AMD Radeon R9 Nano Officially Detailed – Features Fiji GPU With 175W TDP, Single 8-Pin Connector and SFF Design That’s Faster Than Hawaii


Yesterday, we got the first look at several Fiji GPU based graphics cards. One of these new cards was the Radeon R9 Nano which was a very small form factor graphics card that was also based on the Fiji GPU. The shockingly little card was a surprise and it took some time for me to digest that this card actually houses the top tier Fiji GPU and the details we have learned from AMD at the event are surprisingly good.

AMD Radeon R9 Nano Detailed - Fiji GPU With 175W Thermal Design and Faster Than Hawaii

We didn't go into many details about the card yesterday but its time to detail it bit by bit. First of all, if you still want to know about the Fiji GPU, you can visit our other post about the chip here. The AMD Radeon R9 NANO is a tiny card, that's what AMD said it themselves. It might be tiny but for a card this small, it has some shocking performance and efficiency numbers. This card is actually based on the same 8.9 Billion transistor boasting Fiji GPU which is featured on the Radeon R9 Fury X and has 4 GB HBM VRAM dedicated for gaming that runs along a 1024-bit wide bus interface clocked at 500 MHz (1 Gbps effective) that pumps out 512 GB/s bandwidth. This card boasts 2.0 times the performance per watt compared to Hawaii and that is just crazy and yes, it is actually faster than Hawaii too, not some numbers AMD is giving out for marketing.

The AMD Radeon R9 Nano is faster than Hawaii and we mean the full fat Hawaii chip featured on the Radeon R9 290X. The proves that AMD has done some crazy work designing this little beast of a card which is just an amazing engineering feat by the team at Red. The other thing is that, the card has a 175W thermal design power and the same goes for typical power usage. AMD has given this card a single 8-Pin power connector to feed power to it. It has 2 times the performance density and is 2 times the performance per watt compared to R9 290X and here is where things get interesting.

AMD Radeon R9 Nano Features 85-90% Performance of Radeon R9 Fury X

AMD actually has a Fiji XT based card and a Fiji Pro based cards. We have the specifications down in the table which you can see for comparison. Those cards are also rated with a 275W TDP while the Radeon R9 Nano, also a Fiji based card is 175W. The reason it is so efficient has to do with two things and those include a significantly cut down Fiji GPU along with lower clock speeds. Even with those in place, the card is still faster than the 290 and 390 series that are based on Hawaii GPU. In fact, AMD confirmed to us that the Radeon R9 Nano is about 85-90% of Radeon R9 Fury X (in terms of performance). We still don't know as to how much extent is the card disabled since the card has a launch slated for later in summer, this year, but I can guess that the card may be priced around the $449-$499 US range.

There's reason to believe so, the AMD Radeon R9 390X which features the Hawaii XT (Grenada XT) core is said to be slower than the Radeon R9 Nano. The Radeon R9 390X is priced at $429 US at the moment so it will be a bad decision to release the card at a lower price than 390X. The $449 Us and $499 US spots actually sound a lot better since it offers better performance than R9 390X and even comes close to the Radeon R9 Fury X, then it will be an interesting offering in the consumer market. Do note that this is just speculation and the card may even end up priced lower than my guesses here.

The last bit about the card is the thermal solution itself. The single fan air cooler confirms that the card can actually be clocked lower to make room for smaller PCB and cooler designs. The R9 Fury X uses liquid cooling while the R9 Fury is said to feature a triple fan air cooler. Display outputs include three Display Ports and a single HDMI display connector. The card is expected to launch in Summer 2015.
