Compare any two graphics cards:
GeForce 940M vs Radeon HD 5450
IntroThe GeForce 940M features a GPU clock speed of 1072 MHz, and the 2048 MB of DDR3 memory is set to run at 1000 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.Compare that to the Radeon HD 5450, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM works at a frequency of 800 MHz on this particular model. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 940M should in theory perform quite a bit faster than the Radeon HD 5450 in general. (explain)
Texel RateThe GeForce 940M will be much (about 395%) better at anisotropic filtering than the Radeon HD 5450. (explain)
Pixel RateThe GeForce 940M is quite a bit (about 230%) better at FSAA than the Radeon HD 5450, and also able to handle higher screen resolutions without losing too much performance. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
