Dual core & Core 2 duo!!

[geethq]

Oyaa thiyenneee!!!

 

[Novindu]

Higher IPC
Low latency cache
High FSB
Improved branch predictor
Improved SSE engine with more instructions
Macro and Mrco-op fusion
Improved prefetching
.....

hmm dats not sat simple eeh???lol..thz man
so what if some 1 ask wus da differense...what can we say????i mean to a beginer

Core 2 is faster than Pentium - is this what you asked?

no machan not dat not pentium,im askin abt dore2duo and dual core

Higher IPC = more instructions can be executed per clock. I think it's twice as P-D.

Low latency cache = accessing cache is faster, not necessarily the cache is faster (cache runs at the same clock speed)

Higher FSB = 800MHz vs 1066MHz (or 1333MHz - Kentsfield/Conroe Refresh or 1600MHz - upcoming)

Branch Predictor = How successfully the answer to a conditional operation can be predicted

SSE engine = more SSE instructions (for multimedia tasks - more work per clock because of complex instructions) and higher SSE bus width

Micro and Macro fusion = certain operations can be combined together in one cycle. (such as assembly operations ADD, MOV etc.)

Prefetching = bring new instructions to the execution unit while the other instructions are already being processed (removes wait cycles)

Dual core is two Pentium Cores bundled together

ahhhhh..dats what i wanted

 

[Anusha]

ahhhhh..dats what i wanted

Damn!

 

[Novindu]

Damn!

ya damn i was so confused abt dat man

 

[geethq]

Shaaaa visthara goday!!

About what? Pentium and Dual Core?
PentiumD = Two Pentium4 (non-HT) cores (can execute two simultaneous threads)
Pentium Extreme = Two Pentium4 (HT) cores (can execute four simultaneous threads)

but all of dem havin a less technology dan c2d neda

 

[Anusha]

but all of dem havin a less technology dan c2d neda

Yes.

 

[Novindu]

Yes.

ela thx

WoW... IT Boz,,,

Nice Avator...

 

[GNS]

Then Core also contains P4 or P-D speeds (abt 2~3GHz) ne...

are they powerful than Pentium?

or How they work?

[amilabanuka]

Guyz i he'd about quad core today.
Anusha, what abt it? Four cores on die!!!!!
Is there any difference in cache in P-D and c2d?

1.86GHz Core2 Duo = 3.4GHz PentiumD in general = 4GHz+ PentiumD in games

 

[GNS]

1.86GHz Core2 Duo = 3.4GHz PentiumD in general = 4GHz+ PentiumD in games

Then Do 2 Processors act Separately?

I mean 1.86GHz works for one 1.86GHz & other Pros for other Work?
(I mean 1.86+1.86=3.32GHz?)
