thank you.sorry now i got it but the thing is quad core BD is placed lower than the Athlon II quad cores.this is very very bad for AMD.are they moving forward in past or future.I am not understanding at all.though looking at the 8150 position we can say AMD is lagging behind just by a hair with Intel's best.but still if i am going to buy a processor i will go for i5 rather than 8150 because i don't want to make electricity companies crorepathies.
BD may have a bright future with future programs able to use it full features but still power is a very big concern in these days where there is a lack of electricity production in India.

After reading tom's, i see that i5 2500k and i7 2600k are still the processors of choice for a new system build which includes the enthusiast and gaming platforms. Lets see what fx 6100 and 4100 bring to the table and see if they can manage to steal the limelight from i5 2400.
this is what I'm thinking right now... why not they tested the cpu performance ( in dev stage ) with benchmarks ??
as many of you already told I'm considering it something like GTX480 for which we were able get the world fastest single gpu like GTX 580 - they will learn a lot from the this and the next cpu might be better than this,
in 2003 AMD Brought 64-Bit Computing to the Desktop and on the 10th Anniversary they might bring another wonder in desktop cpu world .
For me - I will wait for the next cpu release ( from both side )

This was their performance series right ?? If it performed like this then what can we expect from future releases. I can't understand what happened to AMD are we on the road of Intel's monotony ?? Still I have hope for them. Come on AMD do something. Now waiting for 7000 series. I hope that wait would be fruitful.

so Sandy bridge still rules ..!!

oh wow...Xenforo!!!
A lot of people in multiple forums (even the international ones) are banging their heads against the walls. Its sad and I feel genuinely bad for people who waited for atleast a year. AMD is clearly damaging its loyalty. Phenom deja vu, anybody?

I am already banging my head. This was their best chance to defeat Intel. They must do something radical here to remain in close competition.

Yep, this one was real bad. I expected a lot more from Bulldozer. Llano was more exciting than this (although it was not for enthusiasts). They should have launched this 6-8 months back and they could have introduced the next series early next year.
They must remember that the price differences compared to Intel are not as much as they were 2-3 years back. So AMD loyalists won't be hanging on for long

I am damn sure that they knew about the performance and power consumption problem of BD but still why they tried to compare it with i5 and 980X.they were just openly comparing their bd benchmark with the intel one.when their BD was not up to the mark then why did they tried to compare it with SB.i can't understand AMD.but still lets wait for 3-4 months and see if there any revisions get s released with these things fixed.

Guys, one good news for AMD. Just checking the Anandtech review and found out something useful.
Anandtech also tested X264 encoding using a moddified Binary compiled to support AVX and AMD XOP instruction set and found out that in 2nd pass (which is the original pass where video gets encoded originally) FX 8150 is beating out i7 2600K.
This is really interesting because this example shows how an optimized application for AMD Bolldozer architecture can be benefited and has some serious performance boost. Hoping to see some patch releases to optimize Bulldozer's performance.
Check out here. In Windows 8 preview there is a performance improvement ranging from 4% to 10% over Windows 7. The reason given by AMD is that Windows 7 Scheduler is not aware about Bulldozer's module based architecture and places threads wherever it finds a core is free, rather than judging the state of the module. For example suppose at time t Bulldozer has two free modules (that is 4 cores to OS) and there are two threads waiting for OS to schedule them in CPU. Now if OS is not aware of the modules, it may assign both the threads to the cores of a single module, resulting low resource utiliztion, confilts etc as we all know two cores of a module are not totally independent, they share Fetch-Decode, FP unit and L2 cache.
Now if OS is aware of the modules then two threads can be assigned to two different modules. Here each of the threads gets two cores to finish execution of the instructions present in each of them, resulting faster execution.
Similarly it will also help to improve the Turbo core performance. For example if two threads, say Th1 and Th2 where Th2 is dependent upon Th1, are present, they should be assigned to the two cores of a single module to improve resource sharing and to cut down all the other modules to reach at the peak turbo speed when a single module as all the other module are not in used and can be cut from power.
In Windows 7 it is not possible all the time due to OS' inability to recognize the modules.
But if the OS is aware of a module and the cores inside it, those problems can be addressed and scheduling can be done in much organized manner.

^^That is what i told in my previous thread....not in a explanatory way as you did ,but......the point is we dont have applications optimised for BD,that is the reason we have this low scores in benchmarks.
and the high power consumption is due the faulty TMSC manufacturings.
If applicaions are optimised for BD's architechture in future then we have a good processor in hand.

I know it, Max. In fact I am much disappointed than others because of Bulldozer's not so gr8 performance. But you believe it of not, AMD is the pioneer of lots of concept which are groundbreaking and more futuristic than Intel. In fact Intel Nehalem and Sandybridge have taken lots of those concept from AMD to imrove their performance. Examples are On-Die memory controller, Serial linking between CPU and Northbirgde instead of FSB, True multi-core architecture etc.
Here AMD has developed a completely new and out of the box design for SMT which is really great but it is actually little ahead of its time. As a result lack of proper OS and Application supports driving it back in terms of performance.
I am just hoping with latest Windows patches, application releases and with Windows 8, those problems will be addressed in some extent so that we can fetch a little more performance from it.

But by that time, the Sandy Bridge-E might be out... If this happens & this is true, AMD will drown...

Before the release i was so tempting to buy this processor so that my aging c2d can retire...but benckmarks have somewhat pulled me back...still if i find this in a reasonable price i will surely try one...coz ivy-bridge is not coming sooner and who wants to buy sb-e which will cost a bomb in India.
Ivy bridge is coming in march-april till then BD will be back in new avataar "piledriver" to compete...and hope till then current BD will be more mature......
IMO its still not a fail as phenom-1 was in early days.
End user will get to know no difference between sb and bd when general computing.
As far as games go if sb gives 90 frames and bd gives 80 frames in a particular benchmark..who cares,can u spot the difference while gaming????
