Dell Studio 14z Application Performance
You can read about our testing setup and the other laptops used in our previous MSI X610 review. The Studio 14z is more expensive than the Gateway NV52 and NV58, MSI X610, and pretty much any netbook out there. However, it has more in common with such laptops than it does with higher performance notebooks so we will compare the 14z with those systems. Here's the tested configuration of the Studio 14z.
| Dell Studio 14z Test System | |
| Processor | Intel Core 2 Duo P8600 (2.40GHz, 45nm, 3MB shared L2, 1066FSB) |
| Memory | 1GB Onboard plus 1x2048MB Hyundai PC3-8500 @ DDR3-1066 7-7-7-20 (Hyundai Electronics HMT125S6BFR8C-G7) |
| Graphics | Integrated GeForce 9400M Driver version 179.62 16 SPs; 450/1100 Core/Shader Clocks |
| Display | 14.0" Glossy LED Backlit WXGA (1366x768) Seiko Epson D229J 140AT |
| Hard Drive | WD Scorpio Blue 320GB 5400RPM 8MB (WD3200BEVT-75ZCT) |
| Optical Drive | N/A |
| Battery | 8-Cell 14.8V, 4.84Ah, 71.63Wh |
| Operating System | Windows Vista Home Premium 64-bit |
| Price | Price as configured: $1019 (with $159 instant rebate) |
We will start our performance comparison with general application testing, including PCMark, CINEBENCH, and video encoding tests. As usual, we will include detailed PCMark05/PCMark Vantage results where applicable so you can see the individual test scores.

And what should come as no surprise, the Dell Studio 14z places at the top of all of our application benchmarks. Our test system includes a Core 2 Duo P8600, which is faster than any of the other laptop processors. That alone is enough to account for the above charts. Obviously, the 14z isn't going to be able to compete with faster notebooks in terms of raw performance, but it doesn't need to. It provides plenty of performance and as we will see shortly, it still offers good battery life and you get a lightweight chassis.

I don't know where I got 4.6 pounds either....my bad. However, that's still with the 6 cell battery and no optical drive. You say your machine is 4.6 with the 8 cell battery, which puts it about 2 ounces lighter than the 4.7 pound MB with it's built-in optical drive and 50% more run-time.Not pulling the comparision out of my ass, those are the closest configurations you can buy. Even using your comparison, machines, MB w/2GB RAM, 250GB 5400 RPM drive, optical drive, Wi-Fi N, Bluetooth, and 1 year wty, vs 14z with 3GB, P8600, 250GB 5400 RPM drive, optical drive, 8 cell battery, Wi-Fi N, Bluetooth, Win7, and 1 year warranty, the MB is $999, and the Dell 14z is $1079. Not everyone can get the student discount, some people (most people) actually pay around retail.
Even if you're not going to carry the optical drive with you, you still need an external optical drive for loading software and/or burning disks (e.g. backup), so comparing price without it is only valid if you already have a compatible external optical drive.
I used a 3 year warranty because that's what most people I know buy when they buy a laptop. In any case, adding the 3 year warranty works in favor of the Dell because their 3 year warranty is $60 less than Apple's 3 year warranty.
I didn't mean Vista, I meant Windows 7. sometimes my fingers type what they're used to typing, not what I'm thinking. I would never recommend Vista to anyone, for any reason. Win 7 looks promising.

I would have to see hard proof of 50% more run time. Otherwise, it's just pulled out of your ass again.gstrickler - Thursday, October 22, 2009 - link
Go read some of Anand and Jarrod's older articles. They've compared run times with MB/MBP machines a number of times, in each case, the Macs get significantly better run times than the same or similar machine running Windows. Jarrod even mentioned that in the article.Here's a test with an older MB with the 45Wh battery.

3:15 minutes of very heavy (playing 2 XviD videos + wireless browsing + constant downloading) use, 5 hours of wireless web browsing. Multiply those by 1.33 for moving up to the 60Wh battery and you have 4:20 heavy use, 6:40 wireless web browsing. Compare that to the Dell at 3:40 internet browsing, and 3:30 video playback (single XviD only, not XviD + browsing + downloading) using the 74Wh 8 cell battery (from this article). I'd say that's at least 50% any way you look at it. And that MB had a faster CPU and used DDR2 DRAM, both of which will use more power than the new MB, so it may do even better.
Any more "hard proof" you need?

It would also have to be on Windows 7 to be "hard proof," by the way.JarredWalton - Friday, October 23, 2009 - link
We can't provide exact figures right now on the latest MacBooks, but we should have something in the not-too-distant future. Anand handles the Mac side of things, while I do most of the Windows laptops/netbooks. However, I can say with certainty that the latest MacBooks with a 60Wh battery are going to have better run times than the 14z. Priced at $1000, it's not even a big difference in price for what you get.The only real question is whether you are willing to make a switch to OS X. Personally, I'm not willing to switch - I'm stubborn/happy with Windows. Windows 7 also will help on battery life, but it's not going to make more than a ~10% difference (and that's compared to Vista) http://www.anandtech.com/mobile/showdoc.aspx?i=364...">based on my testing.
The fact that Apple has full control over the OS and hardware is a huge benefit; word is they play with voltages more than normal, but I don't know for sure. It may simply be that OS X is very good at entering the deepest CPU sleep states and staying there as long as possible.
Taking "best case", 14z with Win7 would get 253 minutes of Internet surfing (that's giving it a 15% boost, which I'd say is more than it will actually achieve). So with a 71.6Wh battery (Dell says 74Wh on the cover, but they also say 14.8V and 4.84Ah, which means 71.632Hw) the 14z could get 3.532 minutes per Wh.
Taking the worst case on the MacBook, we achieved 186 minutes with a 45Wh battery on the older model. Boost battery capacity by 33% and you would get 248 minutes. Again, that's in a much heavier workload (download + Xvid + web). So in that worst-case test the MacBook should get 4.133 minutes per Wh -- about 17% better than the 14z.
I just don't see any way for the gap to be smaller than 17% relative battery life, and more likely than not it will be 30% or more with comparable usage. Anand has my test scripts for Internet usage, and when he gets the latest MacBook (and time) we'll have the exact figures. In the meantime, I think I'll work on installing Win7 on the 14z and rerunning a few tests as well.
PS: All the above said, I'd still take the 14z over the MacBook. Call it user bias, but as much as I like the Apple hardware and designs, I'm just not a big fan of changing OSes. I've played with Linux as well, and while I can function I'm far more at home in Windows. Been using DOS since version 3 (yeah, I remember how much better 3.3 was compared to the original 3.0!), and despite the quirks I just find it easier to get the tools/drivers/games I need on Windows.

That's not hard proof, that's conjecture. Run the test with the 14z and the mac to compare them, then I will believe you.JarredWalton - Thursday, October 22, 2009 - link
No need for an external optical drive for installing software if you have a network. I install all my stuff over Gigabit Ethernet and it works great. Or from an external USB HDD. I personally don't need an ODD unless I want to play a game or watch a non-ripped DVD. Both are not particularly common tasks for me on something like the 14z (or MacBook). Given the choice, I'd still rather have an ODD, but it's not a huge issue.Pricing for MB and 14z is quite comparable, with the difference being design and a few hardware options, plus the OS difference. I'm far more at home in Windows, though, so I'd pay the extra money to avoid the OS switch... and installing Win7 or Vista on a MacBook is pointless to me; you but a Mac for the OS, don't you?
Anyway, my 2 cents. :)

If you have a second machine that has an optical drive and a network (which is probably most of the readers on here), then, you may be fine without the optical drive. However, that is not true of most buyers. 80% or more of the buyers will need the optical drive.Like you and Jimmy, I don't often use the optical drive, mostly for installing software or converting my CDs to 256-bit AAC. I would prefer to have a laptop with room for two internal HDD/SSD and have a lightweight external optical drive that I can leave home/in my car. Taking half a pound off of what I regularly carry would definitely be welcome. It's not a huge difference, but I think I would prefer that configuration.
You're right, the pricing is comparable, which is all I've been pointing out in my posts. Jimmy (and others, but not in this thread) keeps asserting that "you're paying extra for Mac OS X" with the Mac, and that simply is not true. In some configurations the Dell is cheaper, in some the MB is cheaper, but there is no "Apple tax" or "premium" for getting the MB vs the Studio 14z.
In general, you should not buy a Mac to run Windows. While Intel based Macs run Windows very well, they're not intended to be "just another Windows machine". If Windows is your preferred OS, or if you have Windows only software that you need to run more than about 30% of the time, you should probably buy a machine designed to run Windows. The exceptions to that are when you have any Mac only software (or software that has a significantly better Mac version) that you need to use, or if you simply prefer Apple's hardware and attention to detail.

I agree with you Jared. I haven't used an optical drive in years. I fail to see the point of carrying it around with my laptop to class.JarredWalton - Tuesday, October 20, 2009 - link
Sorry... it was just a guess based on past MacBook pricing.
