Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X will be 41% faster than the Radeon HD 4750 in general, because of its higher data rate. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon HD 4750		51200 MB/sec
	Difference: 20800 (41%)

Texel Rate

The Radeon R9 M365X is quite a bit (approximately 58%) better at texture filtering than the Radeon HD 4750. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 4750		23360 Mtexels/sec
	Difference: 13640 (58%)

Pixel Rate

The Radeon R9 M365X should be quite a bit (approximately 27%) faster with regards to full screen anti-aliasing than the Radeon HD 4750, and also capable of handling higher resolutions better. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 4750		11680 Mpixels/sec
	Difference: 3120 (27%)

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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its 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 clock 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
