If it was just Anand saying Barca was in trouble then maybe you'd have a point but when I see the same thing reported on one of the least biased tech sites I tend to get a bit suspicious.Originally posted by: tuteja1986
No.. thats anandtech being angry with AMD as whole. I remember many article of Opertron in trouble and they were running at very low speed just few months before launch.

The best a processor can do is 1:1 scaling as clockspeed increases AFAIK right?
So scaling clockspeed up will show what potential performance at higher clocks will be.

Barcelona thermal dissipation is fine at high clocks Even over 2.8 GHz
Our knowledgeable sources have confirmed that Barcelona is going to be an overclockable part. Even at 2.8 GHz to 3 GHz this processor won't have any TDP dissipation limitations. TDP stands for Thermal Design Power and is a very important figure as this is the power that has to be removed from a CPU. You need to cool this thing of to make it stable.
The new revision that a few sources referred as B1 shouldn't have any TDP problems and it can work up to 2.8 if not higher to meet the standard TDP numbers.
The main problem now is to get enough of these chips out on the market and even if AMD launches Barcelona in Q3 we are talking about a few chips in late September. Realistically this chip is Q4
thought id share this for those interested , i also read somewhere there is a b2 revision but
b1 will be good enough and be able to hit decent clock speeds, i think the b2 revision will be able to achieve even higher clocks and still stay within the TDP limit
Gotta run, need a mac to run my office apps faster!Originally posted by: sdsdv10

Hey lopri, did you see this article. http://hubpages.com/hub/_86_Ma..._Wont_Believe_Who_Wins
They compared a '86 Mac Plus to a '07 AMD Dual core machine in various MS Word operations. Guess which one won! ;-)
Now before anyone gets their underwear in a bunch, I realize the comparison was done a little ?tongue in cheek?, but I think it illustrates lopri's point. In the productivity arena (i.e. MS Office), the advances in hardware have not been matched with advances in software. Yeah, they have added more and more features to Word, etc., but the underlying code has not improved to the same extent. Games, well that is an entirely different story. However, the vast majority of people don?t make a living playing games at work. The bulk do use some type of productivity software in their day to day job.

Actually, I'm not sure if performance scales 1:1 with clockspeed.
2ghz = 1/2 billion s cycle time (.5 nano seconds per cycle), right? Let's say it takes 5 minutes for something to finish at 2ghz.
2.6 ghz = 1/2.6 billion s = .38 nanoseconds per cycle.
Doing a ratio of
.5/.38 = 5/x, you'd get that x equals 3.8 minutes.
2.6 is 30% higher frequency than 2ghz, but 3.8 minutes is only 24% faster than 5 minutes.
So in actuality, the best a processor can do is a bit less than 1:1 scaling.

hi nyker,
well yesterday there was only a handfull of news sites with the information but theres many more today.(google it)
The launch revision B1 barcelona, New Opteron and new desktop Phenom or Agena FX CPUs will be able to hit 2.8 GHz, clocks between 1.9 - 2.8 ghz
Q3/Q4 fx-80: phenom FX/AGENA FX 2.2-2.4, 3.2ghz??? AM2+
the B2 revision budapest is K10 core but with native HyperTransport 3.0 and word is that the fx series should go upto 3.6ghz.
Q1/08 fx-90: PHENOM FX/AGENA FX 2.2-2.6ghz, 3.2ghz 1207+
Q1/08 fx-91: PHENOM FX/AGENA FX 2.4-2.6ghz, 3.6ghz 1207+
it looks like the NEW opteron will be available next month:

check under Opteron 2000 QC Series.
its all i have for now.
