System Performance

The Toshiba KIRAbook may be using the current "entry level" low voltage Intel Core i7, but it's still an extremely fast processor. The Ivy Bridge-based i7-3537U features a nominal 2GHz clock speed and is able to turbo up to 2.9GHz on both cores or even 3.1GHz on a single core, power and thermals depending. The HD 4000 graphics are also able to jump to 1.2GHz, but that advantage is likely to be much more modest. Finally, the SSD in the KIRAbook is a very capable one and should help it out in PCMark.

PCMark 7's leanings towards SSDs are essentially correct; as a whole, the i7-3537U in the KIRAbook is faster than any of the other ultrabooks tested, and the SSD is definitely snappy. It's remarkable that the vastly more powerful CyberPower Fangbook (which includes a 256GB Samsung 840 Pro) doesn't bludgeon the KIRAbook harder.

CPU-centric benchmarks are also mostly in the KIRAbook's favor, but the first pass in x264 isn't as strong as it ought to be. The entry KIRAbook will be equipped with the same CPU as the Dell XPS 13 in these charts, so you're looking at a measurable decrease in CPU performance going that route. If the extra $400 for the upgrade to our review unit meant more than just Windows 8 Pro, a touchscreen, and the i7-3537U it might be easier to justify, but the i5-3337U is still a totally serviceable CPU.

3DMark performance of the KIRAbook is pretty much par for the course; any differences between the ultrabooks listed can probably be chalked up to thermal design differences between individual chassis rather than differences in the CPUs themselves.

    Is it just me or... does it look exactly like my Asus Zenbook? Lol.
  • sweenish - Thursday, May 9, 2013 - link

    It looks a lot uglier than a Zenbook, to me. The colors and shape are just so plain. Nothing pops. But I may have a bias as I think that the Zenbooks and Series 9s are the best looking laptops on the market.

    What about display scaling though? That resolution would make elements tiny without setting Windows scaling, and Windows scaling breaks some things (usually old or poorly coded, but still) since it's not perfect integer scaling like the rMBP at default. I'd be interested in some commentary on that.

    I'm not sure if it's really fair to compare 13" retina MacBook Pro to the Kirabook, considering that the rMBP is 20% heavier. In fact, the Kirabook's weight (1.35kg) is identical to 13" MacBook Air.

    Well, going by the specs though, that 20% is just 270g. And the MBPR is only 6% larger. In exchange for that very small sacrifice in portability, you get a 42% larger battery (74 Wh vs 52 Wh), a 2.6 GHz Core i5-3230M or 3.0 GHz Core i7-3540M as opposed to a 2.0 GHz Core i7-3537U, up to 768 GB SSD options, and a 2560x1600 display. I guess my point being the price for thin and light is getting a little ridiculous when you compare either the high-end MacBook Airs or the KIRAbook to the 13-inch MBPR.

    Kudos on the DS9 reference.

    Have to agree about the lack of screen discussion. You basically just reviewed a revolutionary (for Windows) 1440p 13" laptop and did not say a single thing about how the display works or looks with Windows 8. Can you scale this to 1280x720 and get sharp graphics for gaming, like you can with the rMBP?

    Got to say,
    I'm really liking the little pithy commenty thing in the top right of the article headers.
    And dead-set right, Dustin, on the point about why doesn't anyone do a gunmetal/"titanium-colour" or bronze-coloured metal chassis.

    Ain't monopolies grand? :D

    If you think Amber`s story is impossible..., five weaks-ago my cousins friend who's a single mom basically also made $4658 workin a fifteen hour week from their apartment and the're classmate's mother-in-law`s neighbour was doing this for seven months and actually earnt over $4658 part time on there labtop. use the information available on this page Jump44.comTAKE A LOOK
