Intel NUC5i5RYK Review: A Broadwell-U UCFF PC for Enthusiasts
by Ganesh T S on February 20, 2015 8:00 AM ESTNetworking and Storage Performance
We have recently started devoting a separate section to analyze the storage and networking credentials of the units under review. On the storage side, one option would be repetition of our strenuous SSD review tests on the drive(s) in the PC. Fortunately, to avoid that overkill, PCMark 8 has a storage bench where certain common workloads such as loading games and document processing are replayed on the target drive. Results are presented in two forms, one being a benchmark number and the other, a bandwidth figure. We ran the PCMark 8 storage bench on selected PCs and the results are presented below.
While the storage subsystem score doesn't bring out the efficacy of the M.2 PCIe SSD, the storage bandwidth number shows a chart-leading 322 MBps for the XP941 in the NUC5i5RYK. For good measure, we also ran the inbuilt benchmark in Samsung Magician (which doesn't support XP941 due to its OEM nature) to make sure that the SSD was utilizing the full capabilities offered by the PCIe lanes.
Sequential reads came in at 1 GBps and sequential writes at 716 MBps. Random accesses had upwards of 40K IOPS. All these point to the NUC5i5RYK possessing a ultra-compact platform with support for insanely fast primary storage media.
On the networking side, we restricted ourselves to the evaluation of the WLAN component. Our standard test router is the Netgear R7000 Nighthawk configured with both 2.4 GHz and 5 GHz networks. The router is placed approximately 20 ft. away, separated by a drywall (as in a typical US building). A wired client (Zotac ID89-Plus) is connected to the R7000 and serves as one endpoint for iPerf evaluation. The PC under test is made to connect to either the 5 GHz (preferred) or 2.4 GHz SSID and iPerf tests are conducted for both TCP and UDP transfers. It is ensured that the PC under test is the only wireless client for the Netgear R7000. We evaluate total throughput for up to 32 simultaneous TCP connections using iPerf and present the highest number in the graph below.
In the UDP case, we try to transfer data at the highest rate possible for which we get less than 1% packet loss.
Intel's AC7265 now behaves like a true 2x2 solution compared to the AC7260 in our testbed. While the numbers are not as good as those obtained with Broadcom-based 802.11ac WLAN cards, the improved performance is quite welcome.

No, the article is correct. 1st gen NUC was DCCP847DYE -- which was Celeron 847 -- Sandy Bridge based Celeron.Paapaa125 - Friday, February 20, 2015 - link
Gallery images have very bad underexposure problems. Please pay attention next time: you have to compensate exposure if you have too white background....piasabird - Friday, February 20, 2015 - link
It looks like all Intel did is take an i5 and underclock it down to about half the normal speed. I have an i3 4330 and it runs at 3.5 ghz and has the 4600 graphics and 4 megs of Cache. It runs great. I did turn the power supply that sits above the CPU so it pulls hot air out of the case. I run everything at stock speed with the CPU cooler Intel sold with the retail CPU package. No reason to purchase anything new.piasabird - Friday, February 20, 2015 - link
I liked the way you can select several similar comparisons to compare the review item to. However, I would compare it to a couple i3 processors that might typically be sold for Mini-ITX systems.Aikouka - Friday, February 20, 2015 - link
Does the Broadwell NUC still have the same issue with dropping bitstreaming when turning home theater devices (e.g. TV, AVR, etc.) off and then back on? I ended up getting rid of my Haswell NUC, because I needed something that was more reliable. Amusingly enough, my passively-cooled i3-3225 HTPC works great. It also lacks the weird issue where putting PLEX in the start-up folder on the NUC causes PLEX to improperly connect to the server -- you'd end up seeing the different libraries, but you could never browse them.CSMR - Friday, February 20, 2015 - link
Why isn't the HD6000 graphics with 48EUs dominating the HD5500 graphics with only 24EUs?TheinsanegamerN - Saturday, February 21, 2015 - link
My guess is a combination of lack of memory bandwidth and power restrictions. HD 4600 just barely maxes out 1600MHz memory, and 1866 is barely enough for HD 5500. HD 5200, the previous iris pro, had 72 GB/s of bandwidth, and still had bandwidth issues. 1866 ddr3 is nowhere near fast enough.The second thing is power consumption. HD 4600 in the i5 4300m pulls about 19 watts of power. now, hd 6000 has far more cores, 48 vs 20, which is still too much for 14nm to run on that little power. since the entire TDP is only 15 watt for that cpu, the GPU is both bandwidth restricted and power restricted.

The first NUC was IvyBridge, not SandyBridge.It was released in 2012

How did the Mainstream setup beat the Enthusiast configuration in the 7-Zip benchmark?!Is that a mistake? Should the labels be switched?

I love my NUC, barely 6W idling and 18W under load, surfs the net great, plays Netflix and YT videos great, plays my Steam games via in-home streaming perfectly.
