Radeon HD 6950 vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which uses a 14 nm design. AMD has clocked the core speed at 926 MHz. The GDDR5 memory runs at a frequency of 1650 MHz on this particular card. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Texel Rate

The Radeon RX 470 should be quite a bit (approximately 68%) more effective at AF 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 a better choice, but not by far. (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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
