Intel Core i5-6400 vs Intel Core Ultra 5 225

The Intel Core i5-6400 is based on the Skylake S architecture and was developed for mid-range desktop users.

It is manufactured using a 14-nanometer process. In contrast, the Intel Core Ultra 5 225 uses the Arrow Lake architecture and is produced in an advanced 3-nanometer process.

In terms of computing power, benchmarks show significant differences. The Intel Core Ultra 5 225 achieves values in both single-core performance and multi-core scenarios that exceed the Intel Core i5-6400 by far more than ten percent. This lead results from the optimized architecture and increased core count.

While the Intel Core i5-6400 has 6 MB of Level 3 cache, the newer model offers significantly more data processing capacity with 26 MB of Level 2 and 24 MB of Level 3 cache. In gaming scenarios, the Intel Core Ultra 5 225 operates much more effectively. The integrated Intel Xe 4 Core Graphics 64 EUs offers higher graphical performance than the Intel HD Graphics 530 of the Intel Core i5-6400.

In addition, the memory bandwidth of 102 GB/s for the Intel Core Ultra 5 225 ensures faster data exchange compared to the 34 GB/s of the other model. Support for PCIe 5.0 compared to PCIe 3.0 on the Intel Core i5-6400 is also a relevant factor for system speed. Regarding power consumption and thermal design, the Intel Core Ultra 5 225 is optimized for high efficiency.

The price-performance ratio of the Intel Core Ultra 5 225 is superior for current requirements, making this processor the recommendation for modern systems.
