Compare any two graphics cards:
GeForce GTX 580 3GB vs Radeon R9 380 2G
IntroThe GeForce GTX 580 3GB uses a 40 nm design. nVidia has clocked 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 Texture Address Units and 48 ROPs.Compare those specifications to the Radeon R9 380 2G, which has a core clock speed of 970 MHz and a GDDR5 memory frequency of 1425 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 580 3GB should perform a bit faster than the Radeon R9 380 2G in general. (explain)
Texel RateThe Radeon R9 380 2G is a lot (approximately 120%) faster with regards to anisotropic filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 580 3GB is a better choice, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units 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 applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record 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 card's clock speed. 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
