Iâ€™ve done some tests on the Kupa X11 and just like they say, itâ€™s possible to use it for up to 10 hours on battery. Itâ€™s impressive but what about getting things done on the Kupa X11? You can have all the battery life in the world but if you can’t use the device, itâ€™s worth nothing.
To test the real-world value of the Kupa X11 in terms of â€˜getting things doneâ€™ Iâ€™ve swapped out my Ultrabook-desktop for the Kupa X11 today and as you can see in the image, Iâ€™ve connected an external monitor, keyboard and mouse.
The Kupa X11 runs a single-core 1.5Ghz Intel Atom CPU. Itâ€™s about as slow as it gets from Intel but you have to remember weâ€™re talking about a CPU that can go in a phone here! Under Windows 7, the architecture required (USB, PCI, ACPI, display and more) means that you donâ€™t quote get smartphone-like battery life but itâ€™s quite impressive. You also get the advantages of being able to hit the ground running with a very flexible and productive operating system.
Average power usage as I type this, with Chrome (3 tabs), LiveWriter, Live Gallery and perfmon windows running, is 6.3W which is 6-7hrs of usage. Iâ€™m using â€˜high performance modeâ€™ but the CPU is still down-stepping to try and save power where it can. The Kupa X11 is silent.
This is not a desktop experience Iâ€™d like to have every day but Iâ€™m getting stuff done and Windows is providing me with all the facilities I need to get to work. Apart from a failed Bluetooth file transfer from a mobile phone, everything has worked smoothly. From plugging in the monitor to connecting a phone via USB to editing this article in the WordPress web interface.
The Kupa as a standalone tablet PC
Unplugging the monitor and working on the Kupa as a standalone PC is a slightly different experience. The 1366×768 resolution helps but font sizes need to be pushed up a bit and that reduces the advantage of the high resolution but here I am, with exactly the same applications running, an average power drain of 5.7W and a touchscreen in front of me that, given the right operating system (Iâ€™m talking about Windows 8) could be quite compelling, mobile and productive. Typing away with a few web apps running Iâ€™m seeing over 7hrs of battery life.
The question is, could this be better?
1.5Ghz Atom, even when coupled with 2GB of RAM and an SSD, isnâ€™t a fluid experience in Windows 7 and itâ€™s not going to be better in Windows 8 desktop.Â For my basic Web and typing requirements here it works well once all the apps are up and running but itâ€™s not going to be good enough for, say, a lengthy session of image editing, a 500MB unzip, or some heavy spreadsheet work. Is it going to be good enough for Windows 8 metro though? If it is, the Kupa can then be used in far more scenarios. I suggest it needs to lose 20% of its weight and tidy itself up a bit to become competitive in a mainstream market but as it stands, this 10â€ tablet is going to be a pretty flexible device for pro-mobile types and thatâ€™s exactly where Kupa are aiming this. With 3G and a fingerprint reader, it really does embody the requirements of a pro UMPC. Flexible, mobile, productive.
Now thatÂ I’veÂ done some testing with Windows 7, it’s time to load-up Windows 8. Stay tuned.
(The Kupa X11 has been silent through this hour of testing. Screen brightness was set to half.)
