Compare any two graphics cards:
Radeon HD 4650 512MB vs Radeon R5 M330
IntroThe Radeon HD 4650 512MB has core clock speeds of 600 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 RAM. It features 320(64x5) SPUs as well as 32 TAUs and 8 ROPs.Compare those specs to the Radeon R5 M330, which has a clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 320 SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 4650 512MB should be 11% quicker than the Radeon R5 M330 in general, due to its greater data rate. (explain)
Texel RateThe Radeon R5 M330 is a small bit (approximately 7%) more effective at AF than the Radeon HD 4650 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R5 M330 is the winner, by far. (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 (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
