The only way IPF gets close is if you use the new 1.4Ghz 1.5MB cache chip Intel just released as a response to Opteron. The price of a p690 is so high, don't bother. >But if we started talking about "price/performance" why not look at the ordinary >Xeon or Pentium4? They have performance comparable to Opteron (within ~10%), and >very competive price... > For SMP server systems: http://www.spec.org/cpu2000/results/res2003q3/cpu2000-20030714-02406.html http://www.spec.org/cpu2000/results/res2003q3/cpu2000-20030728-02426.html Not even close. If you compare Opteron versus a uni-processor desktop, it is back to competitive: http://www.spec.org/cpu2000/results/res2003q3/cpu2000-20030728-02428.html http://www.spec.org/cpu2000/results/res2003q3/cpu2000-20030616-02266.html But I would argue that's not a fair comparison until AMD releases their Athlon64 product.
