Compare any two graphics cards:
GeForce GT 440 3GB vs Radeon R9 M265X
IntroThe GeForce GT 440 3GB makes use of a 40 nm design. nVidia has set the core frequency at 594 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this particular model. It features 144 SPUs as well as 24 Texture Address Units and 24 Rasterization Operator Units.Compare all of that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has clocked the core speed at 575 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 M265X is 67% quicker than the GeForce GT 440 3GB overall, due to its greater data rate. (explain)
Texel RateThe Radeon R9 M265X should be much (approximately 61%) more effective at anisotropic filtering than the GeForce GT 440 3GB. (explain)
Pixel RateThe GeForce GT 440 3GB will be a lot (approximately 55%) better at FSAA than the Radeon R9 M265X, and also should be able to handle higher screen resolutions better. (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 transferred across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock 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 applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
