Intel Core i5-2500k vs Intel Core i7-3770

The Intel Core i5-2500k and the Intel Core i7-3770 are desktop processors for different performance requirements.

The Intel Core i5-2500k is based on the Sandy Bridge S architecture and was intended for overclocking enthusiasts. The Intel Core i7-3770 uses the newer Ivy Bridge S architecture for higher performance and efficiency. The Intel Core i5-2500k was manufactured using the 32 nm process and offers 4 cores / 4 threads with 6 MB of Level 3 Cache.

In contrast, the Intel Core i7-3770 uses the finer 22 nm process and features 4 cores / 8 threads thanks to Hyper-Threading, as well as 8 MB of Level 3 Cache. The maximum memory bandwidth is 21 GB/s for the Intel Core i5-2500k and 26 GB/s for the Intel Core i7-3770.

In benchmarks, the Intel Core i7-3770 shows significantly higher performance of over 10 percent in both single-core and multi-core tasks. This makes it a better choice for demanding applications. For gaming, the Intel Core i7-3770 also offers better performance due to the newer architecture, Intel HD Graphics 4000 (compared to Intel HD Graphics 3000), and support for PCIe 3.0 (compared to PCIe 2.0).

Due to the smaller manufacturing process, the Intel Core i7-3770 is more energy-efficient, leading to lower power consumption and heat generation. In the used market, the price/performance ratio depends on the specific offer, with the Intel Core i7-3770 generally offering more performance.
