Hertz are hertz, but don't make the assumption that on intel, adding a processor doubles the throughput. The target market for x86 emulation would be older processors in need of upgrade - not new ones. Nobody who wants to impress their management should be recommending this solution until it's proven viable.

Eh, Barton, you mean 1 Intel 2ghz core, don't you? Assuming an Intel server to be 2
quad-core sockets, that would be almost 1 z10 IFL versus 1 Intel server. Or do I completely misunderstand you?

Simple arithmetic: Emulation normally takes an order of magnitude more cycles. Thus a workload that consumes 10% of a 2Ghz intel processor would consume 1/2 of a z10 IFL. Even with the new low price for z10 IFL, making a business case would be difficult. The Mantissa website seems to focus on education - one class can have their "intel" servers, then when the class is over, the next class can have their "intel" servers - that could make business sense if academia looks for business sense - but VMWare is likely going to be a better business case. If Mantissa is very good at miracles and they get only 2 times the cycle requirement, with servers that are 10% busy, assuming 2ghz processors, one z10 IFL will max out replacing 10 intel servers. I will be eagerly waiting to see some real performance data. (And of course when someone asked to put up open solaris on our z9, i quickly said yes as performance will be "interesting" i am sure).
