Radeon HD 5570		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon R9 M375 should be quite a bit (about 212%) better at anisotropic filtering than the Radeon HD 5570. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 27600 (212%)

Pixel Rate

The Radeon R9 M375 is much (more or less 212%) more effective at FSAA than the Radeon HD 5570, and able to handle higher screen resolutions while still performing well. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 11040 (212%)

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: Bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock 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 bandwidth is, the lower the potential to get to the maximum fill rate.
