Intel Atom S1260 vs Pentium III 500 MHz

Mini Review

Intel Atom S1260 advantages

  • More CPU cores on the Intel Atom S1260 help to tackle multiple programs or heavily multi-threaded tasks.
  • This microprocessor integrates Hyper-Threading feature. This technology doubles the number of threads that the processor can run at once.
  • Operating frequency of the CPU is higher than the frequency of the Pentium III 500 MHz.
  • Execute disable bit feature on this processor helps to protect from certain types of computer viruses. This technology does not work on old OSes, such as Windows 2000, MAC OS 9, and earlier ones.
  • The Atom S1260 has Intel 64 feature, that allows it to run 64-bit operating systems.
  • The Intel Atom S1260 microprocessor provides hardware acceleration of virtualized programs.
  • SSE2 instructions, supported by this cpu, are used by many modern applications.
  • The Atom S1260 processor supports SSE3 and SSSE3 instructions.

Intel Pentium III 500 MHz advantages

  • The CPU works in Slot 1. The processor can be effortlessly removed from the socket for replacement or upgrade.

Atom S1260 vs Pentium III 500 MHz specifications comparison

The charts below compare the most important characteristics of the Intel Pentium III 500 MHz and Atom S1260 microprocessors.
