A new entry for what claims to be the Radeon RX 5500 has appeared on GFXBench. The new listing seemingly confirms that AMD will bring two RX 5xxx series to market, with the RX 5300 series confirmed to be making an appearance too. The RX 5500 series, expected to be based on AMD's Navi 12 GPU, will likely challenge the NVIDIA GeForce GTX 16 series for midrange market dominance.
