The power draw is outlandish given the performance that you get in return and the price that they're asking for these.

@4.7Ghz, your still getting outperformed by an X6(at 4.2) which is pretty good for rendering, matching the Bloomfield quads. The X6 can be had for $150 brand new...

At stock settings, a 2600k only consumes 65w, half of Zambezi.

Ofc he hasn't seen a 125W 1055T overclocked to 4.2GHz and benchmarking...

Mine goes beyond safe temps, even when running all alone on the triple rad, Ultra Kaze 3000RPM @fullspeed with an EK Supreme HF with the second most restrictive jetplate.


That is A HELL LOT OF POWER CONSUMPTION.


But once again, seems like BD is the only power hungry processor here.


No one remembers P4 Prescott Extreme Edition... At 3.8GHz they ate twice the power as the FX-57... And ran even slower

Power isnt that bad for 2 billion transistors. It would be inline with SB probably better if they could cut it to 900 million like SB. I dont see them being able to drop the power envelope with 2 billion transistors. BD seems to love high clock speeds but the leakage on 2 billion transistors is taking its toll, the architecture right now is a conundrum.

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.
I never said that transistor count was relevant to the end user. You formed that conclusion yourself.

Why are you picking a fight over my pointing out of an obvious fact about the Bulldozer architecture?

Also, Cayman die size is 380mm on 40nm. Bulldozer is 315mm on 32nm, not that much smaller with the node difference taken into account.

It's irrelevent. A similar incident by Intel in the past does not excuse AMD now.

Although I'm personally not concerned with the power usage. I'm more concerned about price / performance ratio.

Not sure why everyone is still beating BD down, isnt it getting a 40% boost from a registry fix

Another excuse is "windows 8 will fix it" but the funny thing is that windows 8 also helps other multicore processors as well which leaves the same conclusion, BD fails.

lol..wow.sadly almost true..you know..i lost my "wait and see how it does then wait for 6 mos" on this one..hopefully they (Amd)come out with something better..cuz this a drastic 2 steps back i skipped phenom1 back in the days when i had sense ..then jumped on the II series soon as i read the reviews..somehow i lost that.well..it's been two years..and i expected amd's current release to be at least a smidgen better than their last..it's not..it's about as powerful and fast as netburst..oh..and gappo's chip DIED
