Jasper Lake and Alder Lake-N in a Smaller-than-UCFF Package

Compact computing programs have gained vital market share during the last decade. Enhancements within the efficiency per watt metric of processors have enabled the substitute of cumbersome desktop PCs by ultra-compact form-factor (UCFF) machines with a 4 in. x 4 in. footprint. Motivated by IoT purposes on the edge, some corporations corresponding to Shuttle began creating x86 programs in sub-4×4 form-factors utilizing Intel’s Apollo Lake processors. ECS was one of many first mainstream distributors to concentrate to this section with their LIVA Q Sequence utilizing Intel’s Atom collection and AMD’s first-generation Ryzen Embedded SoCs. With the introduction of extra power-efficient platforms, Asian producers corresponding to ACEMAGIC, GMKtec, and MinisForum have additionally entered this micro-PC market with a wider vary of processor decisions.

For the reason that introduction of Silverthorne Atom processors in 2008, Intel has been sustaining separate microarchitectures in several product households to span a wider efficiency / energy effectivity vary. In consequence, shoppers may both go for a low-power low-cost platform sacrificing on efficiency with Atom-class CPUs or go for a extra performant Core-class CPU, albeit at the next price with some sacrifice on the facility effectivity entrance. From 2008 to 2020, these remained distinct product households. Nevertheless, the introduction of hybrid CPUs (beginning with the short-lived Lakefield) noticed cores primarily based on each microarchitectures to be positioned on the identical die. The Tremont microarchitecture (developed as a part of the Atom-family) made its debut in Lakefield earlier than gaining wider market presence by means of Jasper Lake, Elkhart Lake, and different product households. Its successor (Gracemont) is adopting the same trajectory. After its introduction in Alder Lake, it underwent additional refinement in Raptor Lake.

Intel launched the Alder Lake-N (ADL-N) product household to take over Jasper Lake’s position within the cost-conscious low-power PC market. It’s basically an Alder Lake processor with all of the efficiency cores eliminated, and a pared-down built-in GPU. As ADL-N ramps up and Jasper Lake winds down, we’re seeing merchandise primarily based on each households being actively bought available in the market. We took benefit of this chance to supply two micro-PCs – the ECS LIVA Q3D, and the ACEMAGIC T8 Plus – and put them by means of our analysis routine to check the advantages of ADL-N’s Gracemont microarchitecture over Jasper Lake’s Tremont. This evaluation presents an in depth evaluation of the outcomes together with a dialogue of the tradeoffs concerned in pursuing a smaller-than-UCFF footprint.

Introduction and Product Impressions

Developments in processor energy effectivity and efficiency have resulted in sub-15W TDP SoCs turning into highly effective sufficient to interchange cumbersome desktops for a lot of use-cases. Intel’s NUC lineup kickstarted this pattern within the early 2010s, with the 4 in. x 4 in. ultra-compact form-factor (UCFF) turning into the de-facto commonplace for such programs. This dimension was arrived at holding the I/O necessities, disk drive sizes, and ease of board design / meeting in thoughts. Since that point, each storage and reminiscence applied sciences have advanced considerably. Most programs use M.2 SSDs these days, a marked shift from the two.5″ drives widespread in these days. Whereas SODIMMs proceed to be the selection for programs providing reminiscence improve capabilities, trendy processors have began to combine LPDDR4 / LPDDR5 assist. This has resulted in plenty of programs with soldered reminiscence on board. These components have contributed to some distributors making an attempt to experiment with micro-PCs – programs having a sub-4×4 footprint.

ECS LIVA Q3D

ECS has remained commited to micro-PCs because the introduction of the Apollo Lake-based LIVA Q1L. The corporate has adopted it up with the LIVA Q2 primarily based on the Gemini Lake refresh SoCs, the Q3 Plus primarily based on the first-generation Ryzen Embedded SoCs, and most not too long ago, the Jasper Lake-based LIVA Q3D. In comparison with a standard UCFF system, the LIVA Q3D collection makes a few tradeoffs. As a substitute of SODIMMs, the system makes use of soldered LPDDR4X RAM. A M.2 SSD slot is averted by integrating an eMMC boot drive on the board. That is complemented by a built-in microSDXC card reader. These enable the LIVA Q3D to be very compact. The 74mm x 74mm x 34.6mm (a quantity of simply 0.19L) system weighs simply 174g.

Along with the principle unit, the LIVA Q3D package deal comes with a VESA mount and corresponding screws, and a 36W (12V @ 3A) wall wart. The ability adapter has a replaceable plug, and ECS supplies US, UK, and EU adapters. The gallery under supplies a complete take a look at the chassis design and I/O ports placement. The teardown footage supplies insights into the internals of the unit.

The teardown footage within the above gallery present that ECS has adopted a dual-board technique for the system. Whereas the principle board has the SoC package deal, RAM, and eMMC, together with the audio jack, the daughterboard has the entire different I/Os together with the USB and LAN ports.

A stable warmth sink is mounted with screws on prime of the Jasper Lake package deal, and complemented by a 40mm Cooler Grasp blower fan to take out the warmth in typical pocket book fashion. The CMOS battery is sandwiched between the 2 boards and a metallic protect ensures electrical interference mitigation between the elements on the 2 boards.

ACEMAGIC T8 Plus

The T8 Plus is ACEMAGIC’s first try at making a micro-PC. Just like the ECS LIVA Q3D, the T8 Plus additionally makes use of soldered RAM. Nevertheless, due to the newer reminiscence assist in ADL-N, the board adopts LPDDR5 RAM. A semblance of upgradability is maintained, due to using a M.2 2242 SATA SSD as a boot drive. The 89.4mm x 89.4mm x 43.4mm (0.35L) system weighs 205g.

Along with the principle unit, the T8 Plus package deal comes with a HDMI cable, wall mount with related screws, an person handbook, and a 30W (12V @ 2.5A) geo-specific wall wart. The gallery under supplies a take a look at the chassis design and I/O ports placement. Teardown footage offering insights into the internals are additionally included.

The photographs present the presence of a raised section on the underside. This round section additionally consists of perforations that enable for cool air to be drawn in earlier than exiting by means of the copper warmth spreader’s fins. In contrast to the LIVA Q3D, the T8 Plus makes use of a single board design.

The RAM and the SoC package deal are underneath the warmth sink / followers, whereas the M.2 2230 slot for the WLAN / BT card, and the M.2 2242 SATA SSD slot are on the opposite aspect (nearer to the highest panel). The pre-installed SSD is from FuturePath, however we had been unable to make out the title of the controller producer regardless of the provision of the emblem within the closing image of the above gallery. The CMOS battery and the WLAN antennae are affixed to the underside of the chassis prime panel.

Each programs got here prepared with Home windows OS pre-installed. The complete specs of the 2 evaluation samples (as examined) are summarized within the desk under.

Within the subsequent part, we check out the system setup and observe it up with an in depth platform evaluation.
