PhII and C2Q/C2D are for the most part, clock for clock equivelent. Core i7 has notably higher IPC (along with i3/i5/etc), SB is a bit more IPC and a lot more OC headroom.
That said, there are huge differences when you get down to models (2core vs. 4core, etc), as cache/turbo/bus/etc all come into play. For example, an overclocked PhII X6BE will outrun a stock i5 or i7 in many things, but that doesn't mean that it's a good value or better at everything.
A better question to ask is :
"My budget is X, I have X components already (if any), I want to do X, Y, and Z, what is the best buy?"

"Half-Life 2 = Over Rated."
I shouldn't even reply with you having that in your sig but I will because I'm a nice guy.
It really depends on the application. If you're mainly looking to game at high resolutions then going from a cheap AMD quad to an expensive Intel i7 quad really isn't going to do much for you. If you're all about crunching numbers that's a different story.
So, what's the budget and intended application(s)?

Need a new laptop after old one died from being dropped in a puddle. Borrowed a Pentium M from the office but it's slow. I was thinking about getting a quad core Amd for 500$(refurb).
Or I can drop another grand for a brand new sandy bridge laptop. Either way I need something for light gaming + number crunching.

I was browsing laptops at Costco and noticed that there was a Core i3-2310M(Sandy Bridge) laptop. It was at $599. I don't buy the value lines but the price seemed really compelling. If you look around you won't really pay much more for far better hardware specs.
Really sly way to make it look like you are posting in a right thread though.

That s not true, PhII is superior to a C2.
No need to overclock a X6 to outrun a I5 2500 for tasks for wich
thread count is important..

Got a link? I tend to avoid dell, hp, acer and all the other shit brands.
Nope.
Wrong again. IPC will always matter. Doesn't matter how many cores you add because the competition can always add more.

Nope, as I said I was looking in store. So next time you are at Costco shopping for groceries, check the laptops there out. I don't remember what the brand is because I don't care unless I'm going to buy one. But the companies you listed are about half of what's out in the wild, so good luck.
Lol...Thanks to as much as 5 sysmark Bbenches , C2 manage a global tie.
You should be the first to know that bapco benches are biaised...

Hmmm...the guy has 5 posts...all of them praising AMD processors in one way or another...
http://forums.anandtech.com/search.php?searchid=782355
We re talking about two existing processors, not hypothetical
counter measures...
When tasks are heavily multithreaded , an X6 is no worse
than a 2500 while the 2600 doesn t show large superiority.
Seems that you didn t read the link s content ; and instead
you re getting off topic to undermine one s arguments.
The figures presented in the said site are quite evidence
that sysmark is all but unpartial.
What is the use of removing 8 filters on photoshop bench
to retain only a few and then run them several times as part
of the overall score.?...
One would expect that to show a processor s versality, tasks
must be diversified, but here, it s the contrary that happens...
As for my posts favouring AMD, it s about the discussed points.
There are also AMD things with wich i don t agree at all,
perhaps there will be a thread where i can point their lackings...

Nice try, and you are starting to sound like a troll. Look close again. Why do I even bother, reality is in the eyes of the beholder.

Clock for clock:
PhII vs Conroe/Kentsfield - Intel's a small bit faster (let's say equal)
http://www.anandtech.com/bench/Product/97?vs=59 (AMD has a 100MHz advantage)
http://www.anandtech.com/bench/Product/85?vs=53 (AMD has a 200MHz advantage)
PhII vs Wolfdale/Penryn - Intel ~5-10% faster
http://www.anandtech.com/bench/Product/97?vs=56
http://www.anandtech.com/bench/Product/81?vs=50
PhII vs Lynnfield - Intel ~25-30% faster
http://www.anandtech.com/bench/Product/97?vs=56
PhII vs Sandy Bridge - Intel ~30-45% faster
http://www.anandtech.com/bench/Product/102?vs=288 (AMD has a 100MHz advantage)
So it's not even a contest clock-for-clock. it does look better when comparing CPUs at their price ranges (which IMO is the proper comparison). But still AMD is way behind in performance. The X6s don't really change the picture much either.

Looking at the first link, almost 25% of the benches (7) are rigged.
Not only sysmark, but also Blender wich curiously works
70% faster withy amd proc. when using linux compared to windows os.
Winrar is so intel friendly that many sites don t use it anymore
and prefer 7zip, as done by Techreport...
All in all, the C2 need quite a big help from selected benches
to keep pace with the PH2, nevermind the Ph2 100mhz
advantage wich is 3% frequency wise and surely quite
less in applications....

5 posts are not a significative statistical sample that would allow
to draw a conclusion..
By contrast, i can see here people with hundreds if not thousands of posts all praising Intel whenever a processor discussion is on the way...
I am not going to support someone that seems to be a bit blinded. But there is a point lost and you just brushed it away with the catch phrase that people use to sound smart. In terms of core design I agree that IPC should be a priority. But that doesn't mean that core count should be disregarded and in situations that where thread count and multithreading is highly used the PIIX6 is really strong. Not strong enough to make up for 4 cores with 20%-30% advantage in IPC, but the Phenom II's weakness has more to do with the lack of core speed to go with the the lower IPC design.

Eh? Aside from Netburst and the recent northbridge issue, Intel deserves a hell of a lot of praise. I'm all for Bulldozer being a Handbrake monster, and I believe nVidia licensing SLI to the 990 chipset may say something about it's performance. That said, until I see this new FX series in the buff, AMD is NIMBY.

In the third link given above, the PH2 win 17 benches out of 30,
despite the rigged sysmarks that are FIVE benches and very
opportunly put at the top of the page...
Yet, the guy assume it as a prove of PENRYN superiority...
So one may ask what blind really means for you as well..
I could also add that PH2 get optimisation only in cinebench
starting with 11.5.
For the latter bench , here the corresponding comparisons :
First, Anandtech for cineb.10
http://www.anandtech.com/show/4083/...core-i7-2600k-i5-2500k-core-i3-2100-tested/17
Then Techreport for cineb.11.5
http://techreport.com/articles.x/20486/12b.
Was Anand use of cineb.10 rather than the recent 11.5
a calculated move ?..
One has to wonder, since when testing brand new processors, one
should use the latest versions that are likely to be better
optimized whatever the processor..(unlike it is bapco , of course)....

I'm not calling him a nutjob. I'm calling the guy who runs van's hardware a nutjob.
Reading some of the guys articles on vans hardware, I get the impression that he is a nutjob who believes in some great overarching conspiracy to justify why X is X and Y is Y.
Just like those doomsday cultists and the 7-day adventists, jehovaw's witnesses, and those baptists that spread the world will end fliers trying to get you to join them to 'save your soul.'

So you're saying that it doesn't matter what a cpu's IPC is? Wrong.
Wrong again. I had an i7 720QM laptop. It was much faster than my phenom desktop. Especially in cpu intensive tasks the i7 at 1.6ghz(+Turbo) would match the phenom at 3ghz.
What the fuck are you talking about? You're the one who comes in with a biased opinion about how great amd is, and how evil intel is.

^^ This Abwx character is obviously some kind of zealot. I happily run a 955BE, which replaced a PhII 805, and it's a decent chip. For practical purposes, PhII and C2D/C2Q are core for core roughly equal. There are so many different C2D-based chips out there with so many different cache configurations and bus speeds that it's probably better to just analyze individual matchups rather than try to find a blanket statement.
PhII and C2Q are functionally obsolete for new builds, so it's kind of moot anyway. Perhaps Bulldozer will shape up to something decent, or might just come out of the gate being amazing. I tend to not pay much attention until final silicon is in the hands of trusted reviewers though. Speaking of trusted reviewers, lol @ Abwx saying portions of the Anandtech review above were 'rigged'.
