    Cloudflare switching to ARM Server, Intel "free" by Q4.

    It was probably obvious, but until now there were not many widely publicized and detailled analysis were an Arm server was that competitive, even on workloads that were supposed to be Arm friendly.

    Does anyone think we'll see ARM replace x86 in desktops?

    Very interesting, thanks for sharing this. From a CPU architecture point of view, the advantage of a reasonably simple ISA is also that it gives you the ability to try new things more easily and validate them. Either you can put the same amount of new ideas faster or for less money (eg...

    HiSilicon Kirin 950 GeekBench

    I can give a few name of people who "works in hardware in Silicon Valley" who I would not trust to give judgement on anything (not even specifically on SoCs ():))

    Jim Keller joins Samsung

    Very true as well, a very talented engineer can do a massive and long lasting difference, but mostly if he can hire and influence a good team around him, which takes time and money, I am not sure he had any of these at AMD, there is a better chance he gets them at Samsung though.

    [Q] ARM vs x86 in consumer space in 10 years

    Not the first time we disagree on almost everything :D Of course it's not easy, but the incentive and the business case for it is very different from what it was 10 years ago. Maybe there is more performance left on the table on the CPU design on the high performance side, but the current...

    [Q] ARM vs x86 in consumer space in 10 years

    The incentive was not as strong, for a long time it was not necessary as you would get a decent performance boost from the CPU itself, then from going to multiple cores. These 2 trends have reached their limits, so there has to be new solutions, even if it is painful. You can also stay still and...

    [Q] ARM vs x86 in consumer space in 10 years

    You are using present tense, this is not the topic! Of course 5 years to have a big shift like this is short, but things are clearly moving towards more dedicated logic, mostly because the general purpose CPU rate of improvement has been really low compared to what it used to be. The point is...

    Jim Keller joins Samsung

    :thumbsup: If you want a public example of what a good base and design principles from the start can give you, you can look at open-source SW projects as well. The most successful projects will always involve 100s or 1000s of people in the end, but they have been created and put into the right...

    [Q] ARM vs x86 in consumer space in 10 years

    Looking at ARM's results: http://www.design-reuse.com/news/38504/arm-q3-2015-financial-results.html it does not seem that obvious: Cortex-A only accounts for 17% of the unit shipment, obviously it has a much higher ASP, but it is still a balanced product portfolio, there are many places that are...

    Apple A9X the new mobile SoC king

    Of course if you are literraly starting your design "from scratch", but noone does that anymore (because it would take years and mountains of cash for an very uncertain result), you take an existing design, tweak it and sometime switch it to a different ISA. This is what Nvidia did with Denver...

    Apple A9X the new mobile SoC king

    No, that's called marketing: - QC choose not to say ARM because they are ARM customers as well as competitors - Apple, not sure what their official line is, but basically it is irrelevant for their marketing target - Applied Micro or Broadcom very happily say that their custom core is an ARM...

    Apple A9X the new mobile SoC king

    Do you really think ARM only gives there architecture licensees the ARM architecture reference manual and nothing else? Put it the other way, do you think ARM would let anyone put on the market an "ARM" cpu that has not even been through a validation that proves it can run ARM code properly...

    Apple A9X the new mobile SoC king

    I wonder if you actually believe what you are saying or are trolling? It is impossible for anyone today to license the x86 ISA and design a new CPU with it, not only for legal reasons, but also technical reasons. Basically it is too complex to do it from scratch without infringing Intel...

    The Intel Atom Thread

    I am struggling to understand how a different of a few $ on the SoC price can lead to a 20$ difference on the retail price, especially from no-name brands with razor-thin margins. Basically there can be 4 explanations: 1. Intel has a much better integration in the SoC, so less components all...

    [Hexus] ARM compares A72 vs Intel Broadwell-Y

    ARM results can hold the comparison with Intel's legendary margins, and they do so by selling "for free". This + the fact people don't care about the CPU in their hands anymore should tell you a lot about how much Intel is threatened. CPU design is not something you can charge 100s of $ anymore...

    Qualcomm moves Cortex A72 to the mid-range

    Any form of power management would work much better if you knew what the workload will be in the future :D The only difference is that bL requires a lot of SW to work, whereas more traditional techniques are mostly HW based. So its reaction time is longer, which means that some use cases are...

    HP stepping away from Itanium

    You know perfectly that you will never get figures for this kind of information, because it's secret and because it's way too complex to give a single figure anyway. And the cost for Intel or AMD to incrementally develop a "new" core can't be compared with a new one from scratch, regardless of...

    Samsung Exynos Thread (big.LITTLE Octa-core)

    Which may be why they are entering the server market... keep the CPU design team busy, and keep a smaller team doing the architectural and modelling research to know if/when there is room for their own implementation against ARM's cores.

    Samsung Exynos Thread (big.LITTLE Octa-core)

    QC competitive advantage is not the custom CPU, it's the ability to create the best possible SoC, the failure to understand that is exactly why people keep thinking that Intel will succeed because "it has better CPUs". When ARM somewhat failed to deliver with the Cortex-A15, QC had Krait...

    Samsung Exynos Thread (big.LITTLE Octa-core)

    5 years? It has been ~3 years for the last 3 generations (from wikipedia): 2007 Cortex-A9 2009 Cortex-A5 2010 Cortex-A15 2011 Cortex-A7 2013 Cortex-A12 2014 Cortex-A17 and that's not counting some fairly heavy changes between some revisions such as what happened with Cortex-A9 and...

    [AT] NVIDIA Denver performance

    Denver does have a native ARM decoder and no x86 one, so even if in theory you could update the translation layer from ARM to x86, you would not get a usable x86 directly from it, it would be far too slow to translate each instruction each time.

    [SeekingAlpha] Cherry Trail not ramping until March 2015

    If you were to remove the A15, you would also remove a big chunk of the interconnect, and you probably would go for lower cost and area pieces of IP around the core: the memory interfaces would be smaller, no or rather simple ISP, no or more limited modem, ...

    [DigiTimes] TSMC 10 nm trial production in 2015, mass production in 2016

    That's called investment, and this has only happened in the last 5-7 years (at least on this scale), which gets us back to the extraordinary boom of small devices called "smartphones". Samsung and TSMC may be half the revenue of Intel, but exactly as Intel has invested to create smaller chips...

    [WSJ] Samsung, Nvidia Shy Away from Server Chip Battle

    The way I read it, it is a snapshot in 2011, not "when 130nm was leading edge". What this graph says is that in 2011, there were more companies at 130nm (when it was very far from leading edge) than at 22/20. 3 years later I don't think this list has changed much, meaning that the trailing...

    [WSJ] Samsung, Nvidia Shy Away from Server Chip Battle

    Although the trend is clear, it does not prove what you imply. It only means that it makes sense for only a limited number of player to be on the latest node, not that none will ever reach this node later when it makes sense for them. It would be interesting to find the same graph every few...

    ambidextrous computing; AMD project skyla..skybridge!

    This is based one the assumption that there is such thing as a "good" SoC and a "bad" SoC, and that each player is going to aim for the same target. Where there is not added value to design, you can simply license a well know piece of IP, so you end up sharing the cost for this, be it the CPU...

    Intel Quark architecture, "1/10th" the power use of Atom

    Intel Quark architecture, "1/10th" the power use of Atom

    Again, the embedded market is VERY different, it's not about cores and process, it's about IOs and integration, tools and ease of use (including support).... Cost is also obviously a factor, but it is in any business, so it does not really make any difference. You can't really just churn out...

    Intel Quark architecture, "1/10th" the power use of Atom

    In the embedded world, ARM offer far better tools than Intel, simply because they are actually used in far more devices and by far more developers. Add to that the fact that the ARM ISA is much simpler than x86, I don't really see any advantage for Intel in this field. For exactly the same...

    Maybe the majority of people are actually happier with what Android let them achieve on this kind of tablet. Why would you want to run your legacy Windows apps on a 8" tablet? it would be mostly unusable anyway. Bay Trail may be very good, but for a tablet usage, it will need Android to be...

    Intel Q213 Results

    As said before, this should be all the more worrying for Intel. They are fighting with companies that don't make a profit selling CPUs, and they are still more profitable than them. This means that the money is now going to different people, for a long time it was going to WinTel, now it goes...

    AnTuTu and Intel

    ARM and AMD do develop their own compilers :rolleyes: The trick (well, one of them) from AnTuTu and/or Intel is that they use a compiler that no one else can or want to use on Android, whereas the other benchmarks use GCC, which is the officially supported compiler for android for ARM and x86...

    Bay Trail benchmark appears online, crushes fastest Snapdragon ARM SoC

    It could happen, but one has to wonder why would the first leak would be on AnTuTu if this was the case. Maybe it's a lot of noise for nothing as well, as anyone can easily counterfeit AnTuTu scores anyway.

    Bay Trail benchmark appears online, crushes fastest Snapdragon ARM SoC

    Every benchmark has one (or even several) bias, you can't really find the perfect benchmark, that in itself is not a problem specific to AnTuTu. That is clearly not acceptable for a benchmark, it needs to give consistent results across runs. If you want to test the burst performance, you can...

    TSMC and ARM Tape-Out First ARM Cortex-A57 Processor on 16 nm FinFET Technology

    The ARM inherent efficiency myth
