ASUS K53E Impressions and User Experience
Last week’s ASUS U41JF review is going to be the most interesting comparison to the K53E. Sure, that notebook only comes with a dual-core Arrandale i3-380M, but the 15% CPU overclock option, 83Wh battery, and GeForce GT 425M Optimus graphics give it a leg up on the competition. Yes, i5-2520M is going to be a faster CPU, but everywhere else I’d rate the U41JF as the superior laptop. Before we get to the benchmarks, though, let’s take a closer look at the K53E.
The exterior and interior colors are an interesting shade of brown—almost a coppery color in the right light, and at other times the notebook can appear black. The lid is a textured plastic, which means that in normal lighting fingerprints don’t show up quite so well. Unfortunately, it also means that you can't easily wipe it clean with a microfiber cloth, and flash photography often brings out the greasy prints hiding in the indentations. I still prefer the silver styling of the U41JF (and other ASUS laptops), but the K53E doesn’t look bad.
The 15.6”-screen chassis happens to be one of the least expensive laptop sizes these days. It’s large enough that manufacturers don’t have to work as hard at cooling or internal layout, but still small enough that they’re not wasting a lot of material. Unfortunately, our biggest complaint with the 15.6” LCDs floating around is that most are of the 1366x768 variety, and the K53E falls into that classification. We’d really like to see some better resolutions in 15.6” notebooks—even 1600x900 would be better than 1366x768—but then we’d also like to see LCDs that have a reasonable contrast ratio, maximum brightness, and color quality. In case you were wondering, the AU Optronics B156XW02 v6 panel used in this particular notebook has none of the good features we’re looking for and all of the bad. Yuck.
The keyboard is a traditional ASUS chiclet design, with the numeric keypad wedged in on the right. Like other notebooks, we’re not happy with the 10-key layout, mostly because the zero is half-size and the right cursor key overlaps the 10-key space. It’s not so egregious a flaw that we’ll spend a paragraph or two ripping on the layout, but there’s still room on the sides that ASUS could have used to give us a full 10-key with no compromises. Typing action outside of the 10-key is fine, and the dedicated navigation keys in the top-right (Home, End, PgUp, and PgDn) are certainly welcome.
Something we do like with the K53E is the touchpad. It’s big enough to be useful without being so huge that you accidentally brush it while typing (and as usual, you can configure the touchpad to detect keyboard use and go to “sleep” for a short interval after typing to mitigate that particular problem). The tracking surface is also a nice, smooth texture and there are—gasp!—dedicated left and right mouse buttons. Why can’t we get these on the U-series? The palm rest is a nice metallic brushed aluminum finish, and the touchpad is slightly inset and has a different texture to help you find it without looking.
Rounding out the package, the speakers are still a weak point—every time I fire up a game or play some music on Dell’s XPS 15 (the L502x now has Sandy Bridge CPU support; review is coming soon!), just about every other laptop sounds horrible in comparison. Another big gripe I have is with the position of the AC plug. It’s on the left side, but instead of being at the rear of the notebook (as is usually the case), it’s located in front of the exhaust port. When plugged in, the AC cord gets in the way of the Ethernet, HDMI, and USB port on that side—or you can snake the AC cable around back, in which case you’re partially blocking the exhaust port. It’s not a big enough problem that you can’t use the ports while plugged in, but it’s just a weird design decision, particularly when you consider that nearly every other laptop puts the AC connector at the far back of the chassis.
Looking at the whole, the K53E is a very reasonable notebook for the price. It’s not going to outperform quad-core SNB or gaming laptops, but it will run just about everything you might want with performance to spare. The price also puts it into competition with many inexpensive laptops, and it’s a major reason why we think AMD’s Brazos platform at $600 or more is a dead end. Even the i3-2310M will run circles around an E-350 (in both applications and games), so the only area where E-350 comes out ahead is battery life. With a better LCD (or at least a better resolution) and more connectivity options (e.g. USB 3 and eSATA), this could be an inexpensive desktop replacement for people that don’t need maximum CPU and/or GPU performance. With the current design, the K53E is a decent mainstream offering that boosts performance and battery life compared to the previous Arrandale offerings.
Is that enough to warrant spending $100-$200 more compared to AMD Athlon/Brazos/Turion laptops—or Intel’s older Pentium and Core i3 systems? When you factor in the performance and build quality, I’d actually say that the $720 K53E-B1 is going to be a better all-around notebook than most of the $400-$500 laptops you can currently find at places like Best Buy. But then, I’d be far more likely to save up the remaining $80 to get a better GPU, like in the ASUS U41JF, or wait another month or two and see what AMD’s Llano APU can do for budget laptops. If you’re chasing lowest cost, small size, and battery life as your primary considerations, it’s difficult to beat HP’s dm1z, but as soon as you start customizing and approaching $600 (i.e. the Sony and MSI Brazos E-350 laptops), you have to look at the whole market and not just focus on netbooks.

Brazos C-50 starts at $325, so it's within spitting distance of the Atom N550 (dual-core), and it still has a substantially better IGP -- though it's mostly useful for video as opposed to gaming on the C-50. C-50 is also a lower power and better battery life option, though it may not match the best Atom netbooks. Still, I'm not sure most people need more than 10 hours of battery life, which is what we're talking about at this point.AMD's E-350 is better/faster, but it's also more expensive. I'd be quite surprised if Atom netbooks offered better audio latency. Only thing really missing is a good ASUS equivalent of the 1001P, only with C-50. Right now, the only 10.1" C-50 (or Brazos) netbook comes from Acer, who doesn't have the best reputation. If you're interested, though, the Acer Aspire One 522 is on sale for $300 at Micro Center right now.

Have you ever tried an Atom? - if i would say you are a very patient man :)There is absolutely none in my family, with very patient female computer users i tell you, who havnt complained about the speed for basic task like surfing and office use.
In my entire life i have met one person who didnt complain - all other - who thought all computers were the same - have complained. Atom just showed them - who did forget about the old age and windows 95 on 8Mb ram, that computer actually can be different.
What i am pretty comfident about is, that all those user would have been pretty sattisfied with an e350, and stayed in their beliewe there was no difference.
I think it just underlines that Intel and AMD have trouble for the future. The cpu/gpu is just fine as they is now. Then there is just the fight for cost, and it means lower earnings on the traditional markets.

I was perfectly happy with the one Atom system I have used extensively - the carputer I built in my last car was based around an Atom 330. with 1GB RAM and a 200GB 7200 RPM HDD the only time there was ever any delay running the Centrafuse front-end interface was when a module was first loading after a restart. So for limited uses Atom is fine, so long as the software and experience are designed for that level of performance.krumme - Monday, April 11, 2011 - link
Yeaa, and my atom stream audio fine, and does not feel slow as long as i do not touch it.Atom was not build for anything but tv boxes, competing with arm. And therefore it does not work when anandtech, promotes sb at the expense of bobcat, because it indirectly leads the consumers to tv box computer power. And that is the unintended effect of theese articles.

So Atom running a custom OS will be much better, obviously. Heck, even Atom chips (by PC standards) are going to be twice as fast as the best smartphone chips -- not on the GPU side, though, but that's a different story. But if you were to go out and buy a laptop for use as a Windows PC, there's still a big gap between $400 laptops and $700 laptops -- more than a 2X increase in performance for less than double the price.My experience is that given the choice (i.e. money not a consideration), no one would want less performance from their laptop. SNB dual-core should be good enough to fit in 13.3" laptops that weigh around 4 lbs., and priced at around $800 (or less) that's a great portable PC. Bobcat will go into smaller devices and offer slightly better battery life, but it's still slower (too slow) on some tasks -- e.g. video transcoding, Flash browser games, and anything else that's computationally intensive will be much better on SNB. So again, Brazos is basically for those who value price more than most other areas.
On a related note, I'd be shocked if any major business tried to replace current generation Arrandale laptops with Brazos laptops. Heck, they wouldn't even replace Core 2 Duo laptops with Brazos. Businesses want a balanced laptop, generally speaking, and right now Intel gives you more performance with good battery life for a reasonable price. AMD competes on the desktop and laptop with lower prices, but when productivity is money, why would you save $150 only to have your employees waste hours of time over the next year? (Well, they'll waste time regardless, but they'll waste even *more* time waiting for a slow computer.)
Long-term, it will be very interesting to see what happens with Windows 8. Windows 7 can run on Atom, but it's clearly a different experience than Win7 on even something like CULV or Brazos. ARM-based SoCs are sort of Brazos, except they're even slower on the CPU side of the fence (and slower on GPU as well). Win8 will need some major changes relative to Win7 to make it viable on tablet and laptop devices running such SoCs.

IT is not a strategic subject for top management anymore.A few years back, they would spend time talking TCO, cost outsourcing, but today is different.
They just dont want to hear about it, and spend valuable time on it. For good reason.
SAP is running for everyone and his brother, the oursourcing is in place. Who cares if its a Dell or HP machine except in IT.
And the IT director, who ofen is an economis, hardly knows what a CPU is. It matters so little no one cares just a few stop up the chain.
The replacement of computers is just done regulary say every 3 years, and what Dell/HP chooses to put in their computers is their business.
If something is interesting about the computers today its screen, keyboard, battery and foremost quality.
The cost differences for a brazos compared to a sb is so slim, it doesnt matter. But lets say the next brazos 28nm q4?, have nearly double the batterylife and a solid turbo, then i think there is a chance we will se a lot of ultra portable business laptops with them.
Except for 10% of the business users i think we are waiting for the HD not the cpu. Therefore i think we will se more cheap ssd and even more noise and battery friendly cpu/gpu in the next generation - standard roll out - business leasing deals.
But as said, for the professional side its just mostly TCO today, and for the consumer side its just more and more cost, cost, cost. Perhaps they are saving for an IPAD3 ? :)
