Updated: Nvidia GeForce GTX 1070 8GB Pascal Review

Partner Cards And Efficiency Testing

A number of custom GeForce GTX 1070 board and cooling designs are now available (at least to back-order; supply of Pascal-based hardware remains sparse overall). So, we’re pitting a few different cards against each other. First, we have Nvidia's GeForce GTX 1070 and 1080 Founders Edition. Then there's MSI's GeForce GTX 1070 and 1080 Gaming X 8G. The last card we're using to compare is MSI's GeForce GTX 980 Ti Lightning, powered by the Maxwell architecture.

Relationship Between Clock Frequency, Power Consumption & Performance

Although we're running a great many tests, the work is worthwhile in order to determine each card's efficiency. This process involves measuring power consumption in steps across a wide range of clock rates, then comparing that information to gaming performance. By the end, we'll know whether overclocking or dialing back power are worth pursuing. We're also comparing Maxwell and Pascal to each other after correcting for clock rate, which should shed some light on the performance of each CUDA core and how they interact with the GPU's other subsystems.

It goes without saying that the next logical step after a detailed analysis of power consumption is a deeper dive into temperature and noise. But before detailing our setup and methodology, let's take a quick look at the technical specifications of all five graphics cards:

Test Methodology & Benchmark Selection

In order to maintain as close to real-world conditions as possible, we ran all of our tests in a closed Nanoxia Deep Silence 5 chassis. Its stock fans were set to spin as slowly as possible in the front and at their medium setting in the back.

Power consumption is measured according to the processes outlined in The Math Behind GPU Power Consumption And PSUs. Positioning the current probes proved a bit of a challenge this time, but we made it work.

Power Consumption
Test Method
Contact-free DC Measurement at PCIe Slot (Using a Riser Card)
Contact-free DC Measurement at External Auxiliary Power Supply Cable
Direct Voltage Measurement at Power Supply
Test Equipment
2 x Rohde & Schwarz HMO 3054, 500 MHz Digital Multi-Channel Oscilloscope with Storage Function
4 x Rohde & Schwarz HZO50 Current Probe (1 mA - 30 A, 100 kHz, DC)
4 x Rohde & Schwarz HZ355 (10:1 Probes, 500 MHz)
1 x Rohde & Schwarz HMC 8012 Digital Multimeter with Storage Function
1 x Optris PI640 80Hz Infrared Camera + PI Connect

The next challenge was choosing a benchmark. Because we'd need to run so many data points, we could only pick one test to use. Even then, collecting all of the information we needed took almost six full work days.

We tried to be as representative as possible. To this end, we performed a number of preliminary tests and, based on their results, ended up choosing Metro: Last Light at Ultra HD resolution. This allowed us to run the graphics cards at full load without running into CPU or memory bottlenecks, meaning we're looking at the worst-case scenario for graphics card power consumption without causing GPU Boost to pull clock rates lower.

As a foundation for our platform, we used a Core i7-6700K processor running at 4.5 GHz under an all-in-one liquid cooler. This way, we made sure that the rest of the system wasn’t going to negatively influence our test results.

Happyware Crossover Workstation
Test System
Core i7-6700K @ 4.5 GHz
2x 8 GB DDR4-3400
Asus P10 WS
2x Samsung SM863 (3D V-NAND)
Seagate Constellation Server HDD
Windows 10 Enterprise (TH2, All Updates)
Driver
GeForce 368.39

    Fury X is going for $399-449 as of yesterday on Newegg.

    So given the simultaneously lower price and higher performance of the partner boards, only an actual idiot would buy the "Founder's Edition" GTX 1070?

    I feel that I should regret getting MSI 1070 FE. MSI's custom designs perform superior then FE cards in every way. Very impressive. Asus and Gigabyte's custom designs must also do better than FE cards.

    When you're talking about the heat on FE cards. I think the default fan speed is 45-50% at 83c. Make it 80% and the card never reaches 70c even with boost clock up to 1900+. What speeds are the MSI fans running at during your temp measurements?

    Edit: The article has been updated, so I deleted my original comment about the MSI GPU.

    "This means that the lowest possible GPU Boost clock rate step gets eliminated from the bottom of the BIOS’ table. So, if you want an additional space at the top, you need to make room for it by getting rid of the very bottom one."

    If it were me, I would have removed a low to middle clock rate instead of the very lowest to get both the low idle power consumption and the OC speed.

    Still annoyed that they posted this review without including the 970 as a baseline.

    Regarding the possible audible noise because of power spikes on PEG: it is not really about cheap MB, but about using analog audio out of MB, and not anything digital, right?
    Also, about overclocking: I think reviews of all these new generation nVidia and AMD cards should include average clock that cards operated when doing all game benchmarks. Official boost clock numbers are a bit useless, because AMD cards run games at below boost clocks, and average for nVidia GTX1070 is above boost clocks. Having just official boost clock numbers make it difficult to evaluate overclocking potential and make real gains look much bigger or smaller than expected.

    Am I the only one that noticed that the Founder's Edition cards managed to pull over 75 watts from the motherboard PCIe slot and that no one went bonkers over it?

    It has narrow peaks that go over 75 W, as have a number of cards in the past. For the most part, what people were concerned about with the RX 480 was that average power was over 75 W. Whether that concern was warranted... well that's another question.

    The last page needs to be updated as well.
    "Missing out on power consumption, operating temperatures and noise due to the constraints of Computex leaves us with an incomplete picture of GeForce GTX 1070, though we can certainly make some assumptions."
    You added those pages.

    I don't see why people bought the Founder's Edition. This is just proof how much better aftermarket coolers are.

    Looking forward to reviews of 3rd party cards from other vendors.

    Yep, and that's why I am poking fun at it.

    Yeah the same could be said about anything. An aftermarket GTX 1080 reaches 400W. But that's only a rare thin spike.

    The GTX 1070 Founder Edition averages 75 watts but realistically has a 65 watt limit.

    That doesn't make any sense.

    From page 7 of the review:

    "Taking a closer look at the motherboard slot yields a surprising finding: none of the cards in this round-up use the 3V rail at all. This means that the PCIe slot doesn’t really provide the 75W most enthusiasts assume it does, since the 12V rail only offers about 65W on its own."

    That is about the PCIe spec at 12V, not the power usage of cards in the test.
