Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon R9 M385X
IntroThe GeForce GT 220 GDDR3 makes use of a 40 nm design. nVidia has clocked the core speed at 625 MHz. The GDDR3 memory works at a frequency of 1012 MHz on this particular card. It features 48 SPUs along with 16 Texture Address Units and 8 ROPs.Compare those specifications to the Radeon R9 M385X, which uses a 28 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 memory is set to run at a speed of 1500 MHz on this specific card. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M385X is 196% quicker than the GeForce GT 220 GDDR3 overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 M385X should be quite a bit (more or less 516%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 M385X is the winner, by a large margin. (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

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
