AMD A6-4455M vs Intel Pentium 2127U

Mini Review

AMD A6-4455M advantages

  • Operating frequency of the AMD A6-4455M is higher than the frequency of the Intel Pentium 2127U processor.
  • The A6-4455M incorporates AES instructions, used to accelerate AES encryption and decryption. The instructions are valuable if you need to protect your disk or network data.
  • The CPU has AVX, F16C, FMA3 and XOP instructions, that were introduced in the recent past. Even though these extensions are not widely used in applications yet, their support should improve in future programs.
  • FMA4 instruction set extension is enabled on this microprocessor. The FMA4 technology is only available on AMD microprocessors, thus not many software vendors may support it in the future.

A6-4455M vs 2127U specifications comparison

The graphs below compare the most important characteristics of the 2127U and AMD A6-4455M processors. These features, along with an IPC (instructions per cycle) number, determine how well a processor performs. The "Operating frequency" chart uses dark color for base frequency, while 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.
