He can never source it like his other assumption and claims.

Seeing how Nvidia is having yield issues, I doubt Nvidia will drop prices, beyond their MSRP. It's already a bigger chip.. And if you look at previous gen 390 and 380 cards they really didn't have much competition from Nvidia in terms of price.
Of course we never get told whether they are having yield issues (maybe the F's Edition thing is totally about milking customers).
But if they were, then while they are unlikely to drop the price on GTX1080, bad yields could imply that they have quite a lot of dies which failed at full spec and that they need to get rid of. Even more so if those harvested dies can't make GTX1070 specs either.
In other words, poor yields on GP104 could mean a surplus of GTX1060/GTX1060Ti.

One thing that hasn't been talked about much is AMD's relationship with Global Foundries. This is the first time AMD is making GPUs with their long standing partner Global Foundries (owners of GloFo own a 10% stake in AMD) I would not be surprised if AMD has more favorable wafer supply terms than Nvidia has with TSMC.
Not being made at TSMC is very important. A pity it took AMD ten years from when the merged with ATI. Even if AMD's and subsequently Global Fondries' process was never ideal for GPUs, having to pay penalties under the WSA was crazy. You would have though that rather than paying those they could have design some part to use up the wafers. And since GPUs are really parallel and since 'slow-and-wide' or 'narrow-and-fast' are both possible for GPUs I cannot see why they didn't do this years ago.

I do not believe Nvidia has Yield issues. It is more due to availability slots in manufacturing supply. Remember that TSMC not only produces chips for Nvidia but many, many other companies.

GloFo pretty much produces at this moment only for AMD.

Every new GPU has launch issues due to demand and other stock inventory. It takes around 2 months time to sort it out. Same will happen to Polaris.

The problem which you do not take into account is that GLoFO was producing chips for AMD for past 6 months.


AMD has to supply those chips not only to consumer market but also - to OEMs. We are talking about quantity going in millions of chips if we take account both mobile and desktop versions of Polaris 10 and 11. And as far as I know, AMD has 3 fabs to supply this from GloFo.

oo touchy.hit a nerve?*laughs*

Not in the slightest.

With all due respect, I am recommending the Oxford books for you because they are great starting points for people struggling with English. Take your sentence formation for example, "Oh, touchy. I hit a nerve?" would be the proper way to communicate your message. Remember, the impression you leave on others is entirely based on your capacity to type out proper sentences as well as your ability to read and comprehend information which is being communicated to you in text. This is a forum after all.

If you reply with sentences which indicate a complete lack of comprehending what is being communicated to you then you do come off as being an individual of limited intellectual capabilities. I am certain that this is not true which is why I politely suggested the Oxford English lineup for your viewing pleasure.

These books should help you master the English language and thus add an aura of professionalism to your posts.

Why don't you take that to PM? Shaming members across the forum we will not tolerate. I consider your post to be offensive.

If you cannot source your claim then it considered as BS do you know that?

Ummm. No. That is what 1060/Ti is for.
Been suspecting for a while now that Polaris is meant to compete with GP106. Not GP104. That will be what Vega is for IMHO.

Point being, the value associated with the 480 is still intact at its price point. If you want 1070 performance at stock clocks (with OC headroom) then the 1070 is still the way to go.

I'm guessing i've left an impression on you.*laughs again*.




This is the third post where you are baiting/trolling mahigan to respond.

Stop it.

I agree, it should have happened eons ago, but I think it was due to process issues. They probably looked at Llano and decided there is no way we can have GPUs built on 32nm. And it was a correct move in terms of staying competitive in the GPU market.

Now that GloFo licenses Samsung's fab process.. the time was right to move to GloFo.

Agreed. I understand that the first wave of GCN products may have been developed before the merger was finalized, but the fact that Tonga and Fiji were still on TSMC was completely inexplicable.

After reading last few pages I come to conclusion that people on forums are not really interested in technology but cheerleading their favorite brands, and/or bashing the other one brand based on personal preferences.

People who are really interested in technology can be counted in single digits on this forum.

Not sure if they pay less for wafers. The use them or pay anyways agreement I'm sure plays a role in the pricing structure. I'd imagine GloFo is obligated too fulfill it's end of the agreement as is AMD.

Right I believe AMD gets dinged if they don't order a minimum required number of wafers, but provided the demand is high enough and they can satisfy this requirement, I would not be surprised price per wafer is more favorable than with TSMC.

So it's in AMD's interest to have a high demand, meaning be disruptive in the market with their GPUs.

I do not have time to search and quote you ,however, i remember you clearly said that AMD always launch new node GPU first and they will do same again.

What Nvidia beat AMD to 14nm. Please link a source or stop spreading FUD.

Can't wait for NDA to lift. Seems like Polaris might be a winner for a lot of the market.

That's true of the 32nm process used for Bulldozer/Piledriver, but the 28SHP process used for Kaveri and Puma+ works fine with iGPUs. No reason it couldn't have worked with dGPUs like Tonga and Fiji as well. It's not as if those two were speed demons on TSMC process either (they had lower max clocks than the GCN 1.0 products).

Indeed, last few pages are a really sad reading. I seriously hope moderators will bring down the banhammer and clean this place up, when the discussion sticks to technology this forum is awesome.

Price is "normal" for 300mm2 wafer for 14 nm process. Generally you do not see huge increase in cost of chip despite cost of wafer went up 4-2.5 times, compared to 28 nm, depending on volume of wafers sold.

Apple for example buys single A9 chip from TSMC for 47$, and they get around 450 chips from single wafer, if I remember correctly.

So the wafer is sold for around 20K.
The same price should be for AMD from GloFo.

Yeah, perhaps the advantage of 28SHP wasn't big enough to justify a redesign for the new process. AMD also didn't pull a Maxwell type optimization on TSMCs 28nm process. They were probably busy with HBM and Polaris and Zen.. they also don't have unlimited resources.

Umm... I think AMD are pretty much confirmed dominance with Vega 10/11 now.

If a Polaris 10 can match a 1070 due to this massive overclocking headroom while still running lower clocks than the 1070 then we have confirmation that the performance per clk figures of AMDs Polaris and Vega cards are much higher than those of nVIDIAs Pascal cards.

You have efficiency (lower than 150 Watts) for the RX 480 and then you can boost it to 1500MHz+ if you want... all for a card which is priced quite competitively.

nVIDIA will have their 1060 ready for around the same time AMD release their Vega lineup.

Seems to me that the only market nVIDIA are left with is the ultra highend with their 1080 for now. I am also willing to bet that the RX 480 will be available in massive numbers on launch day compared to the rather hard to find 1070/1080s.

nVIDIA appears to have known what AMD were up too and released their cards prior to having adequate supply (hence the founders tax). No wonder AMDs stock is rising exponentially. Their upcoming CPU and GPU products and VERY compelling and so far the rumors appear to ALL be true.

Nothing points to that. Polaris 10 got an official AMD VR score of 6.3. That's around what an R9 290 gives. RX 470 cant even reach minimum VR specs.

Even if you OC Polaris from 1266Mhz to 1500Mhz. We talk 390X performance in VR measurement.

VR was another part they would dominate, right?



And those yields didn't work out either...

If i can believe the posters here, for 1080p, 4GB should be more then enough memory. But 4GB would be used by FUD critics as if the RX 480 is a weak card because of having only 4GB of memory. I think it is a push for 8GB to make sure as much as possible customers will have 8GB of video memory.

Here is what i have been thinking about :
On one end, it is a marketing decision.
On the other end, having 8GB is a great way to load up all textures. What i have also been thinking about is that GCN might love lot of memory. Since it is all asynchronous and very fine grained, the CU that are idle can do preliminary work on data while not needing it directly and store it in the GPU memory when needed. Of course, this will depend on good drivers. Lot of ram allows for much more preliminary work to be done, aka scratchpad calculations and more. Something game engine developers can take advantage of with the low level API of DX12 and vulkan.

When looking at the polaris 10 chip, there is no difference for the GPU if there is 4 or 8GB. Both have the same 256 bit datapath. But 4GB would artificially limit the card for future purposes.
Also, it is good for the memory chip manufacturers. For they made a contract with AMD to sell as much 8GB chips as possible. Seems to me that some good contracts have been signed.

Where is "dominate" coming from? I believe what AMD said was that they planned to make VR capable video cards "affordable". If the 480 meets minimum VR specs and sells between $200-$300 then mission accomplished.

If they release a Founder's Edition with 1700 mhz boost assured under water for $300 I'll be satisfied. Anything less than a 1750 mhz boost is pretty bad at this point. I'm expecting 1800 mhz boost out of the RX480 Founder's Edition.

Why would AMD release a "Founder's Edition"? Nvidia term NOT AMD.
