The NVIDIA GeForce GTX 980 Review: Maxwell Mark 2
by Ryan Smith on September 18, 2014 10:30 PM ESTThe Test
For the launch of GTX 980 we are using NVIDIA’s press beta drivers for the card, release 334.07 beta. This is the first (semi) public release of the R343 driver set, and coinciding with the release of the Maxwell 2 architecture it also marks the end of support for NVIDIA’s D3D10 GPUs: the 8, 9, 100, 200, and 300 series. Beginning with R343 these products are no longer supported in new driver branches and have been moved to legacy status.
Meanwhile as noted earlier, due to time constraints and hardware problems today we are focusing our coverage on the GTX 980. Next week we will be looking at GTX 980 SLI (hint: it’s fast) and GTX 970.
And on a testing note, as is standard for our reviews we are using our reference Radeon R9 290X for our 290X benchmarks. For this reason we are including both the standard and uber modes for the sake of clarity and completeness. The temperature throttling that the reference 290X suffers from is basically limited to just the reference 290X, as the non-reference/custom models use open air coolers that have no problem dissipating the 290X’s full heat load. Both modes are included for this reason, to demonstrate how a reference 290X performs and how a custom model would perform. At this point you can still buy reference 290X cards, but the vast majority of retail cards will be of the non-reference variety, where the 290X Uber mode’s results will be more applicable.

Look at "Load Power Consuption — Furmark" test. It's 80W lower with 980 than with 780Ti.Carrier - Friday, September 19, 2014 - link
Yes, but the 980's clock is significantly lowered for the FurMark test, down to 923MHz. The TDP should be fairly measured at speeds at which games actually run, 1150-1225MHz, because that is the amount of heat that we need to account for when cooling the system.Ryan Smith - Friday, September 19, 2014 - link
It doesn't really matter what the clockspeed is. The card is gated by both power and temperature. It can never draw more than its TDP.FurMark is a pure TDP test. All NVIDIA cards will reach 100% TDP, making it a good way to compare their various TDPs.

If that is the case, then the charts are misleading. GTX 680 has a 195W TDP vs. GTX 770's 230W (going by Wikipedia), but the 680 uses 10W more in the FurMark test.I eagerly await your GTX 970 report. Other sites say that it barely saves 5W compared to the GTX 980, even after they correct for factory overclock. Or maybe power measurements at the wall aren't meant to be scrutinized so closely :)

To follow up: in your GTX 770 review from May 2013, you measured the 680 at 332W in FurMark, and the 770 at 383W in FurMark. Those numbers seem more plausible.Ryan Smith - Saturday, September 20, 2014 - link
680 is a bit different because it's a GPU Boost 1.0 card. 2.0 included the hard TDP and did away with separate power targets. Actually what you'll see is that GTX 680 wants to draw 115% TDP with NVIDIA's current driver set under FurMark.Carrier - Saturday, September 20, 2014 - link
Thank you for the clarification.wanderer27 - Friday, September 19, 2014 - link
Power at the wall (AC) is going to be different than power at the GPU - which is coming from the DC PSU.There are loses and efficiency difference in converting from AC to DC (PSU), plus a little wiggle from MB and so forth.

As stated in the article, the power figures are total system power draw. The GTX980 is throwing out nearly double the FPS of the GTX680, so this is causing the rest of the system (mostly the CPU) to work harder to feed the card. This in tun drives the total system power consumption up, despite the fact the GTX980 itself is drawing less power than the GTX680.
