IMO they took a wrong gamble by making BD their own version of Intel's Pentium 4 in which they targeted higher clockspeeds over IPC performance
*

The only last hope they have is like what Anandtech said, to repeat the success of Pentium 4 northwood. pentium 4 northwood does beat the AthlonXP by seer amount of extra GHz without hitting the power consumption too much. It actually fix what Willamate Pentium 4 cant do. Not until Prescott Pentium 4, Intel just broke their own arm by increasing the pipeline further in Prescott. Infact Intel manage to increase the pipeline of Prescott without sacrificing the IPC, but unfortunately they ignore the heat and power wall they gonna hit when they reach 3.8GHz. In this case they have to rely on the mature 32nm global foundry tech or may be even smaller to archive it.

BD should have clock @ 4GHz+ not 3.6GHz. If they have release BD 1000MHz extra @ 125w TDP from now. nobody will have complain.

so AMD Bulldozer FX-8150 better or Intel Sandy Bridge i7-2600K better now? Quite confuse now! blink.gif

Maybe for Battlefield 3 the FX-8150 performs well, but for the majority of the games the Intel Sandy Bridge processors are still much faster. smile.gif But still for the i7 2600K to lose 5FPS when overclocked to 4.8GHz compared to stock speed, it doesn't seem right smile.gif.

Note that BF3 is quite difficult to benchmark identically due to the game being purely multiplayer right now. No similar test run can be done on different systems atm.

The unboxing of the FX-8150 if anyone is still interested in knowing what is inside the box. Looks like it is a special edition with a lot junk freebies that you pay.

Dont forget by March 2012 Intel will release Ivy Bridge which is claimed to be 60% faster than Sandy.

The performance gap between these two will be widen by far margin, again.

.......

Intel claimed that 60% ....is on its GPU part...

clock to clock compared with sandy bridge... i dun think ivy bridge will offer above 10% improvement.

IMO, AMD should stop all the hype and downplay (i.e. the comic, video clips).
She should fully focus on developing a solid product.
Let the product speak for itself.

Before that, she should fire all the marketing staff. I can see AMD sucks big time in all marketing strategies (beside the strategy of staying low/aka selling cheap).
Selling cheap is not going to help. Intel price higher but the Intel products still sell like hotcakes.
Look at the market segmentation, it is all screwed up (Zacate killed K125/K325/K625. Llano killed Zacate and Radeon GPU in notebook market).
Look at the market awareness, AMD has not done enough to educate the people that her K125/K325/K625/Zacate netbook segment is way way better than the shitty Atom (yeah, I know people only started realizing it this year. But Atom has been selling like hotcakes for so many freaking years).

IMO, AMD shud learn from the GPU team.

remember how ATI ditch the big die stratery & opted for small die, performance per watt & performance per price ratio?

since 4k series onwards, they's been competing wit nvidia big die strategy.
yes, ATI chip lost in the highest end in terms of pure performance, but win in every other segments.
most importantly, bcoz of the cost of the chip is low, they profit more than their competitor.

now, seams that the AMD CPU division has fallen in to the same trap that nvidia did wit big chip.
hard to mek, low yield, even if it's sold, it wont generate much profit coz cost is high.

K125/325/625 were meant to be replaced by Llano anyway, after all they were grossly inferior in power consumption. Llano won't kill Radeon GPUs: those Radeons still have buyers in Intel laptops, look at how many get purchased by Apple for MBPs and iMacs for example.

I speak from my experience.
K125/K325 are in the netbook segment.
It was killed by Zacate.

I owned an Acer Aspire One 721 with K125.
It is already a kick-ass APU that wiped out all shitty Atoms.
I bought it from Singapore when it first launched in Aug 2010.
It was killed (or completely replaced) by Zacate in less than 6 months.
What kind of stupid marketing strategy was that?

Llano notebooks are now equipped with "Radeon 5650/6550" (in cross-fire mode).
Radeon 5650/6550 are virtually vanished in sub-MYR2000 and sub-MYR2500 notebooks.
Where have the GPUs gone? In Llano notebook where AMD needs to cross-fire it with Llano APU (otherwise, the performance sucks).
What's left in sub-MYR2000 and sub-MYR2500 segment are Radeon 6470 & 6630, which clearly a lower grade and not able to compete with nVidia GT525/540.
Radeon 5650/6550 notebooks used to be found in MYR2000-3000 notebooks.
Where is Radeon 5650/6550 now? in sub-MYR2000 Llano notebook.
This is what i meant AMD killed the Radeon. Extremely poor strategy.

P/S Those Radeon found in Mac are higher end Radeon 6750 (and Radeon 6490 for lower end).
The one in between Radeon 6490 & 6750 was killed (or rather run in Llano system now).

This is a review from Tom's hardware.

http://www.tomshardware.com/reviews/fx-815...990fx,3043.html

It is comparable to the previous phenom II x4 980 in gaming. The Phenom II costs $170 and is based on a chip 3 years old. The FX-8150 costs $245.

In productivity it is usually on par with the i5-2500k, a 1-year old chip which costs $220.

Overall, it is a huge disappointment. Oh, peak wattage for the highest line of Bulldozer: 252W. [ What in hell? ]

MSI is pleased to announce that OC Genie II on the upcoming MSI AMD 9-series mainboards will support world’s most advanced automatic overclocking. With just the a single push of a button OC Genie II not only increases your processor and memory speeds, it also unlocks up to 8 CPU cores. This makes OC Genie II the simplest option to increase your performance on a MSI AMD 9-series mainboard up to 250%. MSI’s upcoming AMD 9-series mainboards are built to the highest quality standards: MIL-STD-810G certified Military Class II Components. Military Class II components give you the best efficiency and highest performance on the upcoming AMD 9-series mainboards.

MSI’s 25 years of knowledge in mainboards and over clocking has delivered some remarkable results. With  the world’s first overclockable mainboard, which was a 80286, to the simplest ease for end-users to upgrade their PC performance up to 250% with a simple push of a button.

OC Genie II performs these tasks with a single push of the button:

- Unlock hidden CPU cores
- Adjust CPU clocks (up to 8)
- Adjust CPU multiplier
- Adjust CPU voltage
- Adjust memory speed
- Adjust memory voltage.


Sucks to be AMD, but I guess now nobody's going to even consider the FX-8150 right now if those FX-4100 chips can unlock the other 2 disabled modules.

Well, a lot of reviews said that the 8120 was already a better buy than the 8150.

Just a quick question: Is the integrated graphics on the AMD A8 3850 faster than a i3 2100K and GT 430?

I think all this shouting and face palming over benchmark result is due to misunderstanding and over expectation.

1. This is like a reboot of CPU architecture for AMD. Is like 1 step of many to reposition the CPU by de emphasize FPU performance. Because at the end of the road Bulldozer architecture will become one of the Fusion. I.e more emphasis on floating point calculation on the GPU.

2. That is why AMD has 4 year roadmap. And the fusion thing should happen on next year Piledriver roadmap. It sucks this year on gaming benchmark, so much pitty for early adopters. As always!

3. Bulldozer, being the first in the roadmap also means software support is not here yet. Anand tech review bring up some thread scheduling issue on the different cores of Bulldozer with Windows 7. Which should be solved by Windows 8, next year. Support in Linux kernel should be sooner (just my opinion) since Linux is popular as server.

4. Which bring this to my next point. AMD need to "cari makan" also right? With Intel being so powerful in the main stream performance CPU market. Will be very high risk for AMD to go head to head with Intel in that particular market. If "untung sabut" then everything is good. If "untung batu". How then? So this time around (again this is my opinion) they put a CPU that will sell good at that price to the servers market. Hedging that server market (with premium margin) will support further effort to tune the architecture for Desktop in the next iteration.

5. Untill then, looks like AMD trying to promote the Bulldozer to enthusias as over clocking friendly CPU. Really have no idea whether this is good or not. But personally I won't have some thing that hot and eats lots of electricity in my house!

So I hope what I wrote above can give you guys a better perspective. Do understand that there is a lot of disappointment (me too!). But this has to happen before AMD really can get competitive again.

Unfortunately this means it sucks to be early adopter OR it is another wait. But we have a similar wait with Phenom -> Phenom II right? So what is another year.

Cheers!

Next year, AMD will be competing with Ivy Bridge 22nm with 3D transistors. It won't be easy.

Yah, they be fighting with 22nm Three gate field transistor based CPU, but it also happened to be the first of its kind, problem could show up who knows
