You can now buy Khadas VIM4 SBC for $199.90

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

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

Here is a reminder of the Khadas VIM4 specifications:

  • SoC – Amlogic A311D2 octa-core processor with 4 Arm Cortex-A73 cores at 2.2 GHz and 4 Cortex A53 cores at 2.0 GHz, Arm Mali-G52 MP(8EE) GPU, (Note: no NPU at this time )

  • Miscellaneous – RTC and Battery Header; 4-pin cooling fan header with PWM speed control; 3 user LEDs; power, function and reset buttons; XPWR pads for an external power button
  • Power – 5V to 20V via USB-C port or pogo pads
  • Dimensions – 82.0 x 58.0 x 13mm (4x M2 mounting holes)

Khadas VIM4 Heatsink

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

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

  • VIM Heatsink
  • 3705 Cooling fan
  • TS050 touch screen
  • New M2X expansion card for M.2 SSD and/or M.2 4G LTE modem
  • RTC battery
  • USB-C adapter
  • 4G module
  • 5G module
  • WWAN M2X
  • VBO-LCD module

On the software side, the 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 AOSP-based image without services like Google Play, but it offers features like display orientation, micro HDMI input, Wake -on-LAN, etc.

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

ODROID-N2+ vs. Khadas VIM4

If we compare the two platforms graphically, we can see that the memory bandwidth is much higher in Khadas VIM4, the 7-zip multi-thread score is also significantly higher, but AES-256 16KB is higher slow probably because it’s 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 the sbc-bench benchmark, I suspect Khadas could also deliver an image with higher DRAM timing if desired.

You can buy the Khadas VIM4 card now for $199.90 on the company store. But that’s without the recommended heatsink and fan, you might prefer to opt for the $219.90 “VIM4 Active Cooling Kit” instead. These are promotional prices with a $20 discount until June 10, 2022.
