Intel’s 13th gen. Raptor Lake CPUs offer around 10% faster gaming and 45% faster multi-core performance than their predecessors. The new CPUs are compatible with DDR4 memory and Z690/B660 ($150) motherboards. New high-end gaming builders need look no further than the 13600K. The 13600K beats AMD’s flagship 7950X in gaming and almost matches the 7900X in multi-core performance. Extreme workstation users may find value in the 13700K or 13900K. Gamers on a tight budget can save $40 USD with a 13600KF which is a 13600K without integrated graphics. Although Ryzen 7000 has weaker multi-core, weaker single-core, higher platform costs and higher unit prices AMD have a 3D joker up their sleeve (7800X3D est. 2023). Via “Advanced Marketing” on youtube, forums, reddit, and twitter AMD will demonstrate that their upcoming CPU is the “best in the world” and offer “proof” by way of a small handful of obscure workloads. Games that few people play e.g. (Factorio, SotTR) will be cherry picked, video footage of the gameplay/settings won’t be provided and frame drops will be conveniently ignored. This playbook has easily outsold Intel in recent years but with every overhyped release, consumers lose trust in AMD. Based on social media/press coverage, you would never guess that the combined market share for all of AMD’s Radeon 5000 and 6000 GPUs amongst PC gamers is just 2.12% (Steam stats). Meanwhile Nvidia’s RTX 2060 alone accounts for a whopping 5.03%. Largely thanks to marketing incompetence, Intel is existentially motivated to deliver material annual performance improvements. Consumers can look forward to Meteor Lake (14th gen) in less than a years time. [Oct '22 CPUPro]

MORE DETAILS

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]

 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.
