Setup Notes and Platform Analysis
Upon completion of the hardware configuration of the review samples, we took some time to look into the BIOS interface of both systems. The videos below present the entire gamut of available options for both systems.
ECS has opted for a vanilla keyboard-only BIOS for the Z3. Available options include power management for resumption of the system by LAN / USB etc., control of resumption behavior after power loss, etc. These are key aspects for commercial deployments.
The ZBOX BIOS is comparatively more modern. The control of C-states, for example, is a lot more fine-grained compared to the LIVA Z3's.
AIDA64's system report provides insights into the platform for both systems. While the USB ports on the systems come directly off the PCH, it is still interesting to figure out the high-speed I/O distribution.
On the ECS LIVA Z3, the PCIe Gen 3 lanes are budgeted as below:
- PCIe 3.0 x1 port #4: In Use @ x1 (Intel Dual Band Wireless-AC 3165 AC HMC WiFi Adapter)
- PCIe 3.0 x2 port #5: In Use @ x2 (Crucial/Micron DM0182 NVMe SSD Controller)
- PCIe 3.0 x1 port #7: In Use @ x1 (Realtek RTL8168/8111 PCI-E Gigabit Ethernet Adapter)
The PCIe Gen 3 lanes in the ZBOX CI331 nano are used primarily for the LAN controllers, with the Wireless-AC 9462 connecting through the CNVi interface:
- PCIe 3.0 x1 port #5: In Use @ x1 (Realtek RTL8168/8111 PCI-E Gigabit Ethernet Adapter)
- PCIe 3.0 x1 port #6: In Use @ x1 (Realtek RTL8168/8111 PCI-E Gigabit Ethernet Adapter)
In today's review, we compare the ECS LIVA Z3 and the ZOTAC ZBOX CI331 nano with a host of other systems based on processors using the Atom microarchitectures. The systems do not target the same market segments, but a few key aspects lie in common, making the comparisons relevant.

The ECS JSLM-MINI is included to prove that the Z3's chassis design is solely responsible for performance loss under sustained realistic workloads. The ECS LIVA Z2 is included to obtain an idea of the generation-to-generation improvements, while the June Canyon NUC7PJYH is included to determine if the newer generation's fanless systems can compete well against the previous-generation's actively cooled flagship in the Atom-based product category. The next few sections will deal with comparative benchmarks for the above systems.

Correction (?)Neither of these reviewed products has a Intel UHD Graphics 605 .. (that's a 14nm Gemini part with 18 EU eg here https://ark.intel.com/content/www/us/en/ark/produc...
.. Intel seems to have not publisher a 'number' for this iGPU and seems to distinguish them by number of EU eg Jasper Lake 24EU eg https://www.intel.co.uk/content/www/uk/en/products...

Thanks for your coverage of fanless mini-PCs. However, I really wish you'd include something with "big cores", so we can get a sense of the scale of performance difference between them and Tremont.Another nice-to-have would be at least a few benchmarks including a Raspberry Pi 4. However, it has serious thermal throttling issues, unless it's actively cooled or you use a substantial passive cooling solution.

I guess the ideal comparison would be a Tiger Lake-based system, since that's the same vintage and similar manufacturing tech as Tremont. Probably much harder to find in a fanless mini-PC, unless we're talking about an industrial PC, but I'd love even to see a comparison between two NUCs: Tiger Lake vs. Tremont.mode_13h - Friday, July 8, 2022 - link
Or maybe Ice Lake would be even better, but did they make Ice Lake-based NUCs?abufrejoval - Thursday, July 14, 2022 - link
Yes, Tiger Lake NUCs were made, but also very hard to come by: I have both.In a way they are perfect to showcase the benefit of E/P cores …in the case of Intel: AMD is really another story.
The two NUCs look nearly identical on the outside, but inside they are very different beasts.
For starters: The Tiger Lake NUC11 (i7-1165G7 with 96EU Xe iGPU) is configured with a 64 Watt PL2, a rather long TAU and even the PL2 is 30 Watts by default, I believe. There is a reason it comes with a 90 Watts power brick! I changed PL2 to 50, TAU to 10 seconds and PL1 to 15 Watts to ensure the fan would never howl they way it does with the defaults.
I’ve seen HWinfo report a 5GHz maximum clock, but 4.7GHz is the official top speed. It’s at 64 Watts and near 5GHz clocks that I have measured 1707/5808 Geekbench 4 results on Linux (always a bit faster than on Windows). Jasper Lake doesn’t quite play in the same league at 781/2540 using 3.3 GHz and 10 Watts. In Watts/compute power Tiger Lake looks rather worse than Jasper Lake, but when it comes to rendering a complex web page or recalculating a giant Excel sheet, its sprinting power certainly has it appear much faster.
At 64 Watts the Tiger Lake is a desktop CPU, shoehorned into mobile power envelopes. And when it’s constrained to the levels that passive cooling can manage (see the Supermicro SYS-E100-12T-H review here), it really struggles to deliver that performance. The great thing about the Tiger Lake NUC is that you can change PL1, PL2 and TAU to pretty much anything you want and when you set it to the 10 Watts the Jasper Lake gets to use as an absolute maximum, it starts to do rather badly.
Some of that is because the iGPU always gets preference, leaving close to nothing to the CPU. But some of that is that the remaining power budget forces very low frequencies, where the big Core CPU loses against the Atom cores running at a full speed with these Watts.
Jasper Lake, like all the other Atoms since the J1900, never slows down. I’ve never seen it drop below its “Turbo” clock unless idle, even on a mix of Prime95 and Furmark, and I’ve never seen it exceed 10 Watts of combined CPU+GPU power consumption either.
I also have two Ryzen 5800U based notebooks (1443/7855 on Geekbench4), one of which can be switched between 15 and 28 Watts of TDP. When Tiger Lake and Zen 3 are strictly set to the same power levels, Tiger Lake has to run much slower even with half the cores: Ryzen beats it with a much smaller energy footprint per core. But with Tiger Lake left at the default NUC settings (which a battery powered notebook could not support), its four cores will beat an eight core Zen 3 at 15 Watts in Geekbench, which luckily never seems to exceed TAU.
Intel needs E/P because P cores need too much power at the clock rates they require to beat a Ryzen core, and only with E cores they can hit the efficiency of Zen cores in fully multi-threaded loads.

Wow, another awesome post! Thanks for taking the time to relate your findings. Very interesting!> the iGPU always gets preference, leaving close to nothing to the CPU.
Very key point, but also one that Intel could conceivably address, to some extent, in future BIOS updates. Not that they're likely to, if it had been on the market for a while when you tested, but it's conceivable.
> in Geekbench, which luckily never seems to exceed TAU.
Another great point! I have never run Geekbench myself, and I haven't noticed reviewers mention this key detail.

Zotac makes a fanless zbox with a 1165G7xol - Friday, July 8, 2022 - link
Benches I've seen suggest both are very similar in multi to a i3 low power Skylake eg a ie-6100T (2core 4 thread very common thin client chip) - the gfx capability also seems also a close match for the 24EU part [probably a very similar part with improved HEVC support] (the 32EU N6000 should be better)For single threaded the old Skylake is ~+50% faster., and from Skylake to Alder Lake it's nearly 2x , so nearly 3x from N5100 to i5-12500 for single thread
I have an old fanless Atom Z3735F (22nm) and these new SoCs are a impressive step up (~7x both cpu and gpu) -- I think the Pi Model B latest is very roughly 2x better than that nut no where near the 5100T in any metric.
tldr both benches would have been a wash one way of the other.
