Compare any two graphics cards:
GeForce 8400 GS 512MB vs Radeon R9 M290X
IntroThe GeForce 8400 GS 512MB comes with a core clock frequency of 650 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 64-bit bus, and uses a 80 nm design. It is comprised of 16 SPUs, 8 TAUs, and 4 ROPs.Compare those specs to the Radeon R9 M290X, which comes with a GPU core clock speed of 850 MHz, and 4096 MB of GDDR5 RAM running at 1200 MHz through a 256-bit bus. It also features 1280 Stream Processors, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M290X, in theory, should be a lot faster than the GeForce 8400 GS 512MB overall. (explain)
Texel RateThe Radeon R9 M290X should be a lot (approximately 1208%) more effective at anisotropic filtering than the GeForce 8400 GS 512MB. (explain)
Pixel RateThe Radeon R9 M290X should be much (approximately 946%) better at full screen anti-aliasing than the GeForce 8400 GS 512MB, and should be capable of handling 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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video 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 number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
