Benchmark Results: Battery Life
All three notebooks achieve at least three and a half hours of battery life. However, the HP dm1z stands ahead of the other two Brazos-based systems. Despite using a more powerful APU, it also sports a denser battery pack that allows for a longer battery life.
Charging times are a double-edged sword. Ideally, you want a slow charge so that your battery lasts more than a few hundred charges. Fast charge times keep you away from the wall socket longer, but in the long run cut down on the health of the battery. Manufacturers utilize a variety of charging schemes to strike a balance, which is why we are showing two benchmarks. Usually, the rate of charge starts to slow down somewhere in the 80% to 95% region, which is why the charging time from 0% to 10% is faster than 90% to 100%.
Our “Typical System Use Power” (TSUP) is similar to processor TDP, except that we are measuring power consumption of the entire system under our workload. Remember, this is on the DC side, so it is unlike the power consumption numbers we use in other reviews. This factors out PSU inefficiency.
Interestingly, we see little difference between the 9 W dual-core C-50 and the 18 W single-core E-240. One might expect the NV51B08u and C655D to use more power than the dm1z. The larger 15.6" LCD panels usually correlate with higher power consumption, but it's important to remember that these are LED-based panels. LEDs consume little power, so the difference between 15.6" and 11.6" LCD panels is much less than the difference you would see with CCFL.

one-shot I ordered a Lenovo X120e E350 4GB RAM Win 7 Pro for $529. Lenovo's build quality and matte screen made the deal for me. Personally, I think the DM1Z is hideous.Reply -
hp79 Yeah, I also had a lenovo x120e. Build quality is excellent on those. I wasn't impressed with the performance too much though. It's was little bit slower than my thinkpad x61t core2duo L7500 which was from 4 years ago. But video playback was really smooth. It played 1080p mkv videos with only 30% cpu usage.Reply
Since I got my x120e with e-350 for $305, I eventually sold mine for a small profit.

bobdozer The D525 can only go toe-to-toe with the 3-350 if you only look at the results of multi-threaded benchmarks.Reply
Use the D525 then use the E-350 and you will not go back to the D525 and it will be obvious why. -
juliom Impressive how much bias Tom's has these days... E-350 performs quite a bit better than Atom in pure CPU power and don't even get me started on the GPU performance. All in just ONE chip! As much as it hurts you Tom's, Brazos is a much, much better platform than Atom is.Reply -
They wont put a large battery nor will they price it lower.Know why ,bcos the blue monster has found a new and novel way to continue its monopoly.Reply

I'll admit that is a bit of stinging indictment. :) Can't we play nice? But I understand the sentiment. I really was after the point that the E-350 isn't all that different from the D525/Ion2 combo. It is better in graphics but in terms of CPU it is probably the closest to SU3700. And to be fair, many applications and tasks we preform on a daily basis continue to be multi-threaded.
I completely agree that Brazos is much better than Atom, but I don't think it's one of those automatic game changers, unless you're talking about a netbook. Now if AMD wants to completely and utterly destroy Intel in the the low-end market, I say drop the price another $50 bucks. Price per performance is where AMD historically has had an advantage. Remember X2? But right now, the company is benefiting from Intel having not released a successor to Pine Trail. For the netbook market, Brazos is great, but that isn't what is going to help AMD dominate the market. The lack of products in the mainstream mobile space is why AMD fired Dirk Meyer.
On a side note, I'm a hardware agnostic. That's the way it should always be. I believe in competition and Brazos is delivering it. I just want AMD to bring a bigger fight to the table. They talked so much about Fusion, it's time to deliver. At the moment, I tend to cringe every time Gartner or IDC talks to me about market share.
I think part of the disappointment is that AMD promised me an epic gunfight and I'm watching two people duke it out with peashooters. Ooo so Ion2 does 9 fps Brazos does 12 fps.
