Radeon HD 6850 vs Radeon RX 560

Intro

The Radeon HD 6850 uses a 40 nm design. AMD has set the core speed at 775 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this card. It features 960 SPUs along with 48 TAUs and 32 ROPs.

Compare those specs to the Radeon RX 560, which features core clock speeds of 1175 MHz on the GPU, and 7000 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Radeon RX 560 114688 MB/sec
Difference: 13312 (12%)

Texel Rate

The Radeon RX 560 should be much (approximately 102%) better at texture filtering than the Radeon HD 6850. (explain)

Radeon RX 560 75200 Mtexels/sec
Radeon HD 6850 37200 Mtexels/sec
Difference: 38000 (102%)

Pixel Rate

The Radeon HD 6850 will be quite a bit (about 32%) more effective at FSAA than the Radeon RX 560, and capable of handling higher resolutions without slowing down too much. (explain)

Radeon HD 6850 24800 Mpixels/sec
Radeon RX 560 18800 Mpixels/sec
Difference: 6000 (32%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
