Again, that is a stupid argument, especially given that the 2500K with comparable performance, price, and over clock, achieves this with a substantially lower power consumption on load.



Are you seriously trying to compare a new gen CPU to a last gen CPU? It is common knowledge that Nehalem was hugely power hungry and an issue Intel succeeded in addressing with Sandy Bridge. Nehalem was also the most powerful processor upon release, so the performance crown justified the higher power consumption from an enthusiast standpoint. BD has not seized any performance crowns, while having a much greater power consumption level. Short of being a blatant AMD fanboy, there is little justification for recommending a BD build unless you are simply upgrading the CPU, of which you may need to upgrade your PSU as well.
Price/performance, Sandy Bridge blows it away except for heavy tasks, then BD is great for its price if it is utilized for that.

I do agree with him that the power consumption is blown out of proportion. Yes, they promised better efficiency, and it did not deliver as much as Intel's chips did or as much as expected, but many people are making comments like "OMG I WILL NEED A NEW PSU!!" which is just flat out not true. Also, the way different review sites calculated power draw adds to the confusion, as some measured at the wall for the whole system, some accounted for PSU efficiency, some tried to isolate the CPU's power draw, etc, giving a huge range of numbers that most people have no clue what to do with. It is sub par compared to what was promised/expected, but it is not as big as some people make it out to be.

What a lot of us power naysayers are trying to point out is that for something that ONLY offers comparable price and performance, there is no excuse for it to be using as much power as it does when it's competitor is offering a more than competitive product that has much lower power draw. To try to justify it as more cores so it scales or that it is comparable with last gen Nehalem is not a legitimate consumer argument. AMD flopped on the efficiency side of things and considering how Intel's products are currently just as good if not outright better, that is a huge factor to consider.

Oh believe me, I agree with you. I'm just pointing out that some people are blowing it way out of proportion when they see a review state that it pulled 500W, and they think they will need a 1000W+ PSU to run this chip.

Have we reached so low that we find excuses for a mediocre product? What's with the blatant push to shut one eye and ignore the lack of performance in areas where AMD has brainwashed half of the internet? How many here on ocn drank the amd kool aid and now are willing to let it slide? Where is the objectivity, heck you've been made fools by a company who has done nothing else than damage limitation since the official launch. You blame INTEL's business practices yet you accept to be made a clown by AMD?

AMD has lost its credibility as a chipmaker. All the attacks the AMD folk have done ...'INTEL will be Bulldozered' 'Unrivalled performance at half the price'. Some here need to grow some backbone and think for themselves. How easy are some manipulated (eg the world record attempt). How many tens of pages did we have after the 8GHz record that BD will rape INTEL?


This whole BD soap opera was rotten from the core. AMD did not expect SB to be such a good performer, saw the true potential of BD as a close match to Nehalem and decided to play another card 'don't trust ES samples. Performance will be better. IPC will be better. Single thread performance is better".


This should be a lesson for some to wait until they purchase brand new mobos for a chip they haven't seen in action.

hmmmm regardless of it being a flop, i think BD needs more testing, and more criative tests at that!!

so far, from what i've gathered:
-performance scales with clock (obviously)
-performance scales with HTT clocking (interesting and it's quite more than I expected)
-performance does not seem to scale with NB like phenom did..
-performance per thread increases with 4cores, 4 modules instead of 8..

still want to see how 4M/4C approach affects temps, power consumption and max OC ceiling on air/water!

I have to agree with this. They even posted some gpu-bottlenecked benchmarks of BF3 on their blog. Saying that Bulldozer is better than 2600K. 1fps difference of 2600k and Phenomâ„¢ II X6 1100T? No way. (no clock speed info or etc, could have at least said it is at stock settings or something)

Check out this post I made in another thread.

It looks like mid-late Q1 2012.

Of course, this is from Semi-Accurate.com, but it does sound reasonable.

Right now there simply is not any real place for BD with Intel's current offerings. I can see a future where once OS systems and programs become more adept at multi-core management and we can benefit from AMD's proposed modularity and scalability of their architecture. However, they NEED to get the power down!
