Intel Celeron 847 vs Pentium D 820

Mini Review

Intel Celeron 847 advantages

  • On-chip Virtualization technology enhances performance of virtualized programs.
  • SSSE3, SSE4.1 and SSE4.2 instructions are enabled on this processor.
  • The Intel Celeron 847 has integrated HD (Sandy Bridge) GPU. While this graphics is not fast enough to run latest games with all settings on, it can be used for casual gaming and 3D apps.
  • The 847 is 82% more energy efficient than the Pentium D 820.

Intel Pentium D 820 advantages

  • The Intel Pentium D 820 comes with higher operating frequency than the Celeron 847 CPU.
  • The Intel Pentium D 820 uses Socket 775, and can be removed from it with ease. This allows easy processor upgrade or downgrade when desired.

847 vs 820 specifications comparison

The graphs below compare the most important features of the Intel 820 and Intel 847 processors. These characteristics, as well as an IPC (instructions per cycle) number, determine how well a CPU performs. Darker area on the "On-chip cache" graph is for the On-chip L2 cache. Lighter area is for the L3 cache cache. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
