Yeah, no. What kills chips is electromigration, and the mean time to failure of a conductor due to electromigration has an (approximately) exponential dependence on temperature. If you're a frequent gamer and your games bring your chip up to 90-100C, I wouldn't be surprised if it burns out before the year's done.

Also, the processor will throttle down to prevent immanent damage. It won't stop long-term damage from accumulating.

It's a function of both voltage and heat isn't it? My thinking is that at a given voltage, an increase in temperature may produce an exponential increase of electromigration, decrease the voltage will produce less heat and less Electromigration directly (as it's inherently a function of current / current density). With a lower voltage there is less charge that needs to be moved, and thus, less current. Of course if it's too low the system may become unstable and crash, and they've obviously put all the effort they can into making the stock chip as low voltage while remaining stable for nearly everyone.

and lower voltages should produce less heat in the first place, so the whole thing is a combination of voltage and cooling

I did some fiddling around with the only setting I thought might cause an issue, which was the CPU load-line calibration. I was using a fairly aggressive value to compensate for vdroop, but it turns out that setting might have been giving a boost in voltage, perhaps +.05 or so. Changing the setting to be more conservative has resulted in a more reasonable core voltage of 1.280 under full load, for temps of ~70 for all cores under Prime 95.

Thanks for the tip!

Load-line calibration can put dangerously high voltage to your CPU. Definitely never turn it up to max.

I personally feel the practical danger of LLC is overstated with some manufacturers. I've been using it since a Q9550 at, I want to say 4.3GHz on the very board where they first demonstrated that LLC is a violation of the CPU specified voltage delivery and that vdroop is part of how it is intended to work. Going strong (and by that I mean passing whatever stress tests you want to toss at it and never kicking an error in use) five years later.

I think the thing to do is to just realize that LLC is basically very quick bursts of higher voltage. So treat LLC as almost identical to but not exactly the same as just raising voltage and don't go nuts with it, especially on Gigabyte motherboards as their power delivery is extremely aggressive. You can get a total lower power delivery over time which in its own small way does extend the life of the chip compared to axing LLC and just upping voltage.

I doubt it will be necessary or even particularly germane to future CPU generations, though. Yeah, power delivery components on the motherboard will still be significant, but moving so much of what regulates the operating voltage and all that to a more integrated platform is going to make it less meaningful.

Otellini announced he was retiring back in November, oddly timed since he could have gone a couple more years if memory serves.

I no longer work for the company, but I'm still not sure how much of that is public or not so apologies on being vague.

That was the original reason, IBM required a second source for every component. Today they have an x86 license because Intel needs an AMD64 license :) It definitely would have been a monopoly issue a few years ago, but today Intel could make a compelling argument that ARM provides such strong competition that there's no need to have additional competition within the x86 space.

Consoles aren't huge volumes though. The PS3 shipped 70M over 6 years, Ivybridge shipped 100M in one year. Different margins and continuing engineering support profiles too.

Totally agreed on the x86 monopoly/ARM issue though. ARM's in a great position and there have been a few decades of research to abstract away the ISA layer between HLL's and performance. Apple in particular has practical experience swapping out the ISA and complete control of the iOS toolchain. I still think ARM would have huge growing pains if they tried to scale to a billion+ transistors and it isn't a given they could get to today's desktop range without burning up. But a monopoly on x86 isn't worth what it used to be.

Especially since the huge push to mobile means ARM at this point - I was looking in the stats of a website I'm running with a client, and out of the something like 650,000 visits last month, nearly 60% were classified as mobile - iOS and some form of a billion android devices was 99% of that. And this isn't a site that appeals to someone that is technologically savvy - if anything, it's the opposite.

That's nearly triple what it was last year - and Intel isn't selling those chips.

There were monumental shifts to correct course there. The board was surely aware of the justifications stretching back to when Xscale was sold off and I don't think they'd hold it against him.

Without insider information we really can't do much more than speculate safely enough that the console wins will provide them with a much-needed financial buffer; beyond that, ever since the original xBox where nVidia contractually roped Microsoft into buying the then-current video card tech at launch prices for the entire duration of the console, screwing them pretty bad... I dunno, the various party profits on console hardware are a little too malleable to just categorically say that AMD's totes safe now that they're providing the CPUs and GPUs for the two big consoles and the GPU for the little one.

Going to make them money? Thank goodness yes. Going to make them rich? Questionable.

Yudo
May 15, 2003

I remember reading somewhere (so please take with a grain of salt) that AMD is going to gain a revenue stream yes, but not a particularity large one as they are not making that much per console APU. I doubt, in fact, they will have close to the margins Intel has, but then again that market is in a tailspin. The real boon, aside from actually making money, is having a leg up in the gaming market as code will be optimized for their products and perhaps be HSA compliant.

ARM ISA chips have more or less reached "good enough" status in the mobile market. I was astonished with the Exynos in my Note II + Android, it totally blew the doors off the POS dual core atom that now collects dust somewhere in my apartment. Silvermont may help Intel get into the SoC and low end market, but I wonder if Intel can adapt to the sort of razor thin margins that it requires. I don't doubt chipzilla's ability, though I do their acumen. They are awfully late to the game.

Control over the CPU-GPU HSA, maybe. That's AMD's big push and big hope, yet Haswell having the ability to push a GPU memory-space pointer to the CPU shows that Intel is trying to do the same thing. If Intel had AMD, then Intel could do one, non-segmented HSA for x86. Especially one which conveniently only worked with Iris and Radeon hardware, leaving Nvidia at a disadvantage in the compute space it gets so much money from.

Praise be to China's Covid-Zero Policy
Intel - 2012 revenue: $53 billion
AMD - 2012 revenue: $5.4 billion
ARM Holdings - 2012 revenue: $0.9 billion

(Source: Wikipedia, 1 pound = 1.55 dollars)

So yeah, Intel needs to totally buy ARM immediately lest they be obliterated in the next 3 months or something. This would not have any negative influence on the market. In other news, Coca Cola just got approval to buy PepsiCo in order to prevent being pushed out of the market by Virgin Cola.

I'm not an economist, but if revenue is an indicator of scale, then I'd think Intel and AMD still have no excuse to merge. Maybe in a few years.

I think some people fail to realize that ARM doesn't make any of the processors they design; they just license the processors to other companies to make them. One of the reasons why they're so popular is because their licenses are cheap and easy to obtain. In fact, Intel already has a license for an older ARM processor design.

Market share is the usual metric. We know ARM is a giant threat to Intel thanks to its domination of the mobile/tablet markets which are still growing. We'll see if Silvermont/Haswell let Intel make inroads back, but it looks like this is a repeat of the early AMD competition where Intel got caught napping (here, on power consumption) and is throwing bags of money at catching up.

Great, once you go out and find the revenue numbers for the companies that actually design ARM SoC's, the companies that fab them, the companies that integrate devices around them, and the plethora of companies that provide third-party support for compiling, debugging, etc. and total all those up to get a reasonable estimate of the revenue the ARM ecosystem is chugging through you might have a comparison that isn't utterly ignorant of the market. Short list would be Qualcomm, Samsung, TSMC, Apple, Atmel...

iPhones alone have shipped >250M, iPads >100M. That's dwarfed by the number of Androids. Cell phones are a fraction of the raw count of ARM cores shipping. The margins are a different picture and a core-to-core count isn't great, but the basic picture is that ARM currently dominates mobile and mobile's on the way up.

HSA wouldn't really help by itself. Anyone can slap the same labels on a memory range and point compute agents at it. The problem is making the hardware support it quickly and coherently, and the ATI acquisition showed us just how long HW design integration takes.

Carriers are also eliminating their early upgrade discounts left and right. Verizon just made the cycle 24 months (the full term of the contact) rather than 20 months. That alone is going to slow down the upgrade cycle quite a bit. No contract and pay as you go also puts a wrench in the whole "get a new device every 1 1/2 years" mindset.

Yes, there's some damage attrition, but people are starting to keep phones longer and longer. I got a couple of friends right now that are sitting on 3+ year old smartphones because they are working "good enough" and are waiting for the "next big thing."

There is still quite a bit of ways to go though before the market levels out since you have all the developing countries that are seeing massive growth in smartphones, but it will come eventually.
