Chuwi UBook Pro: A big brother version of the MiniBook (UBook Review)

Not too long ago I have been using the MiniBook quite extensively till its battery died. But don't fret, it's still alive and well after replacing the battery couple weeks ago which I would like to add, that doing so was actually quite easy to do. Just ensure you have places where you can safely keep your screws. 

While I was having a battery problem though for a good month or two, I decided to give a big brother, UBook Pro a try. And while reviews on the Notebookcheck are average to bad, there are some very good things about it that make me wanna give a recommendation for.

Before we go any further, let's have a look at the specs. Some of the specs are shared while there are also some differences




CPU: Same. Core m3 8100y

To be honest, so far I am REALLY loving the m3 8100Y from the minibook's performance. Even though reviews have been mixed and criticized for its apparent lack of power. But for office, HTPC use, stuff like that, it's perfect for it, matching with other older Core i3s and Core i5s. So no worries there, at least from me.

RAM: 8GB vs 16GB

16GB had always been my standard. But the UBook uses 8 compared to the Minibook's 16. Sure more is better but I don't feel any significant performance hit. So I'd say 8GB on this for office use is perfectly fine.

SSD: 256GB SSD vs 128GB eMMC Storage.

Now this is where the biggest change is where I feel it makes the most difference. The SSD provided is not the fastest with read and write speeds around 250 and 280 MB Per second. However this is a true SSD instead of an eMMC storage. The SSD has like 30-40% faster transfers and that alone makes it pretty snappy on boot up.

Expandability and Serviceability:

In terms of that, the Minibook fares far better in the servicing and upgrading department. You need a pro to pry the UBook out. I can imagine you need quite a bit of time doing that. Having already serviced and replaced the minibook's failed battery very easily by myself is something. Both Minibook and Ubook can expand a Micro SD card slot. There is already an SSD as the boot drive for the UBook. But lucky for the minibook's case, the eMMC storage though slower, is separate from the SSD card slot. So you can further expand its mass storage to 512GB M.2 2242 based SSD Cards at the time of this writing, but can further expand once high capacity 2242s are in the market. With that aside from the eMMC slot, both storage slots can be expanded on the minibook, whereas you can only have 1 extra slot for the micro SD card slot.

Portability:

This one can be a debatable subject. Cause the minibook is obviously light at 660 grams. But that said, the Ubook, being about a full 12.3" display like almost double the size, it's not that much heavier, only by over a hundred grams, which 780g for a 12.3" Laptop not counting keyboard? Is nothing to sneeze at either. In fact the UBook is probably lightest in its class, could even possibly beat the MacBook Airs in terms of weight.

Add-ons

The Chuwi UBook has added on stuff that came with the tablet / laptop convertible. It came with a detachable keyboard dock which also includes a track pad. And a stylus can also be added if needed. The keyboard is average and alright for typical use, but man the trackpad is almost utterly unusable. The trackpad can be detected but sometimes will fail to pick up any gestures unless I detach and reattach the keyboard. A USB Mouse is definitely needed, thank goodness for additional ports.

Screen Resolution:

I'm not so fussed with the screen resolution because to be honest both displays are nice. Their resolutions are very similar, both at 1920 horizontally. The aspect ratio is what differs a tiny bit. The minibook stands at 1200 vertical, and 1280 at the Core Book. Not exactly a big difference and I can dig at both devices pretty nicely.

Ports:

Port selection is also near identical too. With 2 USB As, mini HDMI, 3.5mm Combo jack, USB-C. The only differences and feel that UBook has the edge is that the UBook Pro uses DC charge, freeing up the USB C port for other add ons. Additionally while the UBook's USB As are USB 3.0 standard, one of the Minibook's USB As are at USB 2.0. Still doesn't take away the fact that both devices offer pretty good IO. It would have been great a full HDMI port could have been jacked in there for both devices instead of Minis. My MacBook Pro is slimmer than than the minibook yet uses a full HDMI Port.

Which is better?

Gosh it is a close one, because  the Ubook's size is perfect size for Documents especially it's like near in line with A4 size sheet music which is perfect use on a regular basis. Whereas the Minibook has the serviceability, upgradability, and the smaller size to boot. Aside from the 8GB RAM difference, they perform similarly to each other.

I guess it will all depend on your use case scenario. Because each form factor has its use. Both are good devices in their tablet modes so do your research before deciding which of the two is best for you!

Minisforum Deskmini DMAF5 MiniPC on Indiegogo: Will it be the return of the AMD Brix Idea?

Just a couple months ago, Minisforum started to talk abit about releasing an AMD based APU MiniPC that could potentially rethink and refresh the idea of a MINI PC.

A few years ago, such tiny PCs were a thing, and to some degree, it still is today. But what the architecture of CPUs were back then were running too hot and running too slow. As demonstrated and reviewed in my Gigabyte BRIX back then, the AMD A8-5557M was hot, slow, and noisy. Not exactly what you want in an APU and even a small block PC.

http://paulstechinsights.blogspot.com/2015/04/review-of-gigabyte-brix-a8-5557-r9.html

Fast forward 5 years on since April 2015. I still think Small PCs have their place and can excel given the right environment and architecture. Today I have backed what would have been a worthy successor to the Gigabyte BRIX which I still have after reviewing that. It's by a company called MinisForum and their campaign on Indiegogo just went live a day or two ago.


And for everyone's info, I initially thought of myself more into gaming PCs. But lately not so, I'm a sucker for mini PCs. I have an Alienware Alpha, the aforementioned BRIX that is now upstairs in my brother's flat above mine, a Mini Chuwi Minibook. All good SFF machines. But I'd like to be sure that this one is a good one after I get mine from the campaign.



Now I know that Ryzen has already come out on smaller form factor PCs like the AsRock Desk mini A300 STX. However, this is the first time a company is putting that into a Brick Form Factor that's barely the size of your hand, maybe even smaller. And given how successful and how well Ryzen has aged over the last 2-3 years, now's the time to give this Super SFF idea a try again.

FEATURES


Specs
AMD Ryzen 5 3550H (4C8T)
2 SODIMM DDR4 RAM slots (starts at 1x8GB 2400 DDR4 Module, supports up to 2x16GB)
M.2 2280 nVMe SSD (Starts at 256GB)
2.5" SATA Bay (1TB HDD at stretch goal)
AMD Vega 8 Graphics (512 Stream Processing Units)
WiFi 6 Standard (Intel AX200)

Cutting short to the chase here, The tiny PC, codenamed the Deskmini DMAF5, is meant to be still upgradable, and easily serviced too. In a video with Linus Tech Tips, it just opens up with 2 press tabs to reveal the innards just by pushing the top of the device. It already starts off with a base 8GB RAM, and an M2 SSD. However you can still expand it even further with a 2.5" drive that can be installed in its bay as well as a 2nd SODIMM Slot for further increasing its RAM. On Indiegogo you can also top up the extra to have the 1st SODIMM slot taken by a 16GB RAM module instead, so it can go up to 32GB which is more than plenty for an office PC or HTPC. However it is a slower RAM kit at 2400MHz and being AMD, higher RAM speeds will affect user experience on AMD more than Intel does. I'm hoping that MinisForum will up RAM speeds to 2666 or 2800 MHz because this will also help graphics performance for the VEGA 8

The cream of the crop is the Quad Core SMT Ryzen APU / SoC. The 3550H. I know that the 4000 series is already in the market and wished that they update the models as such but the 3550H is still by no means a slouch of a Quad Core. And the fact that it does come with Ryzen VEGA 8 integrated Graphics means that it has some muscle for graphically intensive tasks. The 512 Stream Processing units on it should perform about as well as the intel's Iris 655 counterparts.

With that all said, the DMAF5 is said to be as comparable if not better than Intel's NUC offerings for a significantly cheaper price as shown in the comparison table below even if the dimensions are ever so slightly bigger. But being AMD, Thunderbolt 3 is absent which is a shame.


However your WiFi does get the WiFi 6 standard which increases efficiency over crowded areas. That's one of the features the competition, the NUC don't have. And also, thanks to overwhelming support, the SSD which was originally configured for SATA is now being tested for an NVMe upgrade. I don't usually fuss about SSDs being super speedy, but rather to ensure a snappy OS at the very least. But it'll be nVMe by the time this rolls out.

PRICE:

At time of this writing, the Super Early Bird of 399 USD is already gone, leaving the 429USD version in the Early Bird Pack. It's not exactly cheap but you're paying for that space saving feature. Lucky I was among the first 20 to back the Super Early Bird Perk which is pretty much the sweet spot for the PC. Initially the first 1500 Contributor IDs will receive an additional micro keyboard free. Not exactly the most usable add on but for a HTPC and a mini keyboard makes sense. This has been changed however thanks to a stretch goal, to a 1TB 2.5" HDD which is great. And the nVMe speed bump being testing is welcome at this price point.



COMPETITORS:

As far as competition goes, as of 21st August 2020, another of such device has appeared on the market. Beelink has entered the competition with a similar device with the same CPU.



Bottomline is you have an AMD equivalent of a NUC but slightly bigger, no thunderbolt but quite a fair bit cheaper with WIFI 6, nVMe. It can also be expanded and upgraded to some extent with more RAM and an extra 2.5" drive which is now a stretch goal already achieved. However as of this update on the 16th August 2020, you can also top up 40 USD for another 8GB of DDR4 RAM which I did and is actually quite reasonable and you don't need to fuss with RAM upgrades anymore. I know people with 16 can also up to 32 but I'm not sure as to how  much users will need to top up. It remains to be seen how well it will perform, which I will be testing for once it arrives in October. Also aforementioned with the hard drive, which means I don't need to tinker with the machine right out of the box!

I was regretting of not getting the Chuwi HiGame as it is more powerful in the gaming department. But the mini will to do.

TESTS ONCE IT HAS ARRIVED:

Gonna be a while till it does but my plan is to pit this against my Gigabyte P27G v2 Laptop that has been my bedside daily driver that recently has some plaguing issues especially when it comes to hibernating or turning off the hard drives. But also competing against some old scores that I have with the Gigabyte BRIX.

The laptop has the following Specs:
Core i7 4810MQ 4C8T
16GB DDR3 RAM
GTX 860M

Where the Gigabyte Brix has
AMD A8 5557M
6GB DDR3 RAM
Radeon R9 M275X / Radeon Mobility 8890M

Because my main idea of this miniPC is to see whether it can directly replace my Laptop and see how much better it is over the Gigabyte BRIX. Because CPU spec-wise they have the same number of cores but the BRIX's one doesn't have SMT and the architecture is way off compared to the Ryzen. The 5557M is based off of the Richland architecture, actually a derivative of Bulldozer which was quite bad. And now with Ryzen we'll see how it stacks up against my 4810MQ. Should be very similar! 
But we'll see!
