That simply means all prices are Below $250... $1 is below $250 as well, but thats not the price. Though the other guy stated a vender or something released real prices, so oh well.

Anyone want to explain why they say it will be the first to have a "two cores working on two threads"? I'm confused...does this mean all the other multicore chips work two cores to one thread?

intel has 1 core working 2 threads, you are thinking of it backwards lol

So then why did Intel go to one core 2 threads instead of two core 2 threads? Or did I miss something when I read that? Seriously feeling stupid now.

well intel does 1 core 2 threads inefficiently (better than 1 core to 1 thread but not as good as how bd will work) bd will be doing 2 cores to 2 threads where the 2 cores share some resources... i think they said that for an additional core that shares resources with a core already on die you only need like an extra 15% die space

After what I watched on the live stream last night I wont even be buying one to play with no matter how cheap they are as it seems your better off with a Phenom II

Quite interesting, I've never looked at the architecture before. Basically what it comes down to is, thinking outside of the box (AMD is always clever in that department imo) can either massively backfire or be quite amazing. I find the front end to be especially interesting. In theory they are trying to get speed and accuracy, by having the fetcher and predictor the ablility to work independently.

I definitely had trouble with that sentence two. If I'm not mistaken, the first dual-core Opterons were capable of two cores working on two threads... I think the author was just trying for style...

wait, I thought it was 1 thread for 2 cores (1module), not 2 threads for 2 cores. Software is just starting to take advantage of 4 threads, so forget 6 or 8; the exception being multimedia software like vegas or photo shop. It just doesn't make sense to have 2 threads a module, and wouldn't that simply make things more complicated for the front end?

Threading is becoming more and more common as its the simplest way to gain performance these days. Double the cores is easier than double the frequency really so thats how it will go from now on for a while... or become a balance of the 2... who knows.

I think though, that with the slow adoption rate of going past 4 threads is gonna hinder BD and make it a niche CPU maybe... although it has a special 2 way turbo to deal with both scenarios theoretically... It can turbo a core in each module to a higher frequency when running lesser threaded applications while turboing all cores to a lower max frequency for highly demanding tasks... how well this will work, right out of the gate is any1's guess. I'm hoping there is something being held back till launch to make BD look better than the few leaks we have... though there are issues with the leaks...

I think BD will be crippled by the times. It might simply be ahead of its day. But again, who knows. Lets wait a few more days. I'm getting excited!
