This mini PC looks strongest as a compact emulation and light gaming box, with the Ryzen 7 6800H and Radeon 680M handling MAME, Batocera, light gun games, and even some PS3 or Teknoparrot titles at 720p. It is also described as very fast for daily use and quiet in normal operation. The main knocks are the lack of Thunderbolt, Oculink, and dual LAN, plus reports of driver setup hassles and past company support or malware concerns. A solid fit if you want small size and strong integrated graphics more than expansion features.

  • The 680M integrated graphics can deliver strong real-world performance for retro and light gaming workloads.

  • The mini PC can handle light gun gaming up to PS3 and Teknoparrot at 720p without issues.

  • The system can be useful for emulator and arcade builds or for an IT lab tinkering setup.

  • The unit can run quietly in a typical room setup, with noise only possibly noticeable when pushing workloads.

  • The hardware lacks Thunderbolt and Oculink support, which limits hub stations and component sharing options.

  • The iGPU performance can land around an RX 6400 or GTX 1650 level, which may feel limiting for heavier games.

  • Gaming performance can be mixed, with Diablo 4 nearly unplayable unless settings are dialed back.

  • The listing can be inaccurate about dual LAN support, which can affect networking expectations.

I bought the Firebat a6 as well. I mainly use it for batocera. I think all the USB A are 5Gbps, but the USB C is probably 10Gbps since it was comparatively faster. You also can get video out of its USB C which I use with Rayneo air 3s pro glasses. In my limited testing it seems happiest around 1440p which was tested with GameCube rogue squadron II. I didn't mess much with rpcs3 because when I upscale on different machines I get graphical glitches in batocera. Lollipop chainsaw massacre the characters turn to green static. It's fine if I keep it native resolution. If this box is like the firebat a6 it only came with one stick of ram which will hurt iGPU performance since it's only single channel.
I use the USB C for my external SSD and just one screen via HDMI. I have a dual boot set for the light gun games in Batocera running off the SSD, and then windows for Retrobat with non light gun games.

From what everyone told me about the 680m, I am getting much better performance. It's probably because I am not trying to upscale PS3 to 4K, and not dealing with more modern gaming. But the single stick or DDR5 Ram has been more than enough for me.

I got very lucky on Black Friday by stacking Aliexpress coupons and also the PayPay $40 off. For $220 this more than suites all my needs and the 780m really doesn't seem like much of an upgrade

Just my theory…. People claim higher RAM price because companies hoarding RAM to build AI in their data centers. If that was the case, why prices of other components not went up the same rate since last summer? Are they building PC without CPU, SSD, GPU (or NPU), etc. ?
For consumer PCs, RAM is measured in GB. For data centers, try TB.
