As far I'm aware the client is based on the server, and that server and client are almost identicle apart from clock speeds and sockets, they're all made from building blocks of basically the same modules. The 16 core server is effectively two 8 cores side by side, from this you can guess the 8 core has a substantially lower TDP at the same clocks or higher clocks at the same TPD. That's why it's relevent to us. Whilst there was a rumour a few days ago that BD will be 3.5Ghz stock with 500Mhz turbo, it was just that a rumour, we didn't know if it was the server they were talking about or the client either - we still don't know stock clocks, but we have it from the horses mout that the server will turbo up to 500Mhz on stock settings - this is new.

As I understand it, TurboCore pushes the clocks closer to the TDP limit? So if we OC these chips manually closer to the TDP limit, then TurboCore is moot?

Honestly I'm beginning to think these chips are designed for server market in mind with no regards to consumer market.
Since when did overclockers stop at TDP? Remember, these turbo settings are all stock settings - not overclocks. They're handy in that they give you a glimpse of what could be. It could all be just a kiss and a promise, but it's got my interest again.

AMD has another guy for that job.

The consumer market can look at features all day and go "ooo...ahh...that's shiny and pretty..." but at the end of the day we only want 3 things:
1.) Pricing
2.) Performance figures (benchmarks)
3.) Availability (for the whole system)

We want nice boards that are easily available for cheap chips, that'll overclock like mad, and already perform well at stock.

The only REAL feature that a consumer looks at on a CPU most of the time is the "Black Edition" "FX" "Extreme Edition" or "K Series" designations to know that at least the clock generator multi is unlocked so they can increase the frequency of the CPU.
Yeah, that's true. But they're also still going to market these features on the boxes and detail sheets for the consumer market, right? So it looks "pretty pretty" to the consumer market but in reality, they're used primarily by the server market and a benefit to the average joes. I guess we'll wait to hear from the consumer market AMD guy to see if there's something else in store that'll attract the consumers.

Those 3 points are what we mainly care for as overclockers as well as the REAL feature as you said. But for that newbie guy that wants to buy an AMD chip because he heard that overclocking them is easy now and reads the feature about TurboCore... well kinda misleading isn't it?

Me. LOL. Unless I'm doing it wrong because I'm a newb still learning or the data on my hard drive in my head has been affected by Intel's chipset due to degradation of my ears/eyes port. Pretty sure the only chips I've been able to afford are ones locked at TDP's. And I can only afford a $25 air cooler such as the 212+ so thermally I'm limited anyways. I take donations of Black Edition chips and a water-cool set up. Though I have found any givers.

I'm proud of what it could be but I'm just looking at it this way: I myself goes shopping for a new chip. Why would I buy this chip over another chip? Reviews and benchmarking shows outstanding performance by the Bulldozers. "great!" I buy one. Of course the price tag also includes these other extra features that are also on the chip. But I overclock the chip and now I've just lost my money's worth spent for the extra features that didn't have to do with me. Granted I'm still going to get the outstanding performance, but dang those extra few dollars spent on new techs.

The last part of AMD's mission statement states "To achieve success, AMD combines innovative concepts with leadership in process technology and design and manufacturing excellence to offer products and services that reduce the cost, improve the performance and shorten the time to market for our target customers worldwide." So to me it's like having to put "except the overclockers" on the end of that statement.

If only AMD can just drop all features that overclockers don't care about just to squeeze more dollar off the cost of the chips. Of course that would probably only be a couple of dollars here or there. And of course the average joe's market exceeds the enthusiast market. So my point is moot as well.

Or maybe I'm just being delirious and need to re-read everything and think when my mind is a little more clear...

There's nothing misleading about it; and this feature will be great for most average Joes as they'll get an extra performance boost without having to do anything.

After reading this the whole Turbo Core deal makes sense. For those having trouble it works like this. Your stock clock is what you are guaranteed to get out of the chip. The Turbo Core clock is extra power that the chip can tap into if the work load is high, but the chip still has power draw left over. It'll keep scaling the CPU up until it hits it's programmed safety limit or the limit of what power it can draw.

We still don't know what the TDP is, on say the 8 core client yet, for all we know it could allow the turbo to reach 6Ghz on one core. If it did, I couldn't care less if I couldn't turn turbo off and go beyond TDP!

New to the forums...

When I read this I was thrilled -- I mean 500Mhz over 16 cores! Though as I understand it that is only for 16 lightly loaded threads. If the CPU load is near 100% workload then you are very close to TDP anyway.

This does give some idea as to the BD overclocking headroom, however, after thinking about it for a while I can't help but wonder if Gamers who are still primarily concerned with lightly threaded apps - games still basically only use 2-3 cores - will have some tradeoffs between max OC on 1/2 cores with Turbo CORE on and max OC over all 8 cores ( Turbo CORE off)... so long as we are only talking about Turbo CORE fixed to using the reference (stock) TDP. It is definitely possible that at stock vCore and near stock clock speed you may get a getting a better OC of 2 cores w/ Turbo CORE than a traditional OC over all 8 cores with air cooling.

Now what be really cool is if as you change vCore the TDP reference for Turbo CORE changes accordingly (pre-defined by AMD). Or better yet, if we could change the Turbo CORE settings and control the TDP reference ourselves. May JF is not allowed to comment on that level of detail yet, but that would make me over-the-top excited for Bulldozer.

Base clock OC to 4.5Ghz+ ... and Turbo CORE enabled with a single core @ 5.5Ghz+.... *drools*

Every workload is different. It is not about being lightly loaded, it is about how much power the workload is consuming. You could have high utilization and low power.

For instance, we have an Opteron 4100 series platform from ZT systems that is at 100% utilization and only consuming 126W (2P @ 35W TDP each). The rest of the system is drawing more than 56W between memory, fans, power supply and drives, so that means there is still headroom in the processors.

Many workloads could be high utilization and still lower power consumption - it is all about how many transistors are firing based on the logic of the workload. If you have zero floating point you could be at 100% utilization and still have tons of headroom.
