Intel Core i5-12400 vs Intel Core i7-9700

The Intel Core i7-9700, introduced in 2019 as part of the 9th generation (Coffee Lake S Refresh), targeted the mainstream desktop market.

It is manufactured using a 14nm process and features 8 cores without Hyper-Threading (8 threads) with 12 MB of L3 cache. Its integrated Intel UHD Graphics 630 and PCIe 3.0 with a maximum memory bandwidth of 43 GB/s characterize this CPU, which offered solid performance for its time. The Intel Core i5-12400, released in 2022 as part of the 12th generation (Alder Lake S), also aims at the mainstream segment, but with a significantly more modern foundation.

It is manufactured using the more efficient 10nm process (Intel 7) and features 6 cores with Hyper-Threading (12 threads), 8 MB of L2 cache, and 18 MB of L3 cache. The Intel UHD Graphics 730 and support for PCIe 5.0 with 77 GB/s memory bandwidth are significant advancements. In terms of performance, the Intel Core i5-12400 noticeably outperforms the Intel Core i7-9700, in both single-core and multi-core performance.

The newer Alder Lake S architecture ensures higher efficiency and processing capability. For gaming purposes, the Intel Core i5-12400 offers a better experience thanks to its superior single-core performance and support for PCIe 5.0. Both CPUs have a base TDP of 65W. However, the Intel Core i5-12400 achieves higher performance per watt due to its more advanced manufacturing process.

For new systems, the Intel Core i5-12400 offers a more compelling price-performance ratio. The Intel Core i7-9700 is primarily relevant for cost-effective upgrades of older, compatible platforms.
