The clock pace wars are again as Intel brags about hitting 6 GHz with Thirteenth-gen CPUs

The clock speed wars are back as Intel brags about hitting 6 GHz with 13th-gen CPUs


Intel is gearing as much as launch the primary merchandise in its Thirteenth-generation Core processor household, codenamed Raptor Lake. Among the many topline details that the corporate introduced at its Intel Expertise Tour is that no less than one member of the Raptor Lake household can be able to hitting 6 GHz out of the field (through Tom’s {Hardware}). Core counts and architectural enhancements are typically extra necessary than clock pace in the case of growing a CPU’s efficiency as of late, however after a few years hanging out within the 5 GHz vary, it is neat to hit the following digit.

As for what this implies for efficiency, Intel is saying that Raptor Lake will carry out roughly 15 p.c higher in single-threaded duties and 41 p.c higher in multi-threaded workloads than the present Twelfth-generation Alder Lake chips. Clock pace is extra necessary for reinforcing single-threaded efficiency, whereas including extra cores is normally one of the best ways to enhance multi-threaded speeds.

It is not clear which of the CPUs can be able to hitting 6 GHz or below what circumstances or for a way lengthy. An Intel SKU chart revealed by Igor’s Lab means that the Core i9-13900K will prime out at 5.8 GHz, although it is potential that it is able to additional boosting past that.

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

The SKU chart additionally confirms what we have heard from different leaks—regardless of an architectural similarity to present Alder Lake CPUs, Intel is boosting efficiency by doubling the utmost variety of E-cores in its top-tier CPUs, from eight to 16. The i5-12600K, which included 4 E-cores, may even get replaced by a Core i5-13600K that features eight. And if the remainder of that leaked desktop CPU lineup holds true, some lower-end Core i5 processors that shipped with no E-cores within the Twelfth technology will get 4 or eight within the Thirteenth technology.

This SKU chart additionally signifies that these top-end Raptor Lake CPUs will embody different adjustments, together with elevated quantities of L2 and L3 cache out there. It additionally appears to be like just like the Most Turbo Energy consumption of all of the chips goes up by between 12 W and 63 W—from 241 W to 253 W for the Core i9, from 190 W to 253 W for the Core i7, and from 150 W to 181 W for the Core i5. The bottom energy for all of the chips stays degree, at 125 W.

These most energy consumption numbers do not essentially imply that each one Raptor Lake CPUs will eat extra energy than their Alder Lake counterparts—that may rely upon the particular energy settings that your motherboard or PC producer chooses to make use of. It does imply {that a} Raptor Lake CPU with excessive energy limits and satisfactory cooling will want extra energy and higher cooling than a equally configured Alder Lake CPU when operating sustained workloads, although.

Folks sufficiently old to recollect putting in Home windows 98 will recall that clock pace bragging rights have been an enormous deal within the early 2000s. Intel deliberate to spice up its Pentium 4 CPUs from the mid-1 GHz vary all the way in which as much as 10 GHz by 2005, however the structure was simply barely in a position to hit 4 GHz earlier than warmth and energy consumption each turned so excessive that additional will increase turned untenable (the corporate’s first try at a 4 GHz CPU by no means noticed the sunshine of day).
