2026 verdict
Does the GMKtec NucBox G3S (8GB + 256GB) beat a 13th Gen Core i9 anywhere but price?
The Geekom IT13 (2TB) carries a higher owner rating, triple the warranty coverage at three years against one, quadruple the memory and eight times the storage, and a Core i9 13900HK built for the kind of 4K editing, DAW work and local AI use the GMKtec NucBox G3S (8GB + 256GB)'s four-core N95 cannot take on. What the GMKtec NucBox G3S (8GB + 256GB) offers instead is a genuinely low entry price for a licensed Windows 11 Pro machine that still covers browsing, documents and streaming without complaint. Choose the Geekom IT13 (2TB) for serious multitasking or creative work with room to spare, and choose the GMKtec NucBox G3S (8GB + 256GB) for the cheapest capable mini PC in this pairing.
