but, if you are not gaming/video encoding. would the 1645 be any faster than a core 2 duo based XPS 1640 ....everything else being the same? I mean for day to day use, web browsing, word etc.

On battery it - at first - struggled to even get to a 12x multi, but after changing my power plan to High Performance (it was set at the default Dell profile, don't ask me why), it again jumped up towards 2.53Ghz. So double check your power settings.
But don't trust the Intel gadget. On my desktop it sometimes reports ridiculous numbers:
It sometimes even goes as high as 40+ GhzThat's probably to compensate for my 1Mhz XPS 1645
-
I'm going to be using my 1645 which arrives tomorrow, for day to day usage any gaming i'm planning to do would be on my PS3. -
thanks for the info on the C2D vs i7 architecture. Well, I am doing the same ps3 + 1645 solution as you. ps3 for gaming is better because I have noticed that they release more titles on ps3/xbox than on PC. ipod touch for gaming on the go. My 1645 also arrived in two days. I hope that dell issues some bios update soon to fix/reduce the throttling/

But, I guess, it has to be because the 3DMark '06 scores for the i7 are higher than the C2D, so even with throttling it is faster? T9550 scores 2061 @ CPU/3DMark '06 versus i7-720QM scores 2848 @ CPU/3DMark '06 on battery.

but, isn't the i7 running at the regular speed before getting throttled due to gpu + cpu use.That is, for day to day stuff, it should be faster than C2D.

Comparing my SXPS 1640 (T9600) to my SXPS 1645 (i7-720QM), I have not noticed any difference in speed using:
Office 2007
Firefox
iTunes
Listening to music (streaming/CD)
Files are extracted far quicker, though. But, I do that like, what twice a day? I gained maybe 10 seconds, which is a a molecule in an ocean compared to the time I've wasted with this throttling issue, lol!
@fr0x
I was just quoting my own score. The CPU score could be influenced by other things, too, but with my "old" configuration (4GB is only difference, otherwise sig) I got 2848.
~Ibrahim~
EDIT: Post above....this is pretty subjective: case-in-point. And Mitchell, are you sure none of these "faster" attributes could be to your SSD, which is shown to have huge day-to-day performance benefits? -
If not, I think the difference is due to TS
EDIT: Speaking of itune, anyone know if Dell will fix the problem of synchronization of iTunes with the PM55? -
My problem is just that my daily jobs are not normal uses., I'm a software engineer. -
I agreed with you. I have never played any games or watched any movies on my laptop since the screen is just too small for me (Even 16 inch). So I leave those tasks to my Ps3 connected to Samsung 46 FHD LED in my room (I sometimes use it for an external display for my laptop. It's nice )
However, I still need very powerful computers for my software jobs. So, TS + 130W is needed -
-
I know it's a verified problem with PM55 + iTunes, but my brother's and dad's iPhones (3G and 3GS) have synced no problem. But as to your question: no idea.
~Ibrahim~ -
I had been using for 5 days before returning it.
my i7 820QM, 6GB with throttle issue could not handle my daily jobs (running mutiple powerful servers and required-powerful-computer software applications at the same time). It's still slow sometimes. (It might be ok if it could run at full capability)
It's just that bad, in my case -

I find the throttling most noticable when your group is fighting multiple enemies at once.
I was running it at 1920x1080, no AA, everything else on max. Screen was at or below 50% of brightness. -

Click on the third item down on the right:- 'Help me choose a processor'.
You should get a pop-up:-
http://syndication.intel.com/Distri...87110501&contentType=0&cc=GB&campaignId=18649
It should come up on the i7 processor, but if not, select this.
Then hover over 'Extreme Gaming' More Information, i.
That's 'Extreme Gaming', not just 'Gaming'.
Click on 'Learn More', if you like. More about how suitable this CPU is for gaming.
If Dell want to pull these pages, it will be very interesting to see how enthusiastic Intel are about having the i7 downrated in this way. I mean, if you can't game on an i7, then what the hell can you game on? -
So on there site they are simply downgrading or say bringing expectations down a few notch in regards to the laptop being used for extreme gaming knowing the fact that it throttles.
Mine is coming tomorrow and iv decided to keep it rather than return it. -
just curious, what made you decide to keep it rather than returning?
-
But the one factor that made me buy it was the RGBLED screen, its looks and its specs. i mean it does have its flaw but then again so does my GF.lol. -
haha yea not everything is perfect. I think that apart from intensive gaming, even on the 90W charger, the cpu does perform at the normal speed and also does turbo boost when needed(1.6ghz and 2.8 turbo for 720qm). What I learned is that the system works fine for CPU intensive tasks. So, it's NOT like we have bought a 933mhz quad core i7 cpu.
-
I don't know if it should be posted here it's just every one is talking about the RGB screen so here we go, the RGBLED screen is MATT I have removed the clear plastic cover on mine and was very glad to see the matt finish under
so now all I have to do is trim out the clear plastic and keep the edge.

I will take one now I just have my blackberry so hope it looks ok.

Acer has recalled over 22,000 Aspire one notebooks http://www.theregister.co.uk/2010/01/11/acer_recall/
At least we don't have a burning laptop on our hands. -
I don't know if you can see I have put the removed clear plastic over half of the screen not grate I know should be able to tell buy the reflection of the light.

While the glossy screen is in some respects really nice, in others it is quite annoying. If there would be a way to re-finish the rest of the screen, this might be a nice option for me to think about...
But this is getting off-topic. -

I decided to add an extra column to the monitoring section which reads the data coming from the on chip digital thermal sensors. These sensors count down towards zero as the core temperature gets hotter and hotter. It basically tells you how much head room you have before the Intel CPU decides it is running too hot and will start to thermal throttle.
I thought this data would be interesting because it should clearly show that the Dell throttling scheme has nothing to do with how hot your CPU is running. When these laptops start to throttle, they are nowhere near running too hot based on the Intel specification.
If you would rather see the core temperature of your CPU in this column then just go into the ThrottleStop.ini file and add this:
TJMax=100
Set that to whatever the TJMax is for your CPU. You can look in the RealTemp Settings window if you're not sure what this value should be for your CPU.
I also added this new data to the log file and I added another INI file option that keeps track of whether you previously had ThrottleStop enabled or disabled when you last closed it.
Correcting the throttling behavior of these laptops is a top priority in my opinion so I raised the priority of ThrottleStop as high as it can go. ThrottleStop is fairly efficient so hopefully this will help to correct the throttling slow down as soon as possible even when your computer is heavily loaded.
Happy testing. -
I'm beginning to think it's the design of the screen and it won't get fixed! If that's the case i'll need to get it changed to the standard 1080p screen! -
so Dell USA just increased the price of the 1645 i7 from $1649 to $1699 same specs. What are they smoking..
-
-
-
-
Maybe the extra 50 $ is for a 130W Adapter!
-
-
Mine is fine on all settings also

It flickers some times, like they turn of the backlight and then really quickly turn it back on again. -
Where can I find the latest version of TS?
-
http://www.fileden.com/files/2008/3/3/1794507/ThrottleStop.zip
I try to also keep the latest version of ThrottleStop available at the above link.
FileDen craps out once in a while but it's usually pretty good. Version 1.80 awaits. Clear your cache if you get an old version. -
I was wondering why is the highest you can set the multiplier 13? Is that the highest possible multiplier when all threads are being used?
