Compare any two graphics cards:
GeForce GT 130 vs Radeon R9 M270X
IntroThe GeForce GT 130 features a GPU core clock speed of 500 MHz, and the 768 MB of DDR2 RAM runs at 250 MHz through a 192-bit bus. It also is made up of 48 SPUs, 24 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon R9 M270X, which comes with core speeds of 725 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the Radeon R9 M270X should perform quite a bit faster than the GeForce GT 130 overall. (explain)
Texel RateThe Radeon R9 M270X should be quite a bit (more or less 142%) faster with regards to texture filtering than the GeForce GT 130. (explain)
Pixel RateThe Radeon R9 M270X will be much (about 45%) more effective at full screen anti-aliasing than the GeForce GT 130, 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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
