Intel Atom Z3770 vs Core i3-4020Y

Mini Review

Intel Atom Z3770 advantages

  • More CPU cores on the Intel Z3770 help to process many simultaneous programs or threads.

Intel Core i3-4020Y advantages

  • Base frequency of the microprocessor is higher than the frequency of the Z3770.
  • The Intel Core i3-4020Y CPU includes AVX, AVX2 and FMA3 instructions, introduced in the recent past. While these extensions are not extensively used by applications yet, their support should improve in future programs.

Z3770 vs i3-4020Y specifications comparison

The charts below compare the most important i3-4020Y and Z3770 characteristics. These features, 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. The "Operating frequency" chart uses dark color to represent base frequency, whereas lighter area is for additional frequency, provided by Turbo feature. 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.
