Power consumption in factory state as summary
The 23.7 watts at idle have improved, but are still quite high, fluctuating between 12 watts and up to 33 watts. With a second monitor, this quickly becomes 50 watts and more (peaks over 68 watts). The driver still urgently needs to be improved here, especially since the PCIe does not always clock down correctly and fully. By the way, we can see very nicely that the full TBP is not even exhausted in Ultra-HD and the torture loop once again increases up to the cap (I’ll come to that in a moment). AMD’s new implementation of telemetry for the entire card has a strong limiting effect here, even though the value is of course immensely high. I had already discussed this in several articles and AMD also communicated it like this.
Load distribution between PCIe slot and PCIe sockets
The distribution of the power supply shows that the card has hardly any reserves, concerning the TBP and the performance of the rails. While the three 8-pin connectors are not yet fully utilized, the mainboard slot is only just below the allowed 5.5 amps with up to 5.3 amps in the stress test. In gaming, this is all still just below 5 amps.
All in all, AMD has almost fully utilized the load distribution on the PEG here, which is actually a bit irritating. While NVIDIA has almost completely stopped supplying via the PEG, AMD uses this rail quite excessively. In this context, the new partial voltage VDDCR_USR also raises some questions. However, no tangible information about it is tangible in the board partners’ documents either. The up to 20 watts that AMD only provides via the two phases there are slightly surprising, because a single voltage regulator would probably have been more than sufficient for that.
