The leaked benchmarks, revealed by Twitter user @wxnod reveal an18 percent performance boost in CPU-Z's multi-threaded benchmark over the Core i7-13700K. This would probably be down to the rumored increased core count amd expected higher frequencies.

The single-thread performance rises a less impressive four percent as it's not impacted by the core count increase, but this could have an impact in game performance. the other benchmark listed was Cinebench. Here the single-thread performance increased over four percent while the multi-threaded performance increased by nearly 17 percent.

The Core i7-14700K is better than the Ryzen 9 7950X3D in the multi-threaded score and sits below only the Core i9-13900K and Ryzen 9 7950X adding nearly 9,000 points to the score of the Ryzen 9 7900X - a huge advantage.

In the single-thread test, the Core i7-14700K sits second to the Core i9-13900K, with an impressive uplift over the Core i7-13700K. 

The Intel Core i7-14700K is rumored to have a total of 20 cores, which is an increase of four cores over the Core i7-13700K despite the two CPUs using the same architecture. Specifically, YouTuber Moore's Law is Dead claims that the additional cores will be part of the CPU's E-cores or efficient cores, which assist in multi-threaded workloads and background tasks.

The new CPUs will be compatible with existing LGA1700 socket motherboards including those with Z690, B660, Z790 and B760 chipsets, but may require a BIOS upgrade. So called 14th Gen Raptor Lake refresh CPUs are being launched instead of a new socket and Meteor Lake CPUs for desktop PCs, which have been delayed indefinitely, although these are still launching in mobile devices such as laptops in the autumn.
