Intel Core i7-3770K vs Intel Core i3-8100

The Intel Core i7-3770K was introduced in 2012 as a high-end processor for desktop enthusiasts. Based on the Ivy Bridge S architecture and manufactured using the 22 nm process, it offers 4 cores and 8 threads through Hyper-Threading.

It features 8 MB of Level 3 Cache, supports PCIe 3.0, and achieves a maximum memory bandwidth of 26 GB/s. Its single-core and multi-core performance was good for its generation but has been surpassed by newer architectures. The integrated graphics unit is the Intel HD Graphics 4000. As an overclockable processor, it may exhibit higher power consumption when overclocked.

The Intel Core i3-8100, part of the Coffee Lake S architecture, was released in 2017/2018 and targeted the entry-level to mainstream desktop segment.

It is manufactured using a more advanced 14 nm fabrication process and has 4 cores without Hyper-Threading, thus 4 threads. This processor offers 6 MB of Level 3 Cache and also supports PCIe 3.0, with a maximum memory bandwidth of 38 GB/s. Thanks to its newer architecture and higher IPC, the Intel Core i3-8100 demonstrates significantly superior single-core and multi-core performance compared to the Intel Core i7-3770K.

The integrated graphics unit is the Intel UHD Graphics 630. The 14 nm manufacturing process also indicates better energy efficiency. For gaming scenarios, the Intel Core i3-8100 offers more advantageous performance due to its higher IPC. Both processors are older models mainly available on the used market.

Overall, the Intel Core i3-8100 provides superior performance for most modern applications and games. The Intel Core i7-3770K is better suited for older systems or specific overclocking projects.
