The Intel BTB is _far_ better than >that on any of the other processors you mentioned. I wouldn't bet on that. The K6-2 (? -- One, or all, of the K6 series, anyway) had better branch prediction than any of those processors, including the P4. I'm sure Opteron's is not worse than P4's. I can give tons of references for the K6 data if you'd like.
