MINISFORUM HX99G 6900HX + RX 6600M Mini PC

Minisforum introduced a new variant called HX99G in its Neptune portfolio today. It is an upgraded version of the first member, the HX90G (5900HX processor + RX6600M GPU), which was announced in May 2022 before going up for sale in September 2022. The Neptune HX99G looks practically identical to the HX90G. Measuring 205 x 203 x 69 mm (8.1″ x 8″ x 2.7″), both models feature 45 watts, 8-cores/16-threads graphics and the same laptop-class discrete GPU. However, it updates the Ryzen 9 5900HX with a faster Ryzen 9 6900HX and replaces the two DP ports with two speedier USB4 ports.

R9 6900HX integrates all eight cores based on the Zen 3+ microarchitecture. It’s clocked at 3.3 (guaranteed base clock) to 4.9 GHz (max boost). Ryzen 6000 brings a slew of technological advancements, like support for USB 4, PCI-E Gen 4, DDR5-4800MT/s, WIFI 6 and Bluetooth 5.2. The other AMD performance component is the RDNA 2 graphics architecture Radeon RX 6600M (GDDR6 8 GB) with a TDP of up to 100 watts. Users can expect to utilize the full performance of this dedicated GPU to handle professional-class photo and video editing as well as content creation. Also, this GPU packs enough firepower to hit 60 frames per second at 1080p (depending on the specific game and settings).

HX99G adopts the same cooling solution as the HX90G. It has 7- heat-pipes (3 for CPU and 4 for GPU) and dual fans inside. The computers use liquid metal on the CPU and GPU and have cases that incorporate carbon fiber. The excellent heat dissipation design enables the HX99G to maintain relatively low noise even under full load.

As for the storage, users can build their own RAM up to 64 GB. Besides the default M.2 2280 PCIe 4.0 SSD (up to 2 TB) slot, an extra M.2 2280 SSD slot (Support NGFF SATA or NVMe PCIe 4.0 SSD) is also provided for expansion.

HX99G supports quad display: two 4K/60 Hz displays through HDMI 2.0 and two 8K/60 Hz displays through USB 4. Other ports include:

  • Power Button
  • USB 3.2 Gen1 Type-C Port
  • Microphone Jack
  • Headphone Jack
  • USB 3.1 Gen1 Type-A Port
  • RJ45 2.5 Gigabit Ethernet Port
  • USB 3.2 Gen2 Type-A Port x 3
  • Power Supply

The price for barebone (No RAM, No SSD and No OS) starts at USD$839. Minisforum offers up to 64 GB RAM and 1 TB SSD configuration options.
