Compare any two graphics cards:
GeForce GT 420 vs Radeon R7 M265
IntroThe GeForce GT 420 comes with a GPU core clock speed of 700 MHz, and the 2048 MB of GDDR3 RAM is set to run at 900 MHz through a 128-bit bus. It also is made up of 48 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare those specifications to the Radeon R7 M265, which has GPU clock speed of 725 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R7 M265, in theory, should be just a bit faster than the GeForce GT 420 in general. (explain)
Texel RateThe Radeon R7 M265 is a lot (more or less 211%) more effective at AF than the GeForce GT 420. (explain)
Pixel RateThe Radeon R7 M265 should be quite a bit (more or less 107%) more effective at AA than the GeForce GT 420, and also will be able to handle 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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
