Clock Speed ​​Wars Are Back As Intel Boasts It Has Hit 6GHz With 13th Gen CPUs


Intel is gearing up to launch the first products in its 13th-generation Core family of processors, codenamed Raptor Lake. One of the main facts announced by the company during its Intel Technology Tour is that at least one member of the Raptor Lake family will be able to reach 6 GHz from the start (via Tom’s Hardware). Core count and architectural improvements are usually more important than clock speed when it comes to increasing CPU performance these days, but after many years in the 5GHz range, it is good to reach the next digit.

As for what that means for performance, Intel says Raptor Lake will perform about 15% better in single-threaded tasks and 41% better in multi-threaded workloads than current 12th-gen Alder Lake chips. Clock speed is more important for improving single-threaded performance, while adding more cores is usually the best way to improve multi-threaded speeds.

It is not known which of the processors will be able to reach 6 GHz or under what circumstances or for how long. An Intel SKU graphic published by Igor’s Lab suggests the Core i9-13900K will hit 5.8GHz, though it’s possible it’s capable of going even higher.

A purported SKU chart for 13th-gen chips doesn't mention the 6GHz limit, but the boost works in mysterious ways.

The SKU chart also confirms what we heard from other leaks– despite an architectural similarity to current Alder Lake processors, Intel is improving performance by doubling the maximum number of E cores in its top-tier processors from eight to 16. The i5-12600K, which included four E cores, will also be replaced by a Core i5-13600K which includes eight. And if the rest of this leaked desktop CPU lineup is true, some low-end Core i5 CPUs that ship with Nope 12th Gen e-cores will get four or eight in 13th Gen.

This SKU chart also indicates that these high-end Raptor Lake processors will include other changes, including an increase in the amounts of L2 and L3 cache available. It also appears that the maximum turbo power consumption of all chips increases by 12W to 63W, from 241W to 253W for the Core i9, from 190W to 253W for the Core i7, and from 150W to 181W for the Core i5. The base power of all the chips remains stable, at 125 W.

These maximum power consumption figures do not necessarily mean that all Raptor Lake processors will consume more power than their Alder Lake counterparts, it will depend on the specific power settings your motherboard or PC manufacturer chooses to use. ‘utilize. This means that a Raptor Lake CPU with high power limits and adequate cooling will need more power and better cooling than a similarly configured Alder Lake CPU when running sustained workloads. .

People old enough to remember installing Windows 98 will recall that clock speed bragging rights were a big deal in the early 2000s. Intel was planning to boost its Pentium 4 processors from the 1 GHz midrange up to 10GHz by 2005, but the architecture was barely able to reach 4 GHz before the consumption of heat and electricity became so high that further increases became unsustainable (the the first attempt at a 4 GHz processor never saw the light of day).
