Sapphire Radeon RX 6800 XT Nitro+ in the test - It also goes quietly, quickly and quite thirsty | Page 5

Let’s start with both BIOSes with the individual loads and the resulting power consumption. The almost 14 watts in idle go to read from the microcontroller and LED light chain, the rest is as usual in the gradation. Now let’s compare both BIOSes, because we see that the BIOS 2 doesn’t have to stay at 320 watts, but reaches up to 350 watts with the BIOS 2. this is not only what AMD allows the board partners as maximum, but also what I had already calculated months ago based on the board partner BIOS.

The card with the BIOS 2 is much more economical because it works closer to the sweet spot. 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 the sensor values output by GPU-Z, for example. Specifications and real values are in reality always 2 pairs of shoes. Even if you leave the Wattman at 1.15 volts or even tweak it to 1.25 volts, the VDDC_GFX is limited to 1.15 volts anyway and as a default value is never even reached, no matter what you set. As a comparison, I have included the reference card as a basis and especially the comparison of the SoC voltage is worthwhile.

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 exactly 2.8 amps are reached under normal load, which is absolutely exemplary. This also applies to the up to 3.2 amps at BIOS 1 and maximum load, because there is still a lot of room left.
