2026 verdict
Two Beelink boxes from different eras, and the newer Beelink EQR7 (7735U 16GB + 500GB) wins this mini PC comparison on processor and memory speed.
Its eight-core Ryzen 7 7735U with Radeon 680M graphics and LPDDR5-4800 is a clear step up from the dual-core Ryzen 3 3200U with DDR4-2400 in the smaller machine, and it adds dual 2.5G Ethernet, two M.2 PCIe 4.0 slots and a built-in 85W supply. The Beelink SER3 (16GB + 500GB) wins on price and owner rating, and it offers a genuinely quiet, low-power entry desktop with Windows 11 Pro, dual HDMI and a strong record of long service. Buy the Beelink SER3 (16GB + 500GB) for the cheapest light desktop duty, and the Beelink EQR7 (7735U 16GB + 500GB) for real processing power, faster networking and a home-lab role.

What the differences mean
Processor and memory
The Beelink EQR7 (7735U 16GB + 500GB) runs an eight-core Ryzen 7 7735U with LPDDR5-4800, which is far quicker than the dual-core Ryzen 3 3200U and DDR4-2400 in the Beelink SER3 (16GB + 500GB). Both ship 16GB, but only the SER3's memory is upgradeable, and only to 32GB.
Graphics
The Beelink EQR7 (7735U 16GB + 500GB) carries Radeon 680M graphics with twelve cores, enough for older and lighter games at reduced settings. The Beelink SER3 (16GB + 500GB) has Vega 3 graphics, which handle media playback and little else.
Networking
The Beelink EQR7 (7735U 16GB + 500GB) has two 2.5 Gigabit Ethernet ports, useful for a firewall, NAS or separated home-lab network. The Beelink SER3 (16GB + 500GB) has a single Gigabit port and Wi-Fi 6, which covers an ordinary desk but not fast local transfers.
Storage
Both ship about half a terabyte, the Beelink SER3 (16GB + 500GB) on a PCIe 3.0 drive and the Beelink EQR7 (7735U 16GB + 500GB) on PCIe 4.0. The EQR7 also runs two M.2 2280 slots, so a second drive can be added, while the SER3 has one.
Price, warranty and power
The Beelink SER3 (16GB + 500GB) is the cheaper and better rated machine. Both carry a three-year warranty, but only the Beelink EQR7 (7735U 16GB + 500GB) has a built-in 85W supply, while the SER3 uses an adapter the catalog does not document.
Which one to buy if
- the budget is the limit and the work is browsing, documents and media
The Beelink SER3 (16GB + 500GB) covers those tasks quietly and costs the least of the two.
- you need eight cores for multitasking or a home lab
The Ryzen 7 7735U in the Beelink EQR7 (7735U 16GB + 500GB) is several classes above the SER3's dual-core chip.
- you want faster wired networking or two network ports
Only the Beelink EQR7 (7735U 16GB + 500GB) has dual 2.5G Ethernet; the SER3 is Gigabit only.
- you plan to add memory later
The Beelink SER3 (16GB + 500GB) uses two DDR4 SO-DIMM slots, while the EQR7's LPDDR5 is soldered and fixed at 16GB.

What owners say
Owners of both Beelink machines open with the same note, that the box runs quieter than they expected. Beelink SER3 (16GB + 500GB) owners go further on longevity, reporting units still working after years of daily use, and they value the dual 4K HDMI output, the accessible DDR4 slots and the low price; their warnings are the dual-core processor, scattered reports of reboots and crashes, and memory that stops at 32GB. Beelink EQR7 (7735U 16GB + 500GB) owners describe a fast, responsive machine that replaces a tower for office work, with Radeon 680M graphics good for older games and dual 2.5G ports for a home lab; they warn instead that the 16GB of LPDDR5 is soldered and cannot be upgraded, and a few report unexpected restarts.
