XFX Radeon RX 5700 DD Ultra 8GB GDDR6 Video Card Review

Videocards/VGA Reviews by stefan @ 2019-10-10

With the DD Ultra we are seeing a notable performance increase over the previously tested PowerColor Red Dragon RX 5700 and at the same time the power limits have been upped from 173W to about 206W (maximum recorded ASIC Power consumption). This modification did also imply higher Boost clocks, up to 1934MHz (much higher than the advertised speed) so with the XFX RX 5700 DD Ultra we did experience quite a performance jump. XFX also made sure to include a beefy cooling system to go with it so the card will function under optimal conditions even with a raised TGP.

Both 100mm fans get power from the same black header:

The cooling system shares similarities in design with the RAW II Ultra, but the heatpipe arrangement is different near the frontal area of the card:

The GPU plate is cooled by four individual heatpipes, while the memory is cooled via an aluminum interposer and thermal pads:

The aluminum heatsink component for the VRM does use another, larger thermal pad as an interface:

Here are some additional shots of the cooling system, in more detail:
