- He would have known about the 7100, although not its exact SPECs.
- So, he's not *too* surprised.
-
- What he may have meant, is that HP won't be able to use offchip
- primary cache much longer. That was difficult at 66 MHz, and is
- really impressive at 100 MHz. Even HP can't do it at 200 MHz, surely.
-
- DEC's architects also have a low opinion of HP's high semantic
- loading. That is, HP has instructions that also do some second thing -
- such as skip-on-condition. The Alpha team avoided that, and have
- handwaving arguments about how this will help in future "aggressive"
- implementations.
