AMD 20nm GPU Discussion Thread

I don't know if its to early to have this thread, but I think it would be good to get the ball rolling on what AMD has in store for the future.

There isn't much info on what AMD will be doing come NVIDIA's new node lineup. From my searching I wasn't able to find anything conclusive on what they will counter with.

So what say you? Will they release any truly new tech this year, or are they going to lag behind? Considering the rumoured parts shortage awhile ago, I have to wonder how robust the AMD manufacturing process is for the upcoming change in tech.
 
AMD has led NV, (by a fairly significant margin) for the last several nodes. I doubt 20nm will be any different.

Though, perhaps 16nm is the way forward.
 
It seems AMD got GCN 1.1 and nVidia Maxwell for 20nm.

But 20nm is Q4, so patience.

The part shortage was simply bad logistics. Nothing else.

I really hope not. That would mean 290X-power or less for the 380X or 390 and probably marginally-better-than 780 Ti average OC-power for the 390X. Meanwhile, the GM210 will be around 40-50% faster than the 390X. RIP competition. :/
 
20nm should be interesting because it's a chance for AMD to show off it's greatest skill: hardware design.

if AMD can produce a 500mm die, it wins. AMD has far better performance per mm2 than nvidia and the moment nvidia stops pumping out <550mm dies it loses because it doesn't have as good hardware design as AMD. It just has deep pockets. Which is a super power, according to Batman.

You should know what posts are garbage [redacted] by now. :awe:

Profanity isn't allowed in the technical forums. You should know that by now.

AMD has better perf/mm^2 for several reasons.

In GK110 nvidia has implemented its FP64 shaders separately which takes more die space (remember reading somewhere it was 60-80mm^2).

Nvidia makes a far greater share of their profit from professional products where the larger die cost can easily be absorbed.

If you look at GK106 vs. Pitcarin or GK104 vs. Tahiti the two are very similar from a perf/mm^2.

That said AMD GPU hardware is quite impressive.

GK104 has far better perf/mm^2 than Tahiti. GK106 and Pitcairn are roughly equal, and GK107 destroys everything in perf/mm^2 including anything GCN 1.1 (Bonaire and Hawaii).

But you are right about Nvidia's big die - it has never had great perf/mm^2 in graphics. Nvidia's R&D in GPU's is much higher than AMD's though, so it is highly unlikely AMD will ever go as big as Nvidia, especially given their perf/watt/mm^2 which is much higher with Hawaii than GK110.

"manufactures the design"? Do you know what manufacturing is

You want me to use synonyms?

- Not to nit-pick, but AMD manufactures the design but doesn't produce the design.
- Not to nit-pick, but AMD builds the design but doesn't produce the design.
- Not to nit-pick, but AMD fabricates the design but doesn't produce the design.

Not to pick my nose, but AMD designs the transistor layout. That is all. They do not manufacture the actual GPUs. That is all.
 
Wow. Just stop with the nit picking, you know what I meant. The manufacturing process regarding AMD's partners. Sheesh.
 
20nm is so much late to the race. I prefer this 20nm come late and 16nm-14nm FinFet ready by end of 2015, the performance jump will be bigger.

You mean AMD designs but don't manufactures the chips, no?

Nvidia doesn't have anything other than a press release at this point. They may have working silicon, but that doesn't change the fact that neither company will be releasing 20nm GPU's for months.

The Maxwell announcement was just well thought on PR in combination with the dx12/dx11 announcements they made purely with the purpose of PR crapping Mantle. Nvidia is so adept at PR trolling AMD people don't even notice it. AMD is so inept at PR they are unable to counter it.

I didn't think the parts shortage had anything to do with the actual GPU's, but the other parts on the PCB. Correct me if I'm wrong someone.
 
The entire internet is aflame with Maxwell hype. Nvidia is doing a damn good job of getting people excited.

And AMD is... where is AMD's Pirate Island PR? :|
 
In my opinion, what would kill if:

R9 390X -
4096 ALUs / 256 TMUs / 64 ROPs + 8 GHz (Effective to GDDR5)/ 1 GHz (Actual) 512-bit HBM - 4 GB.

FirePro W9200 -
4096 ALUs / 256 TMUs / 64 ROPs + 8 GHz (Effective to GDDR5)/ 1 GHz (Actual) 512-bit HBM - 16 GB.

I think people realize the marketing tricks Nvidia uses, at least I hope so. Naturally there are always some that eat up company propaganda willingly.

On 20nm AMD stuff, I believe they have said that tape-outs are occurring basically now. So that means somewhere around the end of the year, or could be 2015. Nvidia will likely be a bit later going by history.

1H 2014: AMD possibly tapes out 20nm GPU / SK Hynix gives HBM samples to partners *cough*AMDisone*cough*.

2H 2014: AMD starts 20nm GPU production / SK Hynix starts HBM production.

Coincidence?! I think not! Let the conversation BEGIN!

AMD has played their GPU cards close to the chest since the 4870 days, which has caught Nvidia off guard almost every time. They won't show off any 20nm press stuff until its so close to launching that the only thing Nvidia could do to respond would be price cuts.
 
While I expect an average card, I'm hoping for something awesome. If AMD could get poer down I would love to see a big die chip from them. Otherwise, go small! I think with maxwell being power efficient they will need to reduce power.
