'Snapdragon 1000' Chip May Be Designed For PCs From the Ground Up (engadget.com) 104

Qualcomm's Snapdragon 850 processor may be intended for PCs, but it's still a half step -- it's really a higher-clocked version of the same processor you'd find in your phone. The company may be more adventurous the next time, though. From a report: WinFuture says it has obtained details surrounding SDM1000 (possibly Snapdragon 1000), a previously hinted-at CPU that would be designed from the start for PCs. It would have a relatively huge design compared to most ARM designs (20mm x 15mm) and would consume a laptop-like 12W of power across the entire system-on-a-chip. It would compete directly with Intel's low-power Core processors where the existing 835 isn't really in the ballpark. A reference design found in import databases might give a clue as to what you could expect: it'd have up to 16GB of RAM and two 128GB storage modules.

      Do you mean 64-bit x86 applications or 64-bit ARM applications? This chip is using 64-bit ARM cores, so will run 64-bit software natively. Whether it runs 64-bit x86 software is a question of the functionality of the emulator, not of the hardware. I don't believe that Microsoft's x86 emulator supports 64-bit programs yet, but it was announced to be on the roadmap a few months back.
      • If Microsoft can compile Windows/Office/Edge/Visual Studio/.Net/etc. in native ARM code and run other software via. an emulator then they've got a good proposition for for a lot of people.

        I assume native versions of major apps like Firefox/Chrome/etc. will be ready for launch day. What else does the average user need?

        PC used to mean Personal Computer. That could be any architecture. Somewhere along the line (possibly before those Mac vs PC commercials) PC came to be assumed Windows on Intel (most Luddites don't even know about AMD, much less VIA and other x86 competitors) A PC could be SuperH architecture running FreeBSD. IIRC, there was a company that tried to trademark "PC LAPTOPS", but PC had become so associated with Windows and Intel that the examiners sited the use of PC as an adjective.

          • My wife and most of her friends call iPads "computers".

            Technically they're correct. iPads do a lot of computations, so they're computers.

            But if we're going to be pedantic, then the correct term is "digital computer", so as to distinguish it from "analog computers", and these two, taken together under the single umbrella term "electronic computers", from the original, human computers, since "computing" used to be a profession. In fact, the word "computer" in particular refers to a male professional, a female one being called a computress.

          And unless the Snapdragon 1000 is miraculously clocked at something impossible with present technology, like 8,000MHz, any i7 -- even a dualcore mobile one that's basically *shit* -- will completely roast it at running x86 & AMD64 apps.

          x86/AMD64 have literally evolved hand-in-hand with Windows for 30 years. Today, "pure" RISC might reduce costs & allow high performance for apps built to run the "RISC" way, but when it comes to maximum balls-to-the-wall brute-force winning performance, AMD64 wins, hands down. A modern best-of-breed AMD64 chip is basically a RISC chip, augmented by thousands of additional specialized instructions to accelerate things that Windows (and Linux) PCs *do*. AMD64 processors are basically now like self-optimizing JIT compilers for x86 assembly, with plenty of additional tricks to accelerate and optimize nearly every chokepoint known to exist in Windows (and Linux).

          My phone has a Snapdragon 850 with 4x1.5GHz + 4x2GHz cores, 3 gigs of RAM, and 128 gigs of eMMC SSD. Frankly, Acrobat Viewer runs faster on an ancient, creaky 15 year old Compaq Armada m700 with 500mhz Pentium III, 512mb, and a noname PATA SSD from China (that probabiy has microSD cards hand-soldered to an ASIC inside) than it does on my phone.

          When comparing ARM to AMD64, specs alone don't come anywhere CLOSE to telling the real story.

          What's that? It's for people who "just" use it for running browser-based apps? Ok, go to walmart.com, amazon.com, or sears.com with the fastest ARM-based phone or tablet you can find, and compare the experience to even a *shit* AMD64-based PC or laptop. The PC or laptop will win, hands-down, because Javascript performance in particular suffers *horribly* on ARM compared to AMD64. Sites like the aforementioned that build pages from the inside-out using Javascript, DOM, and AJAX work just fine on a real computer, but turn into a minefield of delayed clicks and pages that keep reflowing and recomposing more slowly than you can see, but faster than your finger can react once you go to touch something.

          ARM is why we can't have nice things like Aero Glass anymore (MS took it away & forced Metro on us because otherwise, Windows would have been unusably slow on crap ARM-based tablets). Dammit, it's almost 2020... we should have UIs with butter-smooth realtime-raytraced refraction & translucency effects by now, not something that looks like a fsck'ing mess of Post-It notes.

            Bear in mind a phone CPU is optimised for a minuscule battery inside a fanless enclosure. This 1000 series will be tuned for 2-in-1 laptop performance.
            That said, Google's venture into ARM64 Chromebooks should result in performance gains on V8 as they fine tune the OS.

            PDF viewing and web sites like Amazon work just fine on ARM Chromebooks. Maybe Chrome's JS engine is better than whatever you are using, because it's used for both.

            Your comment about MS removing Aero Glass because of ARM is just bizarre. Have you not noticed that phones tend to have far more graphical flourishes and effects than desktops? And at comparable or higher resolutions too, with 1920x1080 being decidedly mid-range for a phone now.

            Mobile GPUs are pretty powerful and, like desktop ones, offload a lot

            • No, the decision to eliminate Aero Glass was deliberate & based on a perceived need to make Windows run acceptably on tablet & netbook-class hardware, which is MASSIVELY inferior in performance to any hardware most of us would consider remotely acceptable.

              GPU capabilities have improved, but back when the first netbooks & tablets appeared, there were a lot of scenarios where Windows was being run with 24-bit color, but the GPU could only do hardware-accelerated transformations in 15/16-bit color.

        • Emulation = slow 'n buggy.
          • Not necessarily. True, a high quality implementation is going to be large because quality emulators are compilers, but there might be great demand for x86-on-ARM emulators and therefore a correspondingly large funding for those efforts.

    This wouldn't be engineered for PCs, this would be engineered for budget laptops AKA tablets with keyboards. What's the difference? PCs have a common bus (or at least can outsource the job), the modern one being PCIe. Honestly, this is still just another beefed up smartphone chip.

      So you'd plug what in? A modem card?

      Not a flash card because they're all flash now anyway. Graphics are built right into the SOC with a much faster internal bus, so not a graphics card. Peripheral are all USB these days.

      What exactly would you plug into the slot, and why do laptops not have that slot and yet still sell?

        My desktop has PCIe slots populated with dual NV Quadro GPUs, an accelerated 2*40Gbps Ethernet NIC, and a SAS controller. Some people really can't get enough PCIe lanes.

    • And isn't that a common bus? Not as fast as PCIe so you're not gonna be running a GTA 1080 off it but it's still a bus isn't it?
      • USB is an example of a port, the distinction being that it's an external device. Lots of stuff used to plug into serial ports but that didn't mean you considered any device to have a serial port to be a PC. Sure, it's semantic distinction and arguably subjective but that's what this all about to start with. However, if you're ignoring all that, I have a PC to sell you, it's called "Arduino". ;)

      You do realize that the desktop market is much smaller than the laptop market right? And unless your laptop has a TB3 port and you're using it with a docking station, RAID enclosure or something similar that actually speaks PCIe then nobody cares what goes on internally. Users just care that the external ports work, primarily the screen (HDMI/DP) and all things USB. Heck many business desktops probably don't have a single expansion card either and the AIOs are usually laptops in drag. If I'm generous I'd s
