ASUS N61Jv-X2: Optimus GT325M Meets Arrandale
by Jarred Walton on March 13, 2010 10:00 PM ESTASUS N61Jv-X2 Battery Life
Like the Dell Inspiron 1564, the N61Jv comes with a 6-cell, 48Wh battery. ASUS doesn't specify a battery life for the N61Jv (that we could find), but users are reporting up to four hours of battery life in light loads and around two hours for movies. We calibrated the display for ~100nits (a setting of 41% results in 94nits brightness) and ran our standard battery life tests.
The battery life of the ASUS N61Jv is very similar to the Inspiron 1564, but it lasts 5-15% longer depending on the task. Video playback results favor the N61Jv more than the idle/internet tests, which is interesting since all of these tests use the Intel HD Graphics in the i5 CPU. Of course, the N61Jv battery life pales in comparison to CULV offerings, which can last more than twice as long. If you want a long-life mobile solution, the N61Jv isn't a great choice, but by the same token you can't come anywhere near the performance of the N61Jv with a netbook or CULV platform.
Looking at the relative battery life does provide a bright spot in an otherwise ho-hum set of charts: the N61Jv with i5-430M provides 12% better battery life than a previous generation Core 2 Duo + 4500MHD combination. In fact, the only laptops that provide better relative battery life are CULV designs (and Atom, though we didn't include Atom results in this review as netbooks are in a completely different classification). If ASUS had included a 65Wh battery, the N61J would be pushing into 5+ hour territory.

Not just that, but you have to be sitting RIGHT in front of the screen at the correct elevation in order to see the movie well. I have the latest powerDVD 9 Ultra and the movie looks like garbage AT BEST. I'm going to post a video on youtube so you can all see what I'm talking about...It's definitely a dealbreaker for some. For me, well I found this out after I bought it but DVD movie playback is not why I got this.
Does explain the lack of a Bluray drive though.
Gaming looks great btw.

I take it back. I turned off AVIVO hardware acceleration in powerDVD and made some fine tuning and it looks great... my bad.bobjones32 - Sunday, March 14, 2010 - link
With all this optimus tech talk, it's dissuaded me from purchasing an m11x. The m11x has the 335M, compared to the 325M in this laptop, and I'm wondering if anyone knows how much they differ?16" mammoths just don't interest me. I really want something portable like the m11x, with it's fantastic battery life, but I want some options to pick between.
1) Any chance that Anandtech will be reviewing the m11x? I was surprised it was never covered beyond the CES reveal.
2) Any word on the 335M extending beyond its apparent m11x exclusivity any time soon, in case it's noticeably faster than the 325M?

I second that as well - I'm putting off on the m11x because of Optimus and the relatively lowsy CPU spec. Hopefully it'll get a refresh sometime during summer. But I'm interested in seeing a review from Anand nonetheless.Fastidious - Sunday, March 14, 2010 - link
I was originally concerned a bit about that as well but got a M11x anyways. I keep reading reviews just to make sure I didn't make a bad choice. Even this much larger system seems worse in games albeit better in CPU heavy tasks. Optimus is cool and I wish I had it but it really isn't that bad having to manually switch GPUs(just press fn+f2 on the M11x). Unless I'm plugged in I'm rarely gaming heavy stuff and I'm instead in conserve energy mode with the Intel GPU, less bright screen, etc. The CPU in the M11x is the weak point but the battery life in it is great so it depends what kind of balance you want. I don't think there is any laptop with a great CPU and great battery life in a smaller form factor. I get around 6-8 hours with decent screen brightness, wireless and just general browsing/word/light games on the Intel GPU. You can game just about any modern game but you might need to tweak settings(often specifically CPU heavy settings such as shadows) or lowering the resolution a bit but doing that doesn't bug me.http://www.notebookreview.com/default.asp?newsID=5...">http://www.notebookreview.com/default.a...are+m11x... is the best review of the M11x I've seen

M11x has a faster GPU for sure, but the problem is CULV -- even overclocked -- can start to become the bottleneck. We're still waiting for a review sample; Alienware has said next month due to demand. It's a promising unit, for sure, but the lack of Optimus really makes it like a faster version of the old UL series.hagen81 - Sunday, March 14, 2010 - link
at notebookcheck you have a list of mobile graphic cards as well as some benchmarks, there's quite a diff between 335M and 325Mf4phantom2500 - Sunday, March 14, 2010 - link
Is this computer able to power down one of the CPU cores? If so what kind of difference does that make to battery life? Seeing as this is an Arrandale CPU with hyperthreading, 1 core should be plenty fast in battery mode.lloyd dd - Thursday, March 18, 2010 - link
it would be cool if the i5 had a mode in which you could power down 1 core and turn off turbo and underclock the active core.that plus optimus should give great battery life, with the performance when needed.

Arrandale can put one core into a deep sleep state, but just how far that goes is difficult to say. Obviously, the standard Arrandale with the Intel HD graphics draws more power than CULV + GMA 4500MHD, but it also appears to draw quite a bit less power than an older Core 2 + 4500 laptop (see relative battery life chart).
