Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon R5 M255
IntroThe GeForce GTS 250 512MB comes with a clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit memory bus, and makes use of a 65/55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon R5 M255, which uses a 28 nm design. AMD has clocked the core speed at 940 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this specific card. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTS 250 512MB should theoretically be much faster than the Radeon R5 M255 in general. (explain)
Texel RateThe GeForce GTS 250 512MB is quite a bit (more or less 151%) more effective at anisotropic filtering than the Radeon R5 M255. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTS 250 512MB is superior to the Radeon R5 M255, 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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 can be applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
