Radeon HD 5850		128000 MB/sec
	Difference: 51200 (40%)

Texel Rate

The Radeon R7 370 4G should be a little bit (approximately 20%) better at anisotropic filtering than the Radeon HD 5850. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
Radeon HD 5850		52200 Mtexels/sec
	Difference: 10200 (20%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 370 4G is the winner, and very much so. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
Radeon HD 5850		23200 Mpixels/sec
	Difference: 8000 (34%)

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 data (counted in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface 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 card's memory bandwidth, the faster 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 processed 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 higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
