HP dm1z: Taking Fusion on the Road
by Dustin Sklavos on February 21, 2011 7:00 PM ESTFusion-Powered: Application and Futuremark Performance
This was my first experience with AMD's E-350 APU, a chip which has been the subject of some contention around here. Jarred and I are basically in agreement where performance is concerned and the general positive impact the chip can have on the mobile market: it's where netbooks probably needed to be all along, and should hopefully supplant Intel's lackluster Atom platform. Where we differ is our enthusiasm for it: Jarred feels Brazos was long overdue and isn't the quantum leap we were hoping for and expecting, which is a perfectly fair assessment. We needed Brazos a while ago, and AMD is late to this party.
That said, I'm happy AMD finally did show up. You'll see the E-350 isn't a massive jump forward from Atom, but it's enough of one to make the netbooking experience finally enjoyable instead of being a sluggish chore. Subjectively speaking, in regular use I found the dm1z to be nearly as responsive as my Lenovo ThinkPad X100e which is equipped with AMD's first generation Congo platform (though upgraded to an Intel X25-V SSD instead of the still-respectable Western Digital Scorpio Black mechanical drive.) So how does the E-350 actually fare when compared to mobile kit?
The first thing you'll notice is that while the E-350 generally cleans Atom's clock (the dual-core nettop D525 only comes out with a slight lead in the 2nd pass x264 encode), it's also generally about two-thirds as fast as the Nile platform's 1.5GHz Turion II K625. That's not too bad, but this is part of what Jarred's talking about, especially when you think about the Intel Core 2-based CULV kit that periodically kicks around the market (becoming stunningly rarefied). CULV hardware has also floated around the price point the dm1z is hitting shelves at, too, but it was fairly inconsistent. On the flipside, it does beat dual-core Atom equipped with NVIDIA's NG-ION, and this is a trend that's going to continue.
In 3DMark the E-350's integrated Radeon HD 6310 generally hangs out in the neighborhood of NG-ION, but it soundly beats Intel's last generation IGP (with better drivers and more stable performance to boot), and embarasses the Nile platform's Radeon HD 4225. That's not too surprising: in terms of raw GPU power the HD 6310 features twice the number of stream processors and a higher core clock.
If anything, the HD 6310 shows just how long in the tooth AMD's current IGP has really gotten: when it debuted as the 780G, it was a revelation, offering the best IGP performance bar none. The problem is that AMD just let it sit, offering new model numbers with no real performance increase outside of adding DirectX 10.1 support and bumping clocks slightly in some cases while serving us a warmed over Radeon HD 4550 in the form of the Radeon HD 5450 when they really should've just been integrating that hardware into their chipsets.
Ah well. With Brazos here now and Llano on the horizon, the era of AMD integrated graphics parts wearing out their welcomes should come to a close.

11.6" is close enough to netbook size that I have no issues calling it a netbook. I typically call 11.6" to 13.3" ultraportable, 10.1" and smaller netbook, 14-15.6" laptop, and 16" and larger notebook. However, notebook and laptop are almost terms that reflect the entire category of mobile computer, and netbook can just as easily mean "slower, smaller, and with good battery life" as it can "less than 10 inches".The Crying Man - Wednesday, February 23, 2011 - link
I thought 10" and under was a Microsoft restriction with regards to which edition of Windows OEMs could install. In the case of netbooks, they could only install Starter. Which is why I think HP, in another review, insisted that this isn't a netbook.Zoridon - Tuesday, February 22, 2011 - link
I bought my wife a ASUS 1000HE about 2 years ago. It came with a atom 280 1.66 ghz processor, 160 gig hard drive, intel onboard graphics and 1 gig of ram for about $380. It had a 10.1 inch 1024x600 screen and bluetooth. My compliants were many and I tried to warn her it would feel slugish after loading xp, antivirus, itunes, and whatever else she found to install. It will now serve as my bitorrent client machine because thats all its really good for, or watching whenever I find myself on a plane.Complaints:
1. Screen does not quite fit an entirew webpage so I have to scroll = wasted time
2. No gaming ability what so ever
3. Lack of flash support
4. Sluggish windows performance once you get a few programs running
This system blows it away in every aspect. Battery life is almost as good,
1. duel core processor that is 50 percent faster per core.
2. twice as much ram or triple as HP has offered
3. Modern windows OS
4. twice the hard drive space and not 5400 rpm
5. flash card reader built in
6. The screen is over an inch and a half larger with enough pixes to fit an entire web page
7. full size keyboard
8. Easy access to inner parts for do it yourself upgrades (RAM, Hard Drive)
All in all this is a hell of a improvement. If I were in the market to buy a computer for mobile use right now I'd buy this in a heartbeat. I can't wait till they go to 2nd generation and upgrade the processor speed to at least 2 ghz and incrementally improve the graphics and add USB 3. Did I mention bluetooth 3.0? I may even suggest the Army take a look at these systems for the SIPR machines (Secret) since we are not allowed to use uptical drives on those systems anyway. MIght as well remove them and have admins have some externals handy for a case by case need.

well at least it is available now in some EU parts.large consumer electronic vendors offer now the dm1z with 3gb ram and 320gb hd for approx 380eur, not that bad at all.

"Jarred's working on some additional gaming tests for his E-350 review"Once again I implore you to run some older game titles (from 2005 or thereabouts) that Fusion should be able to run at satisfactory FPS rates. Pick the titles that you used as your benchmarks back then so that your readers can see what's actually playable on Fusion platform.
Sub 20 FPS scores in modern games mean nothing (except to masochists perhaps), you've made it clear Fusion is incapable of running any modern game so please take some more time to show us what it *CAN* run.

And dont forget League of Legends. (max settings)pafnucy - Tuesday, February 22, 2011 - link
I have waited for Anand's review of dm1z with anticipation. I am quite disappointed, honestly.1. dm1z ships with HP CoolSense application for balancing noise vs temperature of the system. By wiping the HDD clean and then complaining about the fan noise the reviewer not only displays laziness but also disinforms the readers.
2. Other websites mentioned that the HDD performance is underwhelming. Here, the reviewer instead of running e.g HD Tune for 5 minutes just assumes that it's fast because it ships with a fast drive. For an entirely new platform, especially one that cuts corners to achieve low power consumption, it seems crucial to be wary of potential performance problems.
3. The entire review doesn't even mention sound quality. Are the Lantec speakers any good? What about the audio chip? Is it a part of the platform or something entirely different? 92HD81B1X does not tell me anything at all.
4. The whole point of Fusion on netbooks was to provide a way of using GPU cores to accelerate certain applications and not to play games. And there are more and more application capable of taking advantage of that. What about testing for example Firefox 4 beta (http://hacks.mozilla.org/2010/09/hardware-accelera... CPU usage numbers when video (flash or h264) is played wouldn't hurt either.

Sorry, but several of your points are not accurate. We do not generally do clean installs on laptops; we uninstall useless programs (you know: McAfee, Norton, TrendMicro, and the various tools that don't do anything other than delay the boot speed and pop up at annoying times). The default install was tested, but probably without the HP Support Assistant active (I find that "tool" rather annoying, just like the Lenovo, Dell, etc. equivalents). It was found to be somewhat noisy compared to other laptops, but I've asked Dustin to check results for temps/noise with CoolSense active.As for the HDD, sure, a WD Black is underwhelming relative to SSDs, but compared to the 160GB and 250GB 5400RPM drives found in most netbooks, I can guarantee it does better. HD Tune is a nice synthetic test of HDD performance, but it's not going to cover everything. Finally, this is our first Fusion laptop, and we're working on reviews of others; I'll take a look at some of the other elements you mention in point four in the future. But I can say that 720p Flash video works fine (I haven't checked 1080p yet).
Dustin will have to respond to the sound comment, but if it's like other laptops I've used I expect it is at best serviceable. Anyway, thanks for the feedback; I wish HP would have put the CoolSense into the BIOS rather than in a separate software tool.

Unfortunately I no longer have the unit on hand as I had to send it back.That said, the sound quality seemed pretty decent but you have to remember these are laptop speakers: if speaker quality isn't explicitly stated it's reasonable to assume it's the same middling laptop audio we've come to know and tolerate.
If other websites are underwhelmed by HDD performance, I honestly don't know what would placate them other than an SSD. As far as mechanical drives go, the Scorpio Black is among the fastest. I actually did do some testing on a clean install of Windows and I was amazed at just how snappy the dm1z actually was.

So the netbook we've been waiting for is too thick, too heavy, and too slow. No thanks. I like the old HP mini's more than this. I rather carry a real notebook at this weight than a half neutered computer.
