The Test

To keep the charts clean and simple I omitted a lot of the config details of each of the notebooks. For your reference, here's the configuration of each of the notebooks in our tests:

 

Alienware M11x (SU7300 + GT335M + HDD + 63Wh)
Alienware M11x R2 ( i7-640UM + GT335M + HDD + 63Wh)
Alienware M11x R3 (i7-2617M + GT540M + HDD + 63Wh)
AMD Llano (A8-3500M + HD6620G + SSD + 58Wh)
AMD Trinity (A10-4600M + HD7660G + SSD + 56Wh) 
ASUS N56VM (i7-3720QM + HDD + 56Wh)
ASUS U30Jc (i3-350M + G310M + SSD + 84Wh)
ASUS Zenbook Prime UX21A (ULV IVB + HD4000 + SSD + 35Wh)
ASUS Zenbook UX21E-DH71 (i5-2677M + HD3000 + SSD)
ASUS Zenbook UX31E (i7-2677M + HD3000 + SSD + 48Wh)
Dell XPS 13 (i7-2637M + HD3000 + SSD + 47Wh)
Dell XPS 14z (i5-2430M + HD3000 + HDD + 58Wh)
HP Folio 13 (i5-2467M + HD 3000 + SSD + 60Wh)
Dell Inspiron 11z (SU4100 + GMA4500 + HDD + 56Wh)
Dell Adamo 13 (SU9400 + GMA4500 + SSD + 40Wh)

 

 

Performance

As I mentioned earlier in this review/preview, the deal ASUS worked out with Intel prevents us for discussing clock speeds or specifications of the ULV Ivy Bridge silicon in the Zenbook Prime. Obviously the silicon is going to fit within the same 17W TDP as its predecessor so don't expect huge differences in clock speeds.

PCMark 7 - PCMarks

If you take into account Quick Sync and its SSD, the Zenbook Prime is an extremely quick solution. Looking at the breakdown of PCMark scores you get a much more realistic look at where the ULV IVB fits into things.

PCMark 7 - Lightweight

In some areas the Sandisk U100 holds the Zenbook prime back, here it's actually slower than its predecessor. Despite all of its issues throughout most of last year, SandForce was always fast.

PCMark 7 - Productivity

PCMark 7 - Entertainment

PCMark 7 - Creativity

PCMark 7 - Computation

PCMark 7 - Storage

I threw in a PCMark Vantage graph as we have a lot of older data in that benchmark that can help put things in perspective:

Futuremark PCMark Vantage

It's amazing the sort of performance gains we're able to show over the older Core 2 based ultra portables like the Dell Inspiron 11z and Adamo 13. Again we see a slight performance deficit versus the SandForce based UX21E.

    Possibly, though it's NVIDIA hardware and I think GT 620M is just recycled GT 525M or something (Fermi GF108), so it can't do all three. However, it might be able to do internal on the IGP and two external on discrete? Somehow I doubt it, though; the only laptops I've ever seen running more than two simultaneous panels are using AMD GPUs. Reply

    not sure how you count your panels but I have 2 external displays plus the laptop display running on an old X301
    using a usb to dvi connector for the second external display - you couldnt use it for anything too serious but for general office apps its fine

    Dell XPS 13 with Ivy Bridge? HP Elitebooks (Elitebook Folio?) with Ivy Bridge? Report back sometime :)

    We won't find out until later in June I guess.

    Actually there is a way to have what 1ceTr0n wants and keep the ultrasleek design:
    - fully implemented (micro-)HDMI - that includes CEC and Ethernet, which are optional in the HDMI spec (for CEC you need to add a very small chip - until Intel/AMD/Nvidia start implementing CEC in the GPUs; for Ethernet you need your standard laptop Ethernet controller - Intel, Broadcom or whatever; then you need only a cheep passive cable to use Ethernet)

    If I were in ASUS place I would have done also the following about ports:
    - fully implemented mini-DisplayPort (instead of the mini-VGA) - that includes CEC and USB2.0 (for CEC you need to add a very small chip - until Intel/AMD/Nvidia start implementing CEC in the GPUs; for USB - just redirect wires from the chipset; USB in Displayport comes in handy for single cable to monitors with integrated USB hubs/cameras, also it can be converted to one additional standard USB port by the use of cheap passive cable - for devices tolerating 3.3V or having their own power supply - such as hubs) - and Thunderbolt as option for 13" premium models
    - USB3.0/eSATAp600 combo ports (for the forum skeptics - http://www.delock.de/produkte/F_246_intern_61862/m... is an example of such port) supporting USB Battery Charging 1.2 (7.5W over standard cable) and draft USB Power Delivery (100W over new type of cable) - and remove the power input port (the laptop will be charged by one of the USB PD ports - just like phones are charged by micro-USB currently) - more space for SD card reader or other ports/LEDs/wireless switches

    Wireless interfaces I would've added:
    - Bluetooth 4.0+HS (over WiFi PHY)+LE (over WiBree PHY)
    - NFC
    - FM radio with RDS and internal antenna - receiver and transmitter
    Options for premium models:
    - GPS/GLONASS/Augumentation satellites support; accelerometers, gyroscopes, magnetometer, altimeter - for inertial navigation indoors and other locations with weak satellite signal
    - 2G/3G/LTE
    - DVB-T/T2/H/SH (or equivalent US TV broadcasts) tuner with internal antenna

    Premium models power adapter with:
    - additional USB3.0 BatteryCharging/PowerDelivery ports (when the laptop is disconnected those will only provide power to other USB-powered devices; when the laptop-or-another-USB-host is connected a USB3.0 hub in the power adapter will provide also USB connectivity to the connected devices (like a docking station); switch to choose whether the power adapter USB ports should remain powered when no USB host is connected
    - maybe integrate the bundled USB-to-Ethernet converter here (but this is kind of redundant if the HDMI port is of the Ethernet-enabled variety)
    - maybe also add a USB audio controler providing 6 jack analog jacks (for 7.1 output, line-in, microphone)

    Other additions (some of which not very realistic for the time being):
    - Anti-glare matte display (if it isn't already of this type)
    - Fanless design (if it isn't already of this type)
    - Multi-touch screen with support for 10 fingers+2 palm-restings and maybe stylos/handwriting
    - Touchpad occupying the whole surface below the keyboard with support for 10 fingers+2 palm-restings and stylos/handwriting; maybe even a second screen (for customizable buttons, auxiliary information like level map, etc.)
    - two multi-megapixel back cameras with autofocus, xenon flash, night-mode video illumination, etc. (just like high end phone) for stereoscopic pictures and 2x1080p60 (3D) video
    - two 1080p60 front cameras (for 3D mode) - either with separate illumination or utilizing the keyboard illumination
    - integrated Kinect-like gesture recognition system with sensors and array microphones
    - two picoprojectors on the back (for 3D mode)

    Let's hope the above gets implemented in the Haswell (or AMD 28nm) Zenbooks. However, those are not deal breakers (but especially the port section is cheap to do, so kind of expected), so I congratulate ASUS for the Zenbook Prime!

    I can see that its kinda pointless to have an ether net port on an ultra portable device but I can also say that sometimes its good to have one. Like trouble shooting connection issues making sure its not something interfering with your wifi or if you want to reduce latency. I have a quick question, how does the display compare to the screen on the new ipad? I'm looking to get something to replace my asus 1201n, and I'm kinda interested in this thing. although it would be nice if it had a dedicated gpu :-/ Reply

    this model has dedicated gpu

    I agree.
    The lack of a gigabit ethernet port is a killer. It means copying videos etc from you desktop computer to this will take 10 times as long.

    a gigabit to USB 3.0 adapter will work fine. USB 3.0 is quite a bit faster than gigabit ethernet. Currently we have a DELL XPS13 package for our users that includes the USB 3.0 to gigabit ethernet adapter, they appear to run at full speed transferring 100MB/s with no issues. Reply

    Thank you for making sense, unlike all these complainers. Most of the additional connectors a person specially needs can be found in the form of adapters and port expanders. Reply

    A Gigabit ethernet adapters as it should also speeds up for USB 2.0 users quite a bit. Easily beets 100Mbit/s any how. Won't do near 1 Gigabit/s however. But it should work as fast as your basic home-user NAS. If you need more you probably has direct attached storage or even fibrelink so :) Nice to see USB 3.0 get native, and yes it's fast enough for most users and are capable to extend things like Ethernet, basic storage.
