The Radeon R9 M380 is a lot (about 59%) faster with regards to anisotropic filtering than the Radeon HD 5750 512MB. (explain)

Radeon R9 M380		40000 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 14800 (59%)

Pixel Rate

The Radeon R9 M380 will be much (more or less 43%) faster with regards to FSAA than the Radeon HD 5750 512MB, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M380		16000 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 4800 (43%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
