2026 verdict
A budget browsing box against the most maxed-out mini PC Geekom sells: the Geekom A9 Mega (128GB + 2TB) is the one to shortlist here, winning on owner rating, memory type, memory speed, memory capacity and storage capacity.
Its Ryzen AI Max+ 395 pairs a 128GB unified memory pool, shared with the graphics, and 2TB across two Gen4 NVMe slots with RAID support, next to the Beelink SER3 (16GB + 500GB)'s dual-core Ryzen 3 3200U and 16GB of DDR4. The Beelink SER3 remains the far cheaper of the two, and it is still a fine choice for browsing, office documents and 4K playback rather than local AI or GPU work. Pick the Geekom A9 Mega (128GB + 2TB) for local AI models or GPU-heavy creative work; keep the Beelink SER3 (16GB + 500GB) for a light everyday desktop on a tight budget.

What the differences mean
Processor and graphics class
The SER3 runs a dual-core Ryzen 3 3200U with Radeon Vega 3 graphics. The A9 Mega runs a sixteen-core Ryzen AI Max+ 395 with Radeon 8060S graphics and an XDNA 2 NPU, a completely different tier of machine built for local AI and GPU-adjacent work.
Memory pool
The SER3 ships 16GB of DDR4 expandable to 32GB. The A9 Mega ships 128GB of soldered LPDDR5X shared with its graphics, which is also its permanent ceiling since the memory cannot be added to later.
Storage
500GB on a single bay on the SER3 against 2TB across two Gen4 NVMe slots with RAID 0 or RAID 1 support on the A9 Mega.
Networking
The A9 Mega carries dual 2.5G Ethernet and Wi-Fi 7. The SER3 has a single Gigabit port and Wi-Fi 6.
Extras
The A9 Mega adds a fingerprint sensor and an SDXC card reader for sign-in and camera media. The SER3 has neither.
Which one to buy if
- the workload is browsing, documents and media on a strict budget
The Beelink SER3 (16GB + 500GB) is the far more affordable of the two and still covers that job well.
- you need a large unified memory pool for local AI models or GPU-heavy work
Its 128GB of LPDDR5X is shared directly with the Radeon 8060S graphics, something the SER3's platform cannot offer at any price.
- you want the most storage and the fastest memory standard available today
2TB across two Gen4 NVMe slots and LPDDR5X memory both outclass the SER3 by a wide margin.
- a fingerprint sign-in or a card reader matters
The Geekom A9 Mega (128GB + 2TB) has both; the SER3 has neither.

What owners say
Beelink SER3 (16GB + 500GB) owners tend to mention longevity before anything else, several reporting the machine still working well after a year and one after nearly five years of light daily use, which is not a common thing to read about a budget box. The near-silent fan, the properly licensed Windows 11 Pro and the fact that the 16GB of memory sits in two accessible slots all get repeat praise. Set against that, a minority describe spontaneous reboots or crashes within the first couple of months, and more than one owner says the dual-core processor runs out of headroom the moment several demanding programs run together.
Price history compared
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
