Following their initial reveal at CES 2026, ASRock has now published the full technical specifications for its new flagship NUC Ultra 300 series of mini-PCs. The new devices are poised to set a new standard for performance in a compact form factor, combining the latest Intel “Panther Lake” Core Ultra processors with powerful graphics and advanced connectivity options.
Next-Generation Performance
At the heart of the series are the latest chips from Intel. ASRock offers two key configurations aimed at different user segments, built around the new Core Ultra Series 3 processors.
Flagship Power: Core Ultra 7 and Arc B390 Graphics
The top-tier model is equipped with a 16-core Intel Core Ultra 7 X358H processor, which includes 4 Performance-cores, 8 Efficient-cores, and 4 Low Power E-cores for an optimal balance of power and consumption. Its main feature is the discrete Arc B390 graphics with 12 Xe cores. According to preliminary tests, its performance is on par with, and in some cases exceeds, the GeForce RTX 4050 Laptop GPU, making this mini-PC capable of handling modern games and demanding professional workloads.
The Balanced Solution: Core Ultra 5
A more modest version features an 8-core Core Ultra 5 325 processor with integrated graphics based on four Xe cores. The company claims the performance of this iGPU is comparable to the AMD Radeon 760M, which will be sufficient for everyday tasks, multimedia, and light gaming.
Compact Design, Maximum Capabilities
ASRock stays true to its tradition of compactness by offering the devices in two chassis options: the classic NUC Box at 49mm height and the ultra-slim NUCS Box at just 38mm. Despite their miniature sizes, engineers have managed to pack in an impressive set of components and ports.
- Memory: Support for up to 128 GB of DDR5-7200 RAM.
- Storage: Two M.2 slots for SSDs, one of which supports the ultra-fast PCIe Gen 5 x4 standard.
- Ports: A modern USB4 port, USB 3.2 Gen 2×2 Type-C, and two HDMI 2.1 video outputs.
- Networking: Dual 2.5 Gbps Ethernet ports in the NUC Box version (one in the NUCS Box) and the latest wireless module with Wi-Fi 7 and Bluetooth 6 support.
Future Outlook and Market Perspective
The ASRock NUC Ultra 300 series is a prime example of how the lines between mini-PCs and full-fledged desktop systems are blurring. The mini-PC market is experiencing explosive growth, driven by the shift to remote work and the demand for powerful, energy-efficient solutions. Competition in this segment, which already includes strong players like Minisforum, Beelink, and ASUS, is becoming increasingly fierce. ASRock’s offering, with its RTX 4050-level discrete graphics and PCIe Gen 5 support, could be a serious contender for leadership. However, the key factor for success will be the price, which remains unannounced. If ASRock can offer a competitive price point, the NUC Ultra 300 has every chance of becoming a hit among enthusiasts and professionals seeking maximum performance in a minimal footprint.
