The ODROID H-series is growing with three brand new models

Again, the new generation is more powerful and offers higher performance. 
It also delivers key new IO that will please many users.

Introducing the ODROID-H4, H4+ and H4 Ultra

Hardkernel is introducing the ODROID-H4, H4+ and H4 Ultra, which is equipped with higher performance and richer interfaces.

 

The major characteristics of the ODROID-H4 series compared to the ODROID-H3 series are:

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, ODROID-H4+ and ODROID H4 Ultra only.
5. An additional DisplayPort added allows the simultaneous use of up to 3 monitors.
6. Low cost ODROID H4 for compute and graphics applications (e.g signage, robot, factory automation,..)
7. Flagship H4 Ultra doubling the number of CPU cores, from 4 to 8 cores.

We also implemented little details following the ODROID-H3 feedback we receive from all of our users, this means you. Examples: 

1. 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.
2. The new H4 cases format has been improved so that a cooling fan can be mounted inside the case.
3. A Mini-ITX kit for seamless integration with generic ITX PC cases.

Let’s look at the detailed table shown below.

Noteworthy Features

Why the N97 instead of the N100?

Bigger numbers aren’t always better. INTEL naming may be deceiving.

We chose the N97 because its Maximum Turbo Frequency is 200MHz higher than the N100, respectively 3.60GHz vs. 3.40GHz. In addition, the GPU Max Dynamic Frequency is a whopping 450MHz higher, respectively 1.2GHz vs. 750MHz.

The TDP value of the N97, which is therefore faster than the N100, is higher, but there is almost no difference in power consumption at idle state. Although the N97 is more expensive, we chose it for its higher performance.

Single-Channel Memory

This is a decision made by Intel. The Alder Lake N processors only offer one single-channel of memory. However, the DDR5 speed of 4800 MT/s as well as the Dual Rank (r2x8) option largely compensate for the double-channel of DDR4 with the H2 and H3 series. The DDR5 4800 MT/s of the H4 series leaves the DDR4 2933 MT/s and DDR4 2400 MT/s of the H3 and H2 series in its rear mirror.

Note: While the Intel ARK pages specify the Alder Lake N max. memory to be 16GB, we validated that 32 and 48 GB DDR5 SO-DIMMs 4800 or 5600 MT/s work as well. The 5600 MT/s will run at 4800 MT/s. The Intel specifications for the H2 and H3 processors were limited as well, but many users were able to (respectfully) pump up the max. memory to 32 and 64 GB.

How many SATA ports and video outputs?

Compared to the previous generation Gemini Lake or Jasper Lake, the design flexibility of the new Alder Lake-N’s high-speed signal interface has been significantly reduced. To enable SATA ports inside the SoC, a choice arose: reducing the number of PCIe lanes for NVMe from 4 to 2 or find another way. In order to avoid compromising the speed of NVMe, it was inevitable to add an external, expensive SATA controller.

Thanks to a controller that supports four SATA ports, the requirement to connect many storage devices has been resolved. As the performance of CPU, GPU, and DRAM increases, it has become possible to drive a large number of displays. Therefore, in addition to the one output each for HDMI and DisplayPort in the existing H series, the new H4 series is equipped with an additional DisplayPort, allowing a total of three 4K monitors to be connected simultaneously.

Because there are more connectors with relatively large footprints, the form factor has changed from 110x110mm to 120x120mm, and the area has increased by about 20%. As a result, form factor compatibility with the existing H2/H3 series has unfortunately disappeared. However, this affects only the case compatibility. Accessories such as the Net Card work on H2, H3 and H4 series.

Which H4 model is the best for you?

To allow you to use a high-performance platform at a relatively low cost, we removed all SATA functions, the second Ethernet port, and the Dual-BIOS feature to create a basic H4 model that focuses on cost-effectiveness. Therefore, it is suitable for application to embedded systems such as digital signage or factory automation or robot control.

On the other hand, the H4+ is equipped with four SATA ports, a second Ethernet port, and Dual-BIOS feature, making it the best choice for users who need mass storage for high-performance NAS and/or use it for routing capabilities.

Finally, although it is more expensive, we have also designed the H4 Ultra model, which can take advantage of powerful performance with twice the number of CPU cores (from 4 to 8) and more GPU execution units. Thanks to its many cores and fast clocks, the H4 Ultra model shows computing performance that can be twice as high as the H4 and H4+ models, based on multithreaded computing benchmarking results.

If you are very sensitive to power consumption, the H4 model would be the most desirable option. This is because the power in idle state is about 1 Watt lower than the H4+ model.

Performance

Thanks to the Intel Alder Lake-N Gracemont architecture, the higher frequencies of the N97, for the H4 and H4+, and N305, for the H4 Ultra, coupled with DDR5 4800 MT/s, the H4 and H4+ in UP mode are on average around 36% more performant than the H3+ in UP mode. The increased performance jumps to around 83% for the H4 Ultra, again compared to the H3+ in UP mode. This is what we witnessed while running 206 mostly non-synthetic benchmarks. We review these benchmarks further down. We will also see that the increased performance climbs to even higher numbers for multi-threaded applications.

Versatility

For the last 4 years, We acquired a lot of experience and feedback from users, meaning you, first with the H2 series, then with the H3 series. We have seen and still see an incredible broad range of applications.

Some users pushed their ODROID to the max with as much memory as possible, disks, discrete graphics cards, additional SATA ports cards or high-bandwidth network cards.

Conversely, other users made their ODROID as frugal as possible, chasing the last tenths of Watt that could be saved. In this matter, see section Power Consumption Characteristics, we worked on many aspects to make significantly low idle power consumption possible, as well as documenting and enabling users to know how to reach idle power that is not at all high compared to ARM series
boards. We believe this is essential, especially for European users where the cost of electrical energy has been rising for years, to which you add the goal of reducing net greenhouse gas emissions, as targeted by the EU, while running 24×7 systems.

These two extremes, and everything in the middle, are possible because the H series boards can be widely customized. We believe the success of the ODROID H-series is in part due to its original DIY design goal with boards that do not restrict you to one kind of application, e.g. TV box.

The ODROID H4 series doubles down on versatility by adding the low cost H4, with stripped down hardware, on one side of the H4+, and the 8-core H4 Ultra flagship on the other side of the H4+.

The table shown below details the H4 series user-level customizations:

Design	An SBC design that makes sense: all the connectivity is on the rear side, simplifying case design and reducing footprint on a desk.
H-series Net Card	Using the NVMe port, provides 4 additional 2.5 GbE ports, thus tripling the number of 2.5 GbE ports to 6 ports.
Do It Yourself	The ODROID H-series offers you a lot of freedom. You are free to chose: 1. The amount and brand of memory. No soldered memory. 2. The size of the eMMC (including not using one). No soldered eMMC. 3. The size of the NVMe PCIe Gen 3 x4 SSD, including not using one(*). 4. To transform the NVMe slot into a PCIe Gen 3 x4 slot for using PCIe cards via optional adapter cable(*). 5. The size of the 1 to 4 SATA III hard disks or SSDs, including not using them (H4+ and H4 Ultra only). 6. A case among 4 (soon to be 5) types of Hard Kernel cases or use a custom one you design or another user designed or use a mainstream Mini-ITX case thanks to the ODROID H4 Mini-ITX kit. 7. Hard Kernel cases allow the usage of an optional silent fan for optimal thermal performance. 8. Any x86-64 flavor of Windows, Linux or BSD operating systems, etc. 9. To upgrade the hardware later with larger memory, more NVMe or SSD or hard disk space. 10. To maximize performance or to minimize power consumption thanks to well documented BIOS and OS options. (*) PCIe Gen 2 on the H2/H2+.

Summary

Note: This summary compares the UP versions of the H3+, H4, H4+ and H4 Ultra because we did not run all the benchmarks on the H3+ non-UP. We ran a total number of 206 benchmarks/cases using the UP configurations.

The major facts about these benchmarks are:

• The H4 and H4+ UP are on average around 36% more performant than the H3+ UP.
• With the H4 Ultra UP, the average climbs to around 83%!
• The H4 and H4+ UP can be up to twice faster than the H3+ UP for particular tests.
• The H4 Ultra UP can be up to three and a half faster than the H3+ UP for particular tests.
• The H4 Ultra UP is on average around 36% more performant than the H4 and H4+ UP.
• The H4 Ultra UP can be more than twice faster than the H4 and H4+ UP for particular tests.
• Not too surprising, with 8 cores vs. 4 cores, the H4 Ultra UP top performance occurs with multi-threaded applications
  (e.g. Compilation, Java, Imaging, Stargate, MemCached, OpenSSL, Video Encoding,…) without being kneecapped by thermal throttling, thanks to Unlimited Performance and active cooling.

 

Demo video

This demo video shows the PS2 and GameCube emulation games on Linux Vulkan GPU driver with Fractional-Scaling technology. We used Batocera.linux x86_64 version 39 for the emulation.

Thanks to the H4’s significantly improved CPU, GPU, and DRAM performance, we can enjoy SD-quality classic masterpiece games in HD quality graphics now.  To play games with this level of graphics on the H3 board, we had to connect an external video card.
