[Official] AMD Bulldozer Reviews Thread - Page 43

post #421 of 2308
I said way back before the summer that bulldozer was decreasing instructions per clock as compared to previous gen, but I was laughed at.

Maybe, Maybe not. Its just cases like this where I read reviews/benchmarks before buying expense stuff. Especially computer hardware! Because its a mixed bucket

Well this is rather disappointing. My main thing is power consumption. If it performed better while overclocked and took less power (which i thought it would) this would be an easy choice. However power seems rather poorly.

Sad to say but when tomorrow comes I may be choosing the Intel 2500k, even though i waited almost 10 months for the FX.

Idk. Bit baffled.
Yeah, I read that and was amazed! But maybe that is why it runs so hot!

If this is the case, I don't understand AMD's angle, why did they think less IPC would be better than more?
post #426 of 2308
And I thought I almost made a mistake after buying this 2500K, guess not.... my 1090t is better than this thing, and I bought that back in May of 2010, AMD you disappoint me. this is a complete flop in my book, when the previous generation cpus beat out the new ones. Reminds me of the first gen pentium 4's

IIRC AMD themselves stated a single "core" within a bulldozer "module" will yield approximately 80% the performance of a full core.

The results are all over the place. I'm seriously wondering if a bump in the NB clock could eliminate some of the strange results that reviewers are getting. Surely it couldn't hurt.

I mean, about half of the results have the 8150P losing to the 1100T, and 50% of those lose to the PhII 980 X4. That's a serious misstep if AMD can't beat out their previous flagship product outright with their new one.

So after the QQ subsides, will we begin seeing, "Just wait for Pildriver to stick it to Ivy Bridge!"

Seriously AMD forecasts' a what? 10%-15% improvement per core in their next iteration due out next year?

Bulldozer fails hard. Incredibly disappointing. Intel seems the only way to fly currently for most desktop choices and certainly is in no danger of losing their crown.

I would guess that AMD:

1. Would have thought of that and increased the default frequency if they felt the performance was not up to par; they did it with the CPU clockspeed,

or

2. They would have told reviewers to not forget to overlclock the NB to get better results, seeing as the performance would take a hit otherwise.

Yes, but...

First impressions are important. Certainly AMD wouldn't have overlooked the patch?
+1

My thoughts exactly. If AMD knows about this problem - I mean they MUST know, they designed the chip that way, they had to know the implications and their internal testing would have shown that - their job was to work closely with Microsoft to address the issue as soon as possible. And after all, yesterday was patch Tuesday and nothing.
