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 Intel Core 2 Duo E8400 is amongst the fastest of the Core 2 Duo range of now nearly ten year old CPUs. The E8400 is included in our group tests simply as a reference point due to its huge success back in its day. Running at a clock speed of 3.0 GHz the E8400 has an effective speed of 52 which is 85% slower than its modern day counterparts. The relative lack of performance is especially noticeable in the area of multi-core processing as a consequence of the E8400's relatively few two cores. Anyone considering an upgrade needn't hesitate as modern CPUs are not only orders of magnitude faster but also considerably more energy efficient and feature packed. [Oct '14 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
