  • The microprocessor has SSE4.1 and SSE4.2 instructions.

N2800 vs 847 specifications comparison

The charts below compare the most important Intel 847 and Intel N2800 features. These characteristics, together with an IPC (instructions per cycle) number, determine how well a processor performs. The "Number of cores / threads" graph shows the number of cores (darker area). Lighter area on the graph corresponds to the number of extra threads, provided 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. While the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
