The Odroid H4-Ultra. The most powerful H-Series board on the market, and the highest benchmarked x64 unit we have ever produced. This is a beast of a device, and is the flagship model of the new-generation H4 Series of boards. 

The Odroid H4-Ultra wields an Intel Core i3 N305 processor, accepts up to 48GB of DDR5 SODIMM RAM, and has options for Dual BIOS installations, making for a beefy as well as safe computing environment.

It is equipped with four SATA ports, and a second Ethernet port, making it the best choice for users who need mass storage for high-performance NAS and/or use it for routing capabilities.

It has the power to emulate complex hardware - the video below shows 60FPS emulation of PS2 and Gamecube with upscaled native graphics - it is our best x64 / x86 unit.

Top Line Feature Set Compared to the Odroid H3+:-

  1. Faster CPU architecture - Alder Lake N vs. Jasper Lake. Plus AVX2 extensions.
  2. Faster DRAM interface DDR5 4800 MT/s vs. DDR4 2933 MT/s.
  3. Higher base and boost CPU frequencies and more powerful iGPU.
  4. The increase from 2 to 4 SATA ports allows connection to a greater number of storage devices.
  5. An additional DisplayPort added allows the simultaneous use of up to 3 monitors.

We also implemented little details following the ODROID-H3 feedback we received from all of our users. Examples of this are: 

Dual BIOS: If the BIOS is corrupted due to a power outage during update, etc., you can boot into the backup BIOS and recover by moving the jumper next to the DC jack. This feature is only available on ODROID-H4+ and ODROID H4-Ultra.
