You have deleted the quote and also the link. I will reintroduce the quote:

Dude, even I will admit that it seems Intel needs to admit defeat to ARM. 1.3GHz dual core A7 with Smartphone class TDP is beating 4 core 1.4-2.4GHz Bay Trail with Tablet class TDP. And that's "28nm" vs 22nm.

The IPC of the A7 is on par with Ivy Bridge parts! Clock that sucker to 3GHz and it'll have a no worry replacement for the Macbook Air line and threaten even with x86 emulation.

Evidently it is about __CPUs__ not about GPUs.



I am not sure what you pretend to say here. That a phone would run BF3 at the same graphical settings than a gaming PC or what?



The quote that I offered is important by two reasons. First, because closely reflects the situation and, second, because comes from a known Intel fan. This gives his quote some extra relevance.

The quote that you reproduce is from begginer99. I remain unsurprised that he tries to defend Intel. This is the same beginner99 that writes this kind of nonsense:

Because the 3 AMD Fanboys you see everywhere posting complete BS need to be kept in check so that users seeking advice won't buy a inferior product.

I really don't get them. either they are hardcore trolls just out to provoke (mabye same person?) or as misguided as religious extremists. Anyway they make 0 sense.

AMD is useless on desktop. You will get better performance from Intel in all price ranges.

You can find a reply to his nonsense/trolling/flaming here

Juanrga has his rose colored ARM glasses on. AMD is a chip vendor. If companies continue to want to buy Temash or follow on Jaguar based products you can bet they will keep making them. Clearly they will be making and tweaking Jaguar for at least the next 5 years as both Sony/Microsoft will be paying for multiple die shrinks over the life of the console.

Most companies aren't going to pull a 180 and switch to ARM just for a power savings. There has to be a lot more incentive than that. If they have 5+ years of development into an x86 platform they're not going to just switch. That is a huge undertaking. The growth may not be strong but as long as it's pulling in profit they will continue to make them. TI has some parts they've made for 20+ years, and they still make/sell them.

It is being explained in the quote. If the market changes and/or your product is not competitive you need to adapt. As the quote remarks Temash didn't win enough designs and its TDP was high when compared to the competition. AMD has opportunity to win market share by replacing Temash with ARM.



The above quote explaining why AMD will be replacing Temash by ARM is _not_ from mine, therefore my 'glasses' play no role.

I will give again the link

http://techreport.com/news/25461/report-amd-to-introduce-arm-based-tablet-chip-this-year

Now please explain us what colour are _his_ glasses and what colour are _Rory Read_ glasses.

NVidia has officially killed the "Tier 0" program that Origin PC took part in...

http://semiaccurate.com/2013/10/07/nvidias-program-get-oems-like-origin-pc-dump-amd-called-tier-0/

@juanrga:

Look, your "facts" come from marketing slides. You accuse me of being foolish for reading into leaks, and rumors; yet, here you are doing the same.

In other words..."Pot, this is kettle, how are you doing?"

It boils down to this, if you compare low power x86 to low power ARM, you end up with x86 wins raw compute, and ARM wins...well...power consumption.

Additionally, I have a contact at AMD, and I am not at liberty to discuss the things we've talked about. However, I have word that there will be "a suitable replacement in HEDT, AMD is not abandoning the market that FX occupies". So keep touting ARM as a world beater, when reality finally arrives, we will see what the facts really are about ARM.

I think you will see the majority here, who know what x86 can do, and have seen what ARM can do, will be on the mark.

Further discussion of ARM cores and ARM desktop, etc. should pretty well be closed with this post.

I don't think you're going to acknowledge people with expertise about the 2 uarch's, and we're not going to buy into the marketing hype. This is where the 2 trenches have been dug, and no side is relenting. Time to call it a day on the subject.

One last note:

AMD is a chip vendor, but they are not fools either. ARM tablets are the lion's share because android doesn't run on x86. So, in the world of tablets, you can either do windows tablets (epic fail) or join the android tablet crowd and produce some ARM tablets too.

This proves nothing about ARM being anything about the future. Additionally, Temash finds it's way into low power netbooks, and other devices that actually are a majority running x86 software.

The 2 are not dissimilar, however, they do not occupy the exact same space. Had windows tablets taken off like a rocket, all this mess about ARM wouldn't even be a conversation.
 


But that works both ways... The ARM platform being compared all the time, is a cellphone or a tablet at most.

I would put the ARM vs X86 argument in a bag for now, since neither camp (in favor or against) have an oranges to oranges test that no one can say "this doesn't fit". All theoretical arguments are destroyed with a "if cows could fly" and until AMD puts the SoC with an ARM CPU at a demo or something, we're wasting time IMO.

Cheers!

Great talk about why PCs are falling off...
 
if/when amd does launch a consumer arm tablet soc, it'll pop up on apple's radar. apple has been shifting it's soc business to tsmc which also makes amd's kabini socs and nvidia's tegra socs and gpus. apple could monopolize (or attempt) tsmc's 20nm and smaller nodes and lock out both amd and nvidia. then the other option would be glofo, who has laughably bad track record (i don't buy their promo slides).

You already tried this kind of argument before. My correction is the same than then.



Another repetition of misguided claims. Again my corrections are the same than then.



If you continue misinterpreting others and if you continue making false attributions, then those who you mention will have the right to correct you.

Juan said:
Do you mean a 2013 chip released backward in time (2012) thanks to a time machine?

Also if you pretend that a more modern Intel chip would win, then you again ignore how a dual-core Apple humiliated, some few weeks ago, the more modern and strongest quad-core attempt by Intel.

Even Intel fans are accepting the hard facts:

so samsung right now has a better ARM cpu than the cortex A15?

And hard facts ... coming from anandtech's forum ... HAHAHAHAHA!!!!!

AMD is releasing ARM chips ... Why does that mean AMD is scrapping x86 products? Why is it a stupid move to diversify products?

Let me rephrase that, how many times has a company gone under by putting all their eggs in one basket, a basket that has a plethora of competition?

You missed the point once again.

try discussing instead of this ... whatever this fallback overused attempt is.

Tegra 5 isn't just a phone chip. It's supposedly 50 times faster than Tegra 2 so it should be a beast of a chip. Good for tablets, desktops and supercomputers!

Besides the question was "how long will it be before you can run BF4/Crysis3 on an ARM platform". And your response was a poor quality demo of a stripped down BF3 on hardware that isn't supposed to ship until sometime 2H2014.

Now the Tegra 6 (project Denver) you've been mentioning is only 100 times faster than Tegra 2, so that would make it only twice as fast as Tegra 5. Maybe then all the graphics for BF3 could be enabled in 2H2015? A game released in 2011. That's not horrible I guess (4 years after launch), but consoles will be at their peak of optimization with BF5 or some such Frostbite 4 engine.





And that somehow negates the fact that the A7 won in 1 (out of 4) CPU benchmarks in that review? How can the A7 humiliate Silvermont by winning 1 CPU benchmark? Who in their right mind would use the term humiliate with a 25% win ratio?

you have been saying it the last 10+ pages.

AMD heads are not fanboys, AMD is replacing its own Temash tablet by ARM tablets, and its own jaguar servers by ARM servers. Everyone is applauding the move, except ARM-haters.

when you replace something, you scrap what your not using, unless you are actually saying AMD is going to do both, Temash. jaguar, and ARM, wich contradicts what you just said in the first place.

A phone chip is one with a phone-class TDP rating. If you can introduce more performance than competence in that thermal package that is welcomed.

No, Tegra 5 is _not_ aimed at desktops and supercomputers. As Nvidia claims, their Denver project is aimed to desktops and supercomputers. Tegra 5 is not based in Denver.



I think this answer my question quoted at the top.



Some time ago I computed the expected performance for Tegra 6 and I got something as ~800 GFLOPs if I recall correctly.



I will bold the relevant parts:

Dude, even I will admit that it seems Intel needs to admit defeat to ARM. 1.3GHz dual core A7 with Smartphone class TDP is beating 4 core 1.4-2.4GHz Bay Trail with Tablet class TDP. And that's "28nm" vs 22nm.

The IPC of the A7 is on par with Ivy Bridge parts! Clock that sucker to 3GHz and it'll have a no worry replacement for the Macbook Air line and threaten even with x86 emulation.
 


The main problem is, at a minimum, you are using different OS's, software versions, etc, so there will ALWAYS be ambiguity unless you write programs in optimized assembly for both arches and test that way. Closest thing you can do is test a mostly optimal program in an OS that supports both arches (say, Linux or Android), and accept there will be some noise in the data.

At the end of the day, in regards to CPU performance, X86 wins, easily. By how much is up for debate, but even the highest tier ARM looses to the lowest tier X86 (Silvermont). How is ARM going to compete against HW/SR if it can't even beat Atom?

ARM isn't displacing X86 anytime soon. The only reason ARM wants to get into the server market is because of the insane margins available. And lets not forget MIPS and PPC are always around the corner in the low-power market...

I can find the word Apple above. Can you? Hint: it is in bold.



Jaguar servers are replaced by ARM servers and Temash tablets are replaced by ARM tablets. Links and roadmaps were given.

However, your claim was "Why does that mean AMD is scrapping x86 products?", which is not true, because AMD continues selling and developing many x86 products. Did you hear about Kaveri and Steamroller? Warsaw? Berlin?...
 
I doubt ARM will displace X86 when attacking its strong points, just like X86 is not going to displace ARM in their strong points.

Like gamerk says, manufacturers want a low-cost alternative to offer people a desktop experience (want a piece of the Intel DT pie). Intel is expensive, we all know that and ARM looks to be a low-cost part that can handle mundane DT work thanks to the cheap licensing deal behind it. The only thing left is support for that. Putting the "MOAR PERFORMANCE CROWNZORZ!" argument to the side for a moment, more than "this is faster than this", think about a full desktop experience with one or the other.

This is not the best example, but I used a Surface RT (an aunt bought it "by mistake", lol) and it wasn't so terrible. It was Windows alright and it worked differently because of the tablet format, but the Tegra 3 inside proved to be enough for WinRT. I don't really know if WinRT can be called a "full blown DT OS", but at least it sure felt like that for the regular user. It had the thumbed down Office version (I think) and it had the alternative to go into the classic windows interface (start menu + taskbar) and it was good.

So, if AMD decides to displace Temash in favor of an ARM licensed product, why not? I really don't know this for sure, but what about the cost of design and manufacture of an ARM CPU vs an X86 CPU? Is it easier for Foundries to build a RISC or CISC CPU? Is it the same? I mean, the power envelope Temash is targeted at is DIRECTLY in ARMs sweet spot territory. AMD doesn't have a bad relation with ARM, why not exploit that and save costs with the (painful) royalties to Intel? It all makes sense to me, if what I say is true, of course.

And my source is my own behind, so don't bother asking, haha.

Cheers!

Love how you try to change things around. We aren't discussing Apple, YOU are the one discussing Apple as if ios or the Apple swift cpu are unaltered in any way. But lets examine that briefly, and this is the only time I will duscuss Crapple.

The CPU cores are, once again, a custom design by Apple. These aren’t Cortex A57 derivatives (still too early for that), but rather some evolution of Apple’s own Swift architecture
...
and we're likely talking about LPDDR3 memory this time around so there's probably some frequency uplift there as well.

and for the tests, lets optimize the software first.

As of late SunSpider has turned into a bit of a serious optimization target for all browser and hardware vendors, but it can be a good measure of an improving memory subsystem assuming the software doesn't get in the way of the hardware.

so why is Apple A7 able to beat Atom in that test? gee ... I wonder with the state of Android x86 and optimizing the software to go along with the changes Apple incorporated ... ya, and Apple claims Samsung cheats on benchmarks.




Jaguar servers are replaced by ARM servers and Temash tablets are replaced by ARM tablets. Links and roadmaps were given.

Where did I say AMD was scrapping ALL x86?

Temash, jaguar, kabini, ect are x86 products are they not?

If they are scrapped according to your wishes, then AMD is scrapping x86 products are they not?

The TR article stated AMD was going to INTRODUCE ARM products, not replace. Your the one who put that word in there.

http://wccftech.com/amd-jaguar-based-beema-mullins-apus-confirmed-2014-feature-hsa-enhancements/

So is this the scrapped x86 products?
 

i am just trying to jog your memory, i could remember it wrong myself, so...
anywho, iirc, the original claims(made by juanrga) were: (edit:compilation of, not direct quotes)
amd is replacing jaguar with arm cores in microservers.
warsaw is for legacy support.
temash is being replaced by arm soc.
amd will not make 4+ core cpus, no need for them anymore.
kaveri, berlin, warsaw do not have (much of) a future. <- this may have been very, very, very, very strongly implied instead of being explicitly stated, i can't remember clearly.

so... the ones that are left.... i guess... are the discreet gfx cards for x86 platform, which, amd are not abandoning, apparently... :whistle:

....
wait. somehow, the 4 core cpus (apus sans igpus) seem to not have been abandoned by amd. edtit: so did single/dual/tri core cpus. yay. on a less happy note, amd seems to have entirely abandoned L3 cache.<sadface>

LOL...are you seriously suggesting that the tablet OS is a full blown desktop OS???

You might be crazier than I expected...LOL!!!!

That's a good one, Android tablet OS is the "ARM OS" solution....

Have you used a chromebook? Talk to me when you have...Chrome OS is roughly 2-3x more features than Android, and it's not even a rough fill in for a real desktop OS.

The thing that someone wants to ignore is the fact that SR-FX or whatever they decide to call it was never slated to be released before 2015. AMD has since released an APU roadmap and has been taken to mean that is the only products that will ever exist. No products other than those on the APU roadmap are in development. They also have gone as far as saying the existence of high end ARM will cancel the existence of low end x86.

AMD supposedly abandoning high end cpus leaves only middle performance APU for x86 support or Intel for ALL high end computing. ARM is not high end. Maybe 2, 5, 8 years from now, who knows how long that will take. Some people are convinced that is already here today based on personal opinion.

If this truthfully is the case, I may have purchased my last AMD cpu. I am not interested in a downgrade powered cpu to play games at medium to low settings. If ARM is the only choice to make in the future, ill go with Samsung or Qualcomm since AMD is forcing the choice (or rather lack of choice).

AMD needs to play both markets. They can't survive with a middle performance only x86 cpu, (think VIA) and ARM is full of competition already.
