Compare any two graphics cards:
GeForce GT 310 vs Radeon R9 280X
IntroThe GeForce GT 310 makes use of a 40 nm design. nVidia has set the core frequency at 589 MHz. The DDR2 RAM is set to run at a speed of 1000 MHz on this specific model. It features 16 SPUs along with 8 TAUs and 4 ROPs.Compare that to the Radeon R9 280X, which comes with a core clock speed of 850 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 384-bit bus, and uses a 28 nm design. It features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 280X should perform a lot faster than the GeForce GT 310 overall. (explain)
Texel RateThe Radeon R9 280X should be a lot (approximately 2209%) faster with regards to texture filtering than the GeForce GT 310. (explain)
Pixel RateThe Radeon R9 280X is a lot (approximately 1054%) more effective at AA than the GeForce GT 310, and will be capable of handling higher resolutions more effectively. (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 information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
