hi

can any one tell me the difference in architecture of dual core and core-2-duo processor? which one is better?
plz reply to both the questions.

thnx

Short answer first: "dual‑core" just means two processor cores; it is not a single chip design. You can have dual‑core CPUs built from very different microarchitectures. That is why answers that simply say "Core 2 Duo is better" (as and suggested) are right in practice, but the architectural reasons matter when you compare specific chips. (hardwaresecrets.com)

Core 2 Duo (the Conroe family on the Core microarchitecture) is a specific Intel design that moved away from NetBurst. Conroe used a single‑die dual‑core layout with a larger, more unified L2 cache, a shorter pipeline and many microarchitectural improvements (branch prediction, execution resources, memory behavior) that raise instructions‑per‑clock (IPC) and drop power use. The result: much better performance per clock and lower heat than NetBurst parts. (anandtech.com)

Older NetBurst‑based dual‑core parts (Pentium D/Presler) were effectively two cores in one package, with separate L2 caches and long pipelines tuned for very high clocks; that approach produced higher TDP and lower IPC. Benchmarks and contemporaneous reviews show Conroe/Core 2 delivering large IPC and efficiency gains versus Pentium D. (tomshardware.com)

Practical takeaway: for that era choose a Core 2 Duo over a Pentium D. Also watch out for branding: some later "Pentium Dual‑Core" desktop parts were actually Core‑based but with reduced cache (check the exact E‑series model, cache, TDP and socket). If the goal is a modern usable machine, remember both families are very old now — consider platform compatibility and whether replacing motherboard+RAM makes more sense than swapping a decade‑old CPU.

Try intel.com then.

You are very rude.

The difference in architecture is well described at Intel.com.

Obviously Core-2 Duo is the better architecture.

ok i feel sorry for that. i should not say that.i m sorry for becoming rude.

That's fine.

On the architecture point - in my view, the architecture scope includes the software that can run. There's a good article here:
http://en.wikipedia.org/wiki/Intel_Core that describes the architectural differences.

What lies behind your original question?

thnx

duel core is first generation 2 core cpu's, then came core 2 duo,then came quad core .so if newer is better then core 2 duo is better than dual core
