Is AMD getting the crown back? Radeon RX 6900 XT 16 GB review with benchmarks and a deeper technical analysis

Let’s start with the individual loads and the respective resulting power consumption of both new Radeon cards. The Radeon RX 6900 XT is well in the race with 10 to 11 watts in idle, whereby about a good 7 watts are allotted to the external PCIe connections and about 4 watts to the motherboard. In gaming you exceed the maximum advertised 300 watts with just under 304 watts and if you use the Wattman’s offered OC possibilities, it’s even more. Especially in the partial load ranges, however, it is only just above the RX 6800 XT.

With external tools you can also reach up to almost 350 watts, but the performance doesn’t scale with the supplied power. The normal user will never reach this level anyway, because exactly this part above 300 watts is then again the responsibility of the board partners.As a special service I have also recorded the respective individual voltages VDDCR_GFX, VDDCR_SOC and VDDCI_MEM, since these values differ significantly from what e.g. GPU-Z outputs as averaged sensor value. Specifications and real values are in reality always 2 pairs of shoes.

Compliance with standards at the motherboard slot (PEG)

Let’s now move on to the load on the motherboard slot, whose load is specified by the PCI SIG as 5.5 amps. This results in a maximum power of 66 watts at 12 volts. You can see very clearly that under full load exactly 2.8 amps are reached and even with the maximum power limit only 2.9 amps, which is absolutely exemplary.
