Intel 5xx J CPUs and EIST (speedstep)

[jarthel]

A member of an Australian computer forums mentioned that the Intel channel roadmap does not mentioned EIST in the J CPUs.

Also this publicly available page ([L=[URL]http://www.intel.com/products/...essor_number/info.htm)]http://www.intel.com/products/processor_number/info.htm)[/L[/URL]] does not discuss EIST with J CPUs.

Anand's Intel roadmap talks about EDB and EIST for the J CPUs. http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2256

Which is true?

I need to buy a CPU soon and if EIST will be appearing in Q1 05, I'll just get what's available now.

Thanks
