From a MINISFORUM press release:

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 8GB) 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 PCIe4.0 SSD (up to 2TB) slot, an extra M.2 2280 SSD slot (Support NGFF SATA or NVMe PCIe4.0 SSD) is also provided for expansion.
