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.
