Dual Core Vs 64 bit

[darklord]

Actually it was Intel again, Intel Xeon series of processors was(is) the first true 64 bit processor.
AMD's 64 bit processor is a 32 bit instruction set, STUCK on an existing 32 bit processor, thus making it 64 bit. Its not a native 64bit processor.
Yes, AMD did come up with the first dual core 64 bit processor AFAIK

And I do not think we are differing on the facts dealing with the CPU platform, Laptop, Desktop or Server.

AMD's 64 bit processor is a 32 bit instruction set, STUCK on an existing 32 bit processor, thus making it 64 bit-----> Huh ???? what kind of logic is that ? Do you mean to say its actually a 32bit CPU ? Dude wake up !

Its not a native 64bit processor.-----> And why is that so & if its not 64Bit then what is it ? and what exactly is meant by 'Native' 64 bit ? please explain.

Actually it was Intel again, Intel Xeon series of processors was(is) the first true 64 bit processor.-----> Nope i dont think so.It was the Itanium that was a 64bit processor ,it could emulate 32bit apps but the performance was pathetic.

The difference with AMD A64 is that it can run both 32bit as well as 64bit apps.when a 64bit app is used,the CPU works in true 64bit mode.

Damn it! All chips apart from the one I have are 64-bit. I am the only one that ended up with 32-bit dual-core!

Please refer this - *en.wikipedia.org/wiki/Em64t and this - *en.wikipedia.org/wiki/IA-64

Totally agree, my mistake, it was Itanium

Hey friends find something .... Still low on time so will post later.....
@Darklord thanks for pointing it out that C2D has a shared cache makes sense now since two cores can shares cache and work smartly... they can utilize the whole cache as a single core does at one hence virtually 4 MB cache means 4 MB for each... core else dedicated means only 2 MB for each... with Locality of refrence and LRU and read ahead ...... hmmmmmmm means greater performance...

the link for the instruction set is Ok Actually 3 White papers including architecture is *www.intel.com/technology/architecture/coremicro/
so if anyone has time to kill please download it and read and post to remove any confusions about architecture........

@ Darklord Now true 64 bit procy ...needing to emulate 32 bit and performance sucks does makes sense ....... i check that out too.... AFAIK there shall be no problem for a procy 64 bit to handle 32 or 16 or 8 bit instruction set.........

C ya later ....
Peace

I don't know why is so difficult for u guys to understand.Ok here what the topic was The 64Bit single core or the 32/64 bit Dual Core?

THE ANSWER IS SIMPLE:

WHICHEVER COMES LATER (DUAL CORE) IS BETTER.IT DOESN'T MATTER IF IT IS INTEL OR AMD THE DUAL CORE RULES!!!

I hope it is clear to everyone.
End of Discussion.

Oops i thought everybody here was intrested in knowing why.......
Anyway.....

The answer was given and agreed upon by many here long ago..... The discussion going on is about something else,although related but is OT for sure

Huh ??? U sane ??? AMD introduced the first 64 bit CPU's for desktop processing ... duddeee ...

*www.amd.com/us-en/Processors/ProductInformation/0,,30_118_9485_9487^9493,00.html

Infact , AMD cpu's have much better performance under 64 bit environment compared to the Intel counterparts ...

Well that i know & there is no harm in getting off topic but since its proven that Dual Core is better than single core then why the heck is the question asked again & again?

Why are you asking me ? i didnt even ask the question
My posts are all targetted at correcting certain wrong facts posted earlier and to provide true info,thats all
As to the question being asked again and again, well you should ask the ones who are asking it

Because u was the one who was questioning me!!!The topic was which is better hence majority of votes were Dualcore & which is true.I even don't have any problem with u infact if u are correcting something that a good thing.I mean everyone should have the correct info about their stuff.

 

[darklord]

Dude ! Why would i question you ? Also i have never said that Dual Core is not good.There were some posts which said there are 32 bit Dual Core CPUs,all i did was correct the misconception that there never was a Desktop Dual core chip which was ONLY 32bit
Go through the thread again if you want Also i havent targetted you personally.You asked a question,i answered it,its that simple.

 

[keith_j_snyder2]

So did i,just like u!!!

Wikipedia is not written by pro. buddy!! its all edited by common people.. but you need to know.. ithink you got to search for the Digit mag. in which the first ever article on 64 bit computing came... It was AMD who launched the first ever 64 bit and the Demop 64 bit technology in the market, and INTEL COPIED That thing from AMD...

Xeon wasnt the first 64 bit proccy...

Thats right. The Xeons launched recently are 64 Bit ones. The ones on 65nm and Netburst architecture and the Core architecture based ones.

To put it bluntly,Intel literally reverse engineered AMD64 tech and rechristened it as EM64T , nothing wrong but just informing

 

[shantanu]

@darklord.. that good... , but kumarmohit was wrong...

Sab confuse ho gaye hai yahan:

Please read the last line where I said that AFAIK we are not talking about platform specific processor (even though the thread is about desktop proccy )

~ AFAIK first 64 bit processor was Intel Itanium which was a pure 64bit processor and was a flop.
~ AMD launched a newer technique, which was - Take a 32 bit processor - Stick 64 bit intstuction set on it - you get a 32 + 32 =64bit processor, it was a hit coz it could natively run 32 bit code and 64 bit code as and when available.
~ Intel copied this and named it EM64T or whatever they call it now (Actually they had done this earlier when migrating from 16 to 32 bit processors so ...)
~ AMD launched the first - dual core 64 bit processor - Not the first 64 bit processor.

Again for difference in Itanium and AM64 please visit: *www.planetamd64.com/lofiversion/index.php/t5410.html

I guess this makes it clearer

 

[saurav29]

lol We should have a poll about how Many people are using 64 Bit applications and some one please explain me or not what is the use of 64 bit processing CPU in presence of 32 bit binaries and (Mind you these 64 bit binaries if some can be ported to 32 bits of course with some overheads) Intel sites says that it is future complaint as with more and more 64 bit binaries it will use the resources effectively... BUT i have serious reservations for putting my money in future proofing when they (Read Hardwares Manufacturers) change the specs so rapidly that by the end of the year there are newer plaforms to work with and affordable too..... Most of the people i knew upgrade computer atleast once in an year...... so what the HECK we are fighting about...........
PLZ GUYS post some constructive thoughts rather than who is right and who is wrong and who is dumb and who is smart.......

PS GUYS Get over yourself NO body copies architecture from anybody....... for amd and intel what the bloggers may write use your head... AMD executes 10 instructions per cycle and Intel 8 thats why the true speed of AMD is always less than that of intel what they say is that a 2000+ AMD procy running on ~1800 will excute the same no of instructions executed by Intel running at 2000.... Infact Intel is considered Defacto of Computing standard and AMD rates its cpu on basis of that only....

Please do not think i support or oppose intel i use AMD 3000+ and what i am saying is only on basis of what i know.... No prefrences of AMD or INtel...

lol , i was thinking that 64 bit is better than dual core

 

[thunderbird.117]

I read did not understand the meaning of this thread. 64bit and dual core is different?. How can i compare?.
