    Still waiting for a day without x86 everywhere

      You don't have x86 everywhere. Look at all your mobile devices, the things connected to your TV or your car. Heck even an x86 based computer has more non-x86 processors in it than x86! For example almost all SSD drives have an ARM chip, the GPU is not x86, the network device has some sort of processor, and there are various other processors (eg power control on laptops), system management processors etc. If you just looked at numbers of processors shipped then x86 is almost irrelevant.

        718 bogomips? My Phenom II is at 7061, with a TDP of 125W. i know bogomips are not very precise when used to compare different architectures, buy still I don't see that much difference in efficiency....

          Yeah, I'd like to get one of those dual CPU boards if only I could fit it with a 16x GPU as they are trying for compatibility with off the shelf PCI and PCIe boards as well as X86 emulation. The pics of the boards I saw only had closed ended 8x, 4x and 1x slots.

            The -bogo- in bogomips is short for bogus. It's less useful than glxgears for comparing performance.

              Still, it seems to be just about right considering the ramspeed results are also very low in the 240~300MB/s.

              Unless this is a 1W CPU I'm not impressed.

                No, not still. It's completely bogus.

                  well OC the ram speed results are very low , its not likely Loongson are going to licence the latest wideIO AKA 512 bit wide bus (4x128) with far lower power usage and yet far greater speed throughput (up to 17GBps),or even come up with their own compatible version soon and that's a shame as it looks to potentially become a well used lowest power usage world standard sooner rather than later if that other upstart doesn't rock the boat.

                    On most x86, bogomips = MHz * 2
                    On most ARM, bogomips = MHz

                    Assuming MIPS is like ARM here, how the heck do you take performance out of the clock speed :P

                      Isn't that the processor that spies on you and reports back to the central committee if you look at news outside the great firewall? All kidding aside can you really trust that processor?

                        On balance, it's probably more trustworthy than TxT/vPro.

                          Advantages?

                          Does the MIPS architecture have any advantage over ARM or x86?
                          Does the Loongson have any advantage over a x86 or ARM?

                          If it is not open source, and have no advantages, why would I want a MIPS?

                            If the central committee tells every comrade you have to use it in your system (so they can have a hardware backdoor into your system) you have to use it or you go to the gulag (or whatever the Chinese version is called).

                              Do ARM systems have: "Hardware-assisted x86 emulation" ?
                              and 64bit right now?
                              And the GS464 core do have a high complex superscalar, out-of-order execution architecture with a complex microcode working internals for high speed optimizations.
                              In the definition of the FSF its 100% open-source software hardware because no closed source firmware is needed.
                              Richard Stallman use a Longson2 based system because of this.

                              This means its more trustfully than Intel: "Trusted Execution Technology"
