPUs as well as 80 TAUs and 28 Rasterization Operator Units.Compare all of that to the Radeon R9 280, which has a clock speed of 933 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 280 should in theory perform a little bit faster than the GeForce GTX 295 in general. (explain)
Texel RateThe Radeon R9 280 should be a little bit (about 13%) more effective at anisotropic filtering than the GeForce GTX 295. (explain)
Pixel RateThe GeForce GTX 295 should be a little bit (more or less 8%) faster with regards to full screen anti-aliasing than the Radeon R9 280, and also should be capable of handling higher 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. 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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
