Tenchusatsu and Scumbria Thank you for the excellent comments. I agree with many of your comments. They provoked some minor retorts (that I have put below) as I read them. Tenchusatsu <Alpha's biggest threat is Merced and McKinley, but of course, it isn't here yet.> I agree entirely. I believe, based upon what I have heard, the Merced will be possibly be a disaster for those expecting good performance or a low cost part. However, the McKinley is rumored to be quite a competitor to the Alpha. Alpha of course may be extended in the next few years before the McKinley is ready. Investors want consistant quarter by quarter improvements, but large system developments take a long, long time. <Actually, I don't think extended addressing is that hard to achieve. It was done for Xeon without too much trouble (I think), and it can't be too hard to come out with a K7-derivative that has extended addressing.> Some hacked up addressing is trivial to add. However poorly done, afterthought extensions cause software bugs and do not achieve the maximum performance levels. There were cases of this in going from 8 bit, and 16 bit processors to the next generation. The transition to 64 may be a little different, because 32 bits are a lot and few current applications benefit from 64 bits. <Actually, the Merced will most probably be the fastest x86 processors out there, mainly because Willamette is being released about six months after Merced. > I guess that I would not so confident to put Merced at the "most confident" level. I would estimate that it will possibly be the fastest. Scumbria: <Merced is going nowhere real fast. The chip is huge and will not be manufacturable in quantity. The performance will probably be a great disappointment as well.> This is the sense that I have from what I have heard.
