Khadas has refreshed the VIM4, over a year after it released the single-board computer (SBC) with an Amlogic A311D2 chipset. While the chipset remains, it has been bolstered by a Neural Processing Unit (NPU). For some reason, Khadas elected against using the chipset's NPU with the original VIM4.
Surprisingly, Khadas has not unlocked the Amlogic A311D2's default NPU, which delivers up to 5 TOPS of performance. Instead, the new VIM4 features an NPU capable of delivering 3.2 TOPS. Other areas remain unchanged, such as the inclusion of 8 GB LPDDR4X RAM, 32 GB of eMMC flash storage, 32 MB SPI flash and a microSD card slot reader. Moreover, the VIM4 has an HDMI 2.1 port, a 40-pin header and an M.2 socket that supports PCIe 2.0 x1.
The new VIM4 starts at US$219.90, making it US$20 more expensive than the version without an NPU. Alternatively, Khadas sells the SBC with an active cooling kit for US$239.90, another US$20 surcharge over the equivalent model without an NPU. However, Khadas plans to discontinue the original non-NPU model once it exhausts current stock levels.
