TDP is going to matter alot i think
look at 2 BD products with the same TDP range, and the same number of cores, but have different clock rates. since TDP is what determines max turbo for BD, the question will be if the more expensive CPU is more efficient and able to turbo farther. OR is the cheaper cpu artificially limited a few TDP less so that it simply cannot match

[zir_blazer]

You're missing the point though. Sure, overclocked performance matters to most (but not all) of us here, but we as an overclocking community might account for what...10, 1K trays of CPUs?

Hopefully the extreme overclocking market stays that way and never get enough strength to drive the market. I have seen too many single minded people that just pays attention to ultra high end overclocked performance disregarding power consumption, price performance, performance per Watt, noise, etc. For Benchmarkings it may be fine, but with that ideology we could as well still be in the NetBurst era and sitting in Tejas successor.

Overclocking is a bonus that is nice for casual and even 24/7 usage when you're getting it for free, using retail heatsink and such. That changes when people is purchasing 50U$D+ heatsinks, 150U$D+ Power Supplies and the like, because they want to push a Chip much beyond the point where the Frequency/Voltage curve becomes exponencial and they get astronominal increases in power consumption and possibily noise for just 100 MHz increments, add in the diminishing returns and the exponencial Hardware price increase and you get a clearer picture.
The value overclocker, that is possibily the most abundant one, can't and doesn't have any real reason to push Hardware beyond that curve because the cost is not worth it and these days with a budget but well choosen machine you can't be really pushed by Software where overclocking further could make a difference bewthem usable or a PowerPoint slideshow. If you ask me, I would use the overclocking headroom to reducer Voltage and get lower power consumption and noise, and currently, for the vast majority of the enthusiast that is happily served by retail performance doing that should make more sense that the "how high it overclocks?" trash.

Haha, hang in there JF-AMD, the launch is near

Looks like JF is getting quite a lot of "spam" asking him about Bulldozer
I hope he isn't quite mad about it

I dunno, TDP might only be 100w but since its more than 95w they have to label it 125 'cuz thats how dey roll?

Look at the (rediculous) Phenom II X4 Black Edition lineup. 955 generally consumes less than 965, 65 less than 70, 70 less than 75, 75 less than 80...

thats the problem. its advertized at 125w, but is really using 100w

the turbo is the main question here, since these chips can OC with all cores running, its limit will be based on TDP. the advertised TDP is either going to be used, or its going to be a lie.

love how that dude is like "OMGZ ONLY 30% LOADS" when most of the stress is on gpu (unless it was made by treyarch)

[undone]

Well,

The latency results for simple sequental access show that prefetching is disabled in this ES....

In Sandy Bridge preftching reduces the L3 latency by a factor 2 or so. Latency reduction
is responsible for most of Sandy Bridge's IPC increase over Nehalem.

Regards, Hans

Looks like we can see huge boost when comes to retail chips.

Is press NDA coming off today?

[freeloader]

Is press NDA coming off today?

Most places I've read say the 6th or the 19th. I hope it's tomorrow.

[EniGmA1987]

I thought someone said it was the 9th? :p


I dont think anyone really knows when it is.

[JumpingJack]

Is press NDA coming off today?

It maybe that the NDA press briefing is on the 6th with the NDA lift for the 19th. Thatwould make roughly 2 weeks between briefing and launch, which would sound about right.

[PatRaceTin]

i hope to see it on the shelf this month

[Blacklash]

that's what jf said and it is not hard to get.

I completely agree that it shouldn't be hard to grasp, and comments I've been seeing in BD threads on various forums suggest some are certainly having trouble with it.

I really hope it's september so it's possible to see how bf3 runs on it.

[2good4you]

At first glance the longer pipeline and higher Frequencies makes Bulldozer sound like a NetBurst inspired thing with lower IPC that current K10 that could be as big as a fail as Prescott was, hot and ugly. If wasn't because JF-AMD insistense on the "IPC increases" topic (Refer to Hans de Vries signature ), I would be dubious about what the hell Bulldozer is. But that very JF-AMD statement, plus the fact that the current trend on performance per Watt means that no one sane enough would design anything like Prescott, makes me believe that Bulldozer could end being quite... Interesing.
At the bare least you have a bit higher performance per clock, and you also have a bit higher Frequencies. Even if it doesn't beat Sandy Bridge it will come dangerously close.

Its far more complicated than that. Read my Bulldozer preinfo thread at sweclockers and use translator. Yes indeed, it,s a deep piped microarchitecture but very efficient. With it, s module structure allowing the whole front-end and L2 feed one core, IPC will be higher. the branchpredictor and fetch unit is far more accurate and powerful. With Turbo and all other improvements like new IMC and so on, I think you should be ready for some impressive performance in all aspects.

Its Monday.
Monday's not good for me

[FlanK3r]

Hope, it will be really soon!

Cant you even say when NDA is up?

[Particle]

Not usually. The expiration date of NDAs of this type are generally themselves under NDA.

i think the date isnt even listed since it would have to change with any delay. probably says "when we say you can"

[LowRun]

I'm starting to wonder if AMD knows the date

[JF-AMD]

So from this post what is the conclusion?
Well no benchmarks are release before launch because performance is not what expected it will only stall demand before even launch. Intel if they want now at a raise of a finger they release IB and SB-E in one month.
All the post sounds just like JF-AMD have smoke something.

After at least 3months of delay and some good lies on the way, you could tell to consumers: When we launch, we launch...

We have been saying no benchmarks until launch for the 5 years I have been with the company. I have said that on dozens of forums, including this one, for quite some time. It has nothing to do with the product but has everyting to do with disrupting business around our partners.

I don't smoke. However central texas is in flames right now from and there are hundreds of families that have lost everything. 2 of my friends from AMD lost it all with only moments to get out of the house. We're all a little sensitive to smoke now. I can smell it in our AC, it's so strong that it is not getting completely filtered out and I can see plumes on the horizon.

So pretty much what JF-AMD was saying. A lot of the ES chips have features disabled on purpose.

No ES chips have ever been crippled. They are not final products so they are not representative of final product. Pull a cake out of the oven halfway through the cooking and you'll not be real excited about a runny mess instead of a nice slice of cake.
