Compare any two graphics cards:
GeForce GTX 660 vs Radeon R9 M295X
IntroThe GeForce GTX 660 uses a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this model. It features 960 SPUs as well as 80 Texture Address Units and 24 Rasterization Operator Units.Compare those specifications to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 memory is set to run at a speed of 1375 MHz on this specific model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 M295X is 22% faster than the GeForce GTX 660 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon R9 M295X should be a lot (more or less 22%) more effective at texture filtering than the GeForce GTX 660. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M295X 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
