Compare any two graphics cards:
GeForce GT 315 vs Radeon R5 M255
IntroThe GeForce GT 315 features a core clock frequency of 625 MHz and a DDR3 memory speed of 790 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 48 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the Radeon R5 M255, which comes with GPU core speed of 940 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce GT 315 should perform quite a bit faster than the Radeon R5 M255 overall. (explain)
Texel RateThe Radeon R5 M255 should be much (approximately 88%) more effective at anisotropic filtering than the GeForce GT 315. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R5 M255 is superior to the GeForce GT 315, by far. (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 data (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a 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 speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
