AMD Radeon R4 Graphics (Stoney Ridge, 3 CU)

Radeon R4 Graphics with three compute units is the integrated GPU of AMD's Stoney Ridge A6 APUs, introduced in 2016 as part of the 7th Generation A-Series mobile family. It is used in the A6-9200, A6-9200e, A6-9210 and A6-9225 and in the Chromebook-oriented A4-9120C, with GPU clocks of 600 MHz to 686 MHz depending on the model; AMD lists the A6-9220 with the same three-CU GPU under the Radeon R5 Graphics name. Based on third-generation GCN on a 28 nm process, it shares single-channel DDR4 system memory with the CPU and adds hardware VP9 decoding.
