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 i7-5820K is the cheapest of three (5820K,5930K,5960X) new Haswell-E prosumer/enthusiast processors. The 5820K sports six physical cores and twelve threads which allow for enormous processing throughput. Unfortunately Intel have somewhat handicapped the 5820K by setting its base clock at just 3.3 GHz, 0.7GHz lower than the class leading 4790K. Comparing the 4790K and 5820K shows that the cheaper i7-4790K is significantly faster at both single and dual threaded workloads. The additional two cores found in the 5820K are not relevant to general computing and as such the 5820K probably makes a better server rather than consumer proposition. The Haswell-E X99 architecture also requires DDR4 RAM which is currently far more expensive than DDR3. Overall the 5820K is a very expensive option and probably best avoided by the vast majority of consumers.  [Sep '14 CPUPro]
