Radeon HD 6950 2GB vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which comes with core speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs as well as 64 TAUs and 16 ROPs.

Radeon RX 560		114688 MB/sec
	Difference: 45312 (40%)

Texel Rate

The Radeon RX 560 should be a bit (approximately 7%) more effective at texture filtering than the Radeon HD 6950 2GB. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 6950 2GB		70400 Mtexels/sec
	Difference: 4800 (7%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6950 2GB is a better choice, and very much so. (explain)

Radeon HD 6950 2GB		25600 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 6800 (36%)

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 information (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
