Running Score Comparison

Performancee Beyond Core i7-1165G7 in both Cinebench R20 and 3DMark 11 Professional Edition.


Recommended reason

First Waterproof Fabric Design in Mini PC

The top case of SEi12 1235U is made of waterproof fleece, so you don't worry about accidentally getting water on the machine, and the texture of the fabric makes the mini-computer feel like an old friend.

Patented Dual fan Design for Cooling!

SEi12 1235U adopts a 3-sided air inlet design to enlarge the air inlet; 2 built-in cooling fans, one for system cooling (DDR4 + SSD + motherboard) and one for CPU cooling. PCIe4.0 runs faster and more stable.
