Toshiba will launch a 12.5 inch detachable notebook/tablet with an Intel Core M Broadwell processor and up to 16 hours of battery life early next year.

We spotted a listing for the Toshiba Portégé Z20t at the FCC last month, and a few days later Toshiba officially unveiled the 2-in-1 computer, saying it’ll be available in the UK in the first quarter of 2015. There’s no word on a US launch, but I wouldn’t be surprised to see this portable notebook at the Consumer Electronics Show in January.


The Toshiba Portégé Z20t features a 12.5 inch, 1920 x 1080 pixel IPS display with a capacitive touchscreen and optional support for a Wacom digitizer.

The tablet features an Intel Core M processor with Intel HD 5300 graphics, up to 8GB of RAM, and up to 256GB of solid state storage. It has a micro HDMI port, micro USB port, microSD card slot, and headest jack and up to 8 hours of battery life.

Attach the laptop dock and you get a full keyboard and touchpad, a full-sized HDMI port, 2 USB 3.0 ports, VGA, Gigabit Ethernet, and an extra battery which allows you to get twice as much run time when using the Portégé Z20t as a laptop.

The system features a 5MP front-facing webcam, 802.11ac WiFi, Bluetooth 4.0, and optional mobile broadband.

The tablet section measures 0.35 inches thick and weighs 1.8 pounds. Attach the keyboard dock and you have a laptop that measures about 0.8 inches thick and weighs 3.5 pounds.

  1. Other than fanless, is there an advantage of any of these models over Haswell in terms of performance/wt/battery life. I just don’t see it- especially given the poor performance numbers we have seen due to low thermal overhead for throttling/capping of CPU and GPU.

    Intel has come a long way in terms of their CPU architecture, but I get the sense that the GPU heats up and forces everything to slow down. Especially now that ultra high res displays are becoming commonplace.

    1. Someone has the fanless Core M version of the Dell Venue 11 Pro here:
      He did some non-benchmark based gaming tests and it holds up well for prolonged gaming. Although, I don’t know much about PC gaming. I’m more interested in throttling from mostly CPU based loads.

      Other than the heavily throttled fan cooled Core M based Lenovo Yoga 3 Pro, what other Core M devices have you seen thermally throttle heavily? I’m interested if several OEMs are having issues creating fanless Core M devices and not just Lenovo.

      It makes me wonder how can Intel make a fanless Core M reference 10″ tablet and even configured for cTDP up at 6 W TDP without heavy throttling while OEMs can’t. Was the cooling system Intel designed just too expensive and complex to be practical? From the beginning of the ultrabook days it seemed Intel made great efforts in providing realistic reference designs though.

      1. I have only see reviews on a couple of models. The Yoga 3 was the worst, but I’m waiting to see a model that I lighter than haswell but has a full thermal overhead so you can have sustained higher CPU usage. I remember Intel using more expensive forged aluminum for their reference design. So companies can’t simply reuse their older designs. So increase in cost for both development and manufacturing.

  2. Nice to see the inclusion of a pointing stick. I just hope the keyboard doesn’t suck as badly as their current models. C’mon, Tosh, let’s have some decent key travel for a change!
