GMKtech has expanded its compact PC lineup with the launch of the NucBox M6 Ultra, a budget-friendly mini PC powered by AMD’s Ryzen 5 7640HS. 
Targeted at professionals, casual creators, and home users, the device balances affordability with capable performance.
At its core, the NucBox M6 Ultra houses AMD’s 6-core/12-thread Zen 4 Ryzen 5 7640HS processor, clocking up to 5.0 GHz. It’s paired with integrated Radeon 760M graphics based on RDNA 3, offering enough horsepower for light editing, office work, eSports, and older game titles – though it’s not designed for cutting-edge AAA gaming.
Connectivity is another highlight. The mini PC comes equipped with dual 2.5G LAN ports, WiFi 6E, and Bluetooth 5.2, ensuring fast internet and peripheral pairing
. For displays, users can leverage HDMI and DisplayPort outputs, while multiple USB-A ports and a USB4 Type-C connector cover modern accessory needs.
In terms of memory and storage, GMKtech provides flexible options. Buyers can start with a barebone unit (no RAM, SSD, or Windows OS) priced at $259. Pre-configured builds include a 16GB DDR5 + 512GB SSD setup for $339 and a higher-tier 32GB DDR5 + 1TB SSD model at $389. Users can expand memory up to 128GB and storage up to 8TB, making the system highly adaptable.
This model succeeds the earlier NucBox M6, which was built on Ryzen 5 6600H, offering a clear performance bump and better future-proofing. As part of the launch campaign, GMKtech is offering a $12 discount with promo code PRM6U12, valid between August 20 and August 31, 2025.
Overall, the NucBox M6 Ultra blends affordability, portability, and solid performance, making it a strong choice for users looking for a versatile mini PC without breaking the bank.
