Introducing the HP dm1z

HP's been on board AMD's ultraportable bandwagon since the chipmaker first shipped the underwhelming Congo platform, and HP continued to produce reasonably compelling not-quite-netbooks with the Athlon/Turion II Neo-equipped Nile platform. But now that AMD has made a concerted effort to dethrone Intel's Atom with Brazos, HP has been able to produce a true netbook competitor. We have the shiny new dm1z equipped with the AMD E-350 in our hands: is this the netbook we've been waiting for?

HP has refreshed their dm1 line with AMD's Fusion APUs, but what else does their shiny new netbook bring to the table?

The most interesting thing about the HP dm1z, right off the bat, is that it's the first netbook we've reviewed to feature AMD's Fusion APU, and HP equips the dm1z standard with the most powerful one in the lineup. The AMD E-350 comes with dual 1.6GHz Bobcat cores, 1MB of L2 cache (no L3), along with a Radeon HD 6310 GPU integrated into the processor die. The HD 6310 is more or less an on-die Radeon HD 5450, with 80 DirectX 11-class stream processors in AMD's VLIW5 configuration and clocked at 500MHz.

The E-350 features a single 64-bit DDR3 memory channel capable of supporting up to two DIMMs for a total of 8GB of RAM. The whole shebang has a TDP rated at 18 watts, which may seem like a lot until you remember the IGP is built into the processor instead of the Northbridge, and instead of having a Northbridge+Southbridge combo as is traditional for AMD, the E-350 requires only the Hudson FCH, a tiny chip that includes just enough SATA, USB, and PCI Express connectivity to get by. Besides, TDP isn't the same thing as actual power requirements—18W looks to be close to the maximum the APU can draw.

Given the small form factor of the dm1z and its intended market, HP is actually fairly generous in its stock configuration. At the time of writing, HP offers a "free upgrade" from the base 2GB of DDR3 and 250GB 7200RPM hard drive to 3GB of DDR3 and a 320GB 7200RPM hard drive; this is the configuration you're most likely to see in retail. The Western Digital Scorpio Black is pretty fast for a mechanical drive, too, so it's nice to see HP step up and offer this 7200RPM drive as standard. Connectivity is handled by Realtek Gigabit and 802.11b/g/n wireless networking along with a Bluetooth 3.0-capable Ralink chipset. About the only complaint we really have on this front is the lack of a separate microphone jack, but that's relatively small potatoes in the grand scheme of things.

    "only thing that hurts about using [it]" is separate from "only major dents [i.e. in the build quality/design]". I took out the last only for you, though. :)

    x120e is out.
    Any thoughts?
    I'm considering cancelling my dm1z order and getting a thinkpad instead
  • The Crying Man - Wednesday, February 23, 2011 - link

    I read somewhere that the only reason you'd get the x120e is for the matte screen, nipple mouse, and overall look since it runs warmer and has a slightly lower battery life compared to the dm1z.

    Whenever there is an article about Fusion APUs and praising how great it is, Intel fanboys begin to compare it to CULV, and Apple fanboys stand out to say netbook is out of the game and iPad saves the world.
  • swaaye - Thursday, February 24, 2011 - link

    What do you compare it to? You make it sound like it shouldn't be compared to the competition. And, perhaps this hasn't occurred to you yet, but everyone has different preferences.
  • Wieland - Friday, February 25, 2011 - link

    I find passive aggressive comments like nitrousoxide's just as annoying as the comparisons he mentions, but the issue is that the CULV laptops and iPads aren't the competition of this laptop at all. The cheapest CULV laptops are still quite a bit more expensive than the dm1z, and models with similar fit and finish are around twice the price. The iPad is completely different in form and function.

    It's apparent from nitrousoxide's comment that he understands that people have different preferences. The question is why does everyone feel the need to shout their personal preferences to the world.

    There's a new f.12 bios that tweaks fan to be much less of an issue!

    This netbook is the ideal area where it needs to be before Llano makes it debut. Seeing that I only use a computer nowadays for viewing podcast videos in Google Reader along with a little of Youtube, and connect the HDMI on my 32 inch tv, this would be ideal for me. I rarely use my DVD-RW drive, and ironically use more USB sticks for temporary storage, although I could use a 1TB external drive as well for music, videos, etc. I'm not saying this is the netbook king by any means, but a step ahead in the right direction for people who don't need all the flashy features that a laptop offers nowadays. Just my 2 cents on the subject at hand. Thanks for the review Anand, cause this netbook I'll be getting in the nearby future for sure.
