Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5770 should be 7% quicker than the Radeon R9 M365X overall, due to its greater data rate. (explain)

Radeon HD 5770		76800 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 4800 (7%)

Texel Rate

The Radeon R9 M365X will be a bit (more or less 9%) more effective at AF than the Radeon HD 5770. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 5770		34000 Mtexels/sec
	Difference: 3000 (9%)

Pixel Rate

The Radeon R9 M365X should be a bit (approximately 9%) faster with regards to AA than the Radeon HD 5770, and capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 5770		13600 Mpixels/sec
	Difference: 1200 (9%)

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 megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 calculated by multiplying the total amount of texture units 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 maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
