Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5770 is 7% faster than the Radeon R9 M365X overall, due to its higher data rate. (explain)

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

Texel Rate

The Radeon R9 M365X should 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 will be a little bit (about 9%) better at FSAA than the Radeon HD 5770, and should be able to handle 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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
