AMD Radeon R9 Nano : the best GPU mining card ?

Last june, a great news for us GPU miners was announced at the last PC Gaming Show in Los Angeles. AMD, the main GPU cards provider for efficient non-ASIC mining just introduced what could be a game changer : the Radeon R9 Nano. Let’s review the reasons why this card is a potential winner.

AMD Radeon R9 Nano energy consumption

Energy efficiency

When it comes to building a mining rig, the first thing to be concerned about will be the power it will consume compared to the revenues projection. AMD announced that a single Radeon R9 Nano will require only 175 watts to operate at full throttle (based on the thermal design, which is adapted to the board consumption). This represents only 53% of the energy – and the cost – of what a typical Radeon R9 290X demands. This also means that a single 1200W PSU could be enough to feed a full 6-cards rig.

Amazing performances

We still have to wait to see the board in action, but despite the fact that AMD still used a 28 nanometers chip architecture to build this new generation of cards (and will probably skip a 20 nanometers design to jump directly to 14 nanometers in 2016) the brand new chip onboard, code named ‘Fiji’, is impressively said to be ‘significantly faster’ than AMD previous ‘Hawaii’ architecture, which equipped the best mining rigs so far with Radeon R9 290X or 390X cards. If the comparaison of FP32 raw compute power with these cards shows almost a 30% increase in favor of the R9 Nano, we still have to test it to see how it behaves with integers calculations, used for mining.

Underclocking potential

We don’t know yet the underclocking benefits that could be obtained with this particular card. However, some indications shows that the Fiji architecture allows a drastic power consumption reduction that does not sacrifice performances much (9% throughput reduction should be able to reduce the energy costs by 40%).
Sadly, AMD will not allow you to change the memory clock yet, the HBC memory used in the Nano card seems ‘too new’ to be tweaked without potential hazardous reactions. However, when it comes to mining, the memory clock may not be the most important setting, and the R9 Nano’s core clock will remain adjustable.

Small size

It's small !The AMD Radeon R9 Nano is will only be six inches long, which could be really handy for the optimum board positioning and thermal management. For mining rigs operating inside an oil bath for example (oils such as the Novec 7xxx series) this also means less oil to buy/use.
