AMD Radeon 660M

384 cores

The Radeon 660M is AMD's entry RDNA 2 integrated GPU for Ryzen 5 laptop processors of the Ryzen 6000 (Rembrandt) and Ryzen 7035 (Rembrandt-R) series, including the Ryzen 5 6600U/6600H/6600HS, Ryzen 5 PRO 6650U/6650H/6650HS and Ryzen 5 7535U/7535H/7535HS, and of their Ryzen 100 Series renames, the Ryzen 5 130 and Ryzen 5 150. In these chips it has six compute units running at up to 1900 MHz, with hardware ray tracing and AV1 decode. The budget Ryzen 3 7335U and Ryzen 3 110 use a cut-down 660M with four compute units at up to 1800 MHz.
