Happy to hear that this tiny chip could give 486, Pentium kind of performance, that would be great!! Will this be somewhere close to the SoC launched by AMD recently: G-series SoC? Probably having lower performance and features than that?
The part that scares me is "...suggesting it is more of a rushed trial balloon than a nailed-down product and strategy."
I would dare not think about using it if there are no clear strategy and a clear road-map. Any tentative timeline announced for its release?
I will be very much interested to hear this. Some of the Cortex M devices are reaching this level of performance. If Intel comes down this far, and QFN/QFP packages are available, I could see this being a possible device that a hobbiest could use. I will be very interested to see more about this device.
I am particularly curious to see what packaging options this device will come in. I am wondering if this product is aimed at the Cortex M market, or the lower end of the Cortex A series? If it is aimed at the M, say M4F with a higher clock speed, it would be interesting to see this type of device in a QFN and QFP. If it is competing with the A series, I expect that this will only be available as a BGA.
I don't know anything, except that AMD64 introduced a lot more than just a bigger address space. IA32 is really not a good/modern ISA, and it would be quite strange to see Intel falling back 10+ years. one real register, stack-based x87, no vectorization, etc. at the time, 64b extensions were justified as not adding a lot of chip complexity - of course that's relative to OoO/superscalar stuff.
