What Is the Difference Between a Pentium Duo Core & a Core 2 Processor?
- The clock speed--that is the rate at which the processor completes its main functions--of the Intel Pentium chips ranges from 1.6 gigahertz (GHz) to 3.06 GHz. The clock speed range of the Core 2 Duo chips is higher: at 1.8 GHz to 3.33 GHz.
- The bus speed--this is the rate of data transfer between the processor and the computer's motherboard--is rated at 800 megahertz (MHz) or 1,066 MHz for the Intel Pentium. The Core 2 Duo has some chips in its line-up that are faster, at 1,333 MHz.
- Each Intel Pentium and Core 2 Duo chip has a 64-bit instruction set and has Execute Disable Bit, a security-based feature to reduce malicious-code attacks and viruses. However, Core 2 Duo processors additionally have the Intel Trusted Execution Technology, which furthers the chip's security measures such as protection of data and protection against software-based attacks.
