Tench, <Just to make sure that my Alpha facts are straightened out, does EV68 refer to the 21264? Is this the 0.25 micron process, or the 0.18 micron process?> Message 9190704 Pardon your confusion and maybe my lack of explanation. Here is a short overview. The initial 21264 was fabbed/designed for .35 micron. This process is known as EV6. The shrink to .28 micron (of the 21264) is known as EV67. The 21164 is shrinking also, this part is known as EV57. Formerly Digital used to place an "A" designator at the end to give a visual. So if someone said 21164A , we know that is the EV56 aka the .35 shrink of 21164 (21164 started at .5). The shrink of EV6 to EV68 (.18 micron) is the killer "$400" part. <And what is the EV7? The 21364? On what process?> The EV7 is the 21364 in the .18 micron process. As noted earlier, there isn't always a one to one correspondence with feature size, generation/naming stuff. EV68 and EV7 are both .18 micron, two different CPUs, two different target markets. Again, the EV68 will be much more painful from a Merced perspective due to timing and cost. VERY difficult to market against something that is shipping, considerably cheaper ( 1/5 the cost ), and just as powerful.
