Compare any two graphics cards:
GeForce 920M vs Radeon HD 5550
IntroThe GeForce 920M uses a 28 nm design. nVidia has set the core speed at 954 MHz. The DDR3 memory works at a speed of 900 MHz on this particular card. It features 384 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare all of that to the Radeon HD 5550, which has core clock speeds of 550 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 320(64x5) SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the GeForce 920M should theoretically be a small bit better than the Radeon HD 5550 overall. (explain)
Texel RateThe GeForce 920M should be quite a bit (approximately 247%) faster with regards to texture filtering than the Radeon HD 5550. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 920M is superior to the Radeon HD 5550, 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 (in units of MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once 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 AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could 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 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
