AMD A8-4555M advantages

  • The A8-4555M includes more CPU cores than the Core i5-3317U. Large number of cores helps this processor to tackle multiple applications or heavily multi-threaded programs.
  • The CPU has FMA3 and XOP instructions. These extensions are not broadly used by applications yet, however their support should improve in future apps.
  • The A8-4555M supports FMA4 instruction set extension. Only AMD CPUs have this technology, therefore not many software vendors may support it in the future.

Intel Core i5-3317U advantages

  • Operating frequency of the Core i5-3317U is higher than the frequency of the AMD A8-4555M processor.
  • The microprocessor is 11% more energy efficient.

A8-4555M vs i5-3317U specifications comparison

The charts below compare the most important i5-3317U and AMD A8-4555M characteristics. These features, along with 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 represents the number of additional threads, offered by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent base frequency, while 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.
