Compare any two graphics cards:
Radeon HD 4550 512MB vs Radeon R5 M330
IntroThe Radeon HD 4550 512MB uses a 55 nm design. AMD has set the core speed at 600 MHz. The GDDR3 RAM works at a frequency of 800 MHz on this particular model. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.Compare all that to the Radeon R5 M330, which has core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R5 M330 is 13% faster than the Radeon HD 4550 512MB overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon R5 M330 is a lot (approximately 329%) more effective at texture filtering than the Radeon HD 4550 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R5 M330 is superior to the Radeon HD 4550 512MB, 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 max amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at 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 that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 reach the maximum fill rate.
