The company said in a statement on Wednesday that these benchmarks had been measured in real-world workflows over competitive products.
The biggest American chip company by revenue, Intel's new Tiger Lake line is built using 10-nanometre chipsets.
The company said in July that it had been forced to delay the introduction of 7nm CPUs as it had no economically viable way to produce them right away and the release would be delayed for at least six months.
Intel said more than 150 designs based on the new processors were expected from companies such as Acer, ASUS, Dell, Dynabook, HP, Lenovo, LG, MSI, Razer and Samsung.
“11th Gen Intel Core processors with Intel Iris X graphics are a major leap forward in real-world processor performance and are the best laptop processors we have built,” said Gregory Bryant, Intel executive vice-president and general manager of the Client Computing Group.
“From productivity and content creation to entertainment and gaming, when you pick a system powered by 11th Gen Intel Core – especially one of our new Intel Evo co-engineered and verified designs – you know you are getting the best laptop experience possible.”
Intel said the Tiger Lake line was the best processor "for thin-and-light laptops with unmatched capabilities for real-world productivity, collaboration, creation, gaming and entertainment across Windows and ChromeOS-based laptops". Nothing was said about performance under Linux.
“The new 11th Gen Intel Core processors with Iris X graphics are delivering incredible performance and responsiveness to enable Windows customers around the world to be more productive and have fun today and in the future,” said Panos Panay, chief product officer at Microsoft.
John Solomon, vice-president of ChromeOS, added: “Based on extensive and deep collaboration between Intel and Google, we’re able to optimise the user experience, and we are thrilled to be bringing the next generation of Chromebooks to market powered by 11th Gen Intel Core.”
