AMD E2-9010 vs AMD A6-9220e vs AMD A6-9220C

AMD E2-9010

The AMD E2-9010 is the least powerful chip from the Stoney-Ridge APU series for notebooks (7th APU generation) at the time of announcement in mid 2016. The SoC integrates two CPU cores (one Excavator module with 2 integer and on FP unit) clocked between 2.0-2.2 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.

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. More technical details are available in the following articles:

• AMD's Bristol Ridge and Stoney Ridge Architecture
• AMD: Bristol Ridge APUs announced

Power Consumption

AMD specifies the TDP of the E2-9010 with 15 Watts, but it can be configured between 10-15 Watts. This means the APU is intended for thin and light notebooks.

AMD A6-9220e

The AMD A6-9220e is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation), which was announced mid 2017. The 9220e is an entry-level Stoney Ridge processor (dual-core version of Bristol Ridge) and integrates two CPU cores (one Excavator module with 2 integer and on FP unit) clocked between 1.6 - 2.4 GHz. It also includes a Radeon R4 GPU, probably with 192 shaders at 600 MHz, as well as a single-channel DDR4-2133 memory controller, H.265 video engine and chipset with all I/O ports. Compared to the similar named A6-9220 the 9220e is significantly slower clocked (2.5 - 2.9 GHz) including the GPU (600 versus 655 MHz) and can be passively cooled thanks to the TDP of 6W.

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:

Performance

Because of the significantly lower clock speed, the A6-9220e is noticeably slower than the A6-9220. In the Cinebench R15 Multi benchmark the 9220 reaches 38% higher scores, in the single thread test its more than twice as fast (219% versus the 9220 in the HP 255 G6). Compared to Intel CPUs, the A6-9220e is on par with the old Celeron N2820 in Cinebench (single and multi core). Therefore, the CPU is placed in the lowest segment (performance wise) and only suited for light tasks and light multitasking.

Graphics Card

The integrated Radeon R4 (Stoney Ridge) GPU is probably similar to the R5 with 192 active shader units (3 compute cores), but a reduced clock of just 655 instead of 800 MHz. More details about the GPU are available in the linked articles above. 

Power Consumption

AMD specifies the TDP of the A6-9220e with 6 Watts and therefore significantly below the 15 W of the A6-9220. This means the APU can be passively cooled and is a good choice for thin and light notebooks.

AMD A6-9220C

The AMD A6-9220C is an entry-level chip from the Stoney-Ridge APU series for Chromebooks (7th APU generation from 2016), which was announced early 2019. Compared to the A6-9220, the 9220C is rated at a reduced TDP of 6 versus 15 Watt and also reduced clock speeds. It integrates two CPU cores (one Excavator module with 2 integer and on FP unit) clocked between 1.8 - 2.7 GHz (versus 2.5 - 2.9 GHz on the A6-9220).

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:

• AMD's Bristol Ridge and Stoney Ridge Architecture
• AMD: Bristol Ridge APUs announced

Performance

Because of the significantly lower clock speed, the A6-9220C should be noticeably slower than the old A6-9220. AMD compares the performance against the Pentium N4200 in ChromeOS and sees the A6-9220C clearly ahead. The efficiency should be worse however, due to the old manufacturing process.

Graphics Card

The integrated Radeon R4 (Stoney Ridge) GPU is a bit controversal, as AMD states 3 compute cores which should translate to 192 shaders.

Power Consumption

AMD specifies the TDP of the A6-9220C with 6 Watts which should enable thin and light (even fanless) Chromebooks.
