Intel Atom D525 vs Core i7-3517U

Mini Review

Intel Atom D525 advantages

  • The microprocessor has 24% lower power consumption than the i7-3517U CPU.

Intel Core i7-3517U advantages

  • This microprocessor offers higher operating frequency than the Intel Atom D525.
  • The Core i7-3517U CPU supports Virtualization feature, that enhances performance in virtualization tasks.
  • The processor has SSE4.1 and SSE4.2 instructions enabled.
  • The Intel Core i7-3517U features AES, or Advanced Encryption Standard, technology. This extension provides hardware acceleration of AES encryption and decryption, and is valuable if you run applications, that secure your disk or network data.
  • The CPU has AVX and F16C instructions enabled. Even though these extensions are not broadly used by programs yet, their support should improve in future applications.

D525 vs i7-3517U specifications comparison

The charts below demonstrate the difference between Intel Core i7-3517U and D525 most important characteristics. These features, along with 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, 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.
