Intel Core i5-2400 vs Intel Core Ultra 7 265

The Intel Core i5-2400 (Q1 2011) was a mainstream processor for basic tasks. Manufactured using the 32-nm process (Sandy Bridge S) with 4 cores/4 threads and 6 MB Level 3 cache, it offered Intel HD Graphics 2000, PCIe 2.0, and 21 GB/s memory bandwidth.

The Intel Core Ultra 7 265, based on the 3-nm Arrow Lake architecture, is a modern processor for demanding applications.

Its hybrid architecture includes more cores/threads, 36 MB Level 2, and 33 MB Level 3 cache. The integrated Intel Xe 4 Core Graphics (Arrow Lake) and PCIe 5.0 with 102 GB/s memory bandwidth are more powerful. In terms of performance, the Intel Core Ultra 7 265 significantly outperforms the Intel Core i5-2400 in single- and multi-core performance.

For gaming and compute-intensive tasks, the newer processor is far superior, making the Intel Core i5-2400 unsuitable for modern games. Thanks to its 3-nm process, the Intel Core Ultra 7 265 is more energy-efficient than the 32-nm Intel Core i5-2400, whose TDP is higher relative to its performance.

The Intel Core i5-2400 is only relevant today as an inexpensive used part; the Intel Core Ultra 7 265 offers superior value for money as a new purchase. In summary, the Intel Core i5-2400 is outdated; the Intel Core Ultra 7 265 is superior in all respects and the clear recommendation for modern applications.
