Specifications for AMD’s RX 500 series leak online

 
Specifications for AMD’s RX 500 series leak online, with some suggesting that the new series of GPUs will use a more advanced version of GlobalFoundries’ 14nm manufacturing process. 
 
It has been suggested by Benchlife that AMD will be moving from GlobalFoundries’ 14nm LPE (Low Power Early) to 14nm LPP (Low Power Plus), though at this time we cannot find any evidence that AMD’s original Polaris GPUs didn’t run on 14nm LPP.  If this is true AMD can gain some significant performance advantages and power reductions by using this new process, with this process offering 15%  
 
If this is true AMD can gain some significant performance advantages and power reductions by using this new process, with this process offering 15% higher switching speeds and 15% lower power draw. These changes can help AMD offer some significant performance gains with their RX 500 series, despite the fact that they are based on the same Polaris architecture as their RX 400 series.   
 
Below are some likely specifications for AMD’s RX 500 series of GPUs, with AMD adding an entry-level RX 550 GPU to the lineup and replacing their RX 460 with a fully enabled Polaris 10 GPU, offering 128 more GPU cores/stream processors. 
 
It has been suggested that AMD will be renaming their new Polaris 10 and 11 versions Polaris 20 and 21, to signify this change from 14nm LPE to 14nm LPP.

RX 470 Polaris 10 2048 1206MHz 4/8GB 6.6GHz 256-bit
RX 570 Polaris 20 2048 1266MHz? 4/8GB  7GHz? 256-bit
RX 480 Polaris 10 2304 1266MHz 4/8GB 8GHz 256-bit
RX 580 Polaris 20 2304 1340MHz? 4/8GB    256-bit

 

Right now it is unknown how high clock speeds will be on AMD’s RX 500 series, though it is likely that they will offer increased boost clock speeds and use higher speed memory for improved memory performance on select SKUs. At this time the clock speeds of AMD’s RX 500 series remain unconfirmed. 

Recent rumours suggest that AMD’s RX 500 series will release in mid-April, though at this time AMD has not made any official announcements.
