It has been just over two months since AMD released its newest Navi-based GPU, the RX 5600 XT. Since then it feels like the world has been flipped upside down, but we are continuing our coverage of this GPU with a look at our fourth partner card. This model is the ASRock Phantom Gaming D3, where the D3 signifies this is a triple-fan cooler. A more compact ‘D2' model is also available, with – yep, you guessed it! – a dual-fan cooler.
ASRock is still a relative new-comer to the GPU space, and the RX 5600 XT Phantom Gaming D3 is only the third Navi-based GPU we have seen from the company – the others being the RX 5700 XT Taichi X OC+, as well as the more modest RX 5500 XT Challenger 8GB. Offering a triple-fan cooler, a thick heatsink and some relatively simple RGB lighting, how does this 5600 XT compare to the likes of the Sapphire Pulse and Gigabyte Gaming OC?

Original BIOS spec, left, compared with updated BIOS spec, right.
As with most 5600 XTs on the market, the Phantom Gaming D3 has received a BIOS update tweaking its core and memory speeds. Initially it looked like ASRock was going to follow MSI's stance and not update the memory speed on its cards, however just this week a new public BIOS landed pushing memory speeds to 14Gbps. This was the BIOS used for all testing and I had no issues with system stability while testing the card.
For the rest of the spec, 5600 XT uses the same 36 Compute Unit, Navi 10 GPU as the RX 5700, meaning a total of 2304 stream processors. Even with the updated BIOS, however, memory bandwidth for the RX 5600 XT is still less than the RX 5700 (336GB/s compared to 448GB/s) as the 5600 XT uses a 192-bit memory interface, compared to the 256-bit interface used by the 5700.
