The AMD Radeon R9 Nano Review: The Power of Size
by Ryan Smith on September 10, 2015 8:00 AM ESTOverclocking
Finally, no review of a high-end video card would be complete without a look at overclocking performance.
Of all of the Fiji cards overclocking the R9 Nano is perhaps the easiest and certainly the most unusual. Due to the fact that the card is essentially a 1000MHz Fiji card with a heavy power throttle, the card is already validated for clockspeeds that under load it doesn’t have the available power to reach. As a result while one can crank up the clockspeeds, the card isn’t going to move until you increase the power limit. And even then you are more likely to hit the power cap again than you are to break 1000MHz sustained. So overclocking the GPU is something of an academic affair.
Radeon R9 Fury/Nano Series Overclocking | |||||
Ref. R9 Fury X | ASUS R9 Fury | Ref. R9 Nano | |||
Boost Clock | 1125MHz | 1075MHz | 1075MHz | ||
Memory Clock | 1Gbps (500MHz DDR) | 1.1Gbps (550MHz DDR) | 1.1Gbps (550MHz DDR) | ||
Power Limit | 100% | 115% | 135% | ||
Max Voltage | 1.212v | 1.169v | 1.2v |
Overall we were able to overclock our sample to 1075MHz on the GPU and 550MHz (1.1Gbps) on the memory. However load clockspeeds were almost always under 1000MHz even with a generous 35% increase in the power target. Overdrive does allow for a larger increase – up to 50% – but with the R9 Nano featuring a less robust power delivery system designed to push less power than R9 Fury or R9 Fury X, we’re hesitant to increase the limit further without a better idea of what the card can safely sustain for extended periods of time.
The overall performance gains from overclocking aren’t huge, but at 7-10% they also aren’t too shabby. However since higher clockspeeds quickly ramp up the power requirements due to the higher voltages required, the performance gains won’t be anywhere near the 35% increase in the power limit, despite that we are in fact still power limited.
Meanwhile the 35% increase in the power limit has a definite knock-on effect on the cooling system. The R9 Nano’s cooler is able to keep up with the additional load, holding temperatures to 74C, but noise levels are now over 51dB(A). Power consumption at the wall is similarly affected, with the R9 Nano essentially giving up all of its energy efficiency gains in the process.

The only thing wrong with the Nano and the rest of the Fury lineup is the price. They should all have debuted $50 cheaper than they did.theNiZer - Thursday, September 10, 2015 - link
My thoughts exactly :)HisDivineOrder - Thursday, September 10, 2015 - link
Nice to see that Anandtech didn't mind getting their card with whatever promises they had to make to get it. I'm reminded of the AMD Red section that this site once had and I begin to wonder if that payment scheme ever really ended or just went "underground?"garbagedisposal - Thursday, September 10, 2015 - link
Jesus Christ, you are one especially rabid and unpleasant person. Please don't comment on this website.Oxford Guy - Thursday, September 10, 2015 - link
If you think this site is pro-AMD you clearly don't read the reviews, like the review of Broadwell that included like 8 slow APUs and not a single FX chip at a reasonable clockspeed (like 4.5 GHz), even though FX, not APUs, offers the best desktop performance from AMD.Creig - Thursday, September 10, 2015 - link
Looks like we have a new generation of Wounded [H] Children on our hands.Will Robinson - Thursday, September 10, 2015 - link
Seeing that Tech Report's Graphics forum used to be sponsored by Nvidia....I guess it went to the same place hmm?eanazag - Tuesday, September 22, 2015 - link
I want one, but not at that price. They need a version of the nano at $300-50 that smacks the 970 mini from cheek to cheek. Though with the whole Fiji series I am disappointed it maxes out at 4 GB of VRAM.Anyhow, I would be interested in the best performance a vendor could offer in a single slot cooler. Not the usual duds that come with a single slot cooler. Ooorrrrr okay performance with a water cooler, when I say okay performance I'm thinking what usually comes in at the $180+-$225 price range.

As someone who is currently heavily invested in Nvidia tech, I would just like to say well done to AMD, this a great (little) product!980 nano please :)

Probably not a 980 Nano, but a 1080 Nano is more likely. This is the future of GPUs. Next year we get FinFET and HBM2 from NVIDIA and ATI. It's only a matter of time before both AMD and NVIDIA have full lineups of SFF GPUs. Why pay more for all that PCB space if you don't need it?
