I would hope not, but what do I know, I only have half a brain.

Also, the BD die is smaller than Thuban, and much smaller than Cayman.
Sorry, it's not irrelevant. 100W more per hour of folding is a hefty increase in a power bill.

how many of those transistors are related to power state control or even added instruction sets or something else that isnt shown in die shots ???


+ hypertransport link and all .... its a big chip and doesnt suck so bad since its a new process + new arch ... but it does suck in the performance dept

You've completely missed the point. Power consumption is an aspect of performance, and consuming 100W more per hour is a performance failure. Now giving an excuse that it's fine because it has 500 gazillion transistors is what is irking me. As an end user you should care about the end, not the means.

See above - I already have a 2500k.

Let's put it this way -

Processor 1 - 2billion transistors
Processor 2 - 1billion transistors

They perform equally and consume exactly the same amount of power. Which is better? Neither, they are the SAME to the end user.

I don't know... I still think AMD is hiding something in that chip. There's a first for everything; P67 had SATA problems, BD has high power draw. A revision should hopefully fix those drawbacks

This shows that BD scales with clock speed. This architecture has hope if they can fix the poor single threaded performance. Or even if they dont fix the threaded performance if they can get the default clocks higher it will be decent.

I was actually trying to pull some numbers out of this to compare the linearity at which the processors scale with clock speed. At the stock settings, and all cores loaded (Cinebench or something like that) what clock would BD be running at? Or does load fluctuate enough where it would hit different levels of Turbo? I would also prefer a benchmark that we know scales as linearly as possible with clock speed/cores in order to remove that variable. This might give us a good idea how much headroom there might be with this architecture and future revisions - if it's linear up to the max overclock, we may have a better outlook for the future.

the "Bulldozer" architecture on which the FX chips are based is a "speed demon"—a CPU designed to run naturally at high clock frequencies. The concept is to do relatively less work per clock cycle and to enable higher speeds to make up the difference.

I must say, those problems are very related .
