Intel Atom N455 vs Celeron 877

Mini Review

Intel Atom N455 advantages

  • Operating frequency of the CPU is higher than the frequency of the 877.
  • Power consumption of the microprocessor is lower.

Intel Celeron 877 advantages

  • The Intel 877 has more processing cores than the Atom N455. Large number of cores helps this microprocessor to process multiple applications or heavily multi-threaded tasks.
  • Incorporated Virtualization technology improves performance in virtualization applications.
  • The 877 processor has SSE4.1 and SSE4.2 instructions enabled.

N455 vs 877 specifications comparison

The graphs below compare the most important Intel Celeron 877 and Intel N455 characteristics. These features, as well as an IPC (instructions per cycle) number, determine how well a processor performs. The "Number of cores / threads" graph displays the number of cores (darker area). Lighter area on the graph corresponds to the number of additional threads, offered by Hyper-Threading technology. 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.
