AMD Zambezi news, info, fans !

FlanK3r probably something new will be presented this Friday at Hot chips conference of course no benches but maybe some new info about the architecture.

Olivon maybe I am wrong and he really has BD samples but thats something only he knows.
His post about how he can't compare BD to SB or Gulftown despite the fact so much reviews with different tests are out didn't add to his credibility, but maybe I am just misunderstanding.

I hope that, at Hot Chips, they can explain the performance degradations on the Software Optimization Guide:

-----------------------

Note: For best performance, do not mix streaming instructions on a cache line with non-streaming store instructions.
The following performance caveats apply when using streaming stores on AMD Family 15h cores.


•When writing out a single stream of data sequentially, performance of AMD Family 15h processors is comparable to previous generations of AMD processors.

•When writing out two streams of data, AMD Family 15h version 1 processors can be up to three times slower than previous-generation AMD processors. AMD Family 15h version 2 processor performance is approximately 1.5 times slower than previous AMD processors.

•When writing out four non-temporal streams, AMD Family 15h version 1 can be up to three times slower than previous AMD processors. AMD Family 15h version 2 processor performance is comparable to previous AMD processors.

•Using non-temporal stores but not writing out an entire cacheline may cause performance to be up to six times slower than previous AMD processors.

------------------------

It seems that this problem will even be (at a lower rate) on BDv2.

How will this affect BD performance on benches and "real world"?

Yes there is misunderstanding, i do not look at other peoples results or if i look i wont take notes of them.

Cannot compare SB or Gulftown to BD since i dont have working X58 or Z/P67 board at the moment. I have 980X and 2500K and 2600K cpus tough and 980X is pretty close 990X.
I lost alot of hardware at thunderstorm this summer, servers and my main pc is behind ups unit but other pc's and benching hardware isnt.
I didnt loose BD and 990FX since they werent plugged in at that moment.

Lost 6000$ worth of hardware and im not going to risk that again, now everything is behind ups units.

Would you say the Bulldozer is worth waiting for?

Id say yes, need see its price first tough.
