Compare any two graphics cards:
GeForce GTX 260 vs Radeon R5 M255
IntroThe GeForce GTX 260 has a clock frequency of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also features a 448-bit memory bus, and makes use of a 65 nm design. It is comprised of 192 SPUs, 64 TAUs, and 28 ROPs.Compare those specifications to the Radeon R5 M255, which makes use of a 28 nm design. AMD has set the core speed at 940 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this specific model. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GTX 260 should perform a lot faster than the Radeon R5 M255 in general. (explain)
Texel RateThe GeForce GTX 260 will be much (approximately 96%) faster with regards to anisotropic filtering than the Radeon R5 M255. (explain)
Pixel RateThe GeForce GTX 260 will be much (about 114%) faster with regards to full screen anti-aliasing than the Radeon R5 M255, and will be capable of handling higher screen resolutions better. (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 max amount of information (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
