Rumor has it the Radeon R9 380X will feature 4,096 GCN coresKeeping in mind that nothing is ever official until it's official (one of the many mottos of Captain Obvious), purported details of AMD's forthcoming Radeon R9 380X have started to emerge. If they turn out to be accurate, you can expect the Radeon R9 380X to arrive sometime between April and June of this year with 4,096 GCN cores in tow, along with 4GB of 3D stacked High Bandwidth Memory (HDM).
That's according to WCCFTech, which is getting its information from Swedish website SWEClockers, "which have been proven to be quite accurate in their estimations." In this case, the report points to AMD running with the 380X nomenclature rather than 390X, which would indicate that an even more powerful graphics card is on tap for 2015.
As for the 380X, the use of HBM is reported to be 9 times faster than GDDR5. Looking at just the increased number of compute units, however, it's estimated that the 380X could be 45 percent faster than AMD's R9 290X, and that's without taking into considerations architectural improvements or memory bandwidth.
The card will be based on a GPU code named Fiji XT. Along with its release, AMD is expected to refresh its current lineup with new GPUs, including a Radeon R9 270 replacement called Trinidad.
