ASUS N61Jv-X2: Optimus GT325M Meets Arrandaleby Jarred Walton on March 13, 2010 10:00 PM EST
It was only last month that we got our first taste of NVIDIA's Optimus Technology, courtesy of the ASUS UL50Vf. We were without doubt impressed, but there was a small issue with the test platform… or perhaps a not-so-small issue. The UL50Vf uses a CULV processor with G210M graphics—nothing spectacular in performance, but good enough for a reasonable system that can last upwards of 10 hours on a single charge. The problem is that the UL50Vf is a 15.6" notebook, and while it's not as bulky as other 15.6" offerings we have to admit that the pairing of CULV and Optimus cries out for a smaller chassis. Today, we're reviewing our second Optimus notebook, but while the chassis isn't any smaller—in fact, it's slightly larger with a 16.0" LCD—the other changes make this a much better platform. We're going to cut straight to the chase and hit the spec sheet.

Gone is Core 2 CULV, replaced by a much, much more powerful i5-430M processor. Sure, CULV overclocked to 1.73GHz provides reasonable performance (as with the ASUS UL series using the Turbo33 feature, or Alienware's M11x), but switch to Arrandale, bump the clock speed up to 2.26GHz (2.53GHz with Turbo Boost) and add Hyper-Threading and there's simply no competition. We'll see this later when we get to the benchmarks.
The CPU isn't the only upgrade, however; ASUS pairs the faster CPU with a significantly faster GPU, the GeForce GT325M. Now, the G210M is a much faster GPU than any IGP. We measured gaming performance that's at least 40% faster than the 9400M, and as much as 100% faster; average performance is about 60% faster than the 9400M. And to put things in perspective, the 9400M is currently the fastest IGP solution, coming in anywhere from 10% to 90% faster than the HD 3200 in our testing (average is about 25% faster in games); the HD 4200 is only a slightly faster clocked version, trading blows with Intel's new HD Graphics but not beating the 9400M.
Where does the GT325M rank? It has 48SPs compared to 16SPs on the 9400M; core clocks are about the same as the 9400M, which means it has almost three times the Shader/GPU processing power. It also has 1GB of dedicated GDDR3-1400 (at least in the N61J) and a 128-bit bus, giving it a dedicated 22.4GB/s; IGP solutions have to get by with sharing half as much memory bandwidth with the CPU and the rest of the system. What we're looking at then is performance that should be more than twice as fast in most games (assuming the game is GPU limited). And of course, Optimus Technology means that the GPU can turn off completely when it's not needed, so you can get maximum battery life from the Intel IGP when you're mobile.
Other changes relative to the UL50Vf aren't quite as significant, but they do help performance. ASUS ships the test model with a 500GB 7200RPM hard drive; our system uses a drive that Seagate touts as using "only .05% more power than a 5400RPM drive". We're not sure what 5400RPM drive they're comparing the 7200.4 Momentus with, but it's definitely faster than 5400RPM drives so we're happy to lose a bit of battery life if it means snappier performance, considering the other component choices.
Speaking of battery life, the above upgrades do not do the N61J any favors when compared with CULV offerings. ASUS provides a 48Wh 6-cell battery with the N61J, and the combination of a smaller battery and a more power hungry CPU+IGP means you're looking at around 4 hours of battery life best-case scenario. Obviously this isn't meant to be an all-day mobile solution, and when we look at all of the specs together 3-4 hours of battery life for typical tasks is quite good. This system can function quite well as a desktop replacement, provided you're not trying to run workstation type applications. We do wish ASUS was able to cram in a larger 65 or 84Wh battery like the UL series, but we understand the need to keep BOM costs in check.
The particular variant of the N61J that we're reviewing is the N61Jv-X2. If you're not familiar with the ASUS nomenclature, the "X" following the main model name indicates a specific build for a major reseller, in this case Amazon. Other variants of the N61J will feature i3-330M, i5-520M, or i5-540M processors; differing HDD capacities and RPMs; and Blu-ray support on some models. We'd love to see the N61Jv with a Blu-ray combo drive, but before we go Blu-ray we'd like to see a better LCD—1080p in a 16" LCD is a perfect fit for Blu-ray in our book. Such upgrades would naturally have a significant impact on the pricing, so taken as a whole the X2 model is equipped very well. It's currently available (and in and out of stock) at Amazon for $899.
$900 is a major price point target with competition from every major manufacturer. We've recently looked at the Dell Inspiron 1564, which is going to be a focus for our performance and value comparisons. We've got reviews of other vendors in the works as well, including a Lenovo ThinkPad T410 and the Acer Aspire 5740G. What sets the ASUS apart from the competition, beyond NVIDIA's Optimus Technology, is the overall package. The warranty is a great example: ASUS provides a standard 1-year global warranty with accidental damage protection (one incident only and one-way shipment for accidental damage), two-way shipping for the customer, and a 30-day zero bright dot guarantee on the LCD. Would we prefer a 2-year warranty? Sure, but every little extra bumps up the price—Amazon does offer a 3-year warranty with the N61Jv for $1030 if that's important to you.
Rounding out the package are the usual extras, plus a few noteworthy additions. ASUS provides HDMI and VGA outputs, Gigabit Ethernet, 802.11n wireless, a flash memory reader, and an ExpressCard/34 slot. In addition, ASUS provides a single eSATA port and two USB 2.0 ports. The big extra is that ASUS has added an NEC USB 3.0 controller for one more USB port on the left side. We unfortunately didn't get the necessary hardware to test the USB3 performance, but ASUS' internal testing with a USB3 hard drive enclosure shows transfer rates over three times faster than USB2; at that point, they run into a conventional HDD performance bottleneck. USB 3.0 support is in its infancy, but the inclusion of the feature on the N61Jv makes it a forward-thinking design and we're sure users will be happy to have that extra down the road. About the only area where ASUS cut any corners is the LCD; it's yet another low contrast 1366x768 model—not the end of the world, but nothing to brag about either.

utkal - Monday, March 15, 2010 - linkI do not understand why the hell Asus only hosts 1366x768 resolution lcds in their laptops. They have ONLY ONE laptop of full HD upto 16" screen size with a price of $1440 (approx) ! wtf ! In a 16" laptop what can be worst than this resolution lcd.
Sorry, but how AT reviewer said, we did not found anything bad about this laptop ? funny ! Do not you know the 1366x768 resolution makes the life hell if you use the laptop for work. Yes, if the laptop is bought ONLY TO GAME then its ok.
JarredWalton - Saturday, March 20, 2010 - linkRTFA. From the conclusion:
"The worst aspect is the mediocre LCD panel, but when everyone uses lousy LCD panels (at least in sub-$1000 laptops and notebooks), we can only complain so much. The LCD panel and somewhat small battery capacity prevent us from giving the N61Jv our top Gold award...."
I've looked at dozens of laptops, and I've got a bunch more I'm working on reviewing. The ASUS Eee PC 1001P and the ASUS G73J are the ONLY laptops I have right now that don't have a similarly lousy LCD. Sure, you can get high-end laptops with good LCDs (Dell Precision M6500), but for consumer notebooks it's a lot harder than it should be.
jackwhitter - Monday, March 15, 2010 - link"Today, we're reviewing our second Optimus notebook, but while the chassis isn't any smaller—in fact, it's slightly larger with a 16.0" LCD"
it has a larger monitor with the same low resolution as a 11" monitor. why are companies so insistent to use such a low resolution on these larger screens? what happened to 1600x900?
JarredWalton - Monday, March 15, 2010 - linkOne factor is cost and another is gaming performance. The GT325M will run most games at 1366x768 with Medium/High details at good frame rates. If the native LCD moved up to 1600x900, gaming performance would drop 37%. But the bigger issue is cost, I'm sure.
utkal - Monday, March 15, 2010 - linkDear, At least I do not think that people buys a laptop ONLY TO GAME. The primary purpose of laptop should not be gaming. And If you will work with applications like visual studio, you can hardly see few lines of code with a 1366x768 resolution where the vertical resolution will taken up by application titlebar, menubar, various toolbars, status bar and finally OS's taskbar !!! Now understand how difficult it to work with such low resolution laptop.
No doubt other components are excellent with this price range, but they MUST have option for higher resolution screen, instead of making laptops for only GAMERS.
erple2 - Monday, March 15, 2010 - linkI'm sure that the only issue is cost. Many people will look at this computer at 900 dollars compared with 1200 for the one with higher resolution LCD and commensurate faster GPU and just buy the 900 dollar one.
I would be more than happy to spend an additional fee for a better screen and faster discrete GPU (200-300 is about what I'd pay, I think, unless the GPU was _significantly_ faster, and/or the screen was _significantly_ higher quality/resolution).
jasperjones - Monday, March 15, 2010 - linkI refuse to buy products that don't have full Linux support. Linux support is much more important to me than a 10-15% difference in battery life.
What happens if you try to install a recent Linux distro such as Ubuntu 9.10 on an Optimus laptop? Unfortunately, a quick Google search didn't provide any insights. (Btw, one of the top hits of my search was the launch article on Optimus here on Anandtech. There, Jarred asked virtually the same question.)
GeorgeH - Monday, March 15, 2010 - linkAFAIK an Optimus laptop should be considered a Win7 exclusive device, but confirmation would be nice; hopefully JW comes through.
Quote from JW Feb 9:
"Some of you asked about Linux support ... at present, NVIDIA is focusing on Win7 ... we're not even sure what would happen if you try to install Linux ... we're going to quickly check and post the results."
Either we missed the promised update or our definitions of "quickly" are a little different. ;)
JarredWalton - Monday, March 15, 2010 - linkI did actually try Linux on the UL50Vf, but I neglected updating the article. Here's what I just put in there:
I did actually test what happens with Optimus laptops and Linux. Even using an older 9.04 installation of Ubuntu, everything works as expected... which is to say, you can run Linux but you won't get the Optimus GPU. Since there's no direct connection of any display to the GPU, Optimus is required to move rendered content from the G210M to the GMA 4500MHD display buffer. As noted above, NVIDIA is currently focusing their efforts on making Optimus work on Windows 7; it's possible they will move to other OSes down the road, but they are not committed to doing so. If you want to run Linux and you want to use a discrete GPU, Optimus Technology won't work. Perhaps some skilled Linux community folks can figure out a way to do Optimus-like technology on their own, but given the level of detail required to interface with the GPU and IGP we see that as unlikely.
If you're one of the few people that want to run Linux and use a discrete GPU, then Optimus is definitely not going to make you happy. If all you want is to dual-boot Linux and you're okay with running it off the Intel IGP, you'll be fine.
