The AMD Radeon R9 Nano Review: The Power of Size

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.

AMD is about to claim bankruptcy......silverblue - Friday, September 11, 2015 - link
Somebody just bought 20% of their shares. If you want them to file chapter 11, be a little more patient, grasshopper.close - Thursday, September 10, 2015 - link
Guess Nvidia is dead to you as a brand also for the whole 3.5GB issue (which we all know how well was handled). That leaves you with the Intel iGPU. But some people have the little fetish of being crapped on from a single direction.Saying "they're dead to me as a brand" is the same as saying "from now on I will disconsider their offerings even if they may be better value or simply better". And this does you no favors, trust me.

Does AMD not give out review guidelines? It seems that's something nvidia does. eg when the Ashes benchmark came out they told review sites not to use AA, a lot didn't. Maybe AMD figures some sites will ignore this guidance. eg. if they said nano was not to be compared to the 980ti or fury X and was a niche product for small cases, some sites like kitguru would still compare it to a 980ti rather than the closest mini GPUgw74 - Thursday, September 10, 2015 - link
It is none of the companies' business how their products are reviewed. Their only business to make good products. Anyone can compare anything they like to anything else and benchmark it using anything they want.ianmills - Thursday, September 10, 2015 - link
I wish it was but even anandtech falls in line with this and overuses company's marketing terms to make it hard to compare to previous generationsRyan Smith - Thursday, September 10, 2015 - link
Interesting. I'm certainly not trying to "fall in line" or otherwise use specific marketing terms, so if I'm doing that then it's unplanned. What terms have I been using, so that I can watch out for it in the future?Alexvrb - Friday, September 11, 2015 - link
Yeah! Tell em gw! Same with automotive testing. No guidelines, no rules! If they loan you a 1-ton pickup truck and you compare it to sports cars on a twisty track, bash the truck and give it a horrible review for "poor handling vs 500K exotic sports cars" - well that's none of their business!/sarcasm

I am talking about no guidelines or rules from the manufacturers, genius. That obviously does not mean the reviewing party does not use its brain to compare and test in a sensible way. You absolute clown.Kutark - Thursday, September 10, 2015 - link
They're not demands, they're just telling people ahead of time if there is a particular game that is exhibiting issues with a particular setting. Which especially if its an in progress issue they're debugging, doesn't paint a good picture of the product, and only serves to give ammunition for detractors to cherry pick data points to use in their crusades.
