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.

first of all, the mini 311 has only an N270the E-350 has more than twice the cpu power (cinebench etc.) and it was a hassle to work with an N270, an E-350 works almost like a normal laptop, office etc. quick and responsive. Multitasking, no problem.
Thats a huge difference and it does so with higher battery life and a lower price.
So what is so special about brazos? It beats hands down everything Intel/Nvidia have to offer right now in this mobile market space and that is a 1st for AMD.
Better performance, geat battery life and great price. Ther is no point in buying an atom anymore.

This even looks just like my HP Mini 311, Infact I bet its the same Chassis at least. I love seeing this ultra-portable market advance but HP really turned me sour and I will steer clear of them forever at any price point.If this machine suffers from the same flaws my Mini 311 did please be warned!
HP refused to service mine in anyway 72 days after warranty despite it basically falling apart. I paid $500 for my Mini 311. To keep yourself from falling into the same boat as me watch out for this:
1) Fan if the fan makes *any* weird noise at all even once, And or it runs continuously have it serviced or at least file a request. My fan started to die in less than a year but I limped along just past my warranty date then it completely died. I can find no replacement for less than an $65...
2) My speakers quit a couple weeks after the warranty, The audio jack works but not the speakers.
3) Check the temp sensor in the Bios, Mine had a bad habit of turning back on, or continuing to run when I thought it was in standby and if I was not diligent it would have overheated inside of backpacks cases etc.
I work in computer repair and I feel like I'm one of the best people to get stiffed with a dying computer as I have a lot of resources to fix it, but even then I feel like I am out almost $500 and HP showed zero signs of desire to help me out.
Unless they make it right I'm going to continue advocating a different brand. I see HP Dv6000's come into my work everyday with similar problems. I think HP is the most repaired/Dead laptops we see. Sony/IBM being the best. This is just a observation.

I forgot to mention, in 15 months my batter life went from 4.5 hours to 20 minutes also...tammlam - Tuesday, February 22, 2011 - link
I bought one of these for my wife and everything was going well for the first 3 weeks until this past weekend. Turned it on and all we got was a bunch of distorted, horizontal lines. The screen periodically went dark as well. Once in a while, it clears up and the screen looks normal but this didn't last long. Now it is waiting to be picked up for repair and hopefully everything will work the way it should.Besides this glitch, it is a very nice notebook and I removed most of the preloaded programs. Got it down to 50 processes.

Once again I am disappointed in HP. I keep WANTING to buy an HP and they keep forgetting to put a HOME and an END key on their netbooks. So I bought an Acer from Costco. Nothing fancy but I can type with it.Dustin Sklavos - Tuesday, February 22, 2011 - link
Fn+Left Arrow is Home, Fn+Right Arrow is End. They're there, they just aren't marked.silverblue - Tuesday, February 22, 2011 - link
...a 2GHz Brazos. :) Unfortunately, I still think that whilst a faster CPU would help, the single-channel memory interface is choking it.swaaye - Tuesday, February 22, 2011 - link
That's a horribly slow subnote, not a netbook.swaaye - Tuesday, February 22, 2011 - link
That's a super slow subnotebook, not a netbook. You could've gotten something like this 2-3 years ago.mino - Tuesday, February 22, 2011 - link
You could have got something like this 4 yrs ago. For $2000+.Game. Set. Match.
