Laptop CPU: 2.6GHz Dual vs 2.0GHz Triple?

post #1 of 7
Thread Starter 
Phenom II P650 Dual Core @ 2.6GHz
or
Phenom II P860 Triple Core @ 2.0 GHz

Which should I pick for a laptop? I will be mostly doing word processing, movies, light steam gaming, and virus scans.
I've been looking at benchmarks for hours and it seems to be a close trade off. But none of the benchmarks seems to deal with day-to-day normal use like using regular programs, browsing, etc

Both have official estimated TDP of 25w...I can't find any data on the actual power consumption, or its idle power consumption. I prefer to have lower power consumption of course...I've looked at benchmarks for desktop cpus and it seems at idle, dual, triple, and sometimes even quad CPUs have the same exact idle power consumption.

Laptop specs:
550v/4650m GPU
4gb DDR3 RAM
5400rpm HDD

I'm buying used so I can get the dual for $20 and the triple for $30-35. I'll be installing the CPU myself.

Any suggestions on slow triple vs faster dual? I read somewhere that there is a certain point where GHz no longer matters as much and it's the # of cores that matters. But I assume that's near a high GHz point?

So what would be a good trade off here?

The types of programs you mentioned are almost always optimized for single-thread performance, and will not benefit from more than two cores. Honestly, any Phenom II of any speed can easily handle the tasks you're talking about doing, whether it is two, three, four, or six cores. But for this specific application, I think I'd rather have two cores at 2.6 GHz than three at 2.0 GHz each, because most of the time, I'm going to be running on one or two cores anyway, and the X3 wouldn't get a chance to show what it can do.

Now, if I were doing rendering, video editing, or playing BF3, the triple-core would be the better choice.

Thanks.
Would the Dual Core 2.6GHz be enough if I want to browse the net, run multiple apps - while running a virus scan in the background?

If you have enough RAM, it should be fine. RAM is cheap right now, so there's no reason not to get all it can take.
