Ever since consoles moved to the identical underlying structure as trendy desktop computer systems, there has all the time been an underlying query as as to whether those self same processors may run common desktop pc variations of Home windows, and subsequently be used for extra than simply gaming. We’ve needed to wait an extended whereas, however for no matter motive one of many 8th Technology Console processors is being enabled for the (mass) market, and the primary to leap on that recreation is the Chuwi Aerobox. We are able to set up Home windows, and it’s a loopy experience.
Set the Scene: Consoles on x86
The idea of the trendy console constructed on the identical x86 structure as desktop and gaming PCs got here into impact with the 8th Technology of consoles – we’re speaking the Ps 4 and the Xbox One, each of which used the semi-custom providers of AMD to construct particular processors for these machines.
These consoles initially got here to market in November 2013, inside every week of one another. Nevertheless, with a view to design processors for them, the design needed to start a number of years earlier, particularly when coping with each the character of console processor design, in addition to the {custom} additions that each Sony and Microsoft wished for his or her particular platform. On the time, Sony wished extra graphics {hardware} and used GDDR5, whereas Microsoft opted to allow high-speed eSRAM for its graphics as a substitute.
Because the design for these processors would have began within the 2010 timeframe, we’re nicely earlier than any desires of AMD designing Ryzen. On the time AMD had two CPU core designs that have been price some benefit: Bulldozer cores, with its 1 core/2 backend design that has since been branded a big dumpster fireplace for the corporate, or Jaguar cores, aimed extra for the low energy/excessive effectivity market. Weighing within the efficiency goal of this technology of consoles, each corporations selected having eight Jaguar cores.
Efficiency Dichotomy: Standardized vs Generalized
One of many key tenets for a console is a completely managed {hardware} ecosystem and software program stack. Although the {hardware} is constructed as a middle-of-the-road on the time of console launch, the console producer has full management over the software program, the virtualization, the drivers, and something additional particular embedded into the silicon. This permits recreation builders, and particularly recreation engine builders, to optimize their software program platform for a really strict {hardware} design. It additionally permits the driving force stack to be tremendous skinny, lowering latency and rising throughput.
That is completely different to the gaming PC market. As a result of a gaming PC can range wildly in processor efficiency, graphics efficiency, reminiscence efficiency, storage efficiency, and even community efficiency, any efficiency or constancy necessities on recreation builders for the desktop PC market are persistently shifting targets. We regularly discover that recreation builders will outline ‘minimal’ and ‘really helpful’ specs to get a desired stage of efficiency with a title.
It is vitally usually clear to see that over the lifetime of a console technology, builders will get extra out of the standardized {hardware} in a console than if it was the identical {hardware} in a generalized platform like a gaming PC. For this reason the 8th technology console market was in a position to make use of eight effectivity Jaguar cores, quite than going for the upper efficiency cores available on the market.
Which means if we get a console processor and use it in a gaming PC platform, there’s going to be a really distinct efficiency distinction. That is very a lot price bearing that in thoughts as we undergo this evaluate.
Enter the Chuwi Aerobox
To be trustworthy, I used to be stunned after we began listening to about numerous APU listings discovering their method onto benchmark web sites in early 2019. To begin with we noticed the A9-9820, then the RX-8150 and the RX-8120 pop-up, with core configurations and graphics counts close to to these of the Xbox One variants. There have been apparent rumors going round that an Xbox One-like PC design was within the wings, which clearly create a lot of questions as to the place the processors have been sourced, what the reminiscence configuration can be, after which subsequently if the efficiency was good or helpful. Ultimately a couple of leaked photographs of a possible motherboard got here to market on the time, and it was found that the producer Chuwi was behind it.
Chuwi is a system producer from China, and we’ve reviewed a very good portion of their {hardware}. The corporate jumped onto our radar in 2017, with the 14.1-inch Chuwi Lapbook, a low-end Netbook competitor. The Lapbook 12.3 a couple of months later attacked a extra premium market at an eyewateringly low worth, and ever since then Chuwi has been testing the market with some attention-grabbing and completely different designs. For instance, Chuwi was one of many solely corporations to allow Kaby Lake-G in a small kind issue PC (Kaby Lake-G was the place the place Intel paired its Kaby-H 45W processor with a semi-custom AMD GPU in the identical bundle, it was loopy), referred to as the Hello-Sport.
Now Chuwi was set to tempt us with this new ‘Aerobox’. To be trustworthy, over time, actual details about the Aerobox was skinny, and Chuwi weren’t making any public bulletins. We realized by way of numerous sources that the Aerobox was ultimately going to be focused on the Japanese market, which in itself is a really distinctive marketplace for PCs. In Japan there tends to be a skew for very small kind issue, esoteric builds, with the main focus way more on utility than efficiency.
We reached out to Chuwi in early 2020 for a pattern. Our contacts there defined that the Aerobox was not prepared for launch on the time, because it was going by way of a whole lot of revisions. We had no motive to not consider the corporate, nevertheless as months rolled on, there was part of me that has regularly puzzled if the explanation for the very long time between leak and launch (in addition to restricted launch within the JP market) was one thing to do with restrictions positioned on such a console processor being made accessible for the PC market. Both Microsoft didn’t need it out (or didn’t find out about it), or there was one thing else – maybe they have been ready for the brand new consoles to return out.
Up till August, I used to be emailing as soon as each 4-8 weeks, requesting an replace. As a result of our contact at Chuwi has modified about six occasions within the final two years, it has been troublesome to construct rapport with anybody particular person. That is vital as a result of usually an organization isn’t too eager on sampling a product exterior of its supposed gross sales area, as it will usually not be definitely worth the extra sampling overhead. It was that lack of rapport that was maybe behind the explanation why our Chuwi contact outright advised us that the corporate was not supposed to pattern exterior of the JP area. I pleaded the case for AnandTech, our distinctive fashion of protection, and our PR contact did a terrific job arguing the case internally, and we bought the thumbs from the Aerobox product supervisor. A number of weeks later, the Aerobox arrived. (Sadly it has been handed down my evaluate schedule a good bit with latest CPU launches and different protection needing consideration – I’ve provided my apologies to Chuwi for the delay.)
That is it. The Chuwi Aerobox is a small kind issue PC, designed to appear to be a console. The scale are similar to the older consoles, coming in at 288 x 236 x 50 mm, which is definitely barely smaller than the Xbox One S itself (295 x 229 x 64 mm).
Over the following few pages, we are going to tear down the unit, and in addition undergo some benchmarking. However first, what APU did we get?
What We Have: The AMD A9-9820
There have been three variations of the Xbox One: the unique Xbox One in 2013, the up to date Xbox One S in 2016, after which a better efficiency Xbox One X model in 2017. All three had eight Jaguar cores, however different in graphics cores, from 768 for the One and One S, as much as 2560 within the Xbox One X. The unique was constructed on a 28nm course of, with the One S and One X utilizing a superior 16nm FinFET course of.
The processor we now have in hand immediately can also be eight Jaguar cores, organized in two quad-core elements. Every half has entry to 2 MB of L2 cache, however the one overriding shared stage of reminiscence is within the DRAM. For different specs, this considerably of an oddball in comparison with the three processors that have been within the Xbox One collection. It’s virtually as if it’s a absolutely enabled model of Xbox One S, with elevated frequency and all of the graphics accessible. On this system the processor has the identify of A9-9820, and after poking for a couple of minutes, it does certainly seem like an overclocked full-fat model of the processor that went into the Xbox One, codenamed ‘Durango+’.

The Aerobox from Chuwi is utilizing this Durango+ processor. Throughout the eight Jaguar primarily based cores we see the elevated frequency on the CPU cores, from 1750 MHz to 2350 MHz, in each CPU frequency instrument we now have at hand. It retains this frequency at any load, for any size of time. By the identical token nevertheless, we appear to have additionally misplaced entry to the SRAM, making a fallback to eight GB of DDR3 reminiscence solely. This may have implications for reminiscence bandwidth.
To be clear, Jaguar cores are AMD’s low powered variant ‘cat’ cores, designed to compete with Atom cores. I’ve observed on-line that there’s some confusion on this, with some suggesting that these cores (and all Jaguar cores) have a Bulldozer-like design, which is inaccurate. Jaguar cores have shaped the spine of AMD’s embedded processor lineup for over a decade, designed for methods with 15-25+ 12 months lifecycles, with the G-series and R-series being probably the most profitable. These are present in any variety of embedded methods, equivalent to digital signage, industrial management electronics, and the slot machines in Vegas.
What We Have: AMD RX 350 Graphics…?
This A9-9820 APU contained in the Aerobox is listed on the principle product web page of Chuwi’s web site having R7 350 graphics, which might be the equal of a discrete desktop graphics card from 2016 with 512 streaming processors operating at 800 MHz (with 4500 MHz GDDR5 reminiscence). However the specs tab for the console lists it as having Radeon RX 350 graphics.
Nevertheless when the console arrived, on the field it stated the system had a ‘Redeon [sic] RX 350 collection’. Given the primary typo I used to be certain the second was a typo as nicely, on condition that the RX 350 didn’t appear to exist. Our system got here with Home windows 10 1903 pre-installed, and loading up our GPU recognition instruments solved a few of our questions, however raised some extra.
GPU-Z confirms that is an RX 350, referred to as Kryptos, however as a substitute of getting 512 streaming processors just like the R7 350, it has 896 of them. Be aware that the Xbox One S silicon as bought solely has 768. It is because bodily the Xbox One (and Xbox One S) truly had 896 streaming processors however a portion was disabled for the console with a view to assist with silicon yield (the identical factor has occurred with this latest technology of consoles as nicely). This goes alongside the absolutely enabled principle from the CPU part.
An attention-grabbing ingredient is that GPU-Z lists the sub-vendor as MSI, regardless of there being no point out of MSI wherever else on the product or by way of the stack. We reached out to Chuwi, who confirmed that MSI is the ODM for this board, and Chuwi is buying/sub-contracting the manufacturing from them. It makes me ponder whether it was Chuwi or MSI who managed to supply these processors, both from AMD or elsewhere.
Earlier than pertaining to the reminiscence, I need to point out the drivers. As talked about earlier, this method got here with a pre-installed Home windows 10 v1903, but additionally with preinstalled drivers. GPU-Z lists these as AMD’s Adrenalin 17.12 beta DCH drivers. We have been in a position to replace the OS with none points, nevertheless the drivers appear mounted – attempting to replace them yielded zero outcomes. AMD’s base software program doesn’t acknowledge this mannequin, not whilst an R7 350, and so for video games that require a minimal driver model this triggered points. Furthermore, chatting with different press which have a unique non-Chuwi model (extra on that later), they’ve been basically looking for wherever the place there have been any drivers that may very well be put in for these APUs. It seems there are driver packages that work on the market, however it’s a crap shoot. Even Chuwi’s personal web site doesn’t listing drivers. Some swift customers have discovered some sources, seemingly from one in every of MSI’s sub-contractors.
What We Have: Reminiscence Configuration
As for reminiscence, the A9-9820 right here makes use of DDR3. This confirms it as an Xbox One/One S variant, because the Xbox One X makes use of GDDR5, means we’re not coping with a cut-down model of that processor. With each the elevated CPU core frequency and graphics, little doubt energy consumption goes up as nicely. On the reminiscence, there are 4 modules of two GB DDR3-1333, for 8 GB complete, though it seems the system will take a complete of 16 GB if wanted. The modules utilized by Chuwi are low profile modules, maybe for thermals, however the system seems to take taller modules with none subject.
DDR3-1333 nominally creates 10.6 GB/s of bandwidth per channel. In our testing we scored round 14 GB/s, indicating we’re doubtless coping with a twin channel configuration. That is far, far decrease than the 68 GB/s that the consoles have from reminiscence, and even the 200 GB/s+ that the eSRAM would have offered.
Of the 8 GB of reminiscence within the system, this has to service the CPU and GPU, and Chuwi has set the system to robotically reserve 2 GB for graphics, leaving 6 GB for the working system and software program.
Why Console Processors Have By no means Made It To The PC Market Earlier than
The transfer of the console processors from separate architectures within the 7th Technology to x86 within the 8th Technology was a giant win for everybody. By having a standard structure between the 2 excessive efficiency consoles available on the market, but additionally parity with the main desktop gaming structure, it meant that builders would have a better time constructing a single recreation that focused all three platforms.
One would possibly argue that if these recreation builders have an excellent standardized {hardware} goal with a console, certainly there can be a profit to end-users if the identical {hardware} was accessible on the open market. There’s a motive why a whole lot of the tech press have content material constructed round ‘what an equal PC would appear to be’, as a result of the console {hardware} isn’t made accessible. In the end each Microsoft and Sony need to pull you into their ecosystem with tighter controls, and in the event that they bought the processors on the open market, another person would possibly provide a less expensive variant of the {hardware}, albeit on Home windows. After piling in these investments with AMD to create semi-custom silicon, but additionally to allow some type of safety by maintaining that ecosystem and firmware locked all the way down to the consoles solely, each Sony and Microsoft have all the time wished to maintain a really thick line between the console and the PC.
Over the following few pages, we are going to undergo the Aerobox system, how nicely it performs, plus some extra commentary on this market.
