The custom Radeon RX 5700s are on their way! After MSI teased its RX 5700 Mech series, it’s now Asrock’s turn to take a spin at AIB Navi hardware with the ASRock Challenger RX 5700 and 5700 XT.

One of the biggest problems with the Navi parts was the terrible reference design. We’ve seen the blower-style GPU cooler before in reference AMD models–from Polaris to Vega–and it’s performed terribly every time. The same goes for reference Navi parts: our 5700 and 5700XT review units ran hot with the fans ramped up and this played a crucial role in limiting these parts’ OC potential.

ASRock’s Challenger series appears set to rectify the flaws of the reference design. These parts will feature a dual-fan design with 10cm blades and a 4-pipe copper heatsink for maximum heat dissipation. The cards feature an aluminum backplate for that extra dose of refinement.

Asrock is keeping things conservative when it comes to clock speeds. The RX 5700XT Challenger has a 1795 MHz Game Clock out of the box–this is just 40 MHz higher than the reference model but keeping in mind the trouble reviewers have had with overclocking Navi, we’re quite excited to see a factory OC’d product–it’ll hopefully be less temperamental. ASRock has gone easy on the memory–in fact, they haven’t touched it and the GDDR6 modules run at the stock 15 Gbps. The RX 5700 (non-XT) Challenger cranks the Game clock up a bit further–we’re looking at a 50 MHz bump to 1675 Mhz. Otherwise, it’s much the same as it’s higher-end stablemate.

This is essentially a soft launch of the Navi board partner cards and while we haven’t seen retail units of the Challenger series pop up yet, we most certainly will in the days to come. Watch this space!
