I just got SXPS 16 with the specs below
i7 820Qm
4GB 500GB 7200
Bluray rom
ATI 4670 1GB
And I plan to buy an imac to be my powerful Desktop or in case my Laptop stops working sometimes.
I need one more powerful than my Dell (If less I dont know why I have to buy a Desktop anyway)
I know i7 2.8Ghz quad core with hyper threading and Ati 4850 512 GB model from new Imac will beat My Dell badly but How about i5 model with ATI 4850 512 or Core 2 3.33 E8600 (if I got it right) with ATI 4670 256 GB?
Can you tell me?

Depends what programs/games you're using...
-
I'm an Software Engineering. I spend a lot of time accessing to many servers and applications at the same time.

Most engineering software should be CPU bound. The sXPS 1645's i7 820QM would most likely beat the middle-high end desktop C2Ds and low-middle end desktop i5s in programs that fully support all cores and threads.
-
I would venture that the i5 iMac with the 750 processor is probably about 20-30% faster than your 820qm XPS. Mostly due to the much higher CPU frequency. 2.6default with turbo mode in the mid 3's. On your 820qm, you'll only see about 2.7Ghz under very light threading, where the 750 will push for cores at 2.8Ghz most of the time, only clocking back to 2.6 under very heavy utilization and/or high temps.
The 860 wipes the floor with the current laptop CPU offerings. I would pay the $200 upgrade fee for hyperthreading, the increase in default clock speed (2.87 which is actually 2.93 under most fully threaded loads), and turbos to 3.47ghz. -
So even Core 2 duo 3.33ghz still beat my i7 820Qm? What you would pay for 200 bucks. I lost here. -
Hyperthreading is overratted. Few programs out there will take advantage of it. You'll know if your program takes advantage of it.

Actually I don't think he's a troll. He's posted the same kind of question in the Apple forum. I was checking his history when I stumbled across this thread. Perhaps he's after the iMac's form factor? I think if he's looking for a powerful desktop to run Windows he should forgo the iMac and get a PC.

Yes I need to pick imac for the following reasons
First, I 'm planning on building SW application for Iphone.
Second imac is the only all- in -one PC offering powerful processor enough my needs. I have a limited space for my desk.
Third, I might move to work for Apple in the future . I think it 's possible since I'm just 29 years old. So I better learn about apple Software and product
Hope You understand
Thanks -

There are probably some situations where the C2D will match the nehalem chips because of the fast clocks, but in general the nehalems are more powerful.
The 860 is not just about hyperthreading. It has a has bit higher default clock, and even more aggressive turbo capability in addition to hyperthreading. -

It depends on what applications, it will be faster in programs that support the full 4 cores and 8 threads.
Xps 16 can beat Which model of new Apple Imac
