Radeon HD 6850 vs Radeon RX 570
Intro
The Radeon HD 6850 uses a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific card. It features 960 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.Compare all of that to the Radeon RX 570, which uses a 14 nm design. AMD has clocked the core speed at 1168 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.

Comments
One Response to “Radeon HD 6850 vs Radeon RX 570”rx570's configured with the 8 pin power connector Can run if a 6 pin is used instead. no where does it say this anywhere. you just cannot over clock it. infact down clocking it 5% to stay safe. and no stress testing other wise it works.
