Compare any two graphics cards:
GeForce GTX 295 vs Radeon R9 270
IntroThe GeForce GTX 295 uses a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory runs at a speed of 999 MHz on this specific card. It features 240 SPUs as well as 80 Texture Address Units and 28 ROPs.Compare those specs to the Radeon R9 270, which has GPU clock speed of 900 MHz, and 2048 MB of GDDR5 memory set to run at 1400 MHz through a 256-bit bus. It also is made up of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 295 should theoretically be quite a bit better than the Radeon R9 270 in general. (explain)
Texel RateThe GeForce GTX 295 is a lot (more or less 28%) faster with regards to anisotropic filtering than the Radeon R9 270. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 295 is the winner, not by a very large margin though. (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 transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum 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 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 most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
