But seriously, the explosion of options are just a return to the past. Risc, Mips, Cisc, Vax, Power, Sparc, Itanium. There has historically been plenty of architecture options.
      You forgot the finest of them all, the DEC Alpha! Still have one in my basement, running Gentoo.

        well, this is good for predicting some future driver, but we already have driver, so you could just compare existing drivers instead of comparing some theories. and existing reverse engineered freedreno is best arm opengl driver atm

        but freedreno does have longterm dev on payroll. on redhat's payroll, but still

        why do you look at nouveau instead of looking at freedreno?

          By "generic installer", do you guys refer to the pre-boot system, e.g. UEFI, BIOS, coreboot?

            So you're piling closed blobs upon closed blobs ? What could possibly go wrong...
            To be fair, I said MORE open source friendly, not actually open source friendly. We just started from a pretty low point with ARM chip manufacturers. Pretty much anything else is better. Plus, it isn't hidden if people know about it and it is documented in AMD whitepapers.

              Its hard to believe, because every time i used them, response time for work was PITA, maybe Android would be run fast enough on them, not is not good for basic desktop work.

              Do you have any calculations, how much time users just burn on waiting on some compute? Because usually make sense for employer to spend money at stronger HW, because people with it can do more work with same effort.. Otherwise we would have everywhere just cheap Pentiums or old AMD CPUs.

                no, that's not linux

                  To clarify, with "we here" I was meaning my family, not an office with employees. My wife and kids do their Thunderbird, Vivaldi and Libreoffice tasks perfectly fine with their Raspberry Pi3 running Xubuntu 16 LTS, since these applications on the slim XFCE desktop don't need number-crunching power but run smooth enough on the four 1,2 GHz ARM8 cores. Albeit still in 32 bit only so far – as soon as there's a 64 bit Raspbian/Ubuntu, we will gain more speed from 64 bit.

                  Also for my evening leisure tasks a Pi3 is fine, but indeed for IT day work I use a faster machine than a Pi, for the reasons you mentioned.

                  So I'm very interested in these new powerful and current-saving ARM machines mentioned in Michael's article. I would any day replace my bloated x86 desktop machine with an ARM powered Linux one.

                    Just look at nouveau - one of the hugest reverse engineering effort - that still sort-of works if you happen to have a chipset that matches one of those that the devs can test on, etc. but there are still weird bugs creeping on.
                    Vs. amdgpu which basically works, and if it doesn't (like some of the recent chips during the early time after their release) there actual devs paid to fix the problems ASAP.

                    I don't want to denigrate the efforts of the nouveau team. They are doing wonders given the circumstances.
                    But they are severly limited in what they can do due to lack of resources.
                    I think the more fitting comparison is the Freedreno driver, as it also concerns ARM platforms. Started without help from Qualcomm, reverse engineered, but soon surpassed the vendor driver in performance and quality. Then Qualcomm (or rather Qualcomm's customers, I suppose) started noticing and now Qualcomm officially works on that driver.

                    Now that you mention NVidia, there is actually an example for that company too, which is the forcedeth driver for the integrated Ethernet in NForce chipsets. NVidia originally released only their own proprietary ethernet driver.

                      BGR is reporting that the Windows 10 gear running Snapdragon 835 is just a placeholder until the Snapdragon 845 is released next year. They are suggesting people hold off and not buy the units with the 835 and wait until the 845 is available.

                      
The new processor is 25% more powerful than its predecessor, and graphics performance is up by 30%. These are relevant parameters, especially when talking about machines that should run Windows 10 apps. And there’s support for AR and VR features built into Qualcomm’s Snapdragon 845 platform, and we all know Microsoft is betting big on such experiences for the future of Windows 10.

                      Moreover, the chip comes with a new built-in Snapdragon X20 LTE modem that supports theoretical LTE speeds of up to 1.2Gbps. Wi-Fi speeds now support the 802.11ad standard, and there’s Bluetooth 5.0 support inside the 845.


                      The 845 is the basis for all of the next gen phones (ie: Galaxy/Note 9) and Samsung has been showing off a dock that allows one to run Win32 apps on their phone when it is docked.

                      Speaking of docked, Win32 app support on the 835/845 is being done via an app container using Hyper-V, similar to how Docker on Windows works.
