Overview of GMKtec M3 Ultra Mini PC and HP Pro 400 Business Mini Computer
The GMKtec M3 Ultra Mini PC is priced at $599.99, making it approximately 60% cheaper than the HP Pro 400 Business Mini Computer, which costs $1,499.99. This substantial price difference is reflective of the distinct target audiences and performance capabilities of each device. The GMKtec M3 is designed for users who prioritize power and compactness, while the HP Pro 400 caters more towards business environments requiring extensive multitasking capabilities.
Performance Comparison
The GMKtec M3 Ultra Mini PC is powered by an Intel Core i7 12700H processor, boasting 14 cores and a turbo frequency of 4.7 GHz, which provides exceptional performance for gaming and creative tasks. In contrast, the HP Pro 400 features an Intel Celeron G6900T processor, which, while efficient for everyday tasks, lacks the raw processing power found in the GMKtec. The stark difference in processing capabilities makes the GMKtec M3 a superior choice for demanding applications.
Memory and Storage Capacity
When it comes to memory and storage, the GMKtec M3 offers 16GB of DDR4 RAM and a 512GB NVMe SSD, expandable to 4TB. The HP Pro 400, however, supports a remarkable 64GB of DDR5 RAM and a 2TB PCIe SSD. While the GMKtec has a lower base memory, the HP Pro 400 provides a significant advantage in multitasking and storage capacity, making it ideal for users who handle large datasets or run multiple applications simultaneously.
Graphics Performance
The GMKtec M3 Ultra Mini PC features integrated Intel Iris Xe Graphics, capable of supporting triple 4K displays. This is particularly beneficial for professionals engaged in content creation or data analysis. The HP Pro 400, equipped with Intel UHD Graphics, can also support dual 4K displays but lacks the advanced capabilities of the Iris Xe Graphics. Thus, for users needing superior graphics performance, the GMKtec is the clear winner.
Design and Build Quality
In terms of design, the HP Pro 400 emphasizes a compact and durable structure ideal for business settings. Weighing under 3 pounds, its ultra-quiet operation makes it a suitable choice for office environments. The GMKtec M3, while also compact, focuses more on delivering high-end performance in a small form factor. Users looking for a reliable machine that blends seamlessly into a professional setting may prefer the HP Pro 400.
Connectivity Options
The GMKtec M3 Ultra Mini PC features a variety of connectivity options, including dual HDMI and a USB-C port, enabling multiple display outputs and fast data transfer.

On the other hand, the HP Pro 400 boasts an extensive array of ports, including multiple USB Type-A and Type-C connections, as well as HDMI and DisplayPort options. This makes the HP Pro 400 more versatile for users needing to connect various peripherals and devices.
Operating System and Software
The GMKtec M3 Ultra Mini PC does not specify its operating system, while the HP Pro 400 comes pre-installed with Windows 11 Pro, which is optimized for business use and includes features for multitasking and collaboration. This makes the HP Pro 400 more suitable for users who require an out-of-the-box solution for professional environments.
Which should you buy?
Choosing between the GMKtec M3 Ultra Mini PC and the HP Pro 400 Business Mini Computer largely depends on your specific needs. If you need a powerful, budget-friendly machine for gaming or intensive tasks, the GMKtec M3 at $599.99 offers outstanding performance. However, for business users requiring extensive multitasking capabilities, ample memory, and professional-grade software, the HP Pro 400, despite its higher price of $1,499.99, provides superior value in a professional setting.
