AMD E2-9000

The AMD E2-9000 is the least powerful chip from the Stoney-Ridge APU series for notebooks (7th APU generation) at the time of announcement in 2017. The SoC integrates two CPU cores (one Excavator module with 2 integer and on FP unit) clocked between 1.8-2.2 GHz. It also includes a Radeon R2 GPU clocked at 600 MHz as well as a single-channel DDR4-1866 memory controller, H.265 video engine and chipset with all I/O ports. Compared to the older E2-9010, the E2-9000 offers a lower base speed (1.8 versus 2 GHz).

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 1866 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.

Power Consumption

AMD specifies the TDP of the E2-9000 with 10 Watts (compared to the 9010 at 15W). This means the APU is intended for thin and light notebooks.
