Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X should be 150% faster than the Radeon HD 6570 (OEM) 1GB in general, due to its higher bandwidth. (explain)

Radeon R9 M375X		72000 MB/sec
Radeon HD 6570 (OEM) 1GB		28800 MB/sec
	Difference: 43200 (150%)

Texel Rate

The Radeon R9 M375X is a lot (more or less 160%) more effective at texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
	Difference: 25000 (160%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375X is superior to the Radeon HD 6570 (OEM) 1GB, by a large margin. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon HD 6570 (OEM) 1GB		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 max amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This 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 that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
