AMD CPU speculation... and expert conjecture

[8350rocks]

According to the links given before Nvidia has been negotiating with Samsung and others but the negotiation failed. Apple and others are also in the target, but it seems that Nvidia got previous agreements with those are not in the patent complaint.

I find funny that some people that says me that AMD is needed to give competition to Intel in CPUs at the other hand expect see Nvidia to die. I never understood this double standards. We need both AMD and Nvidia, because their competition brings evolution and improvements. a world with only Intel is so boring and expensive as a world with only AMD.

Also I like to remark that Tegra is currently an important part of Nvidia business. Nvidia sell millions Tegra per quarter:

Tegra business is still growing strongly for NVIDIA. Tegra revenue was up 14% from Q1 2015, and 200% from Q2 2014 with a total revenue of $159 million for the quarter. Tegra continues to have strong demand in the automotive infotainment sector, with a 74% growth in that market year-over-year. This could be a lucrative market, with automotive systems generally locking in for at least several years compared to the mobile sector which might see a product replaced in less than a single year. The Tegra K1 has j

Nvidia has announced several HPC/server ARM-based hardware. No sure why the myth that ARM servers are targeted toward microservers continuer alive in this thread. Specially when some of the announced ARM servers are so powerful like E5 Xeons.

In fact AMD Seattle is for microservers but K12 is not.

About the idea that Xeon Phi running x86 code I want to add that ordinary x86 code will run slower and recompilation will only help in some cases. In most cases obtaining performance from Phi implies rewrite of the code and the use of AVX extensions. The "it runs x86" is marketing motto.

Juan, Kinda off topic. Is there any solid information that AMD is going 14nm for the new cores, or is it just logic that they would considering the time frame?

They will land somewhere between ~12-16nm

funny a lot of you folks keep mentioning HSA. AMD can't even put Dynamic VSYNC in its graphics drivers. speculate if you will but please do not lose touch of reality here.

They still don't have that i use that for ALL my games when i saw adaptive v-sync and read about it i was happy i usually just leave V-sync off. Edit just get RadeonPro

already have radeonpro. without it my 280x is broken. AMD should be paying the radeonpro guys millions imho. going back to the maximumpc interview with the nvidia guys (in answer to huddy), AMD creates new technology, make it open, then "HOPE" someone will fix it for them, much like HSA.

As opposed to Nvidia putting out a bloated driver package with TONS of extra software (reminiscent of windows in the early days). Then, also having their own driver problems in recent times on top of all that.

At least the AMD drivers have gotten much better, Nvidia drivers are getting worse.

otoh this means that amd has decided to 'ignore' desktop for the time being

AMD is most certainly NOT ignoring desktop for the time being...

Now now, you can just install the graphics driver stand alone. And again, most devs feel that even a hundred MB isn't that big anymore, even for driver control SW. Space really isn't a primary concern anymore; functionality is.

JEDEC Publishes Wide IO 2 Mobile DRAM Standard

[anxiousinfusion]

In any case... Now that the DDR4 train has started moving officially, I really hope AMD brings some news soon about a new socket for the APUs.

The speed for DDR4 are going up really fast and that's a good thing, I guess.

If they announce a new socket, they would need to change the package, right? Or they could have the same 938 pin socket config, but with a different layout? AM3++? haha.

Cheers!

I was really sad to see the X99 platform delayed to September but it looks like DDR4 prices/development are coming along regardless.

Troll taken care of. As always the best response to a troll is ignoring them and simply clicking the report button. Mods can nuke their posts but if you start quoting them then it becomes a bit of a hassle to remove. Trolls exist to incite people and cause strife, quoting them only spreads their words further and makes the problem worse.

AMD releases C++ AMP compiler in conjunction with MS and Linux to support LLVM and Clang w/HSA support:

http://www.amd.com/en-us/press-releases/Pages/developer-language-2014aug26.aspx?cmpid=social_20140826_30456596

Not sure if anyone had posted that, but AMD working with MS to produce a compiler for windows and linux that will do much of the work for HSA for you is a good step in the right direction.

AMD CEO Says More Time Needed Before New Chips Bolster Sales
http://www.bloomberg.com/news/2014-09-04/amd-ceo-says-company-faces-bumps-in-road-before-new-chips-help.html
18 months of old tech before new chips come out. i'm guessing he's hinting at k12 and zen.

 

[esrever]

Hes just saying on excavator on AM3 either. Kind of makes me said and also am going to lower my expectations for excavator and carizo.

Nice to see people discussing links with material discussed before here

http://www.tomshardware.co.uk/forum/352312-28-steamroller-speculation-expert-conjecture/page-314#14112611

As I said then the 18 months are for K12, because the architecture appears in AMD roadmaps scheduled for 2016. The roadmap was also given before, but in another post.

I want to add that the roadmap that I gave before has been confirmed by someone who has access to an official OEM roadmap. The difference is that my roadmap is lacking some new products scheduled for the future and that AMD has not still announced.

 

[8350rocks]

Yes juan, your roadmap is missing (redacted) and (redacted). Which are the 2 main pieces I am aware of for the new uarches. For what it is worth, though, your roadmap is also missing one codename I am aware of that pertains to excavator that is yet unannounced as well. Not sure when that announcement is coming though.

 

[gamerk316]

Oh, a lot of information you certainly did not expose to us there.

This is a bigger news than we might be giving it credit for.

Like I said, 64 bits computing was a thing thanks to MS more than AMD itself. So, now HSA might be a "thing" thanks to MS once again. The added bonus of HSA in Linux through LLVM is just added icing on the cake.

This is the kind of things that actually make me a believer, haha.

Cheers!

Indeed, the fact that MS helped write their compiler for windows should improve the optimization for their hardware, and also improve the performance of HSA related apps in windows.

AMD has just given a talk (Deutsche Bank Technology Conference) with Rory Read confirming that the sister core to K12 is named Zen as I posted here about a month ago

http://www.tomshardware.co.uk/forum/352312-28-steamroller-speculation-expert-conjecture/page-305#13942948

Rory also mentioned that Zen will be released in 2016 alongside its sister K12.

The funny thing is that I have been using the codename Zen in other forums as well and in one of those forums certain individual (who claims to have internal info) said me:

I'm sorry everyone keeps mentioning a non existent CPU core and it's rather pathetic seeing everyone believing that it's real. No such thing as a "Zen" core not really sure how to say this but AMD's K12-x86 core is NOT called Zen.

I knew about Zen back in June after the conference @ Austin...

Not much of a secret as it originated from an AMD employees LinkedIn profile.

Lok another article that proves PC gaming is on a rise!!!

Some interesting thoughts from Rory Read conference:

• 
  ■PC market is in decline, AMD lose lots of money with notebooks, and AMD is moving away to new markets
  ■TSMC 16FF+ is currently the preferred node for next gen K12/Zen
  ■28nm has excellent yields and will be used for a long time.
  ■Efficiency is a key parameter for new AMD designs
  ■AMD want to the a leader in ARM architecture, not in x86. Of course, Rory knows that Zen will not be faster than Skylake.

 

[juanrga]

And finally I want to mention that some of us knew of the existence of Zen since MAY, concretely the day 8.

1. Its important to remember that its the PC market in general not the gaming market as facts prove, its also important to remember that Amd is losing so much money over having noncompetitive products
2. its also important to remember that Amd will never be number 1 in sales in X86 over heavy competition with Intel forcing them to compete in lower markets

well i believe we have hundreds of thousands of moba players would like to disagree (and probably millions in china alone).. AMD missed the boat with LoL and Dota. their APUs have a monopoly for MOBA capable notebooks (which they are not aware for some reason) and you don't see 1 marketing push from them stating this. imagine if they actually partnered with Riot or Valve both in marketing and R&D. we could've seen HSA enabled source2 (source2 is out for dota2 by the way) or "source2 powered by Mantle ™" (patent pending). or at least offer "rares" & "legendaries" when you buy an AMD apu.

they gave up on the market where they can actually fight intel, shame that their marketing monkeys can't use their phd's to good use.
