The dual-core processors the number of cycles that a CPU can execute a task in a second is low. Whereas in the core 2 duo processor the CPU speed is faster which makes the core 2 duo run faster. Whenever there are instructions given to the processors, the instructions get accumulated in a pipeline and this is called the pipeline storage. A Core 2 Duo IS a Centrino dual core. i7 is generally the best of that bunch, followed by the i5 and i3 The i3 will be better than a C2D at same clock speed due to the newer architecture Performance. In comparison with previous processors, Dual core is better than all. Core 2 duo has better performance than Dual core as it has better overclock ability than Dual core. 03. Cache Memory. In Dual core processor we have 3 MB of L2 cache memory. In Core 2 Duo processor we have 6 MB of L2 cache memory. 04. Intel (except Core 2 Duo, Centrino Core 2 Duo, or Xeon), AMD (except 64 or x2 dual-core), VIA C4, Apple MacBook Pro are all i386 (32 bit) Intel Core 2 Duo, Centrino Core 2 Duo, and Xeon; AMD Athlon64/x2, Sempron64/x2, Duron64 are all x86_64 (64 bit processors that can run 32 or 64 bit applications) If you want to be sure then pass me the Yonah is the code name of Intel 's first generation 65 nm process CPU cores, based on cores of the earlier Banias (130 nm) / Dothan (90 nm) Pentium M microarchitecture. Yonah CPU cores were used within Intel's Core Solo and Core Duo mobile microprocessor products. SIMD performance on Yonah improved through the addition of SSE3 instructions and The Core 2 Duo should have no problem running this new reboot of the iconic franchise. Minimum Requirements: CPU: Dual core CPU (AMD Athlon64 X2 2.1 Ghz (4050+)/Intel Core 2 Duo 1.86 Ghz (E6300) この世代はCentrino Duo（デュアルコア）かCentrino（シングルコア）と、搭載されるプロセッサによって名称が変わる。また、一部のIntel Core 2もこれに含まれる。 これら第3世代のプラットフォームはNapa（ナパ）と呼ばれる。Core 2ではNapa64、Napa Refreshと呼ばれる。 Advanced-Smart-Cache * Like the Core Duo, the Core 2 Duo has shared level 2 cache and each core receives the same amount of cache. Intel doubled the bandwidth to the level 1 cache though. .
