Poll, generally YES OR NO

T2400. It sucks. It's only a Duo. Not a Core 2 :(
I thought the Core 2's would be a lot more expensive than they are.. Well, turns out they're not expensive. And they're a lot better than the previous generation. Damnit!
Core 2 Duo here. Will be upgrading to the Core 2 Quad as soon as they come out.
P4 1.8ghz, no,
have no need for such atm, haven't upgraded my pc in years (except for few additional hard drives)

P4 3ghz.. perfectly adequate for what I do, which ain't much. However, when I set up my music studio I'll get a couple of core 2's, or even quads if they're available, exclusively for music production and nothing else.
Is the dual core supposed to be better than P4?
Well first off, the Core 2 Duo is 2 processors on a single die, which is good. However, moreso than that the Core 2 architecture (whether Duo or Solo) is a much better architecture than the P4 in general. Its much more efficient and able to do more work in a clock cycle than the P4s did. Its actually a design that at first glance looks more like an AMD design than an Intel.

It is just a natural progression, I really think breaking 4gb's is going to be very difficult and wont be seen for awhile. Dual core is no substitute for raw clock speed.
Yes they are much better than P4 but also benefit from larger fsb and cache so maybe architecturally very similar....but i could be wrong.

Thank you.
I think you have a few misconceptions. 4gb? I assume you mean 4 GHz and you are correct in that respect, but the thing that you have to realize is that no one is in a rush to break 4 GHz. What we REALLY care about is how much work can we do in a given second. In this respect, clock speed doesn't matter. If I can do more work per cycle than your processor can, then I don't need as high a clock rate. Believe me when I say a great deal of the micro research is towards achieving the greatest IPC you can (instructions per cycle). Intel hit a point where they were doing almost zero work per cycle. They could do a single 32 bit integer add. That is not a lot. Meanwhile, AMD processors we comitting 4-8 instructions and keeping their ALU units busy more often. This lead to a much higher IPC. Intel now though as I commented above has taken this approach (notice that they have stopped using clock speed as a major marketing tool). In addition, most of the bottlenecks of today's performance aren't even related to the CPU speed, they are related to memory speed. Look into something called the "memory wall" to get a bit more info. Architecturally, they are VERY different, this is the reason Intel has pushed the Core 2 architecture even over their Core architecture.
On a much more personal and unscientific basis, I can tell you that the responsiveness of multicore systems is MUCH better, and this alone adds a great deal to the experience of using one.

Yes I meant 4GHz, i read it back and still misssed it:D
The final consideration is what the system will be used for, there are applications and work flow where higher clock speed is more important.
Given all this what would you say is better>

Consider clock speed, fsb and cache.
Wonder what the purpose is of there being 2 cpu's priced so close but designed so different.

i've seen some on ebay. they are advertised as 6.2 e.g. is this how they worl or is it a scam
I dont know what you mean? cpu's have gotten very compicated lately, seem's like the middle of a transition.
Processors were always complicated, Intel marketing just convinced everyone that they could judge the speed of a processor on clock speed alone. It's never been that simple though.

sorry i mean like this

they add both processors to make 6Ghz, is this how it works or is it a scam

Don't upgrade to Intel's Quad-core as it won't be true quad core but rather just two dual cores stuck together. Intel won the dual-core battle, but they're gonna get dominated by AMDs true quad-core (four actual cpus in one rather than two stuck together like Intel).

No, ther'e dual core (1 actual cpu -) and quad core (2 actual cpu's-Xeon). That supposedly has the 3GHz which should be 830 chip as opposed to 805 (2.66) as it is listed.
It is all on Intel's website http://www.intel.com/products/processor/pentium_d/specs.htm
Also, the mainboard is cheap but for the current bid would be good net pc. and some nice blue screens.

home desktop's not dual-core, but is dual-proc. Old sucker, though; circa 2000
the work laptop's a Centrino Duo, though. :D
