AMD Pirate Islands : R9 300 Series Alleged Specifications Detailed, Flagship Cores Bermuda XTX, Treasure Island XTX and Fiji XTX
*Nothing mentioned in this leak is set in concrete, the tech specs mentioned are as solid as the wind .
[Exclusive] [Editorial]: I have just recently gotten my hands on a somewhat outdated and alleged AMD GPU specification details, the essentials of which should nonetheless hold true. The specifics mentioned in this post are liable to change and the primary focus of this leak is to serve as the basis of all future Pirate Islands speculation. This is going to be a very very interesting post, so buckle up, but keep that pinch of salt handy.
AMD Pirate Islands GPUs: R9 390X 'Bermuda' R9 380X ' Fiji' R9 370X ' Treasure Island'
So lets begin, basically the AMD Details show three GPUs, the R9 390X, R9 380X and R9 370X, namely the Pirate Islands series. According to these details all GPUs will be based on the TSMC 20nm Node and will be true Pirate Island cores, which is why nomenclature of the dies will be derivative in nature. Another thing mentioned is that all Pirate Island GPUs will have the DirectX 12 Hardware Feature Set. According to these details the R9 370X is slated for announcement/arrival sometime this July-August this year. The R9 370X will feature a 'Treasure Island XTX' core and supposedly has 1536 Stream-processors, 96 Texture Units and 48 ROPs on the uncut die. Of course this road-map precedes the report we got of TSMC having a little trouble with 20nm so I am not sure how valid the time frame is anymore.
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.
So summarizing, we have the first basic idea about the upcoming 20nm Pirate Islands GPUs from AMD. We know all of them should feature the DirectX 12 Hardware feature set and unless this road-map is completely off (very unlikely) then we will see Pirate Islands well before the year is over. Of course anyone could have figured out this road-map with a bit of common sense (Maxwell 20nm is due in about the same time frame of second half of 2014) but it helps to have solid and to the point information. So this is it folks, the first reference point to all future speculation and leaks on Pirate Islands from AMD.
