AMD A9-9420e

AMD A9-9420e

The AMD A9-9420e is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation). It was first found in the Dell Inspiron 3000 with passive cooling and 4 GB DDR4 RAM. The performance in that device was way below the normal A9-9420 as the clock speed only reached up to 2,5 GHz. It also includes a Radeon R5 GPU with 192 shaders as well as a single-channel DDR4-2133 memory controller, H.265 video engine and chipset with all I/O ports.

Architecture

Stoney Ridge is the successor of the Carrizo architecture and the design is almost identical. Thanks to optimized manufacturing processes and more aggressive Boost behavior, however, the clocks are a bit higher at the same power consumption. The memory controller now also supports DDR4-RAM, in this case up to 2133 MHz. Stoney Ridge is the designation for the smaller dual-core and single-core chip, while Bristol Ridge is the bigger quad-core chip with dual-channel memory controller. More technical details are available in the following articles:

Power Consumption

AMD specifies the TDP of the A9-9420 between 10-25 Watts, but the passively cooled A9-9420e should be positioned lower than 9 Watt.
