Radeon RX 540 offers a tiny slice of Polaris power to notebooks
by from Techreport on (#2KKMA)
AMD's high-octane Radeon RX 500-series graphics cards are powered by respins of existing Polaris silicon, but the entry-level Radeon RX 550 features a tiny (and as-yet-unnamed) new GPU that AMD said was meant to make its way into notebooks, as well. Now, a product page for the mobile version of that mini-GPU has appeared on AMD's website. It seems we can expect this power-sipping Polaris chip to appear in notebooks as the Radeon RX 540.
