They could have just leave the BD away from the comsumer market. Many cores doesnt work in this area.

Just give the K10/phenom II a 4 issue instruction (like Intel gave its core architectural from a P6) + give K10 a 8 core then we will see AMD start completing at the level with 2011 SB-E.

No you're wrong. The stars design is very old. BD does work, it was due to poor scheduling coupled with poor yield which caused the flop. Had they been able to launch their processors at the intended clockspeeds (> 4 GHz, at stock), they could've captured the mainstream market, leaving the high end to Sandy Bridge E.

Maybe for you, you don't need a BD but I am sure many people would find BD absolutely great. It's just the pricing that needs adjusting, especially in Malaysia right now. At ~$200, the FX-8120 is a steal, which many people would not agree because they want a chip for games! And games would not utilize so many cores, it's the IPC that matters in games most of the time. The price of a FX-8120 should be around RM650 based on today's currency exchange but retailers here are charging for RM768 based on lowyat's pricelist. That's the only factor that prevents me from purchasing.

Well because AMD promotes it as a gaming proc? Their demos with Dirt 3 showing utilisation of all the 8 cores? hmm

Regardless of what they promote it as, you can't just go around and say that they flop because they run a few FPS lower than Phenom. As an overall processor, it is clearly better than purchasing an i5 (I'm talking about FX-8120 here, because FX8150 is being too expensive) because of its raw processing power and lower overall platform cost.

I think there is a huge improvement on the CPU just that Intel held back. IB is running on 77 TDP "could be largely factor by its IGP power consumption" and still performance slightly higher than SB.
with the disappointment on BD performance and power consumption and also not to overshadow SB-E probably the reason y Intel held back. Intel could make a 95 TDP IB but it would seriously destroy SB-E. hmm.gif
Anyway it just my opinion. biggrin.gif
Regardless it is interesting to see Intel put more effort on its IGP and it just matter of times for intel to catch up with red camp and green camp.

It won't happen anytime soon. Intel still has a long way to go in the graphics department. If you were to look at the benchmarks closely, the results were skewed to make HD4000 graphics look nice by comparing it against HD2000, relatively. Why not the HD3000?

Problem is their marketing had failed. period. no matter how good it is, the damage has been done by themselves by promoting the least good thing about the proc.

You're right. They fail at marketing. They can't even get their transistor count right. However, should we deny or count out its processing power just because of a failed marketing?

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
*
B3 will still have the IPC issue. It is only estimated to perform around 3 - 5% better than B2. The real deal would be PileDriver.

I believe the 2b transistor count was meant for Trinity with an on-die graphics processor, but their marketing people screwed up. If AMD can pull a QuickSync and does not have the mutually exclusive problem like Sandy's prior to the Z-series chipset, why not? It's all the more better. Kudos to AMD if they can pull it off with Trinity.

New update: AMD has decided to stop shipping Phenom IIs and focus their firepower on BD and Llano. It will take around half a year for Phenom IIs to run dry. Those on Athlon, time to upgrade.

Well, if they release an Athlon 631X Black Edition at its cheap price, I'm sure there are many enthusiasts who will disagree...
They need to ramp up Trinity production to meet OEM demand, since the 45nm and 32nm chips are produced in the same facility.

Here's an interesting thing to ponder: some rumours suggest a Piledriver-derived CPU in the Xbox 720. Would this make AMD the CPU for gamers again, due to future console ports being more optimized for their architecture?

I doubt so though. I still believe that they'd be using AMD gpu with IBM cell processors. Well, let's see how it turns out next year smile.gif

Initial tests showed that it could improve performance by up to seven percent, before it was pulled -- Microsoft conceding that it wasn't quite ready for prime-time.

7% will make it slightly above i5. Pretty good. Can't wait to see the actual release

A10 will be based on dual module piledriver cores, or Quad cores going by AMD's book.

Can't wait to see benchmark against i3 ivy
