Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M385X is 233% quicker than the Radeon HD 6570 (OEM) 1GB overall, because of its higher data rate. (explain)

Radeon R9 M385X		96000 MB/sec
Radeon HD 6570 (OEM) 1GB		28800 MB/sec
	Difference: 67200 (233%)

Texel Rate

The Radeon R9 M385X should be much (more or less 295%) faster with regards to AF than the Radeon HD 6570 (OEM) 1GB. (explain)

Radeon R9 M385X		61600 Mtexels/sec
Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
	Difference: 46000 (295%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M385X is a better choice, and very much so. (explain)

Radeon R9 M385X		17600 Mpixels/sec
Radeon HD 6570 (OEM) 1GB		5200 Mpixels/sec
	Difference: 12400 (238%)

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 (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses 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 texture map elements (texels) that can be applied per second. This number is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
