Compare any two graphics cards:
GeForce GTX 580 3GB vs Radeon R7 370 2G
IntroThe GeForce GTX 580 3GB comes with a GPU clock speed of 772 MHz, and the 3072 MB of GDDR5 RAM is set to run at 1002 MHz through a 384-bit bus. It also features 512 Stream Processors, 64 Texture Address Units, and 48 ROPs.Compare those specifications to the Radeon R7 370 2G, which uses a 28 nm design. AMD has clocked the core frequency at 975 MHz. The GDDR5 memory is set to run at a speed of 1400 MHz on this card. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 580 3GB should in theory perform just a bit faster than the Radeon R7 370 2G overall. (explain)
Texel RateThe Radeon R7 370 2G is much (approximately 26%) better at AF than the GeForce GTX 580 3GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 580 3GB is the winner, but it probably won't make a huge difference. (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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
