The Ryzen 5 1500X has four physical cores plus SMT, 3.5GHz base clock, 3.7GHz turbo frequency, and 16MB 元 cache. The Core i5 8400 sits in price between the Ryzen 5 1500X and Ryzen 5 1600. There's also 3MB more of the 元 / Smart Cache and the native DDR4-2666 support rather than DDR4-2133. 3.0GHz, but a higher turbo frequency of up to 3.8GHz rather than 3.5GHz. The i5-8400 has a 9MB 元 cache size and has a 65 Watt TDP while its MSRP is $182 USD.Ĭompared to the non-refreshed Kabylake Core i5 7400, the Core i5 8400 has the two extra CPU cores, slightly lower base frequency of 2.8GHz vs. The Core i5 8400 processor being benchmarked in this article has its six cores clocked at 2.8GHz while having a single-core boost frequency of 4.0GHz or 3.8GHz boost across its six cores. Also practical is the complete Coffee Lake line-up now supports dual channel DDR4-2666 memory natively. The Core i3 Coffeelake processors meanwhile are four core, compared to previous generations being dual-core. Core i7 CPUs are also up to six cores while having Hyper Threading to yield 12 threads.

With Coffee Lake, the Core i5 parts are now at six cores. Today we will be featuring Linux benchmarks of the Core i5 8400 and Core i7 8700K while this article is focusing on the i5-8400: a six-core Core i5!Ĭore i5 processors have traditionally been quad-core CPUs without Hyper Threading. While a CPU refresh may not normally be too exciting, thanks to the pressure from AMD with their Ryzen processors pushing core counts higher, Intel is now upping the core counts in their desktop CPUs.

Today marks the embargo expiry for reviews on Intel's new Coffeelake desktop processors.
