GeForce GTX 470 PhysX 

Investigation determined the culprit to be the beta BIOS on their ASRock Z170 Extreme7+, specifically the BIOS which allowed you to overclock locked Intel CPUs.

We retested our RX 470 to account for this issue, and we also updated our review with DirectX 12 benchmarks for Rise of the Tomb Raider and Hitman, plus full OpenGL and Vulkan benchmarks for Doom.

Sapphire is using Black Diamond 4 chokes and a 4+1 power phase design that is driven by a single 8-pin PCI-E power connector (and up to 75W from the motherboard slot).

Out of the box this cooler should keep the RX 470 GPU running cooler and quieter than the RX 480, but it should also enable users to get higher clocks out of the smaller GPU (less cores means less heat and more overclocking headroom assuming you get a good chip from the silicon lottery).

It looks better, performs faster, and has a far superior cooler.

In the case of the Radeon RX 470, AMD is expecting that most (if not all) of its board partners will be using their own custom coolers.

Polaris-based graphics cards are coming next week, and the leaks are starting to appear online.
