Intel Core i5-4670K vs Intel Core i5-3570K

The Intel Core i5-4670K is based on the Haswell-S architecture and is an Intel desktop processor designed for mainstream users with overclocking intentions.

The Intel Core i5-3570K, part of the Ivy Bridge-S architecture, also targeted a similar audience and allowed overclocking.

Both CPUs are manufactured using a 22nm process, feature four physical cores without Hyper-Threading, allowing them to process four threads simultaneously, and possess 6 MB of Level-3 cache. They use PCIe 3.0 for connecting expansion cards and offer a maximum memory bandwidth of 26 GB/s. In performance tests, the Intel Core i5-4670K shows noticeably higher single-core performance than the Intel Core i5-3570K, due to architectural improvements of the Haswell generation.

The Intel Core i5-4670K also significantly surpasses its predecessor in multi-core performance, which is noticeable in demanding applications. This performance increase leads the Intel Core i5-4670K to generally deliver better frame rates in gaming scenarios. Its integrated graphics solution, the Intel HD Graphics 4600, is also more powerful than the Intel HD Graphics 4000 of the Intel Core i5-3570K, although a dedicated graphics card is usually used for demanding gaming.

Regarding power consumption and Thermal Design Power (TDP), both processors are comparable. In the secondary market, the Intel Core i5-4670K, assuming similar prices, offers a better price-performance ratio due to its superior performance. The Intel Core i5-4670K is the more recommendable choice for tasks that benefit from higher computing power, while the Intel Core i5-3570K provides a solid basis for less demanding applications in existing systems.
