Geekom XT12 Pro review: Stylish NUC mini-PC alternative with Intel Core i9-12900H, 32 GB DDR4 RAM and 1 TB SSD

The Geekom XT12 Pro uses the same wireless module as the Geekom A7. The MediaTek Wi-Fi 6E MT7922 WLAN module does not achieve the best values but is sufficient for data transmission in normal use. If possible, the 6 GHz frequency range should primarily be used. The difference in performance compared to the somewhat slower 5 GHz frequency range is already noticeable when transferring a lot of data. Alternatively, the Geekom XT12 Pro can also handle a wired network connection. Data rates of up to 2.5 GBit/s are possible here.

The Intel Core i9-12900H is based on the Alder Lake architecture and combines 6P and 8E cores. Together, this provides the user with 20 threads. Even after more than two years, the SoC is still not outdated, and in comparison, we see a reasonable gap to the more modern AMD Ryzen APUs.

In terms of power limits, Geekom limits the Intel Core i9-12900H to a maximum of 80 watts, although 35 watts are permanently available. However, we did not reach the maximum value at any time. We can already state this at this point. In the test, we often only see around 60 watts, which means the manufacturer is not exploiting the full potential here. Nevertheless, the SoC is operated in accordance with the manufacturer's specifications, as 35 watts are permanently available. In the duel with the competitors, our test sample often has to admit defeat. The same picture can be seen in the AIDA64 benchmarks. The disadvantage of the older DDR4 memory becomes apparent here.
