최근에 Intel Core I7-5500U 노트북을 저렴하게 하나 샀는데, I7-6500U랑 비교해보면 DDR4를 사용한다는 것과 새로운 아키텍쳐라 좀더 빠를것으로 생각되는데... 실제 성능은 두가지를 이득을 고려해도 가격차이를 설명하기 너무 어려운 차이라 보여짐.

인텔 독점체제라 기술개발을 일부러 천천히 하는 느낌이랄까. Broadwell vs Skylake 인텔이 좀더 열심히 해줬으면 좋았을텐데...

Intel Core i7-5500U advantages

  • None

    Intel Core i7-6500U advantages

  • Operating frequency of this processor is higher than the frequency of the Core i7-5500U microprocessor.
  • The CPU officially supports faster DDR4-2133 memory, as such, it has higher memory bandwidth, which is quite beneficial to programs, that work with large data sets. Performance gains in non-memory bound tasks will be lower.


i7-5500U vs i7-6500U specifications comparison

The charts below compare the most important features of the i7-6500U and Intel i7-5500U CPUs. These characteristics, 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 for 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.
