The Silicon: Bay Trail Inside

Obviously a big part of the Transformer Book T100 story is the inclusion of Intel's Bay Trail silicon. ASUS opted for Intel's second fastest solution: the Atom Z3740. That's four Silvermont cores running at 1.33GHz with a max turbo of 1.86GHz. I saw the T100 hit 1.86GHz fairly regularly, which backs up what we saw in our initial Bay Trail performance preview. For light tablet use, the Z3740 is incredibly quick. The beauty of Intel's latest Atom silicon is of course that it can run a huge library of x86 applications. I haven't spent enough time with Bay Trail to know whether or not its performance is truly good enough for most users. I suspect it probably needs to be a bit faster to truly replace a modern mainstream notebook + tablet, but if you're used to an older system you might be able to get away with Bay Trail. Intel claims ULV Penryn-like performance out of the fastest Bay Trail silicon, and I think that's a decent estimate. You benefit a lot from not having any silly mechanical hard drive inside, and unlike the initial wave of netbooks the T100 is actually usable.

I complained about multitasking performance in our recent Chromebook 11 review. Intel’s Bay Trail silicon in the T100 has no such  problem. Playing YouTube HD videos in the background while writing in Google Docs is a non-issue. I do occasionally see periods of high latency response, particularly when installing a new application. I believe this may be due to background AV scanning at launch.

It’s definitely possible to bring the T100 to its knees with just above a moderate multitasking workload. It’s important to keep in mind that we’re talking about ~1GHz Penryn sort of performance here and not what you’ll get out of a Haswell system. Think of it as better than what you’ll get from the ARM camp but still substantially behind what a more expensive Haswell solution will offer. Make no mistake, the T100 is very much an entry-level machine in terms of performance.

The four cores are paired with Intel's HD Graphics, a 4 EU implementation of the Intel GPU we saw in Ivy Bridge (running at up to 667MHz, sharing TDP with the CPU cores). The collection of CPUs and GPU are behind a 128-bit wide LPDDR3-1066 memory interface. Like most entry level notebooks in this price range the T100 comes with 2GB of memory. Internal storage is courtesy of an eMMC solution. I was sampled a 64GB model (using a SanDisk eMMC controller). Around 30GB of the device's storage was free at first boot (total partition size = 49GB, ~30GB free for additional apps/data).

ASUS equipped the Transformer Book T100 with dual-band (2.4/5GHz) 802.11n courtesy of Broadcom’s BCM4357. The T100 features a 1-stream (150Mbps) implementation. I didn’t have enough time to test wireless range/performance but the sheer inclusion of 5GHz WiFi in an entry level PC is music to my ears.

Software: Windows 8.1 + Office 2013

Although there are rumors of T100-like devices running Android, and eventually even dual-booting, the Transformer Book T100 launches with Windows 8.1. I haven't had much time to spend getting into 8.1 but it's largely an improvement over Windows 8. Overall it doesn't fundamentally change the concept behind the OS, although it does attempt to make migrating to it from other versions of Windows a bit easier. You have greater customization over the start screen's behavior, where the system boots by default (desktop or start screen) and installing applications doesn't automatically spam the start screen with tiles. You also get truly universal search now integrated into the start screen, which is a life saver.

Since you're dealing with an x86 version of Windows 8.1 here, you can obviously run nearly all old x86/Windows applications. This is a huge deal as it means you can replace IE11 with Chrome, not to mention use the T100 just like any other PC. I'm honestly surprised by the lack of really good 3rd party Windows applications that use the new UI. I expected there to be more uptake by now, but I was very wrong. The T100's success doesn't depend on having more modern UI Windows 8.1 apps since it can still function like a traditional PC, but the undocked tablet experience could surely benefit. Windows 8.1's native apps are definitely better this time around, but the tablet experience alone isn't as good as what you'd get on Android or iOS. Microsoft's new UI definitely has its moments (I'm still a fan of how easy it is to multitask in the OS), but it still has a long way to go.

Intel's silicon in the T100 is 64-bit capable but Microsoft still lacks a 64-bit version of Windows 8/8.1 with Connected Standby enabled. As a result, the T100 (just like all other Bay Trail platforms) ships with a 32-bit copy of Windows 8.1 (with Connected Standby enabled).  

Another huge component of the T100 offering is the in-box Office 2013 Home & Student Edition serial key. Office 2013 is pre-loaded on the device, and each box should have a booklet with a serial key to unlock the Home & Student version of the suite. I realize there's this march away from Office, but to those who still heavily use and depend on the suite it's a tremendous part of the overall T100 value.

    The pricing of the Asus T100 with 10" display in a toylike "plasticky" case priced around $400 for only 2GB of memory and no SATA drive capability shows how limited options OEMs have with Baytrail Atoms. It loses especially badly in graphics to a quad core Kabini.

    By comparison, the Toshiba Satellite 15.6 Touchscreen C55DT-A5307 sells for $399.99 and comes with quad core A6-5200 Kabini, 4GB memory and 500GB drive. Users can upgrade to more memory and SSD drives. By any comparison, it is a much better value and provides overall great PC user experience versus limited Asus T100 for the same price.

    you are comparing two completely different machines. Reply
  • Hubb1e - Friday, October 18, 2013 - link

    A 15.6" laptop meets a completely different use case than a 10" tablet hybrid. The Tablet is a portable consumption machine that can do some work in a pinch. A 15.6" laptop is a work / play machine that can be portable. I don't see shoppers really cross shopping the two. I see people with both. Reply

    Plus, with stuff like a TN display (of the same resolution but 5" larger, no less!) and a mechanical hard drive, the user experience most likely suffers. You're trading size for cheapness. Reply

    Can you tell us how the factory restore works? Is there a proprietory backup software? Or does it use Windows Refresh? How do you refresh it if you cannot boot into Windows? Is there a special key combination that would cause it to enter the recovery mode when pressed? Can you completely remove the recovery partition from the drives and make a USB recovery drive in case you are going for the 32GB model? Reply

    This might be of interest to you. You'll be paying far more than $10 extra though.

    Waiting a look in Bay Trail M + SATA,

    in Windows x86 OS I dislike the eMMC storage system, it is an execrable design, the heavyweight Windows x86 OS is fully unlike in the lightweight Android OS, Windows needs SATA and PCIe, but Atom Bay Trail T is still no support SATA and PCIe.

    Intel actually wanted in Android to compete with ARM processor, does not really want Bay Trail T to help Windows tablet to compete market, because the x86 processor is almost no another competitor! Now is Intel wanted to control the Android market!

    Would've been great to up the price by $15 for that, or $25 for that and RAM. Then good margins still, but good benefit for consumers. Reply

    The Z3770 is probably similar in battery life/size/cost/weight. I'm guessing price points was the key. It would have been nice to offer the 64GB version with the upgraded CPU. Reply

    It may be the case that Intel could not supply the Z3770 in sufficient volumes. This is often true for the top-range part number early in a design's life cycle. Reply
