Processor review looks weird without overclocking!

Sandy Bridge is obsolete in one year. Intel has said they have completed the development of Ivy Bridge. Why should we buy Sandy Bridge and the socket, that is changing into a new one in a year? See you in 2012

What do you suggest I get if I need to build a rig today?

Ivy-bridge is going to use LGA 1155 and it going to be compatible with current LGA 1155 motherboards

Maroon1, no, 1156 is succeeded by 1155 for i3 and i5, and the 1366 is succeeded by lga2011 (former lga1365) for i7. The ivy bridge processors will be compatible with sandy bridge motherboards only at these low-level chips.

Sandy bridge E will be on lga2011 though along with Ivy Bridge i7.

Using Intel/AMD 50/50(no fanboyism). What I meant was take price into consideration in conclusion.

I am sick and tired of the complaints of biased AMD fanboys. (All my build are/have been AMD, except my parents' C2D. I am not an Intel fanboy.)
Why use a Phenom in the review and not overclock?

For the same reason that none of the other CPUs (and they overclock better than the Phenom) in the test are overclocked. It is a reference performance review. Xbitlabs does plenty of OC reviews. This one isn't one of them. Beside, why would you even bring overclocking in an article about a CPU that is clearly and explicitly not targeted at overclockers?
...or it should have included Athlon X4 and X2 as this is the competition for i3-2100 currently.

You explained why in the next two sentences:

Athlon X2 250 is 53% cheaper than the Core i3-2100 right now.
Athlon X4 640 is 14% cheaper than the Core i3-2100 right now.

The i3-2100 is not targeted at the Athlons otherwise it would have been priced the same. And what's the point of comparing with these CPUs if even the Phenom can keep up with SNB?
If either Athlon would have been used in the review idle power would have been the same as i3s.

And Zacate would have had even better power consumption. It is irrelevant if the performs is not in the same zip code. Do you imply that we should compare SNB to the best AMD has to offer in each individual test category and not a single CPU across all test?
Why is it a waste for Intel to make inexpensive Quad cores from a customer stand point?

First off, Intel is not a customer, they are the supplier. That out of the way, it is a waste for Intel, because they can compete (performance wise) against Phenom X4 with a 2-core, 4-thread CPU. Using quad core processor would undercut their margins by either reducing sales price of the dual core CPU or eating into i5 sales. The problem is not Intel - they simply maximize their profits, but it is AMD for not been able to compete - Phenom is a dog (remember I have two X4s).
I sure as heck hope the Llano brings some competition to the table. This is the only reason my money have not gone Intel's way yet.

Athlon X2 250 is 53% cheaper than the Core i3-2100 right now.
Athlon X4 640 is 14% cheaper than the Core i3-2100 right now.

So, what is your point ?

Since i3-2100 performed better than Phenom II X 955 in more than half of the benchmarks, it is safe to say that i3-2100 is going be faster than Athlon II X4 640 in most cases as well

Athlon X2 250 can't even touch it.

In other words, you are paying more money for a superior processor.

As for overclocking, most consumers don't overclock their CPU
And if you are an overclocker, then don't buy i3 2100. Problem solved.

Many applications used in SYSmark 2007 for performance evaluation can split the load well only in to parallel threads.

Am I right to think you meant to say "...only into two parallel threads..."? Should I suppose, then, that the quad processors have the potential for much better performance when the software has caught up? If so, when might this happen?

It would have been nice if Xbit were include a Phenom II X2 and an Athlon II X2.

Since this is a review of DUAL-CORE CPUs then I would like to see the i3 compared to competing DUAL-CORE CPUs, even if they are at a different price-point. The X4-955 is at the same-ish price so it is a fair comparison... sorta. It's just that since a lot of the tests are not massively threaded, the quads are at a disadvantage. If you were to compare an Athlon II X2 265 (3.3GHz 2x1MBL2 noL3)or Phenom X2-565 (3.4Ghz 8MBL3) to the X4-955 in the lightly-threaded tasks you wouldn't see much, if any difference.

P.S.: As of this posting @ newegg:
P2x4-955= $140
P2X2-565= $125
P2X2-555(3.2)= $90
A2X2-265= $78
i3-2100= $125
i3-2120+ $150
All prices rounded up by $0.01.
