available
  • The microprocessor includes AES instructions, used to accelerate AES encryption and decryption. The technology is beneficial if you need to protect your disk or network data.
  • This CPU features F16C, FMA3 and XOP instructions, that were introduced in modern processors not too far ago. These extensions are not widely used in programs yet, but their support should improve in future apps.
  • The processor has FMA4 instruction set extension enabled. The FMA4 technology is only available on AMD CPUs, thus not many software vendors may support it in the future.
  • The microprocessor is 74% more energy efficient than the Intel Core i3-2120 CPU.

Intel Core i3-2120 advantages



Intel Core i3-2120
  • The microprocessor includes Hyper-Threading feature, which allows each CPU core to execute two threads simultaneously.
  • The Core i3-2120 processor offers higher operating frequency than the A6-4455M.
  • The CPU uses Socket 1155. The processor can be removed from the socket without trouble for upgrade or replacement.

A6-4455M vs i3-2120 specifications comparison

The graphs below compare the most important Intel Core i3-2120 and AMD A6-4455M characteristics. These features, along with an IPC (instructions per cycle) number, determine how well a microprocessor 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, provided by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent base frequency, whereas lighter area is for extra 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.
