Compare any two graphics cards:
GeForce GTX 580 vs Radeon R9 390 8G
IntroThe GeForce GTX 580 uses a 40 nm design. nVidia has set the core speed at 772 MHz. The GDDR5 RAM works at a speed of 1002 MHz on this model. It features 512 SPUs along with 64 TAUs and 48 ROPs.Compare those specs to the Radeon R9 390 8G, which uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 RAM runs at a frequency of 1500 MHz on this particular model. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 390 8G should in theory be a lot superior to the GeForce GTX 580 overall. (explain)
Texel RateThe Radeon R9 390 8G should be much (approximately 224%) better at texture filtering than the GeForce GTX 580. (explain)
Pixel RateThe Radeon R9 390 8G should be a lot (about 73%) better at anti-aliasing than the GeForce GTX 580, and should be able to handle higher resolutions without losing too much performance. (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 largest amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total 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 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 can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
