Compare any two graphics cards:
Radeon HD 4830 1GB vs Radeon R5 M330
IntroThe Radeon HD 4830 1GB comes with a GPU clock speed of 575 MHz, and the 1024 MB of GDDR4 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 640(128x5) Stream Processors, 32 Texture Address Units, and 16 ROPs.Compare those specs to the Radeon R5 M330, which has 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 HD 4830 1GB should be 300% faster than the Radeon R5 M330 in general, due to its greater data rate. (explain)
Texel RateThe Radeon R5 M330 will be a small bit (more or less 12%) faster with regards to anisotropic filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 4830 1GB is a better choice, but only just. (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 largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
