Apparently ASUS CH5's BIOS is being blamed for the performance drop, we will see later how it goes

Asrock 990FX Extreme4 already shown us that BD can rival the 2600k in gaming, awaiting other boards

The benchmarks posted are all on high resolution.
In this case, the GPU is more important.
Why Bulldozer platform get slightly better FPS in high resolution gaming compared to i7 2600K when SLi/CFX, because the Bulldozer mobo gives x16/x16 while Sandy Bridge mobo gives x8/x8 only.

There are many reivews that compares clock-to-clock results as well (such as those at Tom's Hardware, HardwareCanucks, SweClockers.com, Planet 3DNow!, etc).  tongue.gif

That's incorrect because most of those reviews are using single card. The only reviews I've seen so far using SLI or CrossFireX are TweakTown and AlienBabelTech. wink.gif

I was talking about reviews with SLi/CFX.
Don't see anything wrong there.

AMD is going to release B3 stepping Bulldozer.
But I think the performance will not improve, but instead, reduces power consumption/increases overclocking headroom.

Hmm, Brazos 2.0 is coming. I think CPU remains the same, but with HD7000 GPU.

I'm wondering, Bulldozer is so sad already, kenot brain Piledriver already. blink.gif

Pretty much most likely there.
AMD so called quad core, just like FX-4100, dual modules. biggrin.gif
And yes, the mobile processor roadmap showed, there are 2 SKUs, placed top of A8-3850MX and another one is placed between A8 and A6. smile.gif

Is it all benchmarks were crippled amd?

That does not matter, as Bulldozer even shown worse than Phenom II, let alone Intel.

Why the Cinebench 11.5 multi-threaded result so much difference from the rest? 2600k just 0.01 point more than stock FX8150?

Cinebench fully utilize the whole processor.
Result for "8 cores" is definitely normal.

Llano sales are strong. Can they continue their success with their Piledriver platform? It remains to be seen for next year. But certainly, Q1-Q2 next year will be very interesting times for AMD indeed.

Mostly is OEM market? biggrin.gif

APU with onboard VRAM.
Looks like this is only the solution to fix the problem of memory bottleneck.

Saw Trinity engineering sample benchmark from chiphell.
3.8GHz, 4.1GHz turbo boost.
I believe it is 125W SKU.
The CPU uses Piledriver architecture.
Benchmarked in Cinebench, on par with current Llano only. doh.gif
How to compete to Ivy Bridge i3? No way.
AMD lost another card to play with.

Seems like AMD finally cranked up with their Piledriver, but still far behind.
Clock to clock on par with first generation Core processor, anyway, a good start, as it will be clocked around 3.6GHz.

I think it need another 1GHz extra to complete with Sandy/Ivy bridge.

Pretty much there.
But if AMD managed to get clock to clock on par with first gen Core, then high end Piledriver is somewhere near Sandy Bridge. hmm.gif

Who cares as long as it has better clock to clock performance.

Well they're going backwards. They are following the old netburst method. Another thing is the gap is too huge to bridge at one go and they're trying too hard
*
Then followed the history? Core architecture?
No-no. biggrin.gif, they still have long revision list of Bulldozer.
Piledriver, steamroller, excavator and helicopter? biggrin.gif
This made me recall the ppt slide from AMD, a risky process to them, as they can't afford to make big mistake due to tight of fund.

Llano is actually still fine.
AMD should increase the L2 cache from Phenom II series, made them in 32nm, should be able to crank up some clock, at least comparable to i3 2100 in gaming.
But sadly, they did this for their Llano only, but not flagship. hmm.gif

Anyway, news.
http://www.chiphell.com/thread-313546-1-1.html

Because of the volume manufacturing date of 28nm keep on being delayed, Wichita & Krishna APU latest launch date is Q3 2012.
So, AMD looks like, remove then half-year-lifespan Wichita and Krishna APU, focus their resources on Kabini APU. Hopefully it can be released earlier in Q4 2012.

By following the rumor, Kabini APU is first APU with Jaguar cores, and maybe have Graphics Core Next GPU, aka HD7000.

Jaguar is enhanced Bobcat, Graphic Core Next is also an obvious improvement, removing Wichita is fine.
Wichita is already taped out (Q2 2011), but it isn't useless, at least AMD can learn 28nm lithography from there.

More? Maybe this is Rory Read's Attack strategy.

There is Samara APU for tablet in 2013 as well.

Trinity Performance Leak
DonanimHaber is here again, they released a video that shows the Trinity APU performance.
Trinity APU uses Piledriver core and VLIW4 HD7000 GPU.
Here's the result.

We can see from above, Trinity SKUs has performance boost, increase 32% in 3DMark Vantage, 13.8% in PCMark Vantage compared to Llano SKUs.
The performance for crossfire-ing with HD6670 has nice performance boost too.

P/S : Calculated, Estimated. laugh.gif

Forget about Intel GPU.
Intel driver makes the GPU processes less detailed texture, hence FPS increases.
It is kind of "cheating". wink.gif

Anyway, AMD is working on B3 revision of Bulldozer.
Fixes :
1) L1, L2 and L3 latencies
2) Cache Thrashing Issues
3) Modified Algorithms for Branch Prediction
4) Healthy Bump in Processor Frequency
5) Slight Frequency increase via NB Controller
6) “Total Intelligent Control” For example programs and applications should look at the module design approach and the ability for the processor to intelligently turn off and/or turn on specific cores that it believes is hindering performance for maximum performance. (May be for Socket FM2, not sure at this time).
7) Power will be improved but not my much. We will have to wait for Socket FM2 or a future B4 revision for the AM3+ platform for better power efficiency especially when Over-clocked

Ah yes, interesting indeed, there is a video thingy on Trinity architecture?
AMD wants to provide something like QuickSync? laugh.gif

Oh, Microsoft said the update is scheduled in January next year.
Piledriver will be the next generation processor core architecture. smile.gif
The first to use the architecture is APU.
High end models, FX series is in Q3 2012.

Is it me or did the IPC dropped even more?

3.8GHz (A10-5800K) / 2.9GHz (A8-3850) = 31.0% gain
4304 (A10-5800K) / 3814 (A8-3850) = 12.8% gain

Oh AMD.... doh.gif
