AMD Radeon R9 300 series details leak

Take it with a pinch of salt, but WCCF Tech dug up some details about AMD's upcoming 20nm Radeon R9 300 series. Codenamed Pirate Islands, this series will feature the Bermuda XTX (R9 390X), Treasure Island XTX (R9 370X) and Fiji XTX (R9 380X) cores.

This new high-end lineup will reportedly be made on a 20nm TSMC process and is expected to feature the DirectX 12 hardware feature set. Exact details about the intended launch dates are unknown but it's expected to be in the second half of this year.
Now according to the details, we will see the R9 390X before the R9 380X. The R9 390X will feature the ‘Bermuda XTX’ core and feature a staggeringly high number of SPs, ie. 4224. The Texture Unit count is 264 with 96 ROPs. It is slated to show up late 2014 around November or so. Once again keep in mind the TSMC comment above. Finally the R9 380X which will feature the ‘Fiji XTX’ core and the following die configuration: 3072 SPs, 192 Texture Units and 72 ROPs and should appear sometime early 2015. Now interestingly the R9 390X ‘Bermuda XTX’ GPU is slated to have 512 Bits of Memory Bus while as the R9 380X is slated to have 384 Bits with the R9 370X coming last with 256 Bits. Now the road-map even hints at the clock speeds of AMD’s future GPUs but I think it is prudent to mention that all these tech specs at this point in time are about as solid as the wind. However let us continue, with the help of this table:
GPU Codename Core Stream Processors* Texture Units* ROPs* Core Clock* Memory Clock* Memory Bus*
 R9 370X Treasure Island Treasure Island XTX 1536 96 48 ~900Mhz ~5Ghz 256Bit
 R9 380X Fiji Fiji XTX 3072 192 72 ~900Mhz ~6Ghz 384Bit
R9 390X Bermuda Bermuda XTX 4224 264 96 ~1000Mhz ~7Ghz 512Bit

* Values are not indicative of the final product.
