Compare any two graphics cards:
GeForce GTX 260 vs Radeon R9 M385X
IntroThe GeForce GTX 260 has core clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 192 SPUs as well as 64 Texture Address Units and 28 Rasterization Operator Units.Compare that to the Radeon R9 M385X, which has a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the GeForce GTX 260 should in theory be a bit better than the Radeon R9 M385X in general. (explain)
Texel RateThe Radeon R9 M385X will be a lot (approximately 67%) more effective at anisotropic filtering than the GeForce GTX 260. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 M385X is a better choice, 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video 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 card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
