Intel Core i7-4790K vs Intel Core i7-5775C

The Intel Core i7-4790K, architectural name Devils Canyon S, was introduced in mid-2014 for enthusiasts and overclockers.

Manufactured using the 22 nm process, it offers 4 cores and 8 threads, 8 MB of Level 3 Cache, and PCIe 3.0. The integrated graphics are the Intel HD Graphics 4600. In pure computing performance, it shows a slight advantage in some single-core tests, while multi-core performance is solid. Its main strength lies in its overclocking potential.

The Intel Core i7-5775C, architectural name Broadwell S, came onto the market in mid-2015, aiming for improved graphics performance and efficiency.

Manufactured using the more modern 14 nm process, it also has 4 cores and 8 threads, 6 MB of Level 3 Cache, and PCIe 3.0. Its strength is the Intel Iris Pro Graphics 6200 with eDRAM, which offers significantly higher graphics performance than the 4790K. In newer single-core and multi-core tests, it can show slight advantages.

In a performance comparison, both processors are very similar in pure CPU performance for most applications. The Intel Core i7-4790K offers a slight lead in some single-core scenarios. The Intel Core i7-5775C benefits from its 14 nm manufacturing process, which potentially allows for better energy efficiency.

For gaming with a dedicated graphics card, the differences are minimal. For systems without a separate graphics card or with a focus on compact design, the Intel Core i7-5775C with its significantly stronger Iris Pro Graphics 6200 is the clear choice. The availability of both processors is limited to the used market.
