MINISFORUM HX99G vs HX90G
Before the latest HX99G Neptune Series Mini PC came out, you might have had a look at the MINISFORUM HX90G beforehand. It is an almost identical Mini PC, but the differences are quite significant. We mean not only the processor but also the features of the device.
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 Mini PC 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.
The MINISOFRUM HX99G offers two SODIMM slots for up to 64GB of total DDR5-4800 dual-channel memory. 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.
HX99G supports quad display: two 4K/60 Hz displays through HDMI 2.0 and two 8K/60 Hz displays through USB 4.
