Intel Celeron N3350 vs AMD A6-9225 vs AMD A4-9120C
Intel Celeron N3350
► remove from comparisonThe Intel Celeron N3350 is an Apollo Lake family, dual-core, ultra-low-power processor (SoC) that saw the light of day in 2016. Its two cores run at 1.1 GHz to 2.4 GHz; these are not Hyper-Threading-enabled meaning there are no additional threads. This chip has a fairly competent integrated graphics solution, the Intel HD Graphics 500, and eats very little (~6 W).
Amusingly enough, Intel keeps making and selling the Celeron as of late 2022, albeit the price has dropped from about $100 to about $20 per unit making the CPU even more popular with ultra-budget nettop and laptop makers.
Architecture & Features
Just like other Celeron N, Celeron J, Pentium N, Pentium J processors, this Celeron is notable for its small die size. It is easy to manufacture, lowering the costs and enabling Intel to compete with various ARM-based products (hello, Raspberry Pi).
The Celeron N3350 features the Goldmont CPU microarchitecture. This replaces the dated Silvermont (2013), bringing with it several welcome improvements and making for a double-digit IPC improvement. There is still no L3 cache to be found here, however, it now takes less cycles to perform many operations.
The Celeron is compatible with DDR3L-1866, LPDDR3-1866, LPDDR4-2400 RAM. Intel's guidelines state that up to 8 GB are supported; that being said, various forum users report that the CPU functions just fine if mated to 16 GB and even 32 GB of RAM. The chip features six PCI-Express 2.0 lanes for connecting various devices, meaning a four-lane NVMe SSD will not be able to deliver a data transfer rate of more than 2 GB/s. eMMC and SATA storage is supported natively, too.
This Intel CPU is Secure Boot-compatible; technically, it will have no issue running 64-bit Windows 11. However, Microsoft only allows Windows 11 to be installed on systems with CPUs released in 2017 or later, making 64-bit Windows 10 the only OS that the Celeron is officially compatible with.
Last but not the least, please keep in mind that this is not a user-replaceable CPU. It gets permanently soldered to the motherboard (BGA1296 socket interface).
Performance
The average N3350 in our database is just as fast as the Atom x5-Z8300 and the Core 2 Duo SU7300, as far as multi-thread benchmark scores are concerned. Which is not fast at all. In fact, the two cores of this Celeron trail behind a single core of any half-decent CPU such as Intel's very own Core i3-7130U. A proper x86 CPU, Celeron N3350 will let you run nearly any Windows app, the caveat being that you will have to wait for several seconds every time you click on something. Windows 10 takes nearly a minute to fully boot with this CPU.
Graphics
The Intel HD Graphics 500 (Apollo Lake) is the highlight of this little Celeron. As far as the feature set is concerned, the HD Graphics 500 is not much different from the HD Graphics 520 or any other graphics adapter that full-blown six-generation Intel Core i3/i5/i7 chips have. This iGPU is compatible with DX12; it will drive up to 3 monitors with resolutions as high as 2160p60. It will happily decode VP9 and AVC-encoded videos, too. These are the two codecs that YouTube mostly relies on, as of 2021.
It's not all roses and sunshine. To keep power consumption under control, the number of Execution Units was reduced to 12 (the HD Graphics 520 has 24 EUs at its disposal, for reference). Besides, the UHD Graphics runs at up to 650 MHz which is not a lot. Very few games will be playable on this graphics solution - mostly, ones that were released in the 2000s or even in the 1990s.
Power consumption
The Celeron's default TDP (also known as the Power Limit 1) is 6 W, making it a great option for passively cooled systems. Increasing the PL1 by one or two watts, which many systems built around Apollo Lake allow one to do, makes for a much more responsive user experience, speaking subjectively.
Energy efficiency isn't great here, as Intel's 14 nm processes are very old as of mid 2022.
AMD A6-9225
► remove from comparisonThe 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 one year older A4-9220, the A4-9225 has a 200 MHz higher CPU Boost clock but a slower iGPU. It integrates two CPU cores (one Excavator module with 2 integer and one FP unit) clocked at 2.6 GHz to 3.1 GHz. It also includes a Radeon R4 GPU, probably with 192 shaders at up to 686 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 to 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 9225 in our database proves to be a very, very, very slow processor, its multi-thread benchmark scores only just matching those of the Core 2 Duo P8600 (a dual-core CPU that saw the light of day in 2008). This is a record-breakingly poor performance and a warning to anyone looking to purchase a system built around this specific A6 series CPU.
Graphics
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 686 MHz instead of 800 MHz. More details about the GPU are available in the linked articles above.
Power consumption
This AMD A6 series chip has a default TDP (also known as the long-term power limit) of 15 W. Laptop makers are allowed to reduce that value somewhat, 10 W being the lower limit, with clock speeds and performance changing accordingly 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 A6-9225 is built with a 28 nm process leading to very, very low energy efficiency, as of 2022.
AMD A4-9120C
► remove from comparisonThe 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.

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.

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).
