The Radeon R9 M370X will be a lot (about 199%) faster with regards to anisotropic filtering than the Radeon HD 3850 1GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 3850 1GB		10688 Mtexels/sec
	Difference: 21312 (199%)

Pixel Rate

The Radeon R9 M370X is a small bit (more or less 20%) better at full screen anti-aliasing than the Radeon HD 3850 1GB, and able to handle higher screen resolutions better. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 3850 1GB		10688 Mpixels/sec
	Difference: 2112 (20%)

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 largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
