Compare any two graphics cards:
GeForce GTX 275 vs Radeon R9 M265X
IntroThe GeForce GTX 275 makes use of a 55 nm design. nVidia has clocked the core speed at 633 MHz. The GDDR3 RAM is set to run at a speed of 1134 MHz on this specific model. It features 240 SPUs along with 80 Texture Address Units and 28 Rasterization Operator Units.Compare that to the Radeon R9 M265X, which uses a 28 nm design. AMD has clocked the core speed at 575 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the GeForce GTX 275 should in theory be quite a bit better than the Radeon R9 M265X overall. (explain)
Texel RateThe GeForce GTX 275 should be a lot (about 120%) faster with regards to anisotropic filtering than the Radeon R9 M265X. (explain)
Pixel RateThe GeForce GTX 275 will be quite a bit (approximately 93%) better at FSAA than the Radeon R9 M265X, and also will 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 max amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the 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 graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
