AMD E-Series E-300 vs Mobile Sempron SI-42

Mini Review

AMD E-Series E-300 advantages

  • More CPU cores on the E-300 help to handle many programs or threads at once.
  • The processor provides hardware acceleration of virtualized applications.
  • SSSE3 instructions are enabled on this microprocessor.
  • The CPU has on-chip Radeon HD 6310 graphics. This GPU is not fast enough to play latest games with all settings on, but it can be used for casual gaming and 3D apps.
  • Power consumption of the E-300 is better.

AMD Mobile Sempron SI-42 advantages

  • The microprocessor offers higher operating frequency than the AMD E-300 CPU.
  • The microprocessor supports 3DNow! instructions. The 3DNow! instruction set helps the processor to execute certain floating-point operations faster, and thus enhance performance in games and software, that support the instructions. These instruction are obsolete now, and only some old games and software used them.
  • The CPU utilizes Socket S1 (S1g2). The microprocessor can be removed from the socket without trouble for replacement or upgrade.
