AMD A9-9425 vs Intel Celeron J4105
AMD A9-9425
► remove from comparisonThe 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 the Intel Core i3-4012Y. Much like it is with N-class Intel chips, 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
This A9 series chip has a default TDP of 15 W. Laptop makers are free to reduce that somewhat with 10 W being the minimum AMD-recommended value; clock speeds and performance will be reduced as a result. By going for the lowest value, it will be possible to build a passively cooled system around the APU.
Last but not the least, the AMD A9-9425 is manufactured on a 28 nm process for very, very low energy efficiency, as of 2022.
Intel Celeron J4105
► remove from comparisonThe Intel Celeron J4105 is a quad-core desktop SoC primarily for mini PCs and mini ITX mainboards. It runs at 1.5 - 2.5 GHz (Single Core Burst) and is based on the Gemini Lake platform. Similar to the Apollo Lake predecessor, the chip is manufactured in a 14 nm process with FinFETs but offers slightly improved processor cores, double the amount of L2 cache, a smaller package, a new generation of monitor outputs (Gen 10) and a partly integrated WiFi chip. Besides four CPU cores, the chip also includes a DirectX 12 capable GPU as well as a DDR4/LPDDR4 memory controller (dual-channel, up to 2400 MHz). The SoC is not replaceable as it is directly soldered to the mainboard.
Architecture
The processor architecture was slightly reworked and is now called Goldmont Plus. It features an increased level 2 cache (to 4 MB). That means the per-clock-performance should be a bit better, but not near the Core CPUs like Kaby Lake Y.
Performance
While we have not tested a single system built around the J4105 as of August 2023, we have tested a certain number of laptops featuring the Celeron N4120, a chip with very similar specs (4 cores, 4 threads, up to 2.6 GHz). Based on that, expect the J4105 to be very slow in all but the most basic activities.
