AMD A8-3850 vs Intel Core i7-3940XM

Mini Review

AMD A8-3850 advantages



AMD A8-3850
  • 3DNow! technology is supported by this processor. The 3DNow! technology allows the CPU to execute certain floating-point operations faster, and thus boost performance in games, that support the instructions. These instruction are obsolete now, and only some old games and software used them.
  • Based on current official prices, the A8-3850 is 92% cheaper.

  • One of the distinctive features of the processor is Hyper-Threading technology, which allows this microprocessor to process twice as many threads.
  • Operating frequency of the Intel Core i7-3940XM is higher than the frequency of the A8-3850 processor.
  • The i7-3940XM CPU has SSSE3, SSE4.1 and SSE4.2 instructions.
  • The Core i7-3940XM includes AES technology, that accelerates AES encryption. The technology is beneficial if you need to protect your disk or network data.
  • The microprocessor incorporates AVX and F16C instructions, introduced in the recent past. Even though these extensions are not broadly used by applications yet, their support should improve in future programs.
  • The Intel Core i7-3940XM is unlocked. The processor can be freely overclocked on some motherboards to achieve better performance.
  • The Intel Core i7-3940XM is 45% more energy efficient.

A8-3850 vs i7-3940XM specifications comparison

The graphs below compare the most important Intel i7-3940XM and AMD A8-3850 characteristics. These features, as well as an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Number of cores / threads" graph shows the number of cores (darker area). Lighter area on the graph corresponds to 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.
