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.

    Why did you not do any battery life comparisons of optimus enabled vs disabled for this laptop? It would have been really nice to see that so we can see the actual direct benefit of optimus on this laptop instead of having to compare it to another laptop from a different vendor using different specs.
  • JarredWalton - Monday, March 15, 2010 - link

    Optimus is always enabled, but the GPU is shut off unless needed. The only way to test battery life with the GPU enabled would be to run a test that uses the GPU. That means games, CUDA apps, or certain video decoding scenarios. The problem is that the video decoding is now all done on the IGP without any glitches, so the GPU isn't needed.

    so it runs twice as fast around 60fps at ultra low and low resolutions on a low screen resolution..., yuk. Yes it is better than intel graphics and will play WoW like games fine but this is no gaming machine.
  • JarredWalton - Monday, March 15, 2010 - link

    Which is why I include results from the same games at Medium and High detail, and as you can see it runs most titles at such settings with more than reasonable frame rates. Obviously it's not faster than GTX 260M, but 260M is able to run most titles at high details and 0xAA at a resolution of 1080p; for a 1366x768 panel there's no need to get much more powerful than the GT325M. You'd be better off upgrading the LCD first to something where the graphics quality difference wouldn't look washed out.

    Though not specifically this laptop, I bought the N71jv-x1 from newegg a couple of weeks ago. Similar specs (larger screen, switched out core i5 for core i3, runs at 1600x900). I am able to play Left 4 Dead 2 with all graphics options turned high at the resolution of 1600x900. Also, my battery has similar run times.

    2 problems ive noticed though, and I am not sure if I am the only one: After the laptop has been brought back from suspend there is a greater chance for graphical errors when switching between gpus (specifically in WoW, though I have noticed it in Batman Arkham Asylum as well), and ASUS put a lot of bloatware on this thing. Some of it useful, the majority of it isnt.
  • nortexoid - Monday, March 15, 2010 - link

    They need to offer a high resolution version.
  • mikeev - Sunday, March 14, 2010 - link

    I've been spoiled by a fingerprint sensor on my work PC (to hell with passwords), and I noticed on the Asus website that it lists the N61jv-X2 as having an "Optional" fingerprint sensor. Has anyone seen this variant? I'd gladly pay an extra $50/100 for this feature.
  • JarredWalton - Monday, March 15, 2010 - link

    Most laptops will charge about $25-$50 extra for a fingerprint scanner. We don't have the i3-330M or i5-520M N61Jv models yet, nor the Blu-ray version, but they're all supposed to be in the works. The reviewed X2 model is for and thus won't have the scanner, but keep an eye out and we'll likely see the other options start to show up. I'm curious as to where they'll position the scanner as well... between the mouse buttons, or somewhere else? It would be good to get it in the touchpad and get a separation between the buttons IMO.
  • mikeev - Monday, March 15, 2010 - link

    That's a good question. I've seen lighted variants now (LED-pipe around the scanner) for feedback these days. Hopefully it's one of those. I actually prefer it to be in the lower right hand corner myself.
  • Hrel - Sunday, March 14, 2010 - link

    IF it had a 1600x900 screen or better; hell, throw in a higher capacity battery give me a 1600x900 screen and I'll gladly give them an extra 100 bucks!
