Radeon HD 3690/3830 26496 MB/sec
Radeon R5 M330 14400 MB/sec
Difference: 12096 (84%)

Texel Rate

The Radeon R5 M330 will be quite a bit (more or less 93%) faster with regards to anisotropic filtering than the Radeon HD 3690/3830. (explain)

Radeon R5 M330 20600 Mtexels/sec
Radeon HD 3690/3830 10688 Mtexels/sec
Difference: 9912 (93%)

Pixel Rate

The Radeon HD 3690/3830 will be quite a bit (more or less 30%) faster with regards to FSAA than the Radeon R5 M330, and will be able to handle higher resolutions better. (explain)

Radeon HD 3690/3830 10688 Mpixels/sec
Radeon R5 M330 8240 Mpixels/sec
Difference: 2448 (30%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
