Idk if I'd call it misinformation. More appropriately, the word I would use is bull........ us. Aside from what little factual information we were told concerning the arch. Nearly every claim that he made refuting the pre-release leaked benchmark performance being not indicative of final production silicon were outright lies.

I don't believe for a moment, that there is any way that he was not apprised of the performance before hand. Further, in retrospect, although claims were made otherwise...I would be inclined to believe that his actions were sanctioned.

I actually thought that BD was a good idea originally - Kind of like Hyperthreading but with 2 integer cores - Just didn't work out for some reason. I just got a little miffed because I bought a Mobo for BD ( scrapped out a decent 890fx system to build a 990fx system ) and did not need to - I am actually rebuilding my old system because it worked better than the new one - largely did so on what that guy had to say .

If hadn't said this and actually refrained from commenting on leaks like he said, stuff would've been much better for him.

I am also skeptical. It didn't make much sense to me, I got out of my way to not support my companies products in any shape, sense, or form, let alone become a dedicated "Hardware Rep"

Well, he claimed not to be able to discuss performance. But then generally made accusations that the persons posting the leaked benchies may be planted by Intel (ironically, those benchmarks turned out to be right on target). That, as stated above in my earlier post, the performance in said benches was not indicative.

Then there was also a rather large argument on XS between JF-AMD and another member concerning the IPC decreases in which he vehemently denied that IPC would decrease. In that, and many other places on the net, you may find JF stating it as fact that IPC would increase. A point which has been patently proven false at this time.

And can your core 2 max out your gtx480 SLI, and pull the same ppd as a 2500k, which you claimed was the problem with BD, yet it's clearly able to do?

And what facts are those? Because you've done nothing but troll, and anytime you've been confronted with results that show the opposite of your trolling claims that BD can't hang, you have nothing constructive or intelligent to say, other than out-of-context quoting.
Yeah, look first things first I'm not trying to get another thread locked here or troll but - I don't know why you're trying to imply that if a BD Computer boots up - it's adequate for anything we may need to do. I give you two examples where that is not the case (Multi GPU Setups & Folding) and you start making excuses and ignoring anything consequential. i.e. Never mind more powerful GPU's are set two launch in two or three months, or how much power is required to fold on BD... Then you call anyone who points out the truth "Unintelligent, uninformed". Who do you think you are fooling around here? How many BAD reviews have been done on BD? Now we are discussing FOLLOW UP bad reviews on top of the original bad reviews? And then, to make things even more confusing, you post this -

you say "it flopped in that segment". My question to you is, what segment do you think BD was aimed at if not computer enthusiasts? And if it flopped at the segment it was aimed at, how can it be considered anything but a flop?

He claimed a lot of things on multiple forums !
I am unsure but did he ever apologize for misleading people ?
It cost me $160 , I wonder how many other suckers bought into it .
I will have to watch out for people selling bridges in Sanfrancisco

Oh wow, I didn't know that all went down. Interesting, I'll have to look it up.

And weren't you saying before that you fold, and BD isn't suitable for that either, when in fact it nets the same ppd as a 2500k?
Which BTW is hilarious as F@H has a disclaimer about using AMD cpu's due to their choice of using the the ICC becuase they wrote F@H with fortran.

# What about AMD support? We are currently using the Intel Fortran compiler and libraries. This software intentially runs slowly on AMD CPUs (SSE2 is not supported). While there have been hacks around this issue, such modifications violate Intel's EULA. At FAH, we follow software EULAs and are thus bound to this limitation imposed by Intel.
# That's not fair to AMD chips! Yes, it isn't fair and AMD is taking actions against this. We hope that things will change, but our hands are tied here. We could give these WUs to AMD machines, but they would have a much worse points per day (less than half of what one gets on Intel hardware) and would not perform well in general.
# What about new chips such as the PentiumM or Pentium 4M? New CPU id's will be supported once the CPUID code is updated in the v6 client.
# Why not just use a compiler that legally supports SSE2 on both Intel and AMD CPUs? Currently, the best compiler (speed wise) for QMD is the Intel compiler (by a factor of 2x). The AMD compiler is pretty good, but is limited (license-wise) to AMD chips; however, it is not as fast or as optimized as the Intel compiler. We have not found a compiler which has no restrictions (runs on both Intel and AMD) which close in speed to that of the Intel or AMD compilers.

Yes, that was in relation to this question -
