Radeon HD 7850 vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has clocked the core frequency at 925 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 7850 should theoretically be quite a bit better than the Radeon R9 M365X in general. (explain)

Radeon HD 7850		153600 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 81600 (113%)

Texel Rate

The Radeon HD 7850 is quite a bit (about 49%) more effective at texture filtering than the Radeon R9 M365X. (explain)

Radeon HD 7850		55040 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 18040 (49%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 7850 is the winner, by far. (explain)

Radeon HD 7850		27520 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 12720 (86%)

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 data (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be applied per second. This number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a 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 - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
