Overview of the HP Pro 400 Business Mini Computer
The HP Pro 400 Business Mini Computer comes with a significantly higher price tag of $1,499.99, but it is tailored for business environments. It is powered by an Intel Celeron G6900T processor and offers up to 64GB of DDR5 RAM, providing ample power for everyday tasks and business applications.

Performance Comparison
The GMKtec M6 Ultra Gaming Mini PC features an AMD Ryzen 5 7640HS processor that operates with a base speed of 4.3 GHz and can turbo boost up to 5.0 GHz. This performance is suitable for moderate gaming and multitasking. In contrast, the HP Pro 400 uses an Intel Celeron G6900T processor with a 2.8 GHz clock speed. While the Celeron is adequate for basic tasks, it does not provide the same level of performance for gaming or demanding applications as the Ryzen 5.
Memory and Storage
The GMKtec M6 comes with 32GB of DDR5 RAM, which is expandable up to 128GB, and features a 512GB SSD that can be expanded to 8TB. This configuration is particularly appealing to gamers and power users who require speed and multitasking capabilities. The HP Pro 400, on the other hand, offers a maximum of 64GB DDR5 RAM and a generous 2TB PCIe SSD, which is adequate for most business applications but may not meet the needs of users who require extensive storage and high performance.
Connectivity Features

Its compact design allows it to fit easily into various environments, whether for gaming or office use. The HP Pro 400 also boasts a compact and sleek design, weighing under 3 pounds and engineered for durability. While both mini PCs are designed for space-saving, the GMKtec's triple display capability enhances its usability for multitasking.
Target Audience
The GMKtec M6 Ultra is aimed at gamers and tech enthusiasts who want a powerful mini PC that can handle both gaming and productivity tasks without breaking the bank. Its price point at $499.99 makes it accessible for budget-conscious gamers looking for performance. In contrast, the HP Pro 400 is designed for business professionals requiring a reliable machine for daily computing and multitasking. Its higher price of $1,499.99 reflects its focus on enterprise-grade performance and reliability.
Which should you buy?
If you are looking for a budget-friendly gaming mini PC that offers solid performance and multitasking capabilities, the GMKtec M6 Ultra Gaming Mini PC at $499.99 is an excellent choice. However, if your needs revolve around business and you require a machine with larger memory and storage options, the HP Pro 400 Business Mini Computer, despite its higher price of $1,499.99, may be worth the investment for its enterprise features and reliability. Ultimately, your choice should be guided by your specific use case and budget constraints.
