From: Wolfgang Kern on 10 Mar 2007 08:26 Hello Guga, Sorry for the delay, > nice to see you again :) Thanks, it was a while... > Those lists are a bit confusing.. I think i�ll do as you did.... > The best list i found so far was here http://www.logix.cz/michal/doc/i386/chp17-00.htm | The list robert provided, also refers to the general purpose mnemonics.. like: | CMP/TEST latency: 1, Throughput = 0.5 | So, i presume that the way they behave is the same as for SSE instructions right ? | I mean, they works more or less like the formula i posted before, right ? Yes, I think so. | But.. if that is true...then why on this documents says that JCC don�t have latency ? JCC... If already fetched, predicted, and condition known in time, then Jcc got latency zero if the branch is not taken (just skipped). If branch is taken, then it depends on more (iteration count,BTL,..) | It is said on Table C10 that for a processor 0F2, the Jcc is not applicable, but it have a Throughput of 0.5...But.. how is that possible ? Not applicable means the value may range from 0...many penalties. | if a instructino don�t use have the latency to compute the clock cycles used to it be issued.. how it works ? I mean, it _could_ works only from the Throughput, but.. if the latency is 0, shouldn�t the Throughput be also 0 ? I thought the Throughput and latency were related to each other. as above, 'not applicable' doesn't mean zero in all case. __ wolfgang to the other question: You can try AOD's cybersciptorium: http://www.cyberscriptorium.com/bookmarks.html search for CPUID

Hi Wolfgang, Tks for the infos. Jim.. the valid list is the last one.. I started it with "Finally : ) :)"... Do you want me to delete the older post, to we get only one list ? The information i collected from many different places... basically searching product by product from computer stores. Some links are: http://www.hothardware.com/viewarticle.aspx?articleid=897 http://www.pcsforeveryone.com/index.php?cPath=1749&page=1 http://www.keenzo.com/showproduct.asp?ID=652769 http://keenzo.com/search.asp (Searched for the string "cpuid" to get a list of all processors links that contains the cpuid value) http://www.google.com/custom?q=Intel+Core+microarchitecture+cpuid&hl=en&oe=ISO-8859-1&client=pub-2666250944335766&cof=FORID:1%3BGL:1%3BS:http://www.msfn.org%3BL:http://www.msfn.org/images/msfn_button.gif%3BLH:33%3BLW:90%3BLBGC:586B86%3BBGC:%23b5becd%3BLC:%233b89cb%3BVLC:%23663399%3BGALT:%233B89CB%3BGFNT:%233b89cb%3BGIMP:%233b89cb%3BDIV:%23336699%3B&domains=Forums%3BUnattended&start=0&sa=N Best Regards Guga

On those manuals have some info on how to retrieve the CPUID information..Also, a easier to read place is here: http://www.answers.com/cpuid Following onme of the external links have some working example os a app made to retrieve this informations. or here: http://isis.faces.ula.ve/COMPUTACION/Software/ChkCpu.htm or at http://www.cpuid.com they have an excelent program that can retrieve everything..

E6) What is the difference between: "Xeon Dual-Core 3040" and a "Pentium D 915"? What is the difference between: "Pentium 1" and a "Pentium D 915" (if not consider GHz of speed)? I like 32 bits cpu, with 32 bits registers but the "Pentium D 915" it seems from above, is a 64bits cpu; does it mean that cpu can read 64 bits instructions (with 64 bits registers too)? Or does it mean it has two cpu of 32 bits that can read only 32 bits instructions? Or does it have 2 modes: one of 2 32 bits cpu, and one of 1 64 bits cpu? if eax=0, cpuid return in eax 6; what does it mean this return value? How do you know how much is fast in GHz a cpu?
