Intel NUC 13 Pro Arena Canyon Review: Raptor Lake Brings Incremental Gains
by Ganesh T S on March 27, 2023 9:00 AM ESTSystem Performance: Multi-Tasking
One of the key drivers of advancements in computing systems is multi-tasking. On mobile devices, this is quite lightweight - cases such as background email checks while the user is playing a mobile game are quite common. Towards optimizing user experience in those types of scenarios, mobile SoC manufacturers started integrating heterogeneous CPU cores - some with high performance for demanding workloads, while others were frugal in terms of both power consumption / die area and performance. This trend is now slowly making its way into the desktop PC space.
Multi-tasking in typical PC usage is much more demanding compared to phones and tablets. Desktop OSes allow users to launch and utilize a large number of demanding programs simultaneously. Responsiveness is dictated largely by the OS scheduler allowing different tasks to move to the background. Intel's Alder Lake processors work closely with the Windows 11 thread scheduler to optimize performance in these cases. Keeping these aspects in mind, the evaluation of multi-tasking performance is an interesting subject to tackle.
We have augmented our systems benchmarking suite to quantitatively analyze the multi-tasking performance of various platforms. The evaluation involves triggering a ffmpeg transcoding task to transform 1716 3840x1714 frames encoded as a 24fps AVC video (Blender Project's 'Tears of Steel' 4K version) into a 1080p HEVC version in a loop. The transcoding rate is monitored continuously. One complete transcoding pass is allowed to complete before starting the first multi-tasking workload - the PCMark 10 Extended bench suite. A comparative view of the PCMark 10 scores for various scenarios is presented in the graphs below. Also available for concurrent viewing are scores in the normal case where the benchmark was processed without any concurrent load, and a graph presenting the loss in performance

| UL PCMark 10 Load Testing - Productivity Scores | |||
| UL PCMark 10 Load Testing - Essentials Scores | |||
| UL PCMark 10 Load Testing - Gaming Scores | |||
| UL PCMark 10 Load Testing - Overall Scores | |||
All PCMark 10 workload components see the relative ordering being maintained even after the addition of the concurrent loading.
Following the completion of the PCMark 10 benchmark, a short delay is introduced prior to the processing of Principled Technologies WebXPRT4 on MS Edge. Similar to the PCMark 10 results presentation, the graph below show the scores recorded with the transcoding load active. Available for comparison are the dedicated CPU power scores and a measure of the performance loss.

Despite a 50% performance loss, the NUC13ANKi7 retains a signficant lead over the other systems in webXPRT4 in the presence of the transcoding workload.
The final workload tested as part of the multitasking evaluation routine is CINEBENCH R23.

| 3D Rendering - CINEBENCH R23 Load Testing - Multiple Thread Score | |||
We see a 60%+ drop in the single thread case, and a 40%+ drop for the multi-threaded case, but the raw numbers are still well in favor of the NUC13ANKi7.
The latest version of Windows 11 (22H2) apparently has some additional thread scheduling improvements that can help Alder Lake and Raptor Lake deliver better / more balanced performance for multi-tasking scenarios. We may get a chance to evaluate that a few quarters down the line.

If you're just looking to dabble, you might check out Apple's Refurbished shop. I swear by their shop and use it to help my parents getting inexpensive iDevices as they don't need the latest and greatest.They tend to sell pretty lightly used machines that are only a generation or two old at decently discounted prices. If you buy a laptop or other mobile device, I believe that all 1st party Apple Refurbished devices get a brand new battery as part of the refurb process.
FWIW, it looks like through the refurb site you can get an M1 Mac Mini with 16GB RAM and 512GB SSD for $809. Yes, you lose out on the improvements that the M2 brings, but it saves you almost $200 too.
The M1 is going to be plenty potent compared to your... Core2 Duo(?) based Macbook?

If you can't stomach apple's prices, check out refurbished/lightly used apple gear on backmarket or, for older machines you can upgrade yourself, Ebay. Apple's official refurb store is great but you will never get more than about 15% off there. I love my apple gear, but I only ever buy used/refurb, because I cannot afford the price Apple charges for new.Affectionate-Bed-980 - Tuesday, March 28, 2023 - link
For how "dead" Anandtech has been in terms of publishing GPU and CPU reviews, I'm surprised we get a NUC update and full review before this is even available for consumers!abufrejoval - Tuesday, March 28, 2023 - link
My NUC10 seems to just have burned through its Thunderbolt port: for some weeks it's lost the connection to the Sabrent/Aquantia 10Gbit NIC after a couple of days, but power cycling brought it back. Now it's just gone completely, just can't seen anything connected on TB any more.So while I needed a replacement, NUC12 is still rather expensive and I am still yearning for something Mini-ITX not NUC anyway, I hit across this one: https://elchapuzasinformatico.com/2023/03/cpu-inte... which is much cheaper than a comparable NUC of that generation.
So I just decided to order one to see if it holds water. I won't be able to reuse the RAM, but with 64GB at €120 that's no longer a pain point and it is a bit more flexible and expandable than the NUCs, while unfortunately it lacks the TB port, but will allow me to use one of my AQC107 PCIe x4 NIC in storage.
Mini-ITX with one of my Noctuas allows to raise the sustained TDP to 35 Watts without getting annoying, while idle power consumption might not be very different. That's my main beef with desktop based Mini-ITX hardware, I want the lowest idle power and then "comfortable" peak performance without getting distracted by noise, heat or electric bills.
H- and P-class SoCs from AMD and Intel basically allow that, but are hard-to-get in these smaller form factors: high-end notebooks obviously represent the more attractive sales channels and older parts are leak into these Chinese surplus channels only when laptops have switched to the next generation.

IMHO one of the biggest missing elements for several generations now has been lack of ECC support. With both "normal" and inline ECC most likely being included in the silicon, it's really just market segmentation again and a reason to go with Ryzen, if ECC support on their APUs wasn't such a lottery game, too.64GB is half a billion bits where things can go wrong and I just like the odds less and less...

@abufrejoval: I agree 100%. ECC DRAM is the single most important hardware feature that most people need but don't have a clue about. I curse Intel for segmenting it out of existence, and AMD for not promoting it. May the world wake up...Anyone know of a small form factor / NUC like computer with ECC support? Intel's NUC 9 Pro / Quartz Canyon from 2019 is the only one that I can readily find.

I'm not sure the price/performance is here for this one vs chips like 6800HX with a much better igpu. That said two thunderbolt ports are very interesting for my use case and would be the best feature.abufrejoval - Tuesday, March 28, 2023 - link
I see the 96EU Xe doing 5-25% better than the 5800U iGPU and iGPUs typically get Wattage priority over CPUs so a "H" class iGPUs don't do better than "U", no matter if I operate the SoC at 15-28 (AMD) or 15-64 Watt (Tiger Lake NUC).So the 6800 generational uplift may just put AMD ever so slightly in the lead again, but in a race of sloths vs turtles.
For TB I keep hearing that many of the USB4 ports on AMD APUs are actually TB capable and only lack certifications... Have not had a chance to verify that.
I can't mix AMD and Intel in my clusters, so it's too late for me to switch. But the other thing is that I needed 10Gbit and for that TB sadly was a must, because for some crazy reason vendors believe 1/2.5Gbit is adequate for NVMe systems.
I've wanted mobile SoC based mainboards with PC type flexibilty for years, but only some crazy Chinese companies are selling that.

Sadly, as someone who has built my own systems going back to 486 CPUs and outrageous fast wide SCSI and a super expensive video card.I think the days of building desktop PC is in it's last days.
Most people are going to only need small nuk sized units that will do most of what they need.
abufrejoval - Tuesday, March 28, 2023 - link
I can beat that, started with an 80286 (actually with an Apple ][ clone before that) and SCSI fast, wide or dual channel came much later, it was MFM and RLL before, using PIO, because the 8-bit DMA from the original PC simply wasn't fast enough for anything beyond floppy. BTW that system cost me more than a new middle class car would have and the people and shops selling them, would reflect that (suits, ties and talk): Those weren't just another microwave like box at the mall.Yes, after more than 4 decades the PC era is drawing to a close, but I'm not sure it's from lack of scale at the desktop: it's ARM from above and below that will spell the end of the x86 evolution.
There are way more PC enthusiasts today than there were PC users when we got hooked and custom builds just never scale: IKEA!
To me the real successor of the PC is the smartphone, but only if it isn't actually an Apple or Google remote control.
