Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X should perform a little bit faster than the Radeon HD 6670 (OEM) 1GB overall. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon HD 6670 (OEM) 1GB		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M365X will be much (more or less 93%) faster with regards to AF than the Radeon HD 6670 (OEM) 1GB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 6670 (OEM) 1GB		19200 Mtexels/sec
	Difference: 17800 (93%)

Pixel Rate

The Radeon R9 M365X is quite a bit (more or less 131%) more effective at anti-aliasing than the Radeon HD 6670 (OEM) 1GB, and should be able to handle higher resolutions better. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 6670 (OEM) 1GB		6400 Mpixels/sec
	Difference: 8400 (131%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
