Dell XPS M1730: SLI, Penryn, and Overclocking

Overclocking Application Performance
Besides gaming tests, we also wanted to run some more traditional benchmarks. Many of these depend more on CPU and system performance rather than purely on the graphics cards, so this will give us a chance to see how the X9000 scales with overclocking when the GPU isn't a factor. We have used some of these tests in the past, but with new versions of QuickTime and DivX we have opted to start fresh.
Note: All of the application tests were performed with the 167.55 drivers.
We see much better scaling with the CPU overclock in these tests, likely in part because the GPUs are not contributing to overall system load. The CINEBENCH single core result scales almost perfectly with clock speed, while the other three tests get about 80% of the potential speedup. If you want a fast laptop to do this sort of work, the M1730 will work very well. On the other hand, these types of applications also benefit greatly from multi-core CPUs, making quad-core more attractive. It may be quite some time before we see any official mobile quad-core CPUs; in the meantime, there are some notebooks that use desktop CPUs, including the Q6600 and its ilk. Whether you actually want to go that route rather than simply staying with desktops is a tough call; we've never been particularly fond of running a desktop CPU in a laptop, ever since the days of the "mobile" Pentium 4.

If folks are going to be told that a laptop performs extremely well, I think it would be fair to throw at least a single desktop system (mainstream enthusiast level, nothing over the top) into the charts for comparisons. I realize it could stunt the graphs a bit, but folks really need to understand what they are buying into with these machines, and all too often they think they are getting something that is 90% of a desktop's power, and that's rarely the case.If it breaks the grapsh too badly, throw a couple of graphs in the end of the article (much like you have a couple of pages dedicated to "overclocking performance") that give the fair comparison. I'm not saying that lappies aren't worth it, just people should be fully aware of what they are paying for.

I would completely agree with you up until the conclusion of the article. I have never owned a laptop, and probably won't for quite some time. Because of this I don't follow the laptop-only parts (CPU/GPU/RAM/etc.) much and so thought, "This is a crazy fast laptop but I wonder how it compares to a Q6600 with 8800GTX".The conclusion really put the laptop in perspective for me. Basically its a top of the line desktop system from a year ago. That's all I needed to hear. I think it is quite a feat to have a laptop capable of performance a year behind current tech. Yes it is more desktop in a small form factor, but it is a easily portable computer that behaves like a very capable desktop system.
With all that said, I can't wait to build my new system after 3 years with my current un-upgraded one. Just waiting on the 45nm quads and the new 9800's to pull the trigger...

man they got the best job in the whole world do u keep all hardware u test here ,man that is one mean laptop would kill to have it lolPlasmaBomb - Monday, March 3, 2008 - link
Nope, they have to give it back :(Baked - Thursday, February 28, 2008 - link
This is totally necessary... You can probably murder somebody w/ the power brick if they try to take the "notebook" from you.PlasmaBomb - Thursday, February 28, 2008 - link
What size and rating does the power brick on this beast have?JarredWalton - Thursday, February 28, 2008 - link
It's the biggest power brick I've seen to date, rated at 230W output. So assuming ~80% efficiency, even at the maximum load with overclocking it still has some remaining capacity. Heck, the power brick probably weighs as much as a Mac Air! ;)PlasmaBomb - Saturday, March 1, 2008 - link
Cheers for the info, any chance of a piccy?It must get rather hot, if indeed it's 80% efficient it is dumping 50W when drawing 260W from the plug!

Image added. And it could be less than 80% efficient, but the point is the laptop uses nearly as much power as an entry level desktop with discrete graphics.Direct link to image:

Cheers for the pics, good job btw :)
