Let’s start with the individual loads and the resulting power consumption for both BIOSes. The ample 10 watts in idle are alright without a fan, the rest is as usual in the gradation. If we now compare both BIOSes, we see that it reaches up to over 356 watts with BIOS 2. Well, torture test and water cooling. Gaming is a little more economical.
By the way, the card with BIOS 1 is a bit more economical because it works closer to the sweet spot. You can see this also at the voltages As a special service I also recorded the respective single voltages VDDCR_GFX, VDDCR_SOC and VDDCI_MEM, because these values differ significantly from what e.g. GPU-Z outputs as sensor value. Specifications and real values are always 2 pairs of shoes in reality. The VDDC_GFX is limited to 1.175 volts anyway and will never be exceeded as a default value, no matter what you set it to.
Standard compliance at the motherboard slot (PEG)
Now let’s look at the load of the motherboard slot, which is specified by the PCI SIG with 5.5 Amps. This results in a maximum power of 66 watts at 12 volts. You can see very clearly that under normal load exactly 2.8 amps are reached, 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 leeway left here.
