Fastest 4.5 Watt Core M 5Y71 In Asus T300 Chi Competitive With Full Core i5 CPUs 48

MojoKid writes: Asus unveiled its latest addition to the Transformer series at CES in January, the Transformer Book Chi, which just recently began shipping. Available in three sizes, the new Transformer Book Chi Series features a 2-in-1 detachable design. The flagship Transformer Book T300 Chi offers a 12.5-inch screen, an Intel Core M processor, and a fanless cooling solution. The 2-in-1 detachable design employs a magnetic hinge that supports four usage modes: Attached, Detached, Flipped, and Tented. The T300 Chi measures about 0.65 inches when docked, making it slightly thinner than an Apple Macbook Air. Asus claims the T300 Chi is the world's thinnest Windows tablet, measuring just 0.28 inches thick. More interestingly, perhaps, is that Asus built this machine with Intel's fastest Core M chip, the Core M 5Y71. In the benchmarks, it competes well even with full-sized ultrabooks, though battery life does take a hit due to the system's mechanical limitations and smaller 31Whr battery. At prices from $400 to $900, this might be an interesting choice for anyone considering the new Surface 3, too.

      Charging more for less, the Intel way!

    • I'm still not over their "Pentium N" or as I like to call it, an atom CPU with a 1000-ish passmark rating. 50% slower than the 3rd edition Pentiums. Veeeeery impressive, Intel.

        It's impressive if you take the TDP into account.

      The i5 and i7 designations don't indicate performance but feature sets. Current i5 processors don't have hyper-threading, for example, but all current i7 processors do. The low end Pentiums didn't have virtualization support (but current Pentium-N do). All in all though, Intel branding and marketing with regard to their core product is a clusterfuck. Not even people who care about these things can readily tell which is the better CPU anymore.

      It's a tablet. They're cramming the computer into the screen. So it needs to run cool.

      Contrast that with a traditional laptop whose internal organs rest underneath the keyboard. It blows out excess heat out each side using a fan.

      If you want a noisy, fast, Core i7 laptop, don't get a convertible.

      • I picked up an Asus Q551LN [bestbuy.com] recently and despite it being a "convertible" laptop (which I will never "convert" but the only other i7-4xxx 15" options were a junky plastic HP and a "Republic of Gamers" cinder block) it has a proper cooling system in the hinge area similar to an older MacBook Pro (though not nearly as poor). It's a Core i7 ULV; it's not noisy but it's pretty darn fast. Admittedly, it's half the PassMark score of a 4710MQ, but the low TDP (it barely gets warm) and the fact that I don't have to

      I totally agree, Intel has pretty much dumbed down the Core processors in order to cut power. Anyone who buys a ultrabook can expect a ultra low powered core i3 or i5. Yes, clock speed fools you into thinking its still a good CPU. But let me tell you, my new Macbook Air 2014 is slower just from using it then my 2010 Macbook Air. Sure, I mange better battery life for sure, but not without compromising performance a bit. Right now, the push seems to be toward saving energy and not worried so much about cloc

      Well, it's Intel branching out.

      You want a fast laptop? They still exist - big, heavy, poor battery life, but plenty powerful and ready for the heaviest of gaming sessions or CAD or compiling or whatever.

      But Intel's realized most PCs are "fast enough" so why not make a lower power chip so you can make cute, svelte, thin and light PCs that

    • People buy way, way, way more phones and tablets than workstations. Intel will go where the market wants to go...

    • No, not really. You are currently able to get more powerful laptops than ever before. Sure, the high-end of the range gets no coverage because the mall retailers don't sell them, and Intel are now focusing their 14nm capacity on where it's most needed, on low-end laptops, tablet, phones and so on. But if you, like me, need more power (actual quad core, high clock speeds, etc) they have plenty to choose from such as these Core i7s [intel.com]. Personally I use an i7-4712HQ, and it does everything I need with great spee
  • After the incredible piece of shit that my TF700T was, never will I buy an Asus tablet again.

    Nice screen (it was one of the first android tablets to have a really high-res screen), the graphics processor and CPU are fast...but they completely screwed the pooch on the flash architecture, making the thing crippled; any sort of disk IO causes it to slow to a crawl. There are all sorts of hacks to make just web browsing bearable, by using a ram disk to completely avoid the flash. People also put in the fastest

    • Yes. I agree completely. Fuck Asus. I bought the Transformer Prime from them, with the shitty ass wifi and GPS reception. The only thing they would do for it was give us some crappy ass GPS dongle to attach to the damn thing. Thankfully Amazon stepped up and honored people's requests for a refund due to it being essentially defective and the manufacturer refusing to help.

      So I bought the Transformer Inifinity (two actually...one for me, one for my wife). The thing was pretty nice at first, but with every sin

        My Mom purchased a laptop Aspire_V5-571-6499 (Windows OS) it won't work for her, after the refund date she tried to, she was stuck with it so gave it to me. Trying to make the battery to last longer some things weren't give the power they needed, one being the WiFi, even changing the power settings the WiFi is worthless, it worked on 1 of 3 routers I have and not reliably. My son now has it and not really all that computer literate so he'll never know (it has a land line).

        • I have a current Asus Transformer running Windows 8.1 and it's been a great tablet. If I tried to pretend it was a laptop I would probably be disappointed. But at the time I was trying to decide between buying a new 10" Android laptop and this thing, which runs real x86 Windows software. For the same price point I opted for the x86 tablet and I haven't looked back. I have an Asus 10" Android tablet that is about two years old and I haven't turned it on in weeks.

          The Windows tablet stuff only needs enough

    • That's why you need an SSD, not just embedded "flash". Perhaps eMMC 5.1 flash will be good enough.
      Also why a machine with a hard drive is not that bad : it writes only slightly slower than it reads, and can write a single sector. A great SSD can be 100 times better than a HDD, but the worst HDD doesn't crumble down like slow, ill managed flash does.

    According to Passmark, this chip is clocked at 1.2GHz with a "Turbo" speed of 2.9GHz. In other words, it can do very short bursts at nearly 2.5x the clock speed, then have to scale back down to normal because of the heat it would generate. So while this thing looks awesome in synthetic benchmarks, how would it seriously handle in a sustained computing environment?

    • by Anonymous Coward

      It's not meant for that. Short bursts of computing power are useful for many tasks such as rendering a webpage, converting an image and so, reducing latency and making the system feel snappier.

      Benchmarks are a more 'sustained' CPU load than typical home/office use. If anything, I think these would feel faster than the tests imply. Not everyone spends their day compiling code or applying Photoshop filters. (What's wrong with them?)

    • What tablet is used in a sustained computing environment? This about portability and battery life, not rendering models or transcoding video.

    It may be competitive with an i5 (whatever that means) but only short bursty workloads because if it's anything like the other Core M processors out in the wild, it will start heavily throttling after a couple of minutes.

    I bought an after market lithium battery and now my laptop lasts for days, weeks, even months between charges. The extra weight is a tradeoff. When people see it, they ask "What the hell is that!" But that's normal when you are cutting edge.
