That said, on April 4th Radeon RX 580 and Radeon RX 570 will be available for sale. A week later, on April 11th AMD will unveil its Radeon RX 560 and Radeon RX 550 series. All cards, except RX 550, are most likely rebranded from Radeon RX 400 series.

So in other words, expect Radeon RX 500 rebrands in April and Vega a month or two later.

AMD Radeon RX 580 To Feature Polaris 20 and RX 560 To Feature Polaris 21 GPUs

While the Radeon RX 400 series used the 14nm LPE process, RX 500 series would utilize the 14nm LPP process node.

• 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.

However, this rumor does not end here. According to to the same site, AMD will allegedly use 14nm FinFET LPP (Low Power Plus) process, rather than 14nm FinFET LPE (Low Power Early) process as “it did” for Polaris (2016). The only problem is, there is no information that AMD was using LPE process for Polaris 1X in the first place. In fact, GlobalFoundaries do not even list such process on their website and plans LPP production for AMD products were announced back in 2015. That said, I would be very skeptical about this part because to my knowledge Polaris was already manufactured in LPP.
