Compare any two graphics cards:
GeForce 9400 GT 256MB vs Radeon R5 M255
IntroThe GeForce 9400 GT 256MB makes use of a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR2 memory is set to run at a frequency of 400 MHz on this card. It features 16 SPUs as well as 8 Texture Address Units and 4 ROPs.Compare those specs to the Radeon R5 M255, which comes with core clock speeds of 940 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R5 M255 should be 25% quicker than the GeForce 9400 GT 256MB overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon R5 M255 should be a lot (about 327%) more effective at anisotropic filtering than the GeForce 9400 GT 256MB. (explain)
Pixel RateThe Radeon R5 M255 should be quite a bit (about 242%) better at anti-aliasing than the GeForce 9400 GT 256MB, and also able to handle higher resolutions without slowing down too much. (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 (measured in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
