As per Intel's P4 sSpec info etal, 1.6A, 1.8A, 2A, and 2.2 are 512k L2 Cache and 0.13 micron. All others are 256k Cache and 0.18 micron.
If I get a P4 instead of an AMD XP, it'll have to be a Northwood. Have to decide on a motherboard too. And a case or just replace the ps. I could get a retail AMD XP 1900 with Soyo SY-K7V Dragon+ for $329 at Fry's or a retail 1.6A Intel with Soyo SY-P4S Dragon Ultra for $312. Any recommendations on these or others?
