Reason instead of obesity: Gigabyte RX Vega64 Gaming OC in test

If there were enough Vega chips and thus a wide range of cards, the Gigabyte RX Vega64 in this form would probably be the ideal entry-level card, rather than a top-of-the-line model.

Power consumption at different loads

The power consumption in the gaming loop is at the measured approx. 261 watts in Balanced Mode about 20 watts below what could be measured at the reference in the default BIOS. This is all the more astonishing because the performance is even a tick higher. So the BIOS change and the new power table seem to be working. The power consumption, at almost the same cycle, corresponds roughly to the values of the smaller RV Vega56 Gaming OC, which is something to be called.

The manual OC mode with a 50% higher power limit then shoots well beyond the 330 watt mark, whereby the cooler already looks overwhelmed in these performance regions, if you do not push the fans at the same time. For this reason, we have also dispensed with overclocking in the further course and only use the balanced mode without additional surcharges.

The corresponding voltages for both loops in the factory state are shown in the diagram below, whereby the control fury around the power limit has increased sharply.

Compliance with the standard on the motherboard slot

With a maximum of 2.4 amps (torture), the card is well below half of what the PCI SIG sets with a maximum of 5.5 amps (66 watts) for the 12 volt rail on the motherboard slot. In the Gaming Loop, you're much further below that with just 1.9 amperes. Overall, the balancing has been implemented very exemplary and the mainboard lot is hardly seriously burdened.

Detailed graphics: power consumption and currents

For better illustration, we have also recorded all measurement results as detailed curves in the graphs below. Naturally, the power consumption peaks in gaming are the most important. With peaks of up to 340 watts, however, you can live well, because they occur only very briefly.
