AMD A4-9120 vs AMD A6-9210 vs AMD A9-9420e

AMD A4-9120

► remove from comparison AMD A4-9120

The AMD A4-9120 is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation), which was announced mid 2017. At its launch, the A4-9210 is a mid-range 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 2.2 - 2.5 GHz. It also includes a Radeon R3 GPU with 128 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.

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 range, the A4-9120 should be noticeably slower than the A6-9210 or A9-9410.

Graphics Card

The integrated Radeon R2 (Stoney Ridge) GPU offers only 2 CUs (=128 shaders) and a core clock of 655 MHz. More details about the GPU are available in the linked articles above. 

Power Consumption

AMD specifies the TDP of the A4-9120 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.

AMD A6-9210

► remove from comparison AMD A6-9210

The AMD A6-9210 is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation), which was announced mid 2016. At its launch, the A6-9210 is the mid-range 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 2.4-2.8 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.

Performance

Because of the significantly lower clock range, the A6-9210 should be noticeably slower than the A9-9410.

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 600 instead of 800 MHz. More details about the GPU are available in the linked articles above. 

Power Consumption

AMD specifies the TDP of the A6-9210 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.

AMD A9-9420e

► remove from comparison 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.

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.
