3 competition: struggling to keep up with superdome page 3 non-disclosure until september 18, has experienced a data corruption problem - has experienced delays - similar power to pa a generation behind in power, 750 mhz pa-8700 is 43% faster* - depends on slower external cache - mediocre performance, older technology - requires aix 5L, a major new os migration - need to recompile for full 64 bit advantages - requires costly application retesting as thisis a chip and os migration - no compatibility with Itanium, major transition issue sun ultrasparc III ibm power3/power pc ibm power4(future) compa q alpha *than sun 900 mhz us III based on spec_fp_base2000
