Radeon HD 7950 vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which has a core clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7950 should be a lot faster than the Radeon R9 M365X in general. (explain)

Radeon HD 7950		240000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 168000 (233%)

Texel Rate

The Radeon HD 7950 will be quite a bit (about 142%) more effective at texture filtering than the Radeon R9 M365X. (explain)

Radeon HD 7950		89600 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 52600 (142%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 7950 is a better choice, by far. (explain)

Radeon HD 7950		25600 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 10800 (73%)

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 data (counted in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
