I am not one of those amd users who thinks everything should cost $100. I too expect the the 8 core to be over $250

Let's hope AMD pulls out a Win for the Enthusiasts sake, cuz pricing at $300 will be a complete failure at that point.
What I meant was core vs core. A 8 core Bd will be faster than a nehalem cpu if it matches the performance core wise.

His point was that if the chip is only able to match Nehalem's speed, then $250 is simply too much. Better off with a 2500k which will be a faster machine.

Now, if each core is as fast as a Nehalem core and they're throwing 8 at us, then fine, $250 is really reasonable and I'll be jumping all over this.

Here's to hoping for each single BD core to be as good as a single Nehalem core. The 990x still outpaces the 2600k for multi threaded apps quite handily even with lower clocks (5ghz is common on the 2600k while the 990x sits more around 4.2ghz) which would mean that a Bulldozer with 2 more cores even than the 990 and probably better OCing capabilities will truly style all over Sandy Bridge for high end applications.

Look at it this way.

2500k: 100 + 95 + 90 + 85 = 370
2600k: 65 + 62.5 + 60 + 57.5 + 55 + 52.5 + 50 + 47.5 = 450

So it is a pretty noticeable difference, around ~30%...

BUT

-2500k overclocks to ~5 GHz on average. 370 * 5 = 1850
-2600k overclocks a bit differently depending on batch (more so than other chips is what I mean, I know that applies for all chips), but for comparison's sake let's just say average is ~4.6 GHz with HT on. 450 * 4.6 = 2070

So the final difference is MUCH less. Not worth $100.

Hmm... Do you think intel will reduce prices $50 / £50? when BD is released?

Would be a great tactic and makes sense if IB is gonna be out sometime next year.

Rumor has it they will. I expect a 4 GHz+ Core i7 to take the price point of the 2600k.

Um, no. Look at it this way.

2500k: 100 + 95 + 90 + 85 = 370
2600k: 65 + 62.5 + 60 + 57.5 + 55 + 52.5 + 50 + 47.5 = 450

So it is a pretty noticeable difference, around ~30%...

BUT

-2500k overclocks to ~5 GHz on average. 370 * 5 = 1850
-2600k overclocks a bit differently depending on batch (more so than other chips is what I mean, I know that applies for all chips), but for comparison's sake let's just say average is ~4.6 GHz with HT on. 450 * 4.6 = 2070

So the final difference is MUCH less. Not worth $100.
Thanks I had it wrong...
