Dell DTR Laptop Shootout - M1710 vs. E1705

Power Consumption
For power testing, we removed the battery from the laptop and measured system power draw at the wall outlet using a Kill-A-Watt device. All three laptops were configured to run at maximum performance when plugged into AC power. We tested under stress conditions as with the noise and temperature benchmarks, but we also added a couple more results. First, we have peak power draw, which is often quite a bit higher than the typical average maximum power. We then got a rough estimate of the average power draw under full load, as well as a maximum power draw when only the CPU is placed under full load using two instances of Folding@Home. Finally, we have idle power draw, where the system has been sitting with no applications running for 10 minutes or more. The screensaver is disabled, as is the hard drive sleep mode.
Why would anyone want to get the X1400 in such a laptop? Obviously, because it uses far less power than even the GeForce Go 7800. While 10 to 12 W might not seem like a big deal, that represents 25 to 30% more power draw. Considering that the battery is rated as 80 WHr, a load of 20 Watts will last roughly 4 hours while 30 Watts will only last 2 1/2 hours. That's the theory anyway, so we'll turn to our battery tests to find out exactly how long the systems can run under typical usage.
We also tested power draw with the LCD at maximum brightness and minimum brightness. The total difference was only 6 W, indicating that the LCD manages to be very power efficient. There are eight brightness levels on the LCD, and power draw scales pretty much linearly as you go from level 1 to level 8. The default brightness when running on battery power is 3, although if you use the system in direct sunlight you will definitely need to crank that up. Going with the maximum setting will reduce your battery life somewhat, but you shouldn't lose more than 30 minutes of battery life at worst by setting it at maximum intensity.

The laptop is rather a good laptop except for short battery lifeI would love to order one battery replacement from: DELL Inspiron E1705 Battery http://www.hunt360.net/inspiron-e1705.htm">http://www.hunt360.net/inspiron-e1705.htm

I received my 1705 today. HORRIBLE backlight bleeding from the bottom and left side. Effectively the lower left corner is messed up. There is about a half inch border tapering to both corners on the bottom with the left corner having a similar effect moving up from the bottom.And backlight bleeding is not at all acceptable even if other models exhibit it. Minor bleeding is tolerable, but the one I received looks really bad.

I wish this article came out a month ago - I ordered my video card with the x1400. So far I haven't had any video issues - but the most advanced game I play is Civ4. Can you use the regular ATI Catalyst drivers, or do you need to wait for the Dell issued versions?Is there a FAQ somewhere on the upgrade options for video card/CPU?

A month ago I bought a 1705 with coupon codes from Dealcatcher.com and paid about $1350 to the door. Here are the specs:- 1.83
- x1400
- 1GB 533
- 80GB 7200
- WUGXA
I wish I had waited for this article, because I realize the mistake of not upgrading to a GeForce Go chipset. Memory upgrade to 2GB 667 or a larger 7200 drive and then eBay the spare parts? No problem. However, I thought down the road I could just NewEgg a GeForce upgrade. Apparently, that's not so easy. This laptop is used primarily as a mobile DVD watching/office app/video-pic editing machine. The few games I have loaded are of older engines like Return To Castle Wolfenstein, so I'm not having issues with the x1400 performance whatsoever.
That said, the WUGXA display has issues with reflection (not mentioned in the review). It's like black glass. At night though, especially while on an airplane, watching a movie on such a wuparse resolution is the bomb, especially when others are eyeballing it.
I'm disappointed that the video upgrade is not as easy as expected, but hey, I can always eBay this thing. Besides, as the article mentioned for others, my real gaming systems are desktops. But for portable gaming for those like me who are stuck in hotels on biz trips, these ain't too shabby.
There is no true replacement for desktop power, and IMO, it will be a long time coming before (if) it ever happens. You can only pack so much power in a small package. Portability has it's limitations, as it always has

nice, but even if i was filthy rich i'd still have no use for it in terms of gaming, the only segment i see drooling on this is the one of college students, who typically don't have the luxury of large rooms where they can setup a real desktop solution (7.1 speakers, perhaps a projector, etc). They are also usually eager to get into debt.hardwareguy - Wednesday, May 31, 2006 - link
I don't really understand why you turned off the sound in some game benchmarks. No one in the real world is going to turn off the sound to get better frame rates. I could understand in a sound card test maybe, but not when you're just looking at a video card or laptop.RedStar - Wednesday, May 31, 2006 - link
On the Nvidia site:http://www.nvidia.com/page/go_7800gtx.html">http://www.nvidia.com/page/go_7800gtx.html
you will see that the ramdac is rated the same -- 400MHz NOT 260.
To me that is a serious underclock the same as apple did and got noted for.
Get the latest mobileforce drivers and you can get 366Mhz core optimum.
But with anandtech not even mentioning this and saying there are only 12 pixelpipes..when the reference data would seem to suggest otherwise, i need a definitive answer. I and a whole bunch of others have been trying to get the real deal on this laptop since january :)
What others:
well follow this thread:

As to the person that said gamers who want DTR's is miniscule.... please! :)
Gamers very much do want to switch to laptops --and the latest lappies are starting to make that possible. Why sell gaming DTR versions (with a nice price premium) if there is no market for them? :))

YES DELL has gotten a bad rap for support lately. That's why you buy several years of customer care warranty. You don't have to worry if something goes wrong. Paying for the kind of warranty that used to be free is but a sign of the current times for most companies.

This laptop has the GeForce Go 7800... *NOT* the GTX version. Big difference right there. The Go 7800 GTX packs more pipelines (24/8 pixel/vertex). Also, reporting RAMDAC speed is totally useless: everyone has 400 MHz RAMDACs these days. RAMDACs are used for converting your digital signal into an analog signal for your monitor. What you really want to know is the core clock speeds and RAM clock speeds.Dell could have used faster RAM and increased the core clock, but it would have been at the cost of battery life, heat, power requirements, and possibly stability. Whereas NVIDIA's reference chart indicates that the 7800 Go can have 1100 MHz RAM, the E1705 sets the RAM at 658 MHz. The core? NVIDIA reports 400 MHz and 16 pixel pipelines/6 vertex. Dell runs at 250 MHz, which makes it very slow. You can always try overclocking, of course, voltmodding, etc. If you get the core up to 400 MHz, it would be much better for gaming and possibly would make the 7900 GS less necessary. The GPU RAM speed is still going to be a limiting factor.

i know it is the not the gtx version. Which is why i said the go 7800 and not the go 7800gtx :)from the only stats i could find at the time, i assumed that the go 7800 would be very much like the 7800 GT.
as you can see from the link...the go 7800 is rated at a core of 400 NOT 260!

NVIDIA's rating of 400 MHz does not mean manufacturers have to run it that fast. The thermal spec of a 400 MHz G70 is going to be substantially higher than that of a 250 MHz version. If the laptop capable of handling such a graphics card? Almost certainly, but you would need to upgrade the power brick to the 130 W model if you want to be safe -- the current design already comes close to 90 W peak power draw, and increasing GPU clock speeds by 60% will almost certainly push it over the 90 W mark.
