Memory Bandwidth

As far as performance goes, the Radeon RX 470 should in theory be quite a bit superior to the Radeon HD 6950 overall. (explain)

Radeon RX 470		211200 MB/sec
Radeon HD 6950		160000 MB/sec
	Difference: 51200 (32%)

Texel Rate

The Radeon RX 470 is much (more or less 68%) faster with regards to anisotropic filtering than the Radeon HD 6950. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon HD 6950		70400 Mtexels/sec
	Difference: 48128 (68%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 470 is superior to the Radeon HD 6950, but it probably won't make a huge difference. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon HD 6950		25600 Mpixels/sec
	Difference: 4032 (16%)

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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, 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 maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
