Radeon HD 6950 vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which uses a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 6950 is 122% quicker than the Radeon R9 M365X in general, because of its greater data rate. (explain)

Radeon HD 6950		160000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 88000 (122%)

Texel Rate

The Radeon HD 6950 should be much (about 90%) more effective at AF than the Radeon R9 M365X. (explain)

Radeon HD 6950		70400 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 33400 (90%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 6950 is the winner, and very much so. (explain)

Radeon HD 6950		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 maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one 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 the texel rate, the better the video 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 maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
