Compare any two graphics cards:
GeForce 8600 GT 1GB DDR2 vs Radeon R5 M255
IntroThe GeForce 8600 GT 1GB DDR2 comes with clock speeds of 540 MHz on the GPU, and 400 MHz on the 1024 MB of DDR2 RAM. It features 32 SPUs along with 16 TAUs and 8 ROPs.Compare those specs to the Radeon R5 M255, which features a clock speed of 940 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R5 M255 should perform a lot faster than the GeForce 8600 GT 1GB DDR2 in general. (explain)
Texel RateThe Radeon R5 M255 will be a lot (more or less 118%) better at texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateThe Radeon R5 M255 should be much (about 74%) more effective at AA than the GeForce 8600 GT 1GB DDR2, and also will be able to handle higher 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 (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
