    Is PCMark 8 Home less demanding than 1080p video? If not, it doesn't seem like the Asus can call itself an Ultrabook.

    Still, impressive gains in battery life. I hope this will carry over, to some extent at least, into the CPUs that will be in laptops like the MacBook Pros. Guess we will have to see when that review comes out =)

    As far as I know the Ultrabook specs don't define a minimum luminance for the display. So Anand's test isn't relevant for the Ultrabook spec. Reply

    Laptopmag just reviewed the Sony Vaio based on the i7-4500u and they also noted that performance wise the Haswell offered marginal improvement over Ivy Bridge laptops, while battery life was indicated as improved.

    One important characteristic that most laptop users want to know is regards to heat and fan noise. Laptopmag found that the Haswell i7-4500u based Sony Vaio found that the back of the laptop "reached a more troubling 110 degrees." They also found fan noise was definitely noticeable in a quiet room just running Word and a Youtube video.

    The question is, why hasn't Anandtech run extensive temperature and noise characteristic analysis on Intel Haswell processors and your current laptop?
  • Kristian Vättö - Sunday, June 09, 2013 - link

    Likely because of lack of time. As Anand said in the article, he got the unit while in Computex, so basically he did the review between meetings. I'm pretty sure he didn't have the equipment with him to do temperature or noise tests properly but I'm sure this is something that will be tested in later reviews.

    Also, keep in mind that heat and fan noise are system-dependent. If the Vaio has poor cooling, then it will be hot and loud but that's not Haswell's fault (I'm not saying this is the case but we obviously need more reviews before any conclusions can be drawn).

    "The question is, why hasn't Anandtech run extensive temperature and noise characteristic analysis on Intel Haswell processors and your current laptop?"

    The WHr of battery that a laptop consumes is the exact same thing as its heat output.

    Anand is trying to test the Haswell platform, not the design deficiencies of any specific manufacturer. Sony's problems are its own.
  • n13L5 - Sunday, June 09, 2013 - link

    Cause they had to run their test in Taiwan with a borrowed machine?

    I was rather disturbed by the temperature of Sony's Vaio Pro, as well as the instability of the carbon case, which must be paper thin... And their keyboard backlight has the worst bleed I've ever seen, they should have a look at Lenovo and Samsung keyboards...

    Well, I'll be waiting for more tests and the ULT Haswell with the Iris 5100 GPU. Maybe that'll rack up a high enough temperature to fry a steak.
  • akbisw - Monday, June 10, 2013 - link

    The fact that companies historically known for horrible battery life are getting good results out of Haswell with Intel's help is promising; but starting from such a horribly low baseline makes getting gains much easier. I'm much more interested in seeing what companies who've historically offered good battery run times will be able to do with Haswell. Reply

    I just don't get why Intel caved to MS pressure and made touchscreen a requirement for Haswell. Everyone I know who does image editing insists on doing it on a matte screen.

    Metro was a huge mistake.

    Gaah, just too pissed about this to make a coherent comment.

    I want haswell with a matte screen and 13 and 15 inch 'ultrabook' size options. I guess manufacturers will just have to invent some new name to call their matte screen ultrabooks. Perhaps just call them 'laptops' and say screw you and your goof ass naming rules Intel.

    not really, intel currently uses an abnormal 180mm2 of die area on 22nm (hd5000) for the same perfomance and efficiency of an 80mm2 28nm amd gpu.
    the are trying to go all out, but their gpu tech basically sucks
  • smartypnt4 - Monday, June 10, 2013 - link

    Where'd you see the analysis of how much space HD5000 takes? I haven't seen anything on that. Maybe I just missed it...

    180mm2 of die area for Haswell ULT total is what's been reported, and AMD's Trinity 4C at 28nm is 246mm2. The number of transistors in each is basically identical. The difference comes in where Intel and AMD spend transistors. I'd wager that AMD spends more transistors in GPU, and Intel spends more in CPU.

    To be frank, I don't see how you can assert that Intel's <90mm2 of graphics on an integrated chip has appreciably lower efficiency than any other mobile part on the market. I could be wrong, but I just don't see it as that far off.
  • smartypnt4 - Monday, June 10, 2013 - link

    Never mind. Found Anand's analysis. There's no way that's correct though. If 1/2 of GT3 takes up 87mm2, then full GT3 takes up 174mm2. Haswell 2C ULT is a 184mm2 die. There's no way the GPU takes up 90% of the chip. Over half, sure. but 90% is ridiculously high. Something in the 75-80% range is the absolute highest I'd expect. Reply
  • Homeles - Sunday, June 09, 2013 - link

    A bit disappointed to see the CPU performance largely stand pat compared to Ivy bridge, but it nailed the one major thing that mattered: battery life.

    GPU performance isn't awfully inspiring either. I suppose that I won't see the performance gains I was hoping for until Broadwell.

    Oh well. I suppose Fall IDF isn't too far away.
  • meacupla - Sunday, June 09, 2013 - link

    Well, i7-4500U is clocked 100mhz slower, but haswell IPC is about 10% better, so obviously CPU performance is not going to differ by much.

    GPU performance for HD5000 is pretty much what was expected from early intel slides. Iris pro is what was touted as performing up to 'more than 2x' performance.

    I am not comfortable with your suggestion that DEVSLP's 2 mw benefit shows exclusively/primarily when the system is asleep. I sense a big benefit at low loads because the SSD's can slip in and out of DEVSLP really fact. Let's have some testing, at your leisure. Will a SSD be in DEVSLP state 50% of the time while watching non HD video? I suspect power requirements during DEVSLP is the new idle power measurement for typical home use and SSD reviews should be revised accordingly.

    "The shift of consumer dollars to smartphones and tablets instead of notebooks and desktops won’t be reversed, but a good launch here might at least help keep things moving ok until Silvermont, BayTrail and Merrifield can show up and fill the gaps in Intel’s product stack."

    I love you Anand, and I love your tech analysis. But it might be worth your team acquiring a business analyst, or at least asking those sorts of questions of your informants.

    Silvermont does not "fill the hole in Intel's product stack" because that hole is business-based not tech-based. We saw the prices of Haswell a few days ago --- $250 and way up. Meanwhile the price of a high-end ARM SoC is, what, $20? That's one hell of a difference.

    The problem intel faces is that, for many purposes, it's perfectly adequate to pay for the $20 ARM CPU rather than the $250 Intel CPU. Silvermont and the whole Atom strategy, rather than making things better make things worse. Yes, now maybe Intel captures $20 from sale of an Atom --- but that Atom is ALSO able to replace Haswell (or at least lower-end but still more expensive Intel CPUs). The SMART Intel strategy would have been to acquire an ARM ISA license, making competitive ARM CPUs at $20 (so you still capture from that market) but at least avoid competing so directly with your more expensive line.

    Intel's problems from here on out are business problems. They have to compete with an architecture that is simple enough that Apple could put together a competitive CPU starting from scratch in two years, and they have to do so using an architecture that is so complicated it took Intel 5 years to out together a competitive CPU. Meanwhile they can't charge Haswell prices to maintain the massive parallel design teams that are required to create these ever more sophisticated x86 designs.
    (And, to make life even worse, apart from the myriad own goals Intel has inflicted, they have MS in the background insisting on its charges for Windows x86, one more drag on the sale x86 in the tablet market.)
    I don't think things are nearly as rosy for Intel as do you. Technically yes, they are well-positioned right now. But they seem to be in the position of DEC or IBM in the early 80s --- technically superb, but with an extremely problematic business model. And it's business model that determines the future, more than technology...
  • rwei - Sunday, June 09, 2013 - link

    IIRC Intel does have a full ARM license. But supporting ARM by making ARM parts competitive with Intel's x86 ones would be a blow to their future ability to extract economic rent for x86, as more software targeted at ARM became available.

    Much preferable to decisively beat ARM for 1-2 generations with x86 parts - if they can manage it.
  • peterfares - Monday, June 10, 2013 - link

    ARM is going to keep getting better and better with or without Intel. It might be smart for them to have the best ARM chips because then they'd get the money from people buying ARM chips. Not too much better than the rest that it impacts their x86 chips though. Either way, I'm glad that we can get affordable x86 computers. Until Android can truly compete with Windows on the bigger screens I'll stick with x86 Windows. Android is a LONG ways away from being able to replace Windows for me. Intel is in a tough position though. Reply
  • meacupla - Monday, June 10, 2013 - link

    The main short comings with ARM are the lack of processing power and the massive power consumption increase with faster chips. These chips are good enough for a majority of users and the OS' that run on them support just enough games and programs to keep those users happy.

    Intel, on the other hand, have chips that are fast, but need to get their power consumption and heat output lower. There's no shortage of games and programs that only run on x86, so if you need to run a specific program that won't work on ARM, your choices become quite limited.
  • Amagus - Sunday, June 09, 2013 - link

    Is the increased battery size without increasing size/weight of the system a result of a better battery/design by Acer, or is it directly influenced by Haswell (eg lighter/smaller platform)?

    "the processor graphics story by finally delivering discrete GPU class gaming performance". I hate this summation being thrown around, as I'm sure it will get re quoted somewhere as gospel. It is definitely NOT discrete GPU class gaming performance in any shape or form. There should be a limit to what is considered discrete GPU performance, like maybe 30-60FPS at, at least 1600x900 resolution and game settings across the board for all games set to Medium. That is not crazy or unreasonable for a true discrete GPU you would actually go out and buy. It shouldn't be unreasonable than to expect that in a built in GPU that is sold as "discrete GPU" quality.
