Intel NUC5i5RYK Review: A Broadwell-U UCFF PC for Enthusiasts
by Ganesh T S on February 20, 2015 8:00 AM ESTPerformance Metrics - I
The Intel NUC5i5RYK was evaluated using our standard test suite for low power desktops / industrial PCs. We revamped our benchmark suite early last year after the publication of the Intel D54250WYK NUC review. We reran some of the new benchmarks on the older PCs also, but some of them couldn't be run on loaner samples. Therefore, the list of PCs in each graph might not be the same.
Futuremark PCMark 8
PCMark 8 provides various usage scenarios (home, creative and work) and offers ways to benchmark both baseline (CPU-only) as well as OpenCL accelerated (CPU + GPU) performance. We benchmarked select PCs for the OpenCL accelerated performance in all three usage scenarios. These scores are heavily influenced by the CPU in the system. The Core i5-5250U is obviously not as powerful as the Iris Pro-equipped Core i7-4770R in the BRIX Pro. However, note that the M.2 PCIe SSD and the faster DRAM (despite the lower latency) help the enthusiast configuration take a handy lead over the mainstream configuration in all the PCMark benchmarks.
Miscellaneous Futuremark Benchmarks
PCMark 7 seems to favor the Core i7 models much more compared to the PCMark 8 benches. However, even in this suite, the enthusiast configuration performs better (similar to what we saw in the previous sub-section). The faster memory also helps the GPU post better scores under the enthusiast configuration for the 3DMark benches. Surprisingly, HD 6000 doesn't perform better than the HD 5500 in the Broadwell BRIX s when the 3DMark 2013 scores are considered. However, 3DMark 11 clearly favors the HD 6000.
3D Rendering - CINEBENCH R15
We have moved on from R11.5 to R15 for 3D rendering evaluation. CINEBENCH R15 provides three benchmark modes - OpenGL, single threaded and multi-threaded. Evaluation of select PCs in all three modes provided us the following results.
As far as 3D rendering goes, the Broadwell-U NUC really doesn't provide any great benefits compared to the Haswell-U NUC. Faster memory helps with the multi-threaded and OpenGL-accelerated rendering a bit, but, other than that, there is really not much to talk about with this benchmark in terms of performance improvement.

I wouldn't. The GPU on the low end APU's isn't *that* much better than intel's IGP and the TDP's are too high, which is a big consideration IMO for a device that may spend quite a lot of its time running. I've found my Celeron G1820 system to be superior in every way than the A4 system it replaced, except in casual gaming where they both were basically useless. The CPU gap can absolutely be relevant when you start messing with different decoders as well.yankeeDDL - Friday, February 20, 2015 - link
The laptop is a Lenovo Z50, with Kaveri's A10-7300. With default settings, I haven't found a game which is not playable yet. And it costed me nearly half the NUC in this article ($400).Regarding which HTPC to buy, I was looking into Zotac's: something to stash behind the TV, away from view.
I agree with you that the savings on low-end AMD APU's are not worth it: the A10 is already dirt cheap.

I just recently bought the Z50-75, lovely machine for the price. 19W CPU in a 15.6" chassis is great for low fan speed and cool operation, even when it's turbo'd up at 3.2GHz. I don't rate it much for games though as it is not powerful enough to drive 1080p without dialling back the quality settings.cjs150 - Friday, February 20, 2015 - link
owan et al: I have owned AMD machines before, and will probably do so again in future. The problem is TDP, they run too hot. In my main HTPC I run an i7-3770T (45w TDP). More than sufficient power for transcoding. When I built that machine, AMD had nothing even close. The problem with going fanless is heat, and AMD are way behind on this.HTPC use is very personal. I do not want to go 3D and 4K is currently unnecessary. But it may be that h.265 codec is too CPU intensive for what I have. If so then I will build new machines - but as that will probably be several generations of CPU in future, it is not a problem (and when it is, it will be fun to build!)

To each its own. It's good to have choices :)seanleeforever - Friday, February 20, 2015 - link
cjs150: try amd 5350 APU. i run it without fan, it is a 25W TDP SOC (so all the IO memory controllers on build on the processor with Radeon HD 8400 ).i too find this review lacking to say the least. i build ultra small factor PCs for fun, and i have yet to find one that beats AMD's offering for general windows use in a ultra tiny factor.
the only three issues with AMD solutions is
1. driver under linux are not that great, but it is getting better.
2. smallest form factor is ITX, which is still too big ESPECIALLY consider 5350 is a SOC.
3. stock cooler sucks. it has the worst oem cooler i see in my entire life.

hate to tell you, but the 5350 is NOT an SoC. It is just a low TDP CPU, because the memory is still external. the memory needs to be in the chip in order for it to be considered a SoC. an integrated memory controller has been standard from 7 years, that doesnt make the chip a SoC.And ITX isnt too big. you can build mac mini type systems in that size. anything small is proprietary, and OEM only. see the NUC above. you cant by a motherboard for that.

the name "SoC" means a number of things, i suppose you could say it is not SoC by your standards but many website (Anandtech, the one you are commenting on, says "...Athlon 5350, a quad core SoC"), similarly, if you define SoC as something that must have on board memory by design, then you can pretty much rule out all the snapdragon processors since they don't have on board memory. So i would like to believe your definition is flawed, as so will most people.secondary, you are dead wrong about it is just a low TDP CPU. go research the 5350 Spec, one thing it stands out is that not only does it have memory controller, but it also feature a video controller , TPM, PCIe lans, Sata port, VGA output, USB3 and USB2, and PS/2 all on the CPU. the thing about SoC is that it is a System on Chip (minus other stuff like storage, ram, power...etc). it has all the I/O (south bridge), and memory controller (North bridge) all build in one die. this is more similar to cell phone processor than traditional computers. this allows M/B to pretty much just bring out pinouts.
i suggest you to know your subject before posting. this is anandtech and i do expect user to have some basic knowledge in the comment section.

TheinsanegamerN -- NO Processors have all the memory built in -- The most memory you can get is on Crystalwell, but thats still cache. In phones you get PoP which means Package on Package, meaning a SoC underneath and then a regular memory chip on top.A CPU is generally considered a SoC when it requires no north bridge or south bridge, ie it has memory controller, pcie controller, usb, sata, GPU, etc.

That AMD 5350 APU still has a weak CPU. Also its 25W thus it should not be run without fan. That's why the stock cooler has a fan. And due to that weak CPU, it has problems with higher resolution videos: http://www.guru3d.com/articles_pages/amd_athlon_53... quotes"We also tested Ultra HD video acceleration. Above the 4K resolution Elysium Trailer, here we have an MP4 H.264 file and you can see that the CPU load is 52% with one core topping out performance. Unfortunately Ultra HD videoplayback resulted into stuttering. For both content we have additional shaders enabled like image sharpening and darkened black levels.
The reason why we noticed stuttering seems to be that the trailer is not DXVA encoded. meaning of you where to RAW decode video streams over the CPU, it would not be powerful enough. The GPU at DXVA will take care of you on that here though."
