Sapphire took its time, which certainly did not harm the whole project. While some competitors have already scattered PVT samples, i.e. the small series, among the media before the start of the actual mass production, S... Board layout
Sapphire differs significantly from AMD's reference design when designing the board. This even makes sense in many places, as the cooling has been optimized and is in the foreground. Due to the elimination of the external spokes... Important preliminary remark
In some games we were able to register the phenomenon that the nominally faster Sapphire RX Vega64 Nitro+ fell behind the reference card of the RX Vega. However, that this is not a measurement error or even ... Results in WQHD (2560 x 1440 Pixel)
Breathe in sapphires, because the much cooler card now (as expected) not only has the reference card fully under control, but also scores above all with the frame times and thus also the minimum frame rates. You... Results in WQHD (2560 x 1440 Pixel)
Although Destiny 2 is actually a DirectX-11-based game, which should be more the GeForce cards, AMD's Vega cards can stand up to their GeForce competitors. The Sapphire RX V... Results in WQHD (2560 x 1440 Pixel)
Now the picture returns, because the Sapphire card is slightly slowed down (obviously by the driver), which makes it just behind the reference card. But you don't have the GeForce cards... Results in WQHD (2560 x 1440 Pixel)
Doom and Volcano are not anything that could shake the RX Vega64. Here, the Sapphire RX Vega64 Nitro+ is again, as expected, in front of the nominally weaker reference card, although not quite as clear as... Results in WQHD (2560 x 1440 Pixel)
Even if the RX Vega64 has to be sorted just behind Nvidia's GeForce GTX 1080, the hierarchy within the AMD guild remains consistent. The Sapphire card is in front of the reference model, if only breathless... Results in WQHD (2560 x 1440 Pixel)
All three interesting cards are in fact equal, with the Sapphire card surprisingly pulling the shortest in this trio. Driver optimizations shouldn't really come into play here ... Results in WQHD (2560 x 1440 Pixel)
If one had to name a prime example of the advantage of a board partner card, then this game, at least in WQHD, would probably be a really good candidate. Despite DirectX11, you have the GeForce GTX 10...results in WQHD (2560 x 1440 pixels)
All relevant cards are very close together, with the Sapphire RX Vega64 Nitro+ leading the upper-middle-class trio as expected. However, the lead is very close.

Power consumption at different loads
The power consumption in the gaming loop is at the measured approx. 327 watts well above the 300 watt mark and thus also above what was measured in the reference model. For this, there is the more constant performance with acceptable noise, so at least something. Power comes from power consumption and on the chip itself Sapphire can't change anything. Only in the general conditions up to cooling, voltages and power limit.
The corresponding voltages for both loops in the factory state are shown in the following diagram:
Compliance with the standard on the motherboard slot
With a maximum of 2.7 amps (torture), the card is still just 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, 2 amperes are much further below, as is the maximum overclocking. Overall, the balancing has been implemented in an exemplary manner 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 388 watts, however, you can live well, because they occur only very briefly.
The flowing currents behave in an equivalent way:
If the power limit is set to the maximum value, the power consumption increases again by approx. 60 watts on average, which of course also translates into the curve. It is now up to 421 watts as a peak, because every modern power supply should be able to iron out easily. These short-term peaks need to be known, but not overestimated. Good hardware provided.
Here, too, the currents reach up to 33 amperes, but actually you could have saved the third 8-pin connection, because you are only just above the norm, if at all.
In the stress test, the short-term peaks are significantly lower, even if the power consumption is again slightly higher than for gaming.
Even now, the flowing currents follow the curve and show no abnormalities.
