AMD RX 500s Powered by 14nm FinFET LPP Polaris 21, 20, and 12

While AMD’s RX 500 Series graphics cards are expected for release next month, we still know very little about them. A new report from Benchlife, though, suggests that the new Radeon hardware will boast a revised process based on the next-gen Polaris architecture, built on 14nm FinFET LPP. The 14nm FinFET LPP process retains the same Polaris architecture of the RX 400 Series, which used a 14nm LPE process, but with improved efficiency.

If the report is to be believed, the new Radeon RX 580 will boast a Polaris 20 XTX GPU, which features a full 2304 cores, 144 TMUs, 6.17 TFLOPS, and 32 ROPs, and is clocked at 1340MHz boost, plus 8GB of GDDR5 RAM clocked at 8.0 GHz, and a 256-bit bus interface. The RX 570 will feature a Polaris 20 XL GPU with a cut-down 2048 cores, a clock of 1244MHz boost, and 5.10 TFLOPS of compute power. Meanwhile, Polaris 11 – rebranded as Polaris 21 using the new process – will be powering the RX 560, which is expected to have a similar clock of 1287MHz as the RX 460, plus 2.63 TFLOPS, 4GB of GDDR5 memory, and a 128-bit bus interface.

AMD’s Radeon RX 500 Series are expected for release in mid-April, prior to the eagerly-awaited launch of the Radeon RX Vega series graphics cards – the company’s successor to its high-end Fury series – during the late-second-quarter of 2017.
