Yup, price is a bad indicator of performance when it comes to AMD, specifically since they're usually more inclined to start price wars than Intel.
Think about it, guys. When is the last time AMD priced itself at a lower or equal performance/$ ratio to Intel when introducing a new product?
The problem is that they can compete only on price, since they are clearly inferior in absolute performance.
That would be Sledgehammer, back when AMD held the performance crown and were almost unthreatened by Intel in that respect. Which disproves your point if anything.Yup, price is a bad indicator of performance when it comes to AMD, specifically since they're usually more inclined to start price wars than Intel.

The i5-2400 is $189. Probably more than the cheapest 8 core BD will end up being if its that bad. The bar could be set at i5-2300 at $179.

What?
That's what he meant.
It isn't a factual statement so it is a purely opinionated statement. In absolute performance Bulldozer wins
Sandy Bridge 12 ALU ops/12 Mem ops vs Bulldozer 16 ALU ops/16 Mem ops
Sandy Bridge 12 x 128bit int/fp Bulldozer 8x128bit fp 8x128 int
Absolute = Paper Performance
and Bulldozer simply out performs quite significantly on absolute paper specs

It's more than probably true at this point. I think only AMD fanboys are excited now regarding BD being great as an all-around performer. I've told people at many times: there's a reason why they're pricing an Eight-Core CPU against a Quad-Core, and it's not a good one.
They'll charge as much as they can for it. They need high ASP.
I'm going to go out on a limb here and say that there is next to no chance that 2600k is going to be beat.

The same as always AMD has a track record for selling high clock/high performance CPUs that are either on par or much cheaper than the Intel counterparts @ price
For some years AMD has priced their CPUs based on multi-threaded performance. This time I expect it to be no different. The Phenom II X6 1090T competed with the Core i7-860 and was overall faster in multi-threaded applications, but lost in single-threaded. AMD priced it at $10 more than the 860 at $295. The 1090T is overall the same speed as the i5-2400 in multi-threaded, so they price it $20 lower to make up for its big deficit in single-threaded.
AMD prices their CPUs based on their performance, most of the time in multi-threaded. You can see this looking at the Core 2 Quad Q9400 vs Phenom II X4 940 and Core i7-860 vs Phenom II X6 1090T. Other times they have failed; for example, the Phenom 9850/9950 vs the Core 2 Quad Q6600, where the Phenom was $20 more expensive and a bit slower in everything.

Absolutely wrong.
Even looking back at the Pentium 4 vs Athlon 64, the Pentium 4 made up for its huge deficiency in IPC with extremely high clock speeds and was priced competitively.
Its big problem was energy efficiency.
AMD won't be able to get a lot more frequency headroom than Sandy Bridge, as seeing from their overclocking event they should only OC 300-500MHz higher on average.
Single threaded performance usually only uses 1 IPC from both mem and alu well Bulldozer has 2 of each per coreThat won't make up for single-threaded performance deficiencies.
Despite this I may buy a bulldozer chip just because it will work with my AM3 motherboard with a bios update. It all depends on how they perform...
:whiste:
The lack of IPC was from a bad design
Bulldozer in comparison is a great design
From bad design
1.53x "nominal" stock frequencies on "normal" cooling
1.83x "nominal" stock frequencies on "exotic" cooling + cherry picked CPUs w/o cherry picked CPUs 1.65x
Exotic cooling doesn't include Dice, LN2, LHe
These are on average or the mean clock rates of various overclocks
3.6GHz 1.53x = 5.5GHz mean average
3.6GHz 1.83x = 6.58GHz mean average

At least Intel could make up for their lower IPC deficit with the Pentium 4 by having much higher frequency headroom.
The Pentium 4's problem was never not being competitive in performance, but rather in efficiency.
Which is why AMD needs twice the cores to be competitive with Intel, correct?
Bulldozer does not enjoy that benefit, and putting more weak cores on a CPU is not the answer for most desktop workloads.
...and yet AMD needs 8 cores and higher clock speeds to compete with a quad-core 2500K
Please explain.
Higher Clock speeds might be do from the lack of ALUs and AGUs
(Bulldozer if compared to SB it is missing 1 Add ALU and 1 Store AGU per core)
Other than that it should perform better than the i7 2600K
Can I quote you on that when Bulldozer gets destroyed by a 2600K upon release?
Can I quote you on this if the i7 2700K/i7 3820 gets annihilated by the FX-8150/FX-8120 upon release?
Remember I only use benchmarks that are open-sourced and compiled by an open compiler or by a microsoft compiler
But, I'm not buying Zambezi, I'm waiting for Vishera(If that is the name)
You will be 'chasing the dragon'. AMD's motto these days is 'wait for the NEXT CPU, it will really be good!' It's not, and then repeat...![]()
Well, the future IS fusion, after all, not sure why any of us are supposed to be wasting our time buying these faux-future chips in the first place.
Mainstream is fusion but Enthusiast will always be non fusion based
If fusion fails to deliver on its promises of OpenCL enabled apps which will be GPGPU assisted then I agree because that will mean fusion turned out to be nothing more than pedestrian on-die IGP.
