Compare any two graphics cards:
GeForce GTX 590 vs Radeon HD 5770
IntroThe GeForce GTX 590 features a core clock speed of 607 MHz and a GDDR5 memory speed of 855 MHz. It also makes use of a 384-bit bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 TAUs, and 48 ROPs.Compare all that to the Radeon HD 5770, which comes with a clock frequency of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 590 should in theory be a lot better than the Radeon HD 5770 in general. (explain)
Texel RateThe GeForce GTX 590 is a lot (more or less 129%) faster with regards to AF than the Radeon HD 5770. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 590 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the 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 one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
