Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs Radeon R5 M255
IntroThe GeForce GTX 260 216SP 55 nm features core clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 216 SPUs along with 72 TAUs and 28 ROPs.Compare that to the Radeon R5 M255, which features GPU clock speed of 940 MHz, and 2048 MB of DDR3 memory running at 1000 MHz through a 64-bit bus. It also features 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce GTX 260 216SP 55 nm should perform a lot faster than the Radeon R5 M255 in general. (explain)
Texel RateThe GeForce GTX 260 216SP 55 nm is much (about 121%) faster with regards to AF than the Radeon R5 M255. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 260 216SP 55 nm is the winner, by a large margin. (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 (counted in MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card can 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 Render Output Units 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
