AMD R9 Nano specification leaked - has 4096 GPU cores

The specifications for AMD's R9 "Fury" Nano have just been leaked, confirming that this GPU will be using a full Fiji GPU core with 4096 GCN GPU cores.

This GPU manages to have a TDP of 100w lower than AMD's Fury X GPU, which uses the same number of GPU cores, but the Fury X does so at a higher clock speed. The R9 Nano will be AMD's most efficient GPU yet, having 2x the performance per watt of AMD's previous flagship, the R9 290X, and used the new HBM memory technology to allow this GPU to be created in a tiny form factor.

AMD's R9 Fury GPU has recently been pictured, showing that that the GPU will be powered by a single rear facing 8-pin PCIe power connector and that the GPU has a 4 phase power delivery solution and is taken up almost entirely by the main GPU die.

This GPU truely shows the benefits of AMD's HBM memory, as before now a GPU of this size was impossible for a GPU with this amount of VRAM and a DIE of this size. The space savings allowed by HBM have allowed AMD to make this card only 16cm long, which is pretty mch the same size as a PCIe slot.

When AMD announced the R9 Fury Nano GPU, we found it to be one of the most interesting GPUs AMD had shown at their E3 Live conference. This GPU will reportedly be releasing on August 27th and will be the most efficient GPU we have seen on AMD CPUs yet, with HBM memory 2x the performance per watt of AMD's Hawaii GPU.

As you can see, this GPU is not particularly long, measuring at the same length as a regular PCIe connection. This is due to AMD's use of HBM memory, allowing memory to take up 95% less space than the equivalent amount of GDDR5. This also allows AMD to have more freedon when it comes to the design of the power circuitry on this small form factor.

This GPU is smaller than AMD's new Flagship the Fury X GPU, making this GPU one of the most performance dense GPUs ever constructed.

As we can see from these pictured from the OCN forums, we can see that this GPU allows some very performance dense systems to be created, with the above pictures showing this GPU with an X99 ITX system in a space which is shorter than most ATX motherboards.

AMD's R9 Fury Nano GPU is one of AMD's most interesting releases of this generation, potentially being more power efficient than Nvidia's latest Maxwell GPUs. Hopefully AMD will be able to continue increasing their power efficiency as they move forward on to 14nm or 16nm FinFET based transistors with future generation GPUs.

You can join the discussion on AMD's R9 Fury Nano Specifications on the OC3D Forums.
