Expectations
Nobody will be surprised if i845 plus PC133 won't be able to reach the scores of i850 plus RDRAM. The question however is, how much of a performance decrease we will actually see. Applications that rely on high memory bandwidth will suffer, while applications that require short latencies might not perform much worse than on i850.
I also threw my recent Tualatin-results into the equation to see if Pentium 4 plus i845 and PC133 SDRAM is still faster than Pentium III Tualatin. If the latter should not be the case it is very difficult to see a major sense behind the existence of i845/PC133.
