- The Alpha is a _really_ nice workstation - it sort of spoils you for
- sluggish processors like the 486/66 :-). But I'm not sure that the
- logic here is sound -- if you're upgrading your OS and your hardware,
- but trying to keep your application software, would you rather get a P5
- which might run 1/3 to 1/2 the speed of the Alpha but which didn't have
- to run all your x86 software in emulation mode, or would you rather
- get the Alpha and run everything interpretively?
-
- If you have one or two critical apps that require lots of performance
- that you can get in native mode for the Alpha, and you have a lot of
- not-so-critical apps that you can run in emulation mode, the choice is
- less obvious. Certainly Alpha is very tempting for its sheer speed (as
- I said, it's very impressive to work with). But if all of your apps
- are being run in emulation mode, it probably won't be any faster than,
- and will likely be slower than, the P5. Why pay the cost premium for
- the Porsche when the Chevy runs your software at the same speed?
-
- The attraction of NT on the Alpha would be that it gives developers
- the _opportunity_ (though not necessarily the _need_) to compile their
- code for NT on Alpha and sell users a really fast app; if you're
- considering upgrading your apps (for example, you're really hurting
- for speed), then this makes Alpha and NT very attractive. But if
- you're not ... I don't follow your logic here.
