Mushroomboy, I've been looking at your code in your signature, it looks all wrong to me!

int getRandomNumber()
{
return 4; // Chosen by random dice roll
} // guaranteed to be random.

this will only return 4 though correct?

lol

in getRandomNumber()
{
int nNum = 4;
Random(nNum); // 1-4 ?
}

or am I on the wrong planet here?

It's a joke.... That would be Sony's implementation of ECDSA: http://en.wikipedia.org/wiki/Elliptic_Curve_DSA

Sounds useful in an environment with standard motherboards that don't have OC features but sounds useless for the people who can overclock. I know my i7 950 overclocked and folding is taking a lot more power than its reference TDP.

All speculation, of course.


However, do you understand why I believeTurbo based on thermal is has some advantages over TDP? In theory, the CPU could run closer to the edge of stability rather than an defined TDP limit based on workload. Drop the temps.... better performance automatically.
Ducky, what AMD is trying to do is make TDP more accurate. Say for example you get a chip binned at 2.2ghz and 125 TDP, but it only usually consumes roughly 75 TDP on average. What this will do is boost the clock speed until 125 is reached (or in this case up to 95% of it). So, theoretically you could go up to 2.6, 2.9, 4.0 etc until the TDP is reached, regardless of what your CPU temp is. However, I think thats where the PowerCool or whatever it is comes into play; if the processor is reaching its thermal limit it will override the Turbo and clock it down a bit.

However, I think the point of what AMD is doing here is to deliver the maximum amount of performance for any given TDP, assuming that heat is not an issue.

You are on the wrong planet. This is copied from the hacker presentation where they cracked the Sony OS on the PS3, the joke being that they were supposed to assign a random number to a certain variable in an extremely important equation, but every single time it ended up being the same number.

500Mhz across 16 cores within TDP, that's not of any interest to an enthusiast? How high will that 500Mhz be when only 1 core is raised on a 4 core BD? Turbo core may not be any interest to an enthusiast per se, but it gives an indication of overclock performance.

As an example i'm currently runnning my Thuban on stock vcore @ 3.5Ghz with 4.2Ghz turbo core (three cores), so even my crappy old Thuban can do 1Ghz turbo on stock (standard turbo is 400Mhz). Imagine what BD will do.

No ones said you can't disable turbo core, you can on current mobos and I would imagine you will be able to on future ones. As said above, it gives an indication of overclockability. Stock setting benchmarks, which is what most reviews are based on, are going to go through the roof. Your average 1090T will do 4.4Ghz on air, so expect to see at least this figure on stock settings with 8 core BD running turbo up to TDP . The 99% (?) of people who don't overclock are going to be in a win win situation.

JF already confirmed that heat isn't an issue with ~max TDP on stock cooling - which I read as 'BD will run cool, which when combined with an aftermarket cooler will be capable of far exceeding TDP with higher vcore' so for us, business as usual, but with that promise of 500Mhz over 16 cores!

They put a 5% protective rail on the CPU, sounds like a Flux Capacitor Governor, lol, which prevents users from ever reaching the TDP, which isn't a bad thing, but definitely not coming off as 11.

Basically he found a cool way of rewording Turbo Core / Turbo Boost technology to give it a little more hype, it's nothing new however, sorry AMD, not impressed...

The ability to shut down power to unused cores, lowering power consumption, however, is new, and very nice, bravo AMD, or should I say Brazo? (The platform it was truly designed for?)

I think for the client Desktop computers, which tends to be bought more used by Enthusiast, programmers, etc, as most businesses are way to cheap to put in an 8 core system in an employees Desktop, let alone schools, this marketing isn't going to reach the lovers it should have been created for!

Enthusiast!

If the 50% rumored gain over the current Phenom II X6 & i7 950 is true, that's a decent gain, but definitely not the gain some of us were hoping for, then AMD may wrangle in a few enthusiast after all, power folders, Overclockers like us, etc..

Much yet remains to be seen about Bulldozer, let's just hope there aren't any major design flaws with the Main Boards like Sandy Bridge has presently.. (ouch!)

I'm leaning toward "hopeful" & "promising" with Bulldozer, but I'm not going to bet the farm on it, no way...

In a nutshell, what I'm really trying to say here is, nice read, but failed to reach the intended target, the Enthusiast, which are all about the clock speed, +500 MHz isn't something new and you are STILL holding the bag too tight, the cats inside are starting to scratch and claw (buying up Sandy Bridge), put up some real specs or zip it already!
Please, do tell us where all this resentment comes from. There's a lot of rage in your post and I would like to know why you're angry when the chips haven't even been released yet.

If 50% isn't enough do tell us how much you were expecting. Did you want AMD to increase throughput by 100%? If so I'd like you to tell us in which scenario you actually ever need so much memory bandwidth, that getting triple channel bandwidth with dual channel memory isn't sufficient for you.

500MHz+ Might not be enough for the enthusiast but a 16 core server chip going 500 over 'stock' speeds is wasted? Now imagine the next super computer with AMD 16 cores hitting more GFlops simply because of this new feature. Also you gladly forget we, the overclockers, are less than five percent of all computer users. Are you telling us all that a 500MHz boost for the normal buyer is nothing?

While businesses, schools and corporations won't buy 8-16 core CPU's for text processing they will buy them for virtualising their environments. While the average consumer won't buy a Compaq, Dell or HP with any more than two cores these CPU's will sell by the tens of thousands. This is where a lot of the money these companies make is and this is where they will concentrate a lot of their marketing and efforts. If I could I'd buy an 8 or 16 core and run Boinc on them.

The only disappointing thing here is your post. You haven't even bothered to read half the thread and yet you make wild claims. You have posted in other threads about this and still you ignore the fact that AMD have said that 50% increase equals triple channel. Now if you desperately need to get superior numbers in memory benchmarks you can always buy quad channel memory.

I am also excited and can't wait to see BD released. Thanks to Intel AMD wouldn't have worked so hard to come up with a competitive product. While nothing's proven yet there's no need to tear your hairs out and rant about something we actually know very little about.

Liranan, my point is, and I'm not holding resentment or raging, and yes I'm VERY aware about Bulldozer, also read the full article too...

I WANT SPECS.....

They are not releasing any NEW IMPORTANT INFORMATION...

Like I said, he is just restating what's already known, and trying to hype up turbo core.

Turbo Core IS NOT ALL THAT AND A BAG OF CHIPS, sorry....

+500 MHz = OLD NEWS....

I WANT NEW SPECS, that's what I'm saying in my post!

(did you hear that Intel Fan Bois?)

JF already confirmed that heat isn't an issue with ~max TDP on stock cooling - which I read as 'BD will run cool, which when combined with an aftermarket cooler will be capable of far exceeding TDP with higher vcore' so for us, business as usual, but with that promise of 500Mhz over 16 cores!
That's the server platform, and granted yes +500 MHz (or more if Overclocking) when using 16 cores would be like WOW, but Zambezi is 8 Core, not 16, nevertheless, not anything to sneeze at, it's nice!

I'm pretty sure Bulldozer will achieve great clock speeds on a stock fan or with an Aftermarket Cooler, as AMD stock coolers tend to be SIGNIFICANTLY better than Intel's thin POS which are godly annoying to put on a MB!

I have ALWAYS liked AMD, because of their Price, and IF Bulldozer / Zambezi specifically, isn't too expensive THIS is definitely going to be my next upgrade, not Sandy Bridge (which now has Sata Controller Issues, ouch!).

I want NEW STATS, they aren't saying anything till the release, which leads me to believe that, like it's name, will Bulldozer over previous CPUs! I'm not crossing my fingers, I'm very confident Bulldozer is "The One".

I'm just tired of old news, I WANT NEW INFORMATION/STATS NOW!

:-/ Not understanding something. I even read through the 98 posts debate and I'm sorta on Duckie's side.

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.

You have to understand that what JF-AMD Publishes is FOR the server market. He is the Server Guy; that is his territory at AMD.
He doesn't do things or think in a way that reflects what the consumer market wants.

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.
