Compare any two graphics cards:
GeForce GT 320 vs Radeon R9 M280X
IntroThe GeForce GT 320 makes use of a 40 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 memory works at a speed of 790 MHz on this specific model. It features 72 SPUs as well as 24 Texture Address Units and 8 ROPs.Compare that to the Radeon R9 M280X, which comes with GPU core speed of 900 MHz, and 4096 MB of GDDR5 memory running at 1375 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 M280X should theoretically be much better than the GeForce GT 320 in general. (explain)
Texel RateThe Radeon R9 M280X is much (more or less 289%) better at anisotropic filtering than the GeForce GT 320. (explain)
Pixel RateThe Radeon R9 M280X should be a lot (about 233%) more effective at full screen anti-aliasing than the GeForce GT 320, and will be capable of handling 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: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This 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 a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
