Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X will be 13% faster than the Radeon HD 6570 (OEM) 2GB overall, due to its greater data rate. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 6570 (OEM) 2GB		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X should be much (approximately 105%) more effective at texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
	Difference: 16400 (105%)

Pixel Rate

The Radeon R9 M370X will be much (more or less 146%) more effective at AA than the Radeon HD 6570 (OEM) 2GB, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
	Difference: 7600 (146%)

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 data (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
