All of this talk about engineering samples is really annnoying because they are not designed around performance. So trying to measure something for performance when it is designed for validation is really pointless.
One could say it is more annoying that AMD isn't doing anything to quash the results of ES, if the ES samples are so bad performance wise.Quote:

Marketing 101, if you see your #1 product getting butchered, it is time to trickle out more info to combat the misinformation on the purpose of ES samples.
It would also be nice to know what the current stepping of BD is, compared to the ES samples.
Kobaltrock,
hate to break it to you but 99% of AMD's revenue doesn't come from overclocking folks or categorical "enthusiasts." It comes from integrators (HP, Dell, etc.) who, as JF-AMD noted above, test based on qualification, etc, not on supposed gross performance. edge-cases always emerge (e.g. the development of a particular line of systems) where performance matters but you'll typically note those are introduced AFTER mainstream parts...
so, AMD doesn't need to waste marketing dollars on folks who build use cases around stuff that XS tests....they need to spend the time on revenuing systems and integrators.
cheers,
Dave
FYI,gimped B0 ES videos on youtube are gone.So they are doing something about it.Quote:

While Intel would continue to capture more market in the low-threaded segment such as gamers, certain benchers, and office/home users.
I don't really see a problem with this. Having choices is good. No one processor is going to effectively process all types of code.
xtremely true. back when all you had was one core and a set mhz/ghz, there was only 1 task, be as fast as possibleQuote:

thanks to turbo and power gating, you can blur the lines a little, but no chip yet has the ability to offer all of those by adjusting a setting in the bios
I think what JF is trying to say is "the cake is a lie" =D Especially the one OBR is regurgitating.Quote:

AMD wont, hasn't and has lost significant market share for nearly 7 years being second fiddle with slower parts. So far, AMD has lost on all those market segments you talk about. Again, they will never take back any market share with what I see so far.Quote:

Sad fact is, AMD is having more issues gaining Market share due to other factors. Like Software Company requirements that say "Intel blah blah or higher" on the requiremnet specs. I never see AMD bosted on the top of the Specs sheets. You sometimes see "or Equivalent" which basically means the competitors option (AMD). And companies like mine where we blindly used Intel regarless of the perfomrnces at any price point. Even when AMD had the clearer Choice all around, They couldn't cut the market share due to these factors.Quote:

CPU manufacturers had to decide if they were going to keep their chips scalar and just make those execution units faster or if they were going superscalar and add redundant execution units. Obviously the later course has won historically for general purpose cpus. But they can't go wild adding tons of redundant units because there are limitations and you get diminishing returns. Sometimes there simply is only so much instruction level parallelism (ILP) to be extracted from any given segment of code. It also takes quite a bit of extra silicon to calculate dependencies and it increases rapidly with the number of extra units.
Instead of fighting a game of diminishing returns with Intel to extract maximum ILP, it seems that AMD is simply refocusing on thread level parallelism. Even Intel with their renowned branch prediction, OoO engine, hyperthreading, etc still has execution units idle for a significant portion of time. So AMD removed one of the ALUs and all of the expensive logic required to check dependencies. They can use that freed transistor/power budget on branch prediction, cache, etc to keep the remaining units fed. IPC could still increase despite being less superscalar than their previous arch and the upshot is that the previously redundant execution units are freed to work on separate threads.
I think both AMD and Intel are working towards eager execution. In essence, instead of trying to predict which path to take when you come to a branch, take both. IMO, this is the next leap both companies need to take in single threaded performance. Bulldozer would give AMD a significant lead on developing this, IMO.
For one thing, AMD didn't make much of a dent in Intel market share even when they did have the faster chip in both single and multi threaded apps. So there is indeed more going on than simply who has the faster chip for any given application.Quote:

But if they do have the better multi-threaded performance I expect that they will regain ground in the segments I mentioned, or at least the server segment. Single thread performance doesn't mean much of anything in the server world. What matters is total throughput and power consumption while doing it. Why do you think the market was salivating at the thought of clustered ARM chips for server applications?
hi guys i dont post here much but have been sneeking around the BD threads and this delay has got me wondering..... this is just a thought btw, at the moment i dont know what is going on.... its delayed , its not delayed , needs a respin for a higher clock blah! blah! blah!
do you guys think there is a possibilty that amd delayed zambezi because the enhanced/next gen BD cores trinity uses offers better performance? they have clearly been testing trinity for a while so would it possible for this new core/cores to be a replacement for the first gen ones but obviously without the gpu part?
i may be mad but it was just a thought
Few things.
Some people suggested that BIOS maybe the issue.
Well, boards are final and shipping, nobody in their right mind would ship a board to OEMs and even retail, with a claim about AM3+ compatibility if they would REQUIRE a bios flash after the client gets it.
JF insists that they dont cripple ES.
JF u sure ? Cause that doesnt tell a good story.
Because well, if bios aint broken, and the chip isnt.Its just BAD.
I know, u take as many chips as possible to get ES`s ,so clock wise, they can be very different from final product.
But they should perform clock for clock rather same.
Up until now, all ES`s ive seen had clock for clock very similar performance as the final product.
There were many issues, like low clocks, high volts, high TDP etc etc.But performance wasnt that drastically different.
And you say that AMD has only some basic idea about CPU performance before production ?!
Dont you guys simulate all the logic on these fancy hardware simulators big as hell which can simulate any processor albeit at MUCH lower speeds ?
And shouldnt you know your IPC targets for different workloads when the cpu is still on paper ?
Youre claims are kind of alarming.
@RussC
The thing is, in this day, pure performance doesnt really matter to the 80% of population.
"good enough" is the mantra for todays computing.
And even NOT good enough atom made a killing.
And now AMD makes a killing with zacate.
Simple example, if i offer my girlfriend a new laptop with sandybridge, which will be too slow to play sims 3 without choking, shes not going to be happy.If Llano will do that, shes going to opt for that.
And it doesnt matter that some tasks that she rarely does are going to be slower.Because gaming NEEDS some kind of performance, but with encoding a movie clip she an wait a minute instead of 30secs.
Llano will do good too.Although it needs cpu part to be revamped, but its coming next year.
Only problems may be with desktop/server part as we dont have BD numbers yet.
@Informal
Are there any pics of B1 in action from obr ? i cant find it.
@Jazkat
Trinity uses BD v1 .So the same arch as coming BD for am3+.
@ XLR8
well from everything i have been reading trinity uses a enhanced , next gen bulldozer core..... wouldnt that mean a different one to zambezi?
"Trinity will utilize x86 cores based on improved Bulldozer micro-architecture as well as DirectX 11-class graphics engine" ?
AMD Financial Analyst Day 2010, revealed the 2nd generation is to be scheduled for 2012. AMD currently refers to this as Enhanced Bulldozer.?
Trinity is based on our [enhanced] x86 bulldozer core?
@Jazkat, seems youre right.
Ive read somewhere article aboud Llano and there was a part where they stated AMD is going to use in each generation cpu core from past strictly CPU generation cpus, like Llano does with stars currently.
Thats interesting that theyre accelerating that.
yes this is why i had that thought, i mean if they have a working enhanced BD core already maybe this is the real reason for the zambezi delay.Quote:

No matter when BD is released, I would expect Trinity to use an enhanced version of those cores since it comes out later.
A. I thought I already addressed ES on this forum, why are we still beating that dead horse?
B. I have said (in other places) that the delay is scheduling. Client moved from Q2-Q3 because of some re-scheduling, server is staying in Q3. If you want to read anything into that, you can see that there is not a huge amount of time difference between them, and the fact that server stays in Q3 should be an indicator that all of the rumors and speculation are massively overplayed.
JF: I think, its because higher priority for AMD is now Llano (notebooks), so one or two months sheduled of BD )in desktop) is nothing...I believe BD will be good :). 32nm capacity is maybe limited. When will be new FAB completed? Thx.
