Lichee Pi 4A RISC-V SBC surpasses Raspberry Pi 4 with TH1520 processor

The Lichee Pi 4A is a single board laptop (SBC) powered by . Alibaba T-Head TH1520 quad core RISC-V Xuantie C910 processor @ 1.8 GHz with Creativeness GPU and 4 TOPS NPU for AI that may compete with Raspberry Pi 4 by way of efficiency and options.

We’ve got already talked about about Lichee Pi 4A (LPi4A) in our article. System on Sipeed LM4A RISC-V module, however on the time we solely had some benchmarks for the motherboard and no images and specs concerning the SBC. Sipeed has now launched images and extra detailed specs and is “pre-ordering”. So let’s have a look.

TH1520 single board computer

The TH1520 was marketed as as much as 2.5 GHz, however now it appears to have dropped to 1.8 GHz. Software program help will embrace Debian, OpenWrt and Android within the first quarter of 2023 and extra working techniques might be supported as time goes on. Listed below are some benchmarks shared within the first announcement concerning the LM4A module, once more.

Dhrystone CoreMarks TH1520 RISC V and Raspberry Pi

Whether or not the Lichee Pi 4A or the Raspberry Pi 4A is quicker will rely on the actual utility as a result of the platforms are shut collectively within the imperfect Dhrystone and CoreMarks benchmarks. RISC-V efficiency is probably going to enhance because the software program ecosystem matures. Primarily based on the GFLOPS numbers offered within the specs, the Creativeness GPU must be sooner than the VideoCore VI, however we’re nonetheless not advised precisely which GPU to make use of.

Liche Router 4A

The corporate had already showcased a 7-module cluster board primarily based on LM4A on the time of the preliminary announcement, however they will even launch the Lichee Pi 4A SBC, 6-inch Lichee Telephone 4A and 10.1-based Lichee Router 4A. The inch Lichee Pad 4A is all geared up with the LM4A module.
