The i5-8400 is a competitively priced hex-core processor from Intel’s 8th generation of Core processors (Coffee Lake). Along with the release of the unlocked i5-8600K, this is the first time that six-core processors have featured in the i5 line-up. Like the other Coffee Lake processors, the i5-8400 is based upon an improved version of Intel’s 14nm architecture which featured in both Skylake and Kaby Lake. Early benchmarks reveal that for average quad core usage (most games employ a maximum of four cores) the i5-8400 performs way above its pay grade. It achieves quad core mixed speeds close to Intel’s outgoing 2017 flagship the $300, quad-core, 8 thread i7-7700k, which to date has been a strong favourite for high-end gaming setups. On paper, the i5-8400 has a base clock of 2.8 GHz (Intel are significantly downplaying the performance of this SKU by giving it a relatively low nominal base clock), an all core boost of 3.8 GHz (this is the effective base clock figure that counts) and a single core boost of 4 GHz. This compares reasonably well to the i5-8600K which has a base clock of 3.6 GHz, all core boost of 4.1 GHz and a single core boost of 4.3 GHz. The i5-8400 also features 9MB of L3 cache and an energy-thrifty TDP of 65W. Priced at under $190, the i5-8400 offers fantastic value for money. Unfortunately, like the other Coffee Lake processors, the i5-8400 will require a new 300 series motherboard, and at the time of writing, the only available version is Intel’s high-end Z370 which isn't an ideal pairing for the i5-8400. The Z series motherboards are designed to cater for the unlocked and overclockable "K" SKUs. Cheaper 300 series motherboards will be available in 2018 at which time the 8400 will offer even better value for money. [Oct '17 CPUPro]

The Raptor Lake Intel i5-13400F ($200 USD, cooler included) paired with a B660/B760 motherboard ($150 USD) and 2x8 GB DDR4 3600 RAM ($50 USD) offers good value for money to mid-range gamers. The 13400F has around 5% higher single-core and 35% higher multi-core performance than its predecessor. Although both processors feature the same Golden Cove p-cores, the 13400F has four additional energy efficient e-cores which account for the improvement in multi-core performance. The 13400F offers comparable gaming and better multi-core performance than AMD's 7600X but at a lower price and without the need for an aftermarket cooler, DDR5 memory and an expensive motherboard. Since Intel don’t care for long term relationships with PC hardware influencers, for product launches, they often end up sponsoring influencers that are mostly funded by AMD. As a result, Intel rarely get positive marketing coverage beyond launch, and their products remain relatively under priced compared to AMD. When paired with a DDR4 motherboard the 13100F/13400F CPUs (at MSRP) offer unbeatable/good value to entry/mid level PC gamers. High end gamers should investigate the 13600K, which thanks to both higher clocks and higher IPC (Raptor Cove), is around 15% faster than the 13400F. [Jan '23 CPUPro]

 Frequently Asked Questions

 Best User Rated

Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
