You can now buy Khadas VIM4 SBC for $199.90

Khadas VIM4 single board computer was first unveiled last October with Amlogic A311D2 octa-core Cortex-A73/A53 processor, 8GB LPDDR4X, but it’s only been launched today, and you can now buy the Khadas VIM4 board for right under $200.

It is an upgrade to Khadas VIM3 Pro launched with Amlogiv A311D hexa-core processor a few years ago, and our testing in Android 11 revealed the main benefit may be the upgrade GPU that delivered a 67% boost in 3DMark, but CPU multi-core performance and memory bandwidth will also see some benefits over Amlogic A311D, even against in overclocked systems like ODROID N2+.

Khadas VIM4 heatsink

My VIM4 board shipped with a heatsink and PWM fan that keeps it cool under load. It is turned off most of the time even in a room with a 28°C ambient temperature, and I found it very quiet when it is triggered under load.

The company also offers a variety of optional accessories, some of which you can find in our Khadas VIM4 unboxing:

  • VIMs Heatsink
  • 3705 Cooling Fan
  • TS050 Touch Screen
  • New M2X Extension board for M.2 SSD and/or M.2 4G LTE modem
  • RTC Battery
  • USB-C Adapter
  • 4G Module
  • 5G Module
  • M2X WWAN
  • VBO LCD Module
Khadas VIM4 Ubuntu 22.04

On the software side, Khadas VIM4 board supports the OOWOW system to easily download and install operating systems from the cloud, and currently lists Android 11, Ubuntu 22.04 Desktop, and Ubuntu 22.04 Server. The Android 11 OS is not designed for end-users with an image based on AOSP without services like Google Play, but it offers features like display orientation, micro HDMI input, Wake-on-LAN, and so on.

I’ve just installed Ubuntu 22.04 Desktop, and a full review is coming soon, but in the meantime, I ran sbc-bench.sh to compare it to the benchmark results I got with ODROID-N2+ (Amlogic A311D @ 2.4 GHz):

ODROID-N2+ vs Khadas VIM4

If we compare both platforms in graphical form, we can see the memory bandwidth is much higher in Khadas VIM4, the 7-zip multi-thread score is also significantly higher, but AES-256 16KB is slower probably because it is a single-threaded benchmark, and the Amlogic A311D2 Cortex-A73 cores run at 2.2 GHz, while the Amlogic S922X Cortex-A73 cores go up to 2.4 GHz in ODROID-N2+. With the CPU temperature never exceeding 58.2°C in sbc-bench benchmark, I suspect Khadas could also provide an image with higher DRAM timing if they wished to.

You can purchase the Khadas VIM4 board now for $199.90 on the company’s store. But that’s without the recommended heatsink and fan, so you may prefer going with the $219.90 “VIM4 Active Cooling Kit” instead. Those are promotional prices with a $20 discount until June 10, 2022.
