MagyarAMD A9-9425 vs AMD E2-9000
AMD A9-9425
► remove from comparison
The AMD A9-9425 is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation), which was announced mid 2018. Compared to the one year older A9-9420, the 9425 has a 100 MHz higher CPU clock speed (base and boost) as well as a marginally faster iGPU. It integrates two CPU cores (one Excavator module with 2 integer and on FP unit) clocked at 3.1 GHz to 3.7 GHz. It also includes a Radeon R5 GPU with 192 shaders at up to 900 MHz as well as a single-channel DDR4-2133 memory controller, H.265 video decoder 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
The average 9425 in our database proves to be a rather slow CPU, its multi-thread benchmark scores only just matching those of Intel Core i3-4012Y. Much like with Intel Celerons, expect a system built around an A9-9425 to perform poorly in all but the most basic tasks.
Graphics
The integrated Radeon R5 (Stoney Ridge) GPU has 192 active shader units (3 compute cores) clocked at up to 900 MHz. More details about the GPU are available in the linked articles above.
Power Consumption
AMD specifies the TDP of the A9-9425 with 15 Watts, but it can be configured between 10-15 Watts. This means the CPU is a good choice for thin and light notebooks, but also 15-inch devices with better cooling capabilities.
AMD E2-9000
► remove from comparison
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).

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.
