Compare any two graphics cards:
Geforce GTX 680 vs Radeon R9 M275X
IntroThe Geforce GTX 680 features a clock frequency of 1006 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It features 1536 SPUs, 128 TAUs, and 32 ROPs.Compare those specs to the Radeon R9 M275X, which comes with GPU clock speed of 900 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Geforce GTX 680 should theoretically be quite a bit faster than the Radeon R9 M275X overall. (explain)
Texel RateThe Geforce GTX 680 will be a lot (approximately 258%) faster with regards to anisotropic filtering than the Radeon R9 M275X. (explain)
Pixel RateThe Geforce GTX 680 is a lot (about 124%) faster with regards to anti-aliasing than the Radeon R9 M275X, and also will be capable of handling higher screen resolutions without slowing down too much. (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 (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
