Performance Comparison

In terms of performance, the GMKtec M3 Ultra Mini PC significantly outshines the GMKtec Mini PC G3 S. The M3 Ultra is powered by an Intel Core i7 12700H processor, boasting 14 cores and a maximum turbo frequency of 4.7 GHz. This powerhouse is designed for intensive tasks, making it ideal for gaming and content creation. In contrast, the G3 S features a 12th Gen Intel N95 processor with 4 cores that can reach up to 3.4 GHz. While the G3 S is capable for routine office tasks and home entertainment, it falls short for users requiring high-end performance.

Graphics Capabilities

When it comes to graphics, the GMKtec M3 Ultra Mini PC is equipped with Intel Iris Xe Graphics, which provides a much smoother and more responsive experience for visual tasks. It supports triple 4K display outputs, allowing users to connect multiple monitors for enhanced productivity. On the other hand, the GMKtec Mini PC G3 S features upgraded Intel UHD Graphics, capable of dual 4K display support but lacks the same level of graphical performance. For users who need advanced graphics capabilities, the M3 Ultra is the clear winner.

Memory and Storage

In terms of memory and storage, the GMKtec M3 Ultra offers 16GB of DDR4 RAM and a 512GB NVMe SSD, which can be expanded to a total of 8TB. This is particularly beneficial for data-heavy applications. The GMKtec Mini PC G3 S also comes with 16GB of DDR4 RAM and a 512GB SSD, but it does not provide the same level of expandability as the M3 Ultra. For users who might need additional storage or plan to run memory-intensive applications, the M3 Ultra provides a more flexible option.

Connectivity Options

The GMKtec M3 Ultra excels in connectivity with a variety of ports including dual HDMI, a Type-C port, and supports WiFi 6 and Bluetooth 5.2. This allows for high-speed data transfer and seamless connectivity to multiple peripherals. In comparison, the GMKtec Mini PC G3 S offers dual HDMI outputs and supports WiFi 5 along with Bluetooth 5.0. While the G3 S still provides sufficient connectivity for most users, the added features of the M3 Ultra make it a more versatile choice for those needing advanced connectivity options.

Design and Form Factor

Both mini PCs are designed to be compact, but the GMKtec M3 Ultra is engineered for higher performance in a small form factor. The M3 Ultra's sleek design supports a triple 4K display setup, enhancing its appeal for professionals who need a powerful workstation in a confined space. The G3 S, while also a mini desktop, is better suited for basic office work and home entertainment. The M3 Ultra's design reflects its advanced capabilities, making it a more fitting choice for users seeking high-performance computing.

Price Comparison

The GMKtec Mini PC G3 S is significantly more affordable at $259.99, about 57% cheaper than the GMKtec M3 Ultra Mini PC, priced at $599.99. This price difference makes the G3 S a compelling option for budget-conscious consumers who do not require high-performance specifications. However, for those who need the extra power and capabilities provided by the M3 Ultra, the investment may be justified. The price difference reflects the specifications and intended use of each device, making it essential for consumers to consider their needs.

Sales Performance

The GMKtec M3 Ultra Mini PC currently holds a sales rank of 757, indicating a competitive position in the market. Meanwhile, the GMKtec Mini PC G3 S has a slightly better sales rank of 568. This suggests that while both products are popular, the G3 S may be favored among consumers seeking budget-friendly options. The sales performance can often reflect customer satisfaction and demand, making it an important factor to consider when choosing between these two models.

Which should you buy?

Choosing between the GMKtec M3 Ultra Mini PC and the GMKtec Mini PC G3 S ultimately depends on your specific needs and budget. If you require a high-performance machine for gaming, content creation, or professional multitasking, the M3 Ultra is the superior choice with its powerful Intel Core i7 processor, advanced graphics capabilities, and extensive connectivity options. However, if your needs are more modest, focusing primarily on routine tasks, office work, or home entertainment, the G3 S provides excellent value at a much lower price point. Consider what you need from your mini PC to make the best choice for your situation.
