Compare any two graphics cards:
GeForce 9400 GT 256MB vs Radeon R9 M290X
IntroThe GeForce 9400 GT 256MB comes with a core clock speed of 550 MHz and a GDDR2 memory frequency of 400 MHz. It also makes use of a 128-bit memory bus, and makes use of a 65 nm design. It features 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare all that to the Radeon R9 M290X, which uses a 28 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory is set to run at a frequency of 1200 MHz on this specific card. It features 1280 SPUs along with 80 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 M290X should theoretically be a lot superior to the GeForce 9400 GT 256MB in general. (explain)
Texel RateThe Radeon R9 M290X is a lot (approximately 1445%) faster with regards to texture filtering than the GeForce 9400 GT 256MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R9 M290X is the winner, and very much so. (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 (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record 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 the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
