Nvidia GeForce RTX 2070 Super in review - the more reasonable RTX 2080 in small and cheaper? | Page 11

The fact that the RTX 2070 is being upgraded is one thing, because this card hasnot sold so badly. The other thing is the GeForce RTX 2070 Super, which wants to scratch the RTX 2080, which in turn, according to the distributors and the board partner, does not really want to be sold - at least as far as the expected quantities are concerned. Price and performance are only one facet, because this card somehow lacked the target group. For Ultra-HD usually too slow and for QHD often far too expensive, because there is already a GeForce RTX 2070 can tidy up properly.

Power consumption and loads

The 10 watts in the idle are very good. However, the almost 227 watts in the stress test and the nearly 229 watts in the gaming loop are significantly higher than the power target of 215 watts set in the BIOS from the factory, for whatever reason. Because the maximum value for overclocking with 260 watts in gaming is again exactly what the BIOS specifies as the maximum power limit. With the torture loop, however, it is again 11 watts more. Since the BIOS specifications are otherwise always so meticulously adhered to, the question really arises here as to the technical reason. Component tolerances?

Here is a short excerpt from what Nvidia gave this card in the firmware of limits:

The voltages are in the expected range, with the oc's permissible board power being the limiting factor, not the voltage. One notices very clearly that Nvidia deliberately limits here and that the thermal influence of the cooling is also clearly visible.

The load distribution on the rails is perfect, because in normal operation and in the CASE of the OC, the maximum permissible 5.5 amperes of the motherboard slot are never exceeded. Balancing has been really good here.

Power supply design and peak loads/currents

As I have already demonstrated in detail in my basic article "The fight of graphics card against power supply – power consumption and load peaks demystified", there are also temporarily higher loads in the millisecond range, which are unfavorable in case of unfavorable designed or improperly equipped power supplies can already lead to unexplained shutdowns. The TBP (Typical Board Power) measured by the graphics card manufacturer or the reviewers does not really help for a stable design of the system.

Peaks with intervals between 1 and 10 ms can lead to shutdowns with very fast-reacting protective circuits (OPP, OCP), especially for multi-rail power supplies, although the average power consumption is still in the norm. For the GeForce RTX 2070 Super I would therefore calculate with more than 300 watts to have enough reserves in case of a case. A short excerpt with high resolution now show us the 20 ms intervals, how I run them automatically for valuation:

Detailed recording of average power consumption and flowing currents

As usual, I now also set aside the power consumption and the flowing currents as detailed graphics of my oscillograph measurements. A service that hardly anyone else offers and which shows how the maps "tick" in detail:
