Compare any two graphics cards:
GeForce GTX 965M vs Radeon HD 4550 256MB
IntroThe GeForce GTX 965M comes with a clock speed of 944 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It features 1024 SPUs, 64 Texture Address Units, and 32 ROPs.Compare all that to the Radeon HD 4550 256MB, which has a GPU core clock speed of 600 MHz, and 256 MB of DDR3 memory running at 800 MHz through a 64-bit bus. It also is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 965M should be 400% quicker than the Radeon HD 4550 256MB overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 965M should be quite a bit (approximately 1159%) faster with regards to anisotropic filtering than the Radeon HD 4550 256MB. (explain)
Pixel RateThe GeForce GTX 965M is a lot (more or less 1159%) better at FSAA than the Radeon HD 4550 256MB, and should be able to handle higher resolutions better. (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 data (measured in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video 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 video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
