Compare any two graphics cards:
GeForce GT 130 vs Radeon R9 M265X
IntroThe GeForce GT 130 has a clock frequency of 500 MHz and a DDR2 memory frequency of 250 MHz. It also uses a 192-bit memory bus, and makes use of a 55 nm design. It is made up of 48 SPUs, 24 Texture Address Units, and 16 ROPs.Compare all that to the Radeon R9 M265X, which comes with a clock frequency of 575 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 M265X will be 500% quicker than the GeForce GT 130 overall, due to its higher data rate. (explain)
Texel RateThe Radeon R9 M265X is quite a bit (more or less 92%) more effective at anisotropic filtering than the GeForce GT 130. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 M265X is a better choice, but only just. (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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
