From Tom's Hardware: RISC-V-based processors have been making inroads into a wide range of applications, from tiny microcontrollers to data center processors. However, RISC-V hasn't been used for many consumer or gaming devices (except, perhaps, in the form of the microcontrollers mentioned above). Sipeed is a Chinese company trying to change that with its Lichee Pocket 4A console, one of the industry's first RISC-V-based handhelds, targeting mobile gaming.
Sipeed officially positions the Lichee Pocket 4A as a "RISC-V Debian+Android RetroGame platform." As the name suggests, it's designed to run simplistic retro games using GPU acceleration or even software rendering. The unit uses the LM4A system-on-module based on Alibaba's T-Head TH1520 RISC-V processor. It packs four RISC-V Xuantie C910 general-purpose cores running at 2.50 GHz and an unknown Imagination GPU.
The system-on-chip was originally designed for laptops, so it should be moderately powerful — at least powerful enough to run simple retro games. The device can run Google's Android or Debian operating systems and should potentially support the majority of games for those OSes. Meanwhile, it's unclear how many true retro games (which were developed, say, for DOS) can run on these platforms.
The Sipeed RetroGame platform can be equipped with a 7-inch 1280x800 LCD touchscreen, 8 or 16 GB of LPDDR4X memory, and 32GB or 128GB of eMMC storage. It also has Wi-Fi + Bluetooth 5.4 wireless connectivity and a plethora of wired connectors (USB 3.0, USB 3.0 Type-C, GbE, and a 3.5-mm headphone jack). The unit weighs 490 grams, which is significantly below the weight of Valve's Steam Deck, though much of the difference likely stems from the cooling and battery used on the Steam Deck.
