From AT's article, this should be quite clear for anyone who has paid attention to AMD & Glofo for the past several years.



In the last financial, AMD had to pay GloFo for un-used wafers due to their contracts. With APUs not being able to keep up in volume, AMD needs dGPU chips being made from GloFo.

The question would be why they would source from TSMC..

With Samsung touting their alternate process, 14ff enhanced power node, clock speed or high TDP GPU is a non-issue.

Thus, the logical answer would be GloFo is incapable of producing a big die on 14ff with decent yields.

But why would TSMC be any better at it? There's rumbling from unhappy SOC customers that their small dies aren't yielding well on TSMC 16nm ff...

Add two together, the big-chip next-gen sounds like a long way away.

I think you had too much Samsung/GloFo KoolAid

Everyone in the industry is going towards TSMC for 16FF+. Its easy to see on the customer amounts. But it will be very obvious later in 2016.

IIRC, Apple was even approaching Samsung to produce chips because they were not happy with yields at TSMC, this was awhile ago last year.

A9X is TSMC only. A9 was supposed to be GloFo+Samsung. But ended up being Samsung+TSMC. A10 will be TSMC only using 16FF+(16FFC perhaps).

But look at it in a good way, this means higher end products wont be at a node disadvantage to NVidia. And you get higher performing AMD parts in the top.

Without the WSA, I doubt AMD would get all its chips made anywhere but TSMC.

And there's absolutely no politics involved at all in Apple wanting to direct custom away from Samsung? And we know how the processes compare across the whole range from mobile SoCs to 3GHz+ high end CPUs?

There are a ton of variables, and anyone who pretends to know what to expect is FUDing. Wait for the parts, wait for the data, and then we can argue to our hearts' content

Not really a head start, NVIDIA just hours ago just announced Drive PX 2 with two Pascal GPUs on board as well as two new Tegra chips...with Pascal GPUs integrated.
Yes, they announced PX 2 with two Pascal GPUs, but they shown a "PX 2" board with 2 GTX 980M attached in MXM slots

AMD shown a running prototype of their Polaris based card. It's been approved by AnandTech.

Their lineup desperately needs a low-end solution with a massive leap in efficiency.

The 950 and 960 are owning them, despite how strong the 380/X are in performance. For many systems, the power use of these GPUs, even the 370/X class is just too high and their only option is a 750Ti or 950/960. I know this first hand since I recently upgraded a friend's rig, some crap Dell thing with a 240W PSU that's really awful.

IF either AMD or NV release a huge chip on 14/16ff early, it would be the surprise. I think everyone understands how much more sensible it is to test the waters on an un-proven node tech with smaller chips. Certainly for consumer GPUs that do not enjoy the HPC $ margins.

The demoed Polaris, ~30W GPU with that kind of performance profile is absolutely a winner.
I think they aim with this chip is to dive into the "i have a cheapo psu, cant have more than 200w without PEG 6 pin" crowd" segment, both in prebuilt and DYI variants.

Which is quite alright considering cheapo, unbranded psu quality has dramatically fallen since the last decade.

I think 16ff+ will be used for the parts with more performance but lower volume. The rest could easily be made in 14LPP and reach the dreaded WSA goal.

Sorry, for derailing the head, but no. Apple and Samsung lately have much better relationship, more partner like, than competitor, and supplier at the same time.

Trying to keep a straight face here, but do you actually believe this?

Do you think if any of those companies could make the other one disappear they wouldn't do it instantly?

A gamer doesn't care about how much power it uses...it does not matter if the best AMD card used 1 watt of power, if the nvidia care used 250watt but was faster they will still get nvidia for games.

If that were true, then 290(x) and now 390(x) would greatly outsell GTX970 and 980. less true now but 1 year ago 290(x) was very cheap or very good price/performance.

Most people have no clue and just buy whatever "feels" better to them due to prior experience or another clueless guy recommending it.

Also these chips clearly are for mobile and hence power usage does matter a lot.

Or TSMC is just cheaper in total cost (actual process + designing for it).

Yes, I do. I use Apple hardware, my next computer will be Mac Pro with Broadwell EP CPU, and I am interested in Apple world, and what is going on in it.

I have right to say about this, that right now, Apple and Samsung are more like partners. IBM, AMD, Apple, Samsung, GloFo - those are connected companies that work together in some ways in this business.

It's just a typo in a RAM description.

Anyway "Catalyst" 16.10 is a build number (like 15.30 etc.), not a software package number (Year.Month)

With no relative useful info from Nvidia at their presser, this train is still on the rails!!!

I look forward to more info from RTG. I want to see what that chip can do uncapped.

Why do you dislike Samsung and GloFlo so much? Do you feel that they're just worse at making chips?

I see AMD still does not understand gamers. Hopefully that test was just to show power requirements and not a actual "we are better at gaming" test. A gamer doesn't care about how much power it uses...it does not matter if the best AMD card used 1 watt of power, if the nvidia care used 250watt but was faster they will still get nvidia for games.

AMD does this all the time, its all about saving power for them, or new technology that no one actually uses in real world.


Somewhere down the line they turned into the guy on the block that buys a Alienware computer and says its better than anyone else.

... I can't believe this post actually happened.

You can try dismiss the reality as much as you like. It got nothing to do with me no matter how hard you keep trying post after post. The customer portfolio says it along with the results.

It was a legimate question. Do you feel that going with them will ultimately hurt Polaris and leave it at a disadvantage?

Surely you're intelligent enough to realize "customer portfolio' is a function of many factors.

Come on man, show us the electrical data for your argument. Relying on inference to make your point is a very poor, if not ridiculous proof.

If you don't have anything definite, admit it.

Shintai, If the small Polaris is made on 14nm process from GloFo/Samsung, which according to your words is worse, and less efficient process, uses GDDR5 memory and is able to maintain 60 FPS in SW:BF in 1080p while using 3rd of the power required to do the same thing by GTX950 - it will be hell of a architecture.

And TSMC's process, if it is THAT better as you are trying to picture it, will bring even better chips.

We can only see when we can compare the 2. And when its tested by reviewers and not a PR setup

But non the less, performance/watt with the first node shrink in 4 years will be great.

glofo used to be part of AMD, so some folks do not like them. ALso people feel they are inferior because TSMC was bigger. Even if gloflo is doing good now, they can't get over it. Samsung is just getting hate because of association.
