Overclocking

As NVIDIA is pushing the GTX 1070 Ti for overclocking, it is only fair that we look into it. While NVIDIA does support overclocking, they have limited actual overvolting, and instead providing the ability to unlock 1-2 more boost bins and associated voltages. Using Precision XOC, we adjusted the core and memory clocks, as well as the power/temperature limit and percent 'overvoltage.' For the 180W GTX 1070 Ti, the TDP and TDP limit match the GTX 1080, resulting in a 120% power limit (216W). The 1.093v boost voltage is no surprise, matching the GTX 1080 and 1070 FEs.

GTX 1070 Ti FE Overclocking
  Stock Overclocked
Core Clock 1607MHz 1787MHz
Boost Clock 1683MHz 1863MHz
Max Boost Clock 1898MHz 2078MHz
Memory Clock 8Gbps 8.8Gbps
Max Voltage 1.062v 1.093v

The results, of course, cannot be taken as representative of all GTX 1070 Ti Founders Editions, as this is only a sampled sample size of one. But results here can offer some insight. For one, if there were explicit actual overvolting, it seems very possible to stabilize ~2100+MHz clocks on the GTX 1070 Ti Founders Edition. At any rate, GPU overclocks topped out with observed clocks in the high 2000MHz region, roughly 10% over the previously measured average in-game clockspeeds. Memory overclocks were only able to go up 200MHz from the base 2002MHz, or also about 10%. All-in-all, very similar to the GTX 1070 FE, which also managed 10% overclocks on both GPU and GDDR5 memory. Recalling that the GTX 1070 Ti FE clocked on average just 2% higher than the GTX 1070 FE at stock, there's nothing particularly groundbreaking here, especially considering the 20-25% overclock capability of Maxwell 2 reference cards.

A total of four different overclocks were tested. First was a baseline, consisting of 100% overvoltage and max power/temperature limits. The second was overclocking the GDDR5 memory by 800Mbps. The third was overclocking the GPU with a +180MHz offset; in practice this resulted in observed clocks between 2030 - 2080MHz. Lastly, all previous adjustments were combined for an overall overclock.

Although this is more of a cursory look than anything else, the combined overclock provides the best performance, just like it was for the GTX 1080 and 1070, although it seems like memory overclocking is more effective on the GTX 1070 Ti. Earlier, we mentioned how the GTX 1070 Ti compared to the GTX 1070 by having four more SMs but without any additional memory bandwidth, and perhaps that is playing a role here.

There isn't much to add on the power, temperature, and noise front. Understandably, the card will heat up a few more degrees and spin its blower faster, at the expense of ~25W at the wall, inasmuch as the 120% power limit will let it. As a casual overclocker, there may not be a lot to gain here; the GTX 1070 Ti FE already boosts to ~1800+MHz at stock, and squeezing 200MHz more with the anemic capabilities of NVIDIA's reference PCB won't make waves. And for hardcore overclockers, there would be little need of the reference board's power delivery system.

    Still think it's a bit expensive Reply

    Agreed. This should be 1070 price, 1070 down to the 970's original MSRP... Anything less is gouging. Reply

    I think it should cost $20. Reply

    This mining rush might kill the pc gaming industry, when a gamer cannot find a single high performance card at msrp prices, they will just flock to the xbox one x or ps4 pro, this is outrageous. Reply

    Hey everyone, please watch your language. (not you specifically, Spunjji, I removed a comment below you) Reply

    I think that any comment whining about prices should be removed ASAP. Reply

    I'm not a gamer so I'm more wide eyed at a the idea of a video card that draws 80 watts at idle and over 300 under load...more than my whole system under load. And upwards of $500? Wow. I guess I'm sort of glad I'm not a gamer. :) Reply

    Those are total system numbers, not the card itself. Reply
  • CaedenV - Thursday, November 2, 2017 - link

    The card by itself idles at ~20W and load at ~250W

    Still quite a bit compared to a small desktop or a laptop though lol

    Yup, those power numbers are terrible. The desire for improvement in visual quality and competition between the two remaining dGPU manufactures has certainly done us no favors when it comes to electrical consumption and waste heat generation in modern PCs. Sadly, people often forget that good graphics don't automatically imply tons of fun will be had at the keyboard and they consequently create demand that causes a positive feedback loop that make 200+ watt TDP GPUs viable products. I remember the many hours I killed playing games on my Palm IIIxe and it needed a new pair of AAA batteries once every 3 or so weeks. Not everyone feels that way though and for an obviously large number of consumer buyers, graphics and resolution mean the world to them no matter the price of entry or the power consumption. Reply
