AMD A4-9120C vs AMD A6-9220C

AMD A4-9120C

► remove from comparison AMD A4-9120C

The AMD A4-9120C is an entry-level chip from the Stoney-Ridge APU series for Chromebooks and entry level laptops (7th APU generation from 2016), which was announced early 2019. It is based on the similar named A4-9120 from 2016 but with a reduced TDP (6 versus 15 Watt) and reduced clock speeds of 1.6 - 2.4 GHz (compared to 2.2 - 2.5 GHz). Both CPUs integrate two CPU cores (one Excavator module with 2 integer and on FP unit).

It also includes a Radeon R4 GPU 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.

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 A4-9120C should be noticeably slower than the old A4-9120. AMD compares the A4-9120C with the Celeron N3350 in ChromeOS and sees a significant performance advantage for the A4. The efficiency however should be clearly worse as the A4-9120C is still manufactured in 28nm.

Power Consumption

AMD specifies the TDP of the A4-9120C with 6 Watts which should enable thin and light Chromebooks (even fanless).

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).

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.
