Intel Core i5-6400 vs Intel Core i5-7500

The Intel Core i5-6400, based on the Skylake-S architecture, and the Intel Core i5-7500, part of the Kaby Lake-S generation, are both designed for the mainstream desktop market.

They target users who need reliable performance for general computing tasks and light productivity. Both processors are manufactured using the 14nm fabrication process and feature 4 cores and 4 threads. They support PCIe 3.0 and have 6 MB of Level 3 Cache. The Intel Core i5-6400 integrates the Intel HD Graphics 530 with a maximum memory bandwidth of 34 GB/s.

The Intel Core i5-7500 offers the improved Intel HD Graphics 630 and a higher maximum memory bandwidth of 38 GB/s. In terms of single-core and multi-core performance, the Intel Core i5-7500 consistently shows significantly higher performance than the Intel Core i5-6400, with differences well over 10 percent in relevant benchmarks.

This performance increase is due to architectural improvements of the Kaby Lake-S generation. For gaming scenarios, the Intel Core i5-7500 offers better performance. Its superior core performance and the slightly more powerful integrated graphics unit, Intel HD Graphics 630, contribute to smoother gaming experiences, especially in games that benefit from higher single-core performance.

Information on Thermal Design Power (TDP) or exact power consumption is not available in the provided data. However, due to similar manufacturing and core count, it can be assumed that both processors operate within a comparable energy efficiency range. Since current market prices are not available, the price-performance ratio can only be evaluated based on raw processing power.

Here, the Intel Core i5-7500 offers a better ratio due to its significantly higher performance. The Intel Core i5-6400 would only be worth considering if it were available at a substantially lower price and performance requirements are low. In summary, the Intel Core i5-6400 is a solid option for basic tasks and budget-conscious users.

The Intel Core i5-7500, on the other hand, is the better choice for overall more responsive system performance, smoother multitasking, and improved capabilities in light gaming and more demanding applications.
