Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X, in theory, should be quite a bit faster than the Radeon HD 4750 in general. (explain)

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

Texel Rate

The Radeon R9 M365X should be quite a bit (more or less 58%) more effective 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 much (more or less 27%) more effective at AA than the Radeon HD 4750, and also capable of handling higher resolutions without losing too much performance. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could 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 speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
