We've been hearing rumbles of the Radeon RX 500 series for a while, but now we're getting more specific news on what GPU the refresh will use. We're still looking at the Polaris GPU architecture, but they're using a new node process, known as 14LPE and 14LPP.

14LPE (Low Power Early) - Early time-to-market version with area and power benefits for mobility applications.
14LPP (Low Power Plus) - Enhanced version with higher performance and lower power; a full platform offering with MPW, IP enablement and wide application coverage.

AMD shifting its new Radeon RX 500 series to the 14LPE/14LPP nodes won't be the same as the larger shift from 28nm to 14nm FinFET, but it will be a nice little bump. Inside of the Radeon RX 580, we're now expecting the higher-clocked Polaris 20 XTX GPU, with 2304 stream processors, 144 TMUs, and 32 ROPs with 8GB of GDDR5 RAM at 8Gbps.
