As expected, the AMD bulldozers are giving intel solid competition, two and a half years ago.

I'll admit, the margin was slightly bigger than I anticipated. However, my only expectation was that it would compete with Sandy Bridge. It does in some respects, but like they said, no program out there utilizes the multithread of the cpu to even give it an edge. I'll prolly still end up getting one, as there isn't a program I'd run that would perform poorly just cause I had it over a Sandy Bridge.

It also is much less energy efficient than Sandy, costing you more KWhs and require more cooling.

I am highly disappointed. If Intel gains even more of the monopoly, it wont be good for anyone.

Now, we did some digging and found out quite few interesting things. Here is a quote from the AMD ex employee himself, who posted few comments about the whole situation some time ago:

   
Quote
On paper bulldozer is a lovely chip. Bulldozer was on the drawing board (people were even working on it) even back when I was there. All I can say is that by the time you see silicon for sale, it will be a lot less impressive, both in its own terms and when compared to what Intel will be offering. (Because I have no faith AMD knows how to actually design chips anymore). I don’t really want to reveal what I know about Bulldozer from my time at AMD.

    What did happen is that management decided there SHOULD BE such cross-engineering ,which meant we had to stop hand-crafting our CPU designs and switch to an SoC design style. This results in giving up a lot of performance, chip area, and efficiency. The reason DEC Alphas were always much faster than anything else is they designed each transistor by hand. Intel and AMD had always done so at least for the critical parts of the chip. That changed before I left – they started to rely on synthesis tools, automatic place and route tools, etc. I had been in charge of our design flow in the years before I left, and I had tested these tools by asking the companies who sold them to design blocks (adders, multipliers, etc.) using their tools. I let them take as long as they wanted. They always came back to me with designs that were 20% bigger, and 20% slower than our hand-crafted designs, and which suffered from electromigration and other problems.

    That is now how AMD designs chips. I’m sure it will turn out well for them [/sarcasm]

    BTW, you ask how AMD could have competed? Well, for one thing, the could have leveraged K8 and the K8 team’s success and design techniques instead of wasting years of time on a project that eventually got cancelled using people that had never achieved any success. It took Intel years to come out with Nehalem, and AMD could have been so far ahead by that point that they’d have enough money in the bank that they wouldn’t have to accept a low-ball settlement offer in the antitrust suit and they wouldn’t have to sell off their fabs.

Gives a totally different perspective on why Bulldozer failed, doesn’t?

Stay tuned.
