Gemini Lake SFF PC Showdown: Intel's June Canyon (NUC7PJYH) and ECS's LIVA Z2 Reviewed

This section looks at some of the other commonly used benchmarks representative of the performance of specific real-world applications.
3D Rendering - CINEBENCH R15
We use CINEBENCH R15 for 3D rendering evaluation. The program provides three benchmark modes - OpenGL, single threaded and multi-threaded. Evaluation of different PC configurations in all three modes provided us the following results.
The ECS LIVA Z2 suffers a bit in the OpenGL case, but, is neck and neck with the Arches Canyon NUC in the multi-threaded, and far ahead in the single-threaded case.
x265 Benchmark
Next up, we have some video encoding benchmarks using x265 v2.8. The appropriate encoder executable is chosen based on the supported CPU features. In the first case, we encode 600 1080p YUV 4:2:0 frames into a 1080p30 HEVC Main-profile compatible video stream at 1 Mbps and record the average number of frames encoded per second.
Our second test case is 1200 4K YUV 4:2:0 frames getting encoded into a 4Kp60 HEVC Main10-profile video stream at 35 Mbps. The encoding FPS is recorded. Unfortunately, both Gemini Lake systems were unable to complete this benchmark, exiting abruptly in the middle. The Arches Canyon encoded the 4K stream at 0.36 fps.
7-Zip
7-Zip is a very effective and efficient compression program, often beating out OpenCL accelerated commercial programs in benchmarks even while using just the CPU power. 7-Zip has a benchmarking program that provides tons of details regarding the underlying CPU's efficiency. In this subsection, we are interested in the compression and decompression rates when utilizing all the available threads for the LZMA algorithm.
In addition to the CPU, the RAM also plays a role here. ECS's decision to equip only one of the two SODIMM slots with RAM could be the culprit here.
Cryptography Benchmarks
Cryptography has become an indispensable part of our interaction with computing systems. Almost all modern systems have some sort of hardware-acceleration for making cryptographic operations faster and more power efficient. In this sub-section, we look at two different real-world applications that may make use of this acceleration.
BitLocker is a Windows features that encrypts entire disk volumes. While drives that offer encryption capabilities are dealt with using that feature, most legacy systems and external drives have to use the host system implementation. Windows has no direct benchmark for BitLocker. However, we cooked up a BitLocker operation sequence to determine the adeptness of the system at handling BitLocker operations. We start off with a 2.5GB RAM drive in which a 2GB VHD (virtual hard disk) is created. This VHD is then mounted, and BitLocker is enabled on the volume. Once the BitLocker encryption process gets done, BitLocker is disabled. This triggers a decryption process. The times taken to complete the encryption and decryption are recorded. This process is repeated 25 times, and the average of the last 20 iterations is graphed below.
Since all the considered CPUs have AES-NI capabilities, the above benchmark is representative of the sustainable clock speed and also the RAM characteristics.
Creation of secure archives is best done through the use of AES-256 as the encryption method while password protecting ZIP files. We re-use the benchmark mode of 7-Zip to determine the AES256-CBC encryption and decryption rates using pure software as well as AES-NI. Note that the 7-Zip benchmark uses a 48KB buffer for this purpose.
This shows that the relative numbers are similar to the ones observed in other benchmarks.
Yet another cryptography application is secure network communication. OpenSSL can take advantage of the acceleration provided by the host system to make operations faster. It also has a benchmark mode that can use varying buffer sizes. We recorded the processing rate for a 8KB buffer using the hardware-accelerated AES256-CBC-HAC-SHA1 feature.
Agisoft Photoscan
Agisoft PhotoScan is a commercial program that converts 2D images into 3D point maps, meshes and textures. The program designers sent us a command line version in order to evaluate the efficiency of various systems that go under our review scanner. The command line version has two benchmark modes, one using the CPU and the other using both the CPU and GPU (via OpenCL). We present the results from our evaluation using the CPU mode only. The benchmark (v1.3) takes 84 photographs and does four stages of computation:
- Stage 1: Align Photographs (capable of OpenCL acceleration)
- Stage 2: Build Point Cloud (capable of OpenCL acceleration)
- Stage 3: Build Mesh
- Stage 4: Build Textures
We record the time taken for each stage. Since various elements of the software are single threaded, and others multithreaded, it is interesting to record the effects of CPU generations, speeds, number of cores, and DRAM parameters using this software.
Stage 3 is likely memory performance-limited, unlike the first two stages that are reflective of the single-threaded performance capabilities.
Dolphin Emulator
Wrapping up our application benchmark numbers is the new Dolphin Emulator (v5) benchmark mode results.
This is again a test of the CPU capabilities, and the ordering expected based on the previous results is seen here too.

These aren't just light desktops, and perhaps you overestimate the size of the HTPC market.My employer actually uses NUCs for another purpose, entirely. A lot of things that would formerly be handled by lightweight servers can be done with a NUC. If you need to do some processing on-site (i.e. cannot move it into the cloud, or on a VM hosted by a big server), then NUCs are a pretty good option. I wish they had ECC, but it's not needed for our purpose (and there are industrial mini PCs that have it).

I agree with you that, for the use you describe, these NUCs are (almost, no ECC) perfectly fine. I disagree on underestimating the size of the HTPC market. Unfortunately, there are plenty of people who think hey, this could be a cheap solution for my media needs.I wish Ganesh would have put a clear statement in his review along the lines of " these units are okay or even excellent for situations where you need a compact PC that can run general office software or on-site processing. However, if you hope to put these Gemini lake systems to use as HTPCs, you're better off looking elsewhere" or similar.

To be honest, these have not really been positioned as HTPC, but as ultra-compact form-factor PCs. Other places describe it as a "PC replacement" or for "entry-level digital signage", e.g.:"The NUC7PJYH kit also comes with dual Ultra HD 4K display support via two full-sized HDMI ports, consumer infrared, and a TOSLINK audio jack, they’ve got everything they need to stream media, play, or finish that last-minute presentation. In addition, with 3.2x better graphics, you can create robust entry-level digital signage at entry-level prices for your SMB customers."
If you are looking for more in a NUC, and in particular HDR support, you probably want to be looking at Bean Canyon (CFL-U) or Hades Canyon (KBL-U) as described in https://www.anandtech.com/tag/htpc

The TOSLink port works perfectly under windows 10, with dd5.1 out.Oxford Guy - Friday, December 28, 2018 - link
"For example, in the average office scenario, it might not be worth purchasing a noisy and power-hungry PC just because it ends up with a 2000 score in the SYSmark 2014 SE benchmarks. In order to provide a balanced perspective, SYSmark 2018 also allows vendors and decision makers to track the energy consumption during each workload. In the graphs below, we find the total energy consumed by the PC under test for a single iteration of each SYSmark 2018 workload. For reference, the calibration system consumes 5.36 Wh for productivity"versus 6.03 for the LIVA and 6.60 for the NUC. So, they both fail the office work test. That is not what I expected nor what most would expect, since Atom in particular is supposed to be more, not less, energy-efficient for things like office work. Is it due to the i3-7100 being able to finish tasks more quickly, a storage speed bottleneck, or both? I assume it's the first one.
It's also rather sad how slow these are when compared with Piledriver parts in the Cinebench tests. Even single-threaded Cinebench, which exposes how slow Piledriver is when compared with Intel's real CPUs, makes these low bad. The multicore performance is pitiful. Yes, I realize that Piledriver uses more energy. However, a processor like the 8370E is hardly an energy nightmare if it's not overclocked and it kicks the tar out of these chips (100 for single-threaded and 614 for multithreaded). The 8320E was ultra cheap at MicroCenter and even qualified for the motherboard price reduction. Color me underwhelmed when a design from 2011/2012 that wasn't much of an upgrade when it came out manages to greatly outperform parts being sold on the cusp of 2019, without using a tremendous amount of energy. Clearly, an officer worker would be happier with an 8320E than one of these CPUs and it's not even for sale anymore — let alone a Sandy Bridge chip which has better single-threaded performance.
These boxes, then, seem to be for more niche activities, like HTPC use.

"makes these low bad" unfinished sentence... oops: "Makes these low low end chips seem particularly bad."speculatrix - Monday, December 31, 2018 - link
I bought a June Canyon NUC specifically because of the TOSLink optical output. I can vouch that, with the right drivers under windows 10 you can get Dolby Digital out, when playing Netflix from the Netflix app, or movies with the right audio codecs with VLC.pseudoid - Wednesday, January 23, 2019 - link
I thought I was in the PC aisle of Fry's Electronics store. Yeah, here it is 2019 and they are still trying to offload the NUC7s at retail prices. I bought NUC8s (one w/i5 and the other with the i7) in December 2018 and I'm tickled pink.haralake - Friday, September 3, 2021 - link
Hello! I would like to power NUC7PJYH NUC after a power failure. Specifically I want to use a mini ups with 12v 2a 30watt output. I read in the model information that 12-19v power supply is possible on NUC7PJYH, so I will not have a problem with 12v. But I would like to know if the 2a and 30watt provided by my ups are enough for NUC7PJYH.
