Battlefield 2 Benchmarks
The final game we'll test in part 1 is Battlefield 2, and like DODS it's fairly CPU limited. While it is entirely possible to run BF2 in widescreen resolutions, there are a couple of issues. First, there's no way to select widescreen resolutions in the GUI, so you have to pass the resolution via command line parameters. Unfortunately, there's no way to adjust aspect ratio in Battlefield 2, so you basically end up with a stretched image. (If you look at what should be a circular map in the top right corner of the screen while playing, you'll find that it's an ellipse, clearly showing that widescreen resolutions are running with the wrong field of view.)
A clear indication that the game is becoming CPU limited can be found in the fact that the sound enabled tests significantly impact performance. FEAR, for example, generally shows little to no performance impact when you turn on sound, because it's almost completely GPU limited. Once again, the audio subsystem in the M1710 appears to be the least demanding of the processor. Note that the laptop was set to 5.1 audio, even though there's no way to connect five speakers, so for now it simply appears to be more efficient. Only the X2 3800+ is able to come out ahead of the M1710, and then only with a faster graphics card.

I personally hate laptop keyboards -- I don't care too much about the gaming aspects, but for more regular typing the cramped space doesn't help me out at all. At least the key positioning is decent, with the home/insert/delete/and/page up/page down keys all having the same arrangement as most desktop keyboards. I wish they would move the Fn key to the top left -- not just on this laptop, but on all laptops. I'm also in complete agreement about the usefulness of a number keypad, and certainly on a laptop of this size, they have ample room to add one.Kougar - Tuesday, April 18, 2006 - link
I thought about that, and I figured there just wasn't room underneath the keyboard to enable a full size keyboard? And there are two air intacts on either side of the keyboard as well.They DO however provide a FN key activated "numpad" over the 789, UIO, JKL and other keys as a sort of compensation, although I found it faster to use the basic number keys in place of it.

I've taken a few laptops apart, and the underside of the keyboard module is always FLAT, save for standoffs. You don't need any room under the keyboard. Unless there's something useful around the keyboard, it can be expanded to the sides.The FN-activated numpad is of little consolation, because all laptops have that feature, even the ones that cost 1/5 that this one costs.
Incidentally.. how the heck do you test a modern desktop system with a Geforce GTX Go, exactly? Take the laptop apart, pry out the PCI-E card and VGA connector, and stick it into a desktop motherboard?

The clock speeds of the GeForce Go 7900 GTX are 500/600 MHz for the core/RAM. I downclocked the desktop graphics card to the same clock speeds, and that's about as close as we can come to doing a direct comparison between the two. It's somewhat interesting to note that there are a few GPU Ltd. benchmarks were the laptop actually comes out ahead by a small margin.3zero2 - Tuesday, April 18, 2006 - link
any comments about fan noise? is it noticable/annoying?Kougar - Tuesday, April 18, 2006 - link
This machine is still identical in chasis to the XPS notebook I picked up late last year, so I'd assume the fans are still the same. On mine they can only be barely heard if you load up a game and play for a bit, but if you play with headphones on you won't hear them anyway.I had a question on the battery life though! How long would this laptop last with just simple internet browsing or Word doc typing, or something similarly light? In performance terms my own notebook wouldn't even make it within the ballpark so I'm curious! Does the Core Duo processor allow you to reach .700 volts at 800mhz as with a Pentium M, for egging out another half hour of battery life for when it's needed?

No, the lowest for Core Duo's are really 1GHz. All the Pentium M generations can reach as low as 6x multiplier so:
Penitium M Banias: 100x6=600MHz
Pentium M Dothan: 133x6=800MHz
Core Duo: 166x6=1GHz
I heard that Intel put a lock on the Core Duo's so you can't lower it from the default lowest, just like AMD did with C&Q on the later revisions.

I'll look at some other areas of battery life in part 2. Needless to say, charging up the battery and then letting it sit 2+ hours at a time doesn't help much with deadlines. LOL I will try to tune the system for better battery life as well. I think the minimum clock speed of the T2600 is 1.0 GHz, but I will need to verify that.Kougar - Tuesday, April 18, 2006 - link
lol! I am very sure it doesn't! I'm certainly in no rush, and I figured part 2 might expand upon the battery tests... I just wanted to provide some extra Qs to answer for it! So maybe I'll toss in another... ;) Does the GPU TDP fit within the previous GO 6800 Ultra/Go 7800 GTX envelope limits? Replacing my 6800 Ultra for a 7900GS and getting better battery life in the process has a certain appeal! Suppose I can keep my desktop 9600XT around just a bit longer instead...And btw, should have said so above! Thanks for the very interesting article on this "notebook"! I appreciate it :) And that tidbit on the Core Duo too!

Audible but not terribly loud. Will have details in part 2.
