Core Duo 

Intel's dual-core successor to the Pentium M. Previously codenamed Yonah, the Core Duo is a processor designed specifically around performance-per-watt - in other words, trying to produce an energy-efficient CPU that does not compromise severely on speed. As such, it has replaced the PowerPC G4 processor in Apple's Powerbooks (now called MacBook Pro) as part of Apple's widely-acclaimed switch to Intel processors and the X86 architecture. Core Duos will also be used by major computer manufacturers in their laptops, and can also be found in Apple's new iMac Core Duo.

The Core Duo will soon be replaced (Q4 of 2006) by Intel processors Conroe and Merom, which will be 64-bit chips with similar energy savings as the Core Duo but boasting more cache, improved performance and less heat production.

My MacBook Pro with Core Duo processor total smokes your PowerPC G4.
(second person) Yeah, but I don't need to emulate PPC apps in Rosetta!

core 2 duo 

New processor line developed by Intel Corporation. Based on the P6 and P4 Mobile architectures, it outperforms the AMD competition at a lower price point. It features more effecient instruction decoding, larger cache, a higher FSB, and a higher IPC, all while producing less heat.

Person one: d00d I just got a new Athlon64 5000+ for only 800$
Person two: n00b you should have bought a Core 2 Duo.

intel core 2 duo 

The newest member of the Intel processor family. Codenamed "Conroe", it was quite possibly the most anticipated processor launch in history. Core 2 Duo marks the retirement of the "Pentium" brand that has been Intel's flagship brand since 1993, and the streamlining of Intel's desktop and mobile product lines. Based on a hybrid Pentium M/Pentium 4 architecture, Core 2 Duo and its adherent, the Core 2 Extreme are both dual-core processors that use approximately 40% less power than the Pentium D, and run much cooler than their predecessors. Benchmarks from various enthusiast review sites have shown the Core 2 Duo/Extreme's performance surpasses that of AMD's high-performance chip, the FX-62. All Core 2 Duo/Extreme processors run on a 1066 Mhz front side bus, have 4 MBs of L2 Cache (the exception being the E6300 and E6400 models, which feature 2MBs of L2 Cache), and use the LGA775 socket already in use by the Pentium 4/D/Extreme. With a quad-core iteration of the Core 2 Duo on the horizon, codenamed Kentsfield, to be released at the end of this year, the future is looking pretty bright for Intel.

I have an Intel Core 2 Duo E6700 that will make your FX-62 cry.

Core 2 Duo 

An actually pretty decent processor found in many store-bought PCs. Technically out of date, but hasn't been replaced yet as Intel's making too much dang money to give up the 'ol front side bus.

1) Person 1: "What kind of processor does it have?"
Person 2: "A 2.2GHz Core 2 Duo."

2) Intel sticker: "Intel Core 2 Duo Inside"

3) "Only 800MHz FSB? What the h*ll, Intel?"
