SpecPicks Verdict

SpecPicks scored Bmax Mini PC B4 Ultra using a rating × review-volume × price-fit model applied to published specs and reviews across the home ai / computer lab category. Bmax's home ai / computer lab lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Key Features

INTEL N150 12TH GEN PROCESSOR – SNAPPY PERFORMANCE FOR EVERYDAY & BEYOND Powered by the Intel N150 12th Gen processor running up to 3.6GHz across 4 cores, the BMAX B4 Ultra handles everything from 4K media playback and web browsing to light office work and point-of-sale applications without breaking a sweat. Built on Intel's latest efficient architecture, it delivers noticeably smoother performance than previous-generation entry-level processors — all in a palm-sized form factor that fits anywhere.
12GB LPDDR5 RAM + 512GB SSD – FAST, RESPONSIVE, READY TO EXPAND With 12GB LPDDR5 4400MHz RAM and a 512GB M.2 SATA SSD pre-installed, the B4 Ultra boots fast and keeps applications running smoothly. When you need more room, a dedicated M.2 NVMe expansion slot supports up to an additional 4TB — perfect for storing 4K video libraries, security footage archives, or running local media servers. More storage flexibility than most mini PCs at this price point.
DUAL 4K@60HZ HDMI 2.1 – CRYSTAL-CLEAR VISUALS ACROSS TWO SCREENS Two HDMI 2.1 ports let you run two 4K displays simultaneously at a smooth 60fps, powered by Intel UHD Graphics. Set up a dual-monitor workstation for productivity, connect to your living room TV for a premium HTPC experience, or drive two digital signage screens at once — the B4 Ultra handles all of it without an external GPU. A USB-C port adds further connectivity flexibility for monitors and peripherals.
COMPLETE CONNECTIVITY – WIFI 5, GIGABIT LAN, BT 5.0, USB-C & USB 3.0 Everything you need to stay connected is built in Dual-Band WiFi 5, Gigabit Ethernet for wired stability, Bluetooth 5.0 for wireless peripherals, a high-speed USB-C data port, 2x USB 3.0, and 2x USB 2.0. Whether you're streaming content over WiFi, running a wired POS terminal, or connecting a full suite of peripherals, the B4 Ultra has a port for every need. Note USB-C supports data transfer only; video output via HDMI.
243G ULTRA-COMPACT WITH VESA MOUNT – SILENT, EFFICIENT, RUNS 24/7 Weighing just 243g, the B4 Ultra disappears behind any VESA-compatible monitor using the included bracket — zero desk clutter, clean professional setup. The pure copper heat pipe and smart cooling fan keep temperatures in check during extended operation, making it ideal for 24/7 use cases like digital signage, always-on media servers, and retail displays. Backed by a 1-year limited warranty and lifetime technical support from BMAX.
