Design and Build Quality

The GMKtec Mini PC Gaming features a compact and modern design ideal for gaming setups, while the HP Pro 400 Business Mini Computer emphasizes a sleek and durable form suited for professional environments. The GMKtec's small form factor makes it an attractive choice for gamers who value space efficiency, as it seamlessly fits into any gaming station. In contrast, the HP Pro 400 weighs under 3 pounds and measures just 17.7 x 17.5 x 3.4 cm, combining portability with HP's reputation for reliability. Both products exhibit a premium build, but the GMKtec leans towards a gaming aesthetic, whereas the HP focuses on a professional look.

Performance and Processing Power

The GMKtec Mini PC Gaming is powered by an AMD Ryzen 7 7840HS processor, capable of boosting up to 5.1 GHz, which provides robust performance for multitasking and gaming. In comparison, the HP Pro 400 incorporates an Intel Celeron G6900T processor, which operates at 2.8 GHz. This significant difference in processing power suggests that the GMKtec is better suited for heavy gaming and multitasking, while the HP Pro 400 is designed for everyday business tasks. The GMKtec's AMD Ryzen 7 processor provides superior capabilities compared to the Intel Celeron, making it a more powerful option for demanding applications.

Memory and Storage

When it comes to memory and storage, the GMKtec Mini PC offers 32GB DDR5 RAM, expandable to 64GB, and a 1TB PCIe 4.0 SSD, with support for dual slots up to 4TB. The HP Pro 400 takes this further, featuring 64GB RAM and a 2TB PCIe SSD, making it ideal for users who require extensive memory for multitasking and larger storage for files. While the GMKtec is well-equipped for gaming with expandable options, the HP Pro 400's higher standard configurations provide a clear advantage for business users needing significant resources for data-intensive applications.

Graphics Capabilities

The integrated graphics of the GMKtec Mini PC Gaming are powered by the AMD Radeon 780M, which is noted to perform closely to a full NVIDIA GTX 1650 Ti. This makes the GMKtec an excellent choice for gamers who want decent graphics performance without a dedicated GPU. In contrast, the HP Pro 400 relies on Intel UHD Graphics, which is more than sufficient for everyday tasks but falls short for gaming or graphic-intensive applications. For users prioritizing gaming and graphic-heavy tasks, the GMKtec is the clear winner in this category.

Connectivity Options

Both mini PCs offer a range of connectivity options, but the GMKtec Mini PC Gaming stands out with dual 2.5Gbps LAN ports, WiFi 6E, and Bluetooth 5.2, providing superior internet connectivity and faster data transfer. The HP Pro 400 also offers WiFi 6 and a variety of ports including USB Type-C and DisplayPort, but lacks the dual LAN capabilities of the GMKtec. While both devices ensure modern connectivity, the GMKtec's advanced options give it a notable advantage for users requiring high-speed internet and versatile connectivity.

Usability and Software

The GMKtec Mini PC Gaming does not come with a pre-installed operating system listed, whereas the HP Pro 400 is equipped with Windows 11 Pro, which is optimized for productivity and multitasking. This makes the HP ready to use for business environments right out of the box. The GMKtec, while powerful for gaming, may require additional setup for software and operating systems, making it potentially less user-friendly for those not inclined to handle installations. Thus, for users seeking a plug-and-play experience, the HP Pro 400 is a better option.

Pricing and Value

The GMKtec Mini PC Gaming is priced at $639.99, while the HP Pro 400 is significantly more expensive at $1,499.99. This makes the HP Pro 400 about 134% pricier than the GMKtec. For users on a budget or those prioritizing gaming performance, the GMKtec offers excellent value without compromising on essential features. However, the HP Pro 400 justifies its higher price with superior memory, storage, and an integrated operating system, making it a fitting choice for business-centric users with demanding requirements.

Which should you buy?

Choosing between the GMKtec Mini PC Gaming and the HP Pro 400 Business Mini Computer largely depends on your intended use. If gaming and performance are your priorities, the GMKtec offers superior processing power, graphics capabilities, and a more affordable price point. Conversely, if you need a reliable machine for business tasks with ample memory and storage right from the start, the HP Pro 400 is a compelling choice, albeit at a higher cost. Each product caters to different needs, making the decision ultimately reliant on whether you prioritize gaming performance or business functionality.
