    Ars is claiming[^] that MS is planning to add support for 128bit processors in win8. What hardware is this supposed to run on? Attempting to find anything about forthcoming 128bit x86 CPUs only turned up rehashes of this rumor, clueless wishlisting, and confusion over the width of the processor architecture vs the width of SSE type instructions.

    The latest nation. Procrastination.

        Hm Good luck finding an IA-128 in the near future? :)

          Interesting. I haven't heard of anything post 64 bit. Just a dramatic increase in the number of chip cores.

          If the post was helpful, please vote, eh! Current activities: Book: Devils by Fyodor Dostoyevsky Project: Hospital Automation, final stage Learning: Image analysis, LINQ Now and forever, defiant to the end. What is Multiple Sclerosis[^]?

            Maybe not 128b, but C128 (I mean Commodore 128)? :-) It even had Microsoft's OS (BASIC 7).

              I have heard no such thing, and it doesn't make much sense to me. A 64-bit address space is quite sufficient for my needs. Wider data paths are fine in vector units, I don't expect x86 to go and unify its integer and vector units though. :)

                      Of course. The data path is everything that handles data, i.e. data types, registers, data caches, functional units, data buses. They always just double due to physical limitations, e.g. because they need technological improvements to overcome the ground bouncing risk when twice as many bits may change at the same time. :)

                          yeah, all kinds of bits get smaller, their number increases faster though; and as the transistors are getting smaller, they become more sensitive to their environment. When a number goes from 0xFFF...FFF to 0x000...000 all bits change, there is no cancellation; remember, it has to be right all the time, whatever the data (or data sequence) is, under all the specified conditions of supply voltage, clock frequency, and operating temperature. :)

                            Oh, I thought you were making a joke about all those flipping bits causing the computer to vibrate. On a side note: "The 8086 had eight (more or less general) 16-bit registers" that sounds like 128 bits to me so maybe Win8 will run on those. :cool:

                              I have heard no such thing, and it doesn't make much sense to me. A 64-bit address space is quite sufficient for my needs. Wider data paths are fine in vector units, I don't expect x86 to go and unify its integer and vector units though. :)

                              I've never really seen much point in 64-bit tbh, other than for memory addresses. The 8-bit C64 must have had 16-bit addressing to get 64 KB and the older 16-bit Amigas must have had more than 16-bit addressing to get 8 MB (I think that's what the limit was anyway). All without doubling the RAM required to store the optimum sized integer.

                                Unlikely. GPUs are still mostly 32bit, since the 64bit part is unneeded in gaming. Until someone came up with the idea of using them as general purpose processors they were only 24bit.
