AMD A6-9220C vs AMD A6-9225

AMD A6-9220C

► remove 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:

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.

AMD A6-9225

► remove AMD A6-9225

The AMD A6-9225 is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation), which was announced mid 2018. Compared to the 2 years older A4-9220, the A4-9225 offers a 100 MHz higher CPU clock. It integrates two CPU cores (one Excavator module with 2 integer and on FP unit) clocked between 2.6 - 3 GHz. It also includes a Radeon R4 GPU, probably with 192 shaders at 655 MHz, as well as a single-channel DDR4-2133 memory controller, H.265 video engine and chipset with all I/O ports.

More technical details are available in the following articles:

Performance

Because of the significantly lower clock range, the A6-9225 should be noticeably slower than the A9-9410. Therefore, it is in the absolute low end of 2018 mobile CPUs and only suited for basic tasks.

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 A6-9225 with 15 Watts, but it can be configured between 10-15 Watts. This means the APU is a good choice for thin and light notebooks.
