Final Words

This is a tricky conclusion to write, because as always there’s a lot of concluding that has to be done. On the one hand, we have Intel’s Clover Trail platform. On the other we have Acer’s Iconia W510 tablet itself. And on a magical third hand we have to conclude on behalf of Microsoft’s Windows 8.

I’ll start with the Intel hand.

Clover Trail is good. I only have NVIDIA’s Tegra 3 to compare it to at this point, and there Intel wins hands down. Performance is clearly better, tasks complete quicker, the modern UI is even more responsive. Power efficiency, once again, seems like a non-issue. The W510 in particular uses a smaller battery than most, but its battery life per watt-hour is very similar to Surface RT. Samsung’s ATIV Smart PC actually seems to be a better showcase of what Clover Trail can do from a power efficiency standpoint. If we haven’t squashed the notion of Intel being unable to build low power SoCs by now, Clover Trail should help drive the nail into that coffin. The debate is no longer about whether or not Intel can build something competitive with ARM on the power front, but whether Intel can execute quickly enough to defend its marketshare.

Backwards compatibility is a hit or miss advantage for Clover Trail. If you use it for the flexibility of being able to run nearly every Windows application available, then you’ll be pleased. Small apps that I’ve relied on for years just run without issue on Clover Trail. I don’t need to find modern replacements, my library of tools just work. I suspect this advantage will appeal in enterprise markets where custom applications are often on very long development cycles.

However if you’re expecting to be able to enjoy a similar experience to what you currently have on your Ultrabook, you’ll be sorely disappointed. Atom isn’t Core, the performance delta is dramatic. The Windows 8 desktop experience on Clover Trail is like using a notebook from several years ago. Performance is at least consistent thanks to the lack of any mechanical storage, but running intense workloads on the platform is hardly quick. Being quicker than most of the ARM platforms on the market today isn’t enough, Intel has to deliver a good experience across all applications. The experience is further hampered by sub-par UI performance in desktop mode. It actually feels like Tegra 3/Surface RT are faster when it comes to desktop UI performance. This highlights a disturbing trend within Intel’s ultra mobile products. The company continues to under-spec its ultra mobile GPUs. If Intel is really serious about both the tablet and smartphone markets it needs to build the best SoCs in the world, and that means delivering the best CPU and GPU performance.

I was impressed by the unique combination of closed box tablet OS and flexible/customizable desktop OS that Windows RT delivered. Windows 8 on Clover Trail takes that feeling to a completely new level. Being able to install and run nearly any weird, old application in one breath and then switch over to a fairly well optimized tablet experience in the next is pretty awesome. Where the experience falls short is really the performance of desktop mode and most of the applications I’d like to run unfortunately. Scrolling isn’t smooth, response time is pretty bad if you’re running anything demanding. You have to keep in mind that, at best, we’re talking about mainstream notebook CPU performance from around 2005. Until Intel revs Atom (which should happen next year, thankfully enough), the backwards compatibility story won’t be as awesome as it could be.

On the Acer side of things, the dock experience (particularly the troubles I had with the clickpad) also contributes to the W510 not being the perfect tablet+notebook in one. As a standalone tablet I prefer the W510, it’s got a great form factor and I love its light weight. As a docked system however, Samsung’s ATIV Smart PC seems to be the better choice.

The W510 itself is well executed, but overall the experience seemed a bit less polished than with Microsoft’s Surface RT. This is where things get really complicated. I want the SoC from the W510 but in the overall device experience that Microsoft’s Surface delivered. I even think Acer might have a form factor advantage in the W510 since it’s just so light. It’s a shame that the only x86 Surface device will be the bigger Pro model.

Ultimately my conclusion about the W510 in particular is a lot like what I felt about Surface RT. You know it’s going to be made obsolete in less than a year’s time, so you have to be ok with that fact if you’re going to pull the trigger today. Even then, the experience isn’t perfect. Microsoft still needs some updating on the Windows side to address bugs and quirks with the OS. Performance isn’t as big of a problem on the W510 as it was on Surface RT, but I’d still like to see more on that front as well.

Much of the same goes for Windows 8. Although its execution hasn’t been perfect, I really do like the OS and I see a lot of potential in these converged notebook/tablet devices. Especially for users who travel a lot, being able to have the best of both worlds in an extremely portable device is a wonderful dream. I think Microsoft has the right vision, but what we need to see are more revs to the OS to fully realize it. The real question is whether or not Microsoft will be able to deliver significant updates to Windows 8 as quickly as the market needs it.

    are the windows x86 drivers for powervr sgx now stable and feature complete? the first batch of reviews for atoms containing these, including the one in anand iirc, complained a lot about the stability of video drivers.

    the fact that these crashes are system-wide, would rule out specific applications, but not drivers.

    windows 8 by itself, especially on x86 (but maybe even more so for the rt on arm) has been very stable.

    Can we get a detailed write up of how eMMC differs from SATA?
    I'd be very interested in reading Anandtechs analysis on the differences between them.

    It just seems to be the very prevalent now with smartphones and Atom tablets both using it.

    MMC is a memory card standard similar to the more common SD; eMMC is just an embedded version. Outside of the embedded world MMC is mostly used to increase the number of supported formats claimed by card readers. Reply

    I am very curious about the Z2760 electricity consumption when running kraken.

    Great! Hope you use a test application which could utilities all of the CPU cores. Kraken is good but not perfect, could Kraken make 100% usage on dual core? Reply

    Could you add dimensions for the combined tablet + dock? Reply

    Clover Trail is a failure. It is competitive with Tegra3. Great.

    But tegra3 itself is outdated now. Anyone notice that no new top-line smartphone has tegra3. All have Krait4. And will soon have Exynos5.

    If all Intel has to show for its efforts is competition with tegra3/A9 , its in some deep shit.
    The GPU is particulerly shitty. Either Intel need a node shift to 14nm, or a new arch or both.

    Maybe I'm being naive, but it sounds like Bay Trail will be exactly that new architecture for Atom that Intel needs. Reply

    Clover Trail is just a stop gap. It's using a 5 year old architecture with a GPU that even the iPad 2 from 2 years ago could outperform. I think it's purposefully designed to be cheap.

    I'd be far more interested to see what Bay Trail (next-generation Atom) and Haswell (next-generation Core) bring to the table, because at least it will look like Intel is trying.
