ASUS U30Jc: Refining Thin and Light Performance
by Jarred Walton on May 18, 2010 11:23 PM ESTASUS U30Jc Performance
As an update of the older UL30a, the U30Jc is a great improvement in performance. It includes discrete (switchable) graphics like the UL30Vt, only with Optimus to make the switching seamless. It also bumps the CPU up from CULV to a full Core i3 model, with substantially faster performance and a better IGP. Where it differs from the UL30a is in the inclusion of an optical drive, which does make the U30Jc thicker and heavier than the older model. It's a good feature if you want to watch DVDs or load games onto the system without using an external drive, but it's a change not everyone will like. On the other hand, the performance improvements are a clear win.
In terms of application performance, the U30Jc lags slightly behind the i5 equipped laptops like the Acer 5740G, ASUS N61Jv, Dell Inspiron 1564, and Lenovo ThinkPad T410. That's right in line with the difference in CPUs: the i3-350M runs at a constant 2.26GHz; the i5-430M has the same 2.26GHz stock clock but Turbo Boosts up to 2.53GHz, and the i5-520M has a 2.40GHz stock clock and can Turbo up to 2.93GHz. Compared to the older Core 2 platforms, we see the i3-350M easily beating the SP9300 and P8600 processors in the HP 5310m and Dell Studio 14z. The gap ranges from 15% in single-CPU Cinebench up to 40%+ in multi-threaded Cinebench, with other results falling in the 25%-35% range. PCMark05 has the 14z nearly on par with the U30Jc, but it tends to weight things a bit funny so we'd pay more attention to the 31% difference in PCMark Vantage.

I'll try running that once as a reference point. Is there a way to loop a PowerPoint slide? I'm guessing that's what you mean: external display, PowerPoint, and battery power right?Furuno - Friday, May 21, 2010 - link
Yes. And for looping the slide, you can set it by going to the Slide Show menu and pressing the Set Up Slide Show Button, and there's should be a loop continuosly checkbox in the dialogue box. Oh, and you'll need to adjust the Advance Slide option under Transition Menu.Best regards,
Furuno

Excellent article, thanks for the thorough and honest review.The only thing that keeps me away from buying these (or any) laptops is the abysmal display quality.
Maybe you guys could literally set the bar for the manufacturers ?!
You could add bars to the display graphs that would say: abysmal, decent, good, industry leading quality or something similar.
That way we'd see at a glimpse what is worth buying and what is not in this category.
Hopefully it will encourage more manufacturers to give higher priority to a good panel instead of those extra few percentages of processor performance.

4 hours of DVD playback time isn't so bad, though the idle state gives us a 550 minute battery life.The important thing with a laptop, which is being challenged lately by the latest cell phones is application speed.
An example:
Task: Taking an image on site and sending it to all your friends.
I used to use laptops for this, way before cell phones had cameras....I used to take a picture on a digital camera, then upload them to my laptop by USB. I then would have to find some Wireless Network out there...or Wired Connection to deal with the internet...and then send an email to everyone with Attachment. This takes forever on a laptop....
Today I can just get to the site or target location.....I can sneak around and take an image with a phone....and then I can use the 3G coverage of an area and send an email with that attachment to everyone to everyone in my list...All in the time it takes for a laptop to start up and set up.
The more laptops try to take the role of mobile-desktops, the farther they will drift from the concepts of what mobility (and stealth) brings to the table, and the slower they will become each generation against cell phones.
There is a reason why more people today buy an iPhone or GooglePhone these days....
Specially the idea that voice recognition software is becoming more and more common....Its fun to be able to say something and have it record a note, or dial a number....
I can say "I need to buy eggs and bread" and walk into a store and play it back.....than having to type it.
The more they try to make a laptop into a mobile-desktop, the more mobility it actually loses and the slower it becomes vs the cell phone craze...Yes, its amazing how a $3000 laptop doesnt hold a candle to the speed one can do things on the IPhones and other Phones out there that compete against it.

Seriously: LIGHT at almost 5lbs?I hope Asus paid a lot for this piece - it would be awful to realize you just made a complete fool of yourself publicly for chump change...

Can you get your hands on a PL30JT?Supposed to have an i5 processor and a matte screen, maybe a little better battery life as well.
I would love for you to review it (or even a quick comparison with the U30JC).
Thanks,
Alex.

very very useful article for me!I've found Vaio S Series a good competitor against this laptop...same weight...same processor...same graphic chip... but there are a few articles about S series.. and seriously... This website is one of the few websites I can trust :)
So can you read an article about S series? I love U30jc but as you mentioned it has a poor screen... I think vaio makes better displays...
thanks anyway...
