Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon R9 M290X
IntroThe GeForce GT 340 1GB features a core clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the Radeon R9 M290X, which makes use of a 28 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory is set to run at a speed of 1200 MHz on this particular model. It features 1280 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M290X, in theory, should be quite a bit faster than the GeForce GT 340 1GB overall. (explain)
Texel RateThe Radeon R9 M290X is much (more or less 286%) better at AF than the GeForce GT 340 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M290X is a better choice, 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 maximum amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
