Ohhhh. I missed that bit of context Cheers.

Well Llano and Bobcat did great . Only fail was bulldozer,so 2 out of 3 which is not bad.

AMD took a big fat writedown on Llano inventory in Q3 because nobody wanted it.

That's 1/3.

Wow we are talking about the 2011 here and you bring up a write off from 2012 when Trinity has hit the street. Seriously Shintai?

The single biggest factor for this sudden change in fortunes is a $100M inventory write-down AMD had to take this quarter for unsold Llano inventory. In Q3 of 2011 Llano was the biggest factor in AMD turning a profit, but a year later those chips have been superseded by AMD’s new Trinity APU. Notably AMD is calling this a write-down and not a write-off, so it looks like they’re accounting for the loss of value of these APUs (i.e. they’ll have to sell them at lower prices than they planned for), as opposed to simply throwing out $100M in Llano APUs

I made a statement in April 2011. In 2011 Llano was a great seller for AMD making them turn a profit like AT writes . Next year you have to account for much better product called Trinity and hence write-down.
Also back then Witchita was still on the roadmap and they didn't yet axe it. Nevertheless a worse product than later cancelled Witchita ,40nm Bobcat(Ontario) , was the one that brought them most money besides the desktop segment :

AMD doesn’t completely break down their CPU revenue by processor line, but they have stated a few facts. For client revenue (i.e. non-server) desktops were cited as being especially hard hit by lower sales volumes and ASPs. As for notebooks, AMD has stated that Trinity’s share of AMD notebook shipments has just surpassed 30%, which implies that the majority of AMD’s notebook APUs are still Brazos and Llano.

PS I knew who will come out of the woods to defend thewho . No surprises there lol. BTW If you haven't noticed,posts by Francois are gone from this thread . I wonder why...

Those numbers actually make sense to me. Looking at the Wikipedia page for Super PI:

Super PI utilizes x87 floating point instructions. These instructions have been superseded by 3DNow! and Streaming SIMD Extensions.

The other thing to know about Haswell is that they replaced one FPU addition unit with a FMA (Fused Multiply-Add) unit. This unit can be used to perform additions as well, but it takes longer to do so, and code must be recompiled or rewritten to use the FMA unit to do additions.

I don't know about wprime for sure, but it appears to use the same type of code. So I'm impressed that Haswell is as close to Ivy as it is on this type of benchmark. And I'll be waiting for an integer benchmark to really rate its performance.

That is "thewho" now infamous intel employee . He was active during conroe and penryn launches,posting on various forums and getting into fights with other forum users. Not a best way to represent intel IMO. Their CPUs rock'n'roll ,they don't need a fanatical guy to belittle and personally attack other forumers who have a different opinion than him. Just my 2 cents.

Also it's worth saying he probably tells the truth there and Haswell is just fine.

It was more the other way around. People were attacking him.

Conroe was coming out at the height of AMD dominance. Nobody wanted to believe "some Intel employee" that Core 2 was about to decimate.

If they wrote off so much llano inventory and no one wants it then why cant I buy an A8 for $40?

 

[Piroko]

From a financial standpoint it can be better to not sell part of your inventory and keep the selling price higher in the long run. But I don't know if that happened with Llano or if they managed to sell them off over time for (lower than expected, but still) stable prices.

 

[BrightCandle]

Over at Fudzilla (http://www.fudzilla.com/home/item/30339-core-i7-4765t-is-35w-quad-haswell) the news is that Haswell at 35W will have very similar clock speeds to Ivy Bridge and the 45W part will also be very similar to the clock speed of the Ivy 45W part.

They might get the power consumption at idle down but this doesn't look like good news for getting Haswell into tablets and increasing the overclocking. Fudzilla and S/A are far from decent sources of course.

If they sold an A8 for $40 they'd be taking a loss on the sale. Remember AMD doesn't get the $40 you pay, they get maybe 60% or 70% of that. Then you fator in their distribution costs, SG&A, let alone packaging and validation/binning (ex-fab) expenses. And you haven't factored in fab production costs (say $10/chip) and amortization of the R&D that went into the developing the chip...a $40 ASP would probably be a significant loss.

I'd be more interested in seeing some power consumption benchmarks from the mobile Haswell CPUs. I think that's the only scenario where Haswell possibly might shine.

I look at Haswell and what it carries. I would say your vision is short sighted / Haswell is a cpu that will improve with time. As more programms are compliled for all the new instructions. in haswell. Haswell is as close to being future proof as any CPU ever created. Its a cpu that will improve with time like a fine wine.

 

[Piroko]

Doesn't Bulldozer/Piledriver already have the AVX implementation which Haswell will get?

By the time SW has been updated to use the new instructions I will probably already have moved on to Skylake/Skymont or whatever.

 

[Ferzerp]

You're thinking FMA3 which addresses a = b*c+d (where the result must be stored over top of either b,c, or d) problems in a single instruction (and only that)

AVX2 encompasses that, but that singular operation is just a small, small subset of AVX2

 

[ShintaiDK]

Doesn't Bulldozer/Piledriver already have the AVX implementation which Haswell will get?

No. BD/PD (And SB/IB for that matter) got AVX1 and 128bit execution width. Haswell got AVX2 and 256bit execution width. In that matter, Haswell is abit liek Conroe. Offering singlecycle operations again.

 

[Haserath]

Doesn't Bulldozer/Piledriver already have the AVX implementation which Haswell will get?

No. Both Ivy Bridge and Piledriver have AVX.

Haswell will also have AVX2.

Piledriver does have FMA4 while Haswell will have FMA3.

 

[Ferzerp]

Piledriver does have FMA4 while Haswell will have FMA3.

Of note, what the 4 in FMA 4 means is that 4 registers are in play, so when you do the multiply+add, you can store the result in a new location without overwriting one of your initial 3 values.

 

[piesquared]

Haswell will also have AVX2.

Piledriver has AVX, FMA4 and FMA3, it's instruction set is the most advanced of any x86 processor. Kaveri will have AVX2 and will hit the market at about the same time as anyone starts using AVX2, so no advantage there for haswell there either.

 

[Ferzerp]

You never stop do you?

 

[piesquared]

You never stop do you?

aww what's wrong did I rain on your parade? I'll say it again then, Piledriver has both FMA3 and FMA4.

[edit]
And why didn't you correct the post you quoted?? Did you not know Piledriver has FMA3 and FMA4?

 

[Ferzerp]

That isn't what you said. You specifically tried to be inflamatory and start with your bizarre anti-intel pro-amd rhetoric.

We've already stated the same facts that you have. You try to turn every thread in to a promote AMD, bash Intel thread. It is old, and luckily, the mods appear to have lost their patience for it.

 

[Maragark]

You never stop do you?

Does the fact that PD has AVX, FMA4 and FMA3 offend you or something?

 

[R0H1T]

What's the point, its not like Intel's (r)evolutionary instruction sets are gonna make any material difference in the end ?

/quicksync anyone :hmm:

Naw, you try to turn any post that has anything positive about AMD into an attack on the poster as being an AMD fanboy. That's what is getting old. But you're just an intel fanboy, so that's not really surprising. There's nothing inflammatory about my post, but your bias is.

 

[Makaveli]

Ferzerp don't waste your time let them dance with someone else.

And in fact this thread should be closed no one has actual haswell data they can share without breaking an NDA.

This is just gonna turn into troll bait!
