Radeon HD 4750 vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which comes with core speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X should be quite a bit faster than the Radeon HD 4750 overall. (explain)

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

Texel Rate

The Radeon R9 M365X should be a lot (more or less 58%) faster with regards to anisotropic 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 is much (about 27%) more effective at full screen anti-aliasing than the Radeon HD 4750, and should be capable of handling higher screen resolutions while still performing well. (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 largest amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, 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 the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
