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.

    They both include the dock. I wish they would sell a cheaper version without the keyboard, at least as an option. Reply

    that's the thing and I know I'm like 3 years ahead of this article, the asus t100 is not a TABLET. its a 2in1 hybrid. its a compact laptop with a removable touch screen. the other devices are just bs tablets Reply

    Battery Life seems acceptable, at least it stayed more or less the same as Clover Trail and being quicker at the same time.

    However, 2GB RAM is quite concerning here, I personally use a ThinkPad Tablet 2 at school,
    which can use 1.8GB RAM with just OneNote & IE & some PDF documents.
    Using Bay Trail as 32-bit SoC with 2GB RAM & Windows is not a good idea IMO,
    it is not that sufficient by today standard.

    then buy something with 4GB of RAM or that can be upgraded. This is a 350.00 tablet. Reply

    I agree, 2GB for Windows hardware is substandard. My 3 years old netbook supports 2GB. Reply

    3 years later I'm still using an asus t100 now with windows 10 64 bit.... has ran and continues to 3 years after this article . ive trashed atleast 6 tablets Reply

    Out of curiosity, does the Intel Power Gadget - http://software.intel.com/en-us/articles/intel-pow... - work with Baytrail? Would be quite interesting to see what it reports for package power under the various workloads if it does. Reply

    This is a good example why Intel's approach of really low-end devices succeeds and why Microsoft's Windows RT attempts fail. Intel gets ~30 USD, Microsoft still gets a fair share of licensing money but the user gets a full 2013 Home edition suite including damn macro/vba-support that RT doesn't provide. It supports connected standby (Surface 2 don't), but I would wait till these devices run 64-bit Windows. It does show that when they run the exact same platform and Metro is basically just the start screen that is still powered by Win32 underneath it does make RT entirely pointless. It has still better battery life than first gen RT-devices. Dock is obviously an necessity for all the Win32 apps this thing is suppose to run Reply

    " It supports connected standby (Surface 2 don't)"

    Surface Pro 2 doesn't. Surface 2 (and the Surface RT, for that matter) will of course support Connected Standby.

    As for macro and VBA support, it might be useful to you, but how common is that stuff in general? Seems pretty rare these days to me.

    Could do without the sensationalist title. Reply
