Radeon HD 6950 2GB vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which has GPU clock speed of 925 MHz, and 4096 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 6950 2GB is 122% quicker than the Radeon R9 M365X in general, because of its greater data rate. (explain)

Radeon HD 6950 2GB		160000 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 88000 (122%)

Texel Rate

The Radeon HD 6950 2GB should be a lot (approximately 90%) better at AF than the Radeon R9 M365X. (explain)

Radeon HD 6950 2GB		70400 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 33400 (90%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 6950 2GB is the winner, by far. (explain)

Radeon HD 6950 2GB		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 largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at 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 write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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.
