Llano Mini-ITX mobo face off: Asus F1A75-I Deluxe vs. Zotac A75-ITX WiFi a tale of two tiers by Geoff Gasior — 1:38 PM on October 5, 2011

AMD’s latest mainstream desktop platform boasts arguably the most potent two-chip combo in the industry. At the head, you’ve got an A-series APU powered by the latest Llano silicon, which offers four reasonably fast CPU cores backed by a DirectX 11-class Radeon that puts competing integrated graphics solutions to shame. Baby’s got back, too. the tail end features a Hudson-based platform hub that’s loaded with 6Gbps Serial ATA and USB 3.0 connectivity. No other tag team offers such a cutting-edge array of baked-in goodness, making this Lynx platform perfect for the next wave of small-form-factor systems.

If you want to roll your own mini PC, you’ll be needing a Mini-ITX motherboard. our first instinct would be to look to Zotac, which is largely responsible for reinvigorating interest in the decade-old Mini-ITX form factor. over the past few years, Zotac has rolled out a number of attractive Mini-ITX motherboards based on the latest chipsets and sockets. Indeed, the company’s Z68-ITX WiFi earned a TR Recommended award when we dissected it back in July.

As you’ve probably guessed, Zotac has cooked up a new Mini-ITX board built just for AMD’s A-series APUs. the A75-ITX WiFi offers all the perks associated with the newest Fusion platform, plus additional wireless amenities. and it’s not alone. the recent popularity of midget motherboards has attracted the attention of Asus, which has designed its own Mini-ITX home for Llano: the F1A75-I Deluxe. Naturally, we couldn’t resist pitting these two contenders against each other in a featherweight cage match.

Zotac’s A75-ITX WiFi motherboard the Mini-ITX form factor is Zotac’s adopted home turf, so it stands a better chance against Asus than one might expect given where the two companies sit among the multiple tiers of motherboard makers. Asus is the biggest name in the retail motherboard market, while Zotac is at best a second-tier player. Zotac made its name inside small-form-factor systems, and the A75-ITX is designed to fuel the next generation.

The board itself looks relatively sedate. Although the overall aesthetic isn’t particularly eye-catching, Zotac deserves credit for deviating from the black-and-blue color scheme that has permeated the bulk of new motherboard designs.

Small-form-factor systems present particular challenges when it comes to component clearances. as you can see, the A75-ITX’s various slots and ports are snuggled right up next to the CPU socket. To provide a better sense of how much room there is to spare, we busted out a ruler to measure a few key clearances.

There’s only 17 mm of space between the CPU socket and the closet DIMM slot. Depending on your CPU cooler, that arrangement could complicate compatibility with taller memory modules. the VRM and chipset heatsinks put more distance between themselves and the socket, and they’re only about 30 mm tall. Only the most overgrown CPU coolers are likely to restrict access to the PCI Express x16 slot located at the far edge of the board.

The more than three-inch gap between the socket and the x16 slot is densely populated, even if its inhabitants are relatively stunted. on the far left sits a front-panel USB 3.0 connector. beside it, an AzureWave Mini PCIe card bestows the board with 802.11n and Bluetooth 3.0 wireless functionality.

Over to the right, we see Zotac is only taking advantage of four of the six SATA ports built into the A75 chipset. that should cover the storage needs of most small-form-factor systems, but the top-right port is a little too close to the CMOS battery. the vertically mounted battery is tall enough to interfere with the locking tabs on Serial ATA cables—including the ones that come in the box—so you’ll want to keep a small, flat-headed screwdriver handy.

We can follow the wireless card’s loose, looping wires all the way to the port cluster, where they’re anchored to a pair of antenna jacks. the wiring is awkwardly bent around the heatsink fins it touches—not a big deal, but amateurish when compared with what you’ll see on the next page.

With the exception of internal headers for a pair of old-school USB 2.0 ports, the rest of the A75-ITX’s USB connectivity is of the SuperSpeed variety. Counting the internal headers and the six ports in the rear cluster, there are twice as many USB 3.0 ports as are available in the A75 chipset. rather than relying on third-party controllers to supply the additional ports, Zotac splits the ones coming off the A75 using a pair of USB 3.0 hubs from via. These VL810 hubs are capable of splitting one USB 3.0 port into four, but it’s unclear which of the A75-ITX’s ports stem from the hubs and which, if any, are linked directly to the chipset. We’re still waiting on Zotac to explain how everything is connected.

For all four of you who want to build a Llano-based NAS box, the A75-ITX serves up a pair of Gigabit Ethernet ports backed by Realtek controllers. Realtek also provides the audio codec, an ALC892, which fuels five analog audio jacks and a digital S/PDIF output. if you’re short an S/PDIF input on your speakers or receiver, multi-channel digital audio can be passed through the HDMI port by Llano’s integrated Radeon.

Zotac ties the Radeon to DVI and HDMI outputs. a CMOS reset switch is tucked just to the left of those display ports in the rear cluster. the button might seem like a minor addition, but anyone who has ever tried to get at the CMOS reset jumper in a cramped Mini-ITX enclosure will definitely appreciate it.

Although the A75-ITX has one of those newfangled UEFIs, you wouldn’t know it by using the thing. There’s no mouse support, the graphical interface looks exactly like an old-school BIOS, and the array of tweaking options is limited. Short of an APU multiplier setting that’s largely useless until AMD releases unlocked Black Edition versions of Llano, the UEFI is pretty much devoid of overclocking options. you can crank the memory clock to 1866MHz, but that’s about it. Even the voltage options are extremely limited—in both scope and granularity.

Overclocking a small-form-factor Llano box probably wouldn’t be wise. however, you’re definitely going to want to tune that system’s fan behavior to make it as quiet as possible. the UEFI doesn’t do too poorly on this front, offering the ability to set a starting temperature threshold, plus starting and maximum speeds for the CPU fan. one can also switch the CPU fan into a manual mode locked at a static speed. Separate controls aren’t provided for the system fan, though.

PREVIEW On one hand, the HP TouchPad faces an uphill battle in the tablet market because Apple’s iPad has been such a hit with the public and continues to gain momentum. on the other hand, the TouchPad has a great opportunity because the iPad’s current rivals — Android tablets and the BlackBerry PlayBook — haven’t exactly set the world on fire, and Microsoft and Intel haven’t shown up yet with a true iPad competitor.

after working with the TouchPad for a week, I’m ready to declare it the iPad’s stiffest competition yet for individual business professionals, who currently represent a quiet but very large portion of the iPad user base. the TouchPad is no match for the iPad when it comes to media, entertainment and games, but for those who want the portability of a tablet but the work ethic of a desktop, the TouchPad has raised the bar on productivity.

Who is it for? the TouchPad will mostly appeal to professionals who want a tablet to handle work tasks — web-based business apps, email, instant messaging, contacts, calendar and so on. These will mostly be executives, project managers, IT administrators and other businesspeople who want to purchase their own tablets and use them for work.

What problems does it solve? one of the biggest unsolved problems in tablets has been content creation and productivity. the iPad’s great strength is its singularity of focus. the app experience is immersive. but, the flip side of that is that it’s not very good at multitasking — it’s simply not designed for it. the BlackBerry PlayBook and Android tablets have tackled the issue and made some progress, but they haven’t gone as far or done it as elegantly as the TouchPad, which allows users to group open apps and windows into logical groups, quickly separate, reorder or close them, and jump between them with the flick of a finger. the excellent on-screen keyboard (including number keys) and the wireless dock and wireless keyboard make it easier to enter data on the TouchPad than other tablets. All in all, these productivity improvements make the TouchPad the most effective notebook replacement of any of the current tablets.

Standout features Multitasking Where the TouchPad really shines is in the interplay between multiple apps, multiple windows within the same app and multiple browser tabs. When most professionals do work, they need to access multiple data streams at once and synthesise that information into a document or email message, and while they’re doing it they may need to call, text or IM a colleague to ask a question or get some data they’re missing. in the middle of all that, they may also receive a message where they need to respond to someone else’s question or issue. with its notification system, multitasking and smartphone/tablet interaction, the TouchPad is designed to help these types of knowledge workers be (nearly) as productive on a tablet as they are on a notebook or desktop.

Full web experience the TouchPad also offers web browsing that gets a lot closer to the desktop web experience than the iPad. a lot of that has to do with its Flash capabilities, but it also handles some other interactive web code better than the iPad, even though both are based on WebKit browsers. I’m not a fan of Flash but much of the web is still based on Flash, and will be for years to come. the TouchPad offers a much better Flash experience than the buggy Flash you’ll find on Android tablets, but it’s not quite as smooth as the excellent Flash experience on the BlackBerry PlayBook. of course, the iPad does not support Flash at all. an example of how the TouchPad also works on some sites where the iPad does not is WordPress, the popular blogging tool. I actually started this review of the TouchPad on the TouchPad itself in the WordPress web interface — which does not work on the iPad.

Smartphone interaction Most of the professionals who have a tablet also have a smartphone and there are times when it gets clumsy and confusing as to when to use which one for which task. HP has addressed this by letting you pair an HP smartphone with the TouchPad. I tested this with the Pre3 and was pretty impressed. It allows you to take a call received on your phone and bump it over to speakerphone on the tablet or take a text message from the phone and bump it over to the tablet’s instant messaging app. There’s also a feature called Touch-to-Share that allows you to take a web page that’s open on the TouchPad and share it to the smartphone by simply touching the phone to the tablet. this is fairly rudimentary stuff and it’s limited to HP phones, but it’s nice start in bridging these two devices in some meaningful ways.

Email app one of the iPad’s worst features (from a business perspective) is the native email app. using the app in portrait mode is especially clumsy, and moving between a message you’re composing and a message in your inbox means having to save the message, access your information and then reopen your message from your drafts to finish it. the TouchPad streamlines that process with its multitasking capabilities and provides an email app that makes it a simple finger flip on the bottom of the screen to move from various email accounts and folders to your inbox/folder message list to a full-screen view of a message.

What’s wrong? Inconsistent performance My biggest beef with the TouchPad is performance. It has a 1.2GHz dual-core Qualcomm Snapdragon CPU and 1GB of RAM, so it’s got the hardware to really move, and there are times when it flies between tasks and apps and runs great. However, there are also times when it unexpectedly chugs, freezes or gets really slow. I never had it crash, but there were 8-10 times over the period of one week where it slowed to a halt. That’s too many. I suspect this is a software issue and asked HP about it. the company responded that performance improvements are part of an over-the-air update for the TouchPad that will arrive after launch.

Bulky form factor the look of the HP TouchPad echoes the first-generation iPad. It has the same rounded corners and curved backplate, only it’s black instead of silver and plastic instead of aluminium. of course, by the time the TouchPad landed, Apple had already come out with the thinner and lighter second-generation iPad. By comparison, the TouchPad feels bulky and heavy.

Entertainment gap the one big area where the TouchPad falls short of the iPad is in entertainment — music, movies and games. some of you will say “That doesn’t matter for a business device”. However, a lot of the professionals I know with iPads love to use them to watch movies during flights on business trips. the size of a tablet is perfect for a tray table or a lap, and it’s much nicer than wrestling with a notebook. the TouchPad simply doesn’t have the app or entertainment catalogue to compete with Apple’s iTunes or iOS ecosystem. However, if it could partner with Amazon, it could make up a lot of ground very quickly, at least on the entertainment side. Since Amazon has its Kindle app on the TouchPad at launch, at least there’s some potential there.

Bottom line for business For business professionals intent on productivity, there’s a lot to like about the HP TouchPad. the email and multitasking capabilities alone are enough to give it an edge over the iPad. and, we haven’t even talked about the TouchPad’s ability to print (especially to HP printers) — another important asset for some professionals. the expanded web browsing capabilities are huge, too. It allows the TouchPad to access a lot of sites (Flash and others) that aren’t accessible from the iPad. this can open the door to web-based business apps and other important sites.

I expect a lot of the consumer-oriented reviews to hit the HP TouchPad pretty hard because of its bulkiness, lack of games and entertainment content and paucity of third-party apps (although it’s ahead of Android Honeycomb and BlackBerry PlayBook when they launched). those are all valid concerns and because of them I certainly wouldn’t recommend the TouchPad for the average consumer.

However, for people who couldn’t care less about the latest games and movies and just want to get work done in meetings and on airplanes, the HP TouchPad will be a breath of fresh air. I consider it the most productive tablet yet and the first one that can serve as a legitimate notebook replacement for professionals on the road.

I think a lot of business professionals will find the TouchPad to be exactly what they were hoping for in a tablet because it will allow them to work the way they’re used to working, but do it in the convenient form factor of a multi-touch tablet. I would fully recommend the TouchPad to professionals if it weren’t for the performance issues and the fact that HP needs to add editing capability for Microsoft Word and Excel files (something HP says is coming ‘this summer’). with those two things in mind, I would recommend holding out until HP addresses those issues and adds more productivity apps to the catalog. I expect HP to keep pushing forward. Jeffery Ben, a Senior Product Manager on the TouchPad team, told me: “HP is committed to being on this journey for a long time”.

For professionals, the TouchPad is a solid first step.

Hello yeah i wanna upgrade my stock heatsink since i've overclocked my pc.

– I have a Biostar GF8100 M2+ motherboard and a AMD 64 x2 5000+ processor.
– will any kind of heatsink fit?
– can you recommend me a good relatively cheap one?
– will these artic cooling ones fit

Thanks David

Your stock cooler will do fine for your processor. just get some Arctic Silver thermal compound and put it on the heatsink (after you clean the gunk off) about the size if a grain of rice. It will keep the processor much cooler.

Have fun
