The timepiece  velocity  wars are backmost  arsenic  Intel brags astir  hitting 6 GHz with 13th-gen CPUs

Intel is gearing up to merchandise the archetypal products successful its 13th-generation Core processor family, codenamed Raptor Lake. Among the topline facts that the institution announced astatine its Intel Technology Tour is that astatine slightest 1 subordinate of the Raptor Lake household volition beryllium susceptible of hitting 6 GHz retired of the container (via Tom's Hardware). Core counts and architectural improvements are mostly much important than timepiece velocity erstwhile it comes to expanding a CPU's show these days, but aft galore years hanging retired successful the 5 GHz range, it's neat to deed the adjacent digit.

As for what this means for performance, Intel is saying that Raptor Lake volition execute astir 15 percent amended successful single-threaded tasks and 41 percent amended successful multi-threaded workloads than the existent 12th-generation Alder Lake chips. Clock velocity is much important for boosting single-threaded performance, portion adding much cores is usually the champion mode to amended multi-threaded speeds.

It's not wide which of the CPUs volition beryllium susceptible of hitting 6 GHz oregon nether what circumstances oregon for however long. An Intel SKU illustration published by Igor's Lab suggests that the Core i9-13900K volition apical retired astatine 5.8 GHz, though it's imaginable that it's susceptible of further boosting beyond that.

A purported SKU illustration  for the 13th-gen chips doesn't notation  the 6 GHz limit, but boosting works   successful  mysterious ways.

The SKU illustration besides confirms what we've heard from different leaks—despite an architectural similarity to existent Alder Lake CPUs, Intel is boosting show by doubling the maximum fig of E-cores successful its top-tier CPUs, from 8 to 16. The i5-12600K, which included 4 E-cores, volition besides beryllium replaced by a Core i5-13600K that includes eight. And if the remainder of that leaked desktop CPU lineup holds true, immoderate lower-end Core i5 processors that shipped with no E-cores successful the 12th procreation volition get 4 oregon 8 successful the 13th generation.

This SKU illustration besides indicates that these top-end Raptor Lake CPUs volition see different changes, including accrued amounts of L2 and L3 cache available. It besides looks similar the Maximum Turbo Power depletion of each the chips is going up by betwixt 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 basal powerfulness for each the chips stays level, astatine 125 W.

Those maximum powerfulness depletion numbers don't needfully mean that each Raptor Lake CPUs volition devour much powerfulness than their Alder Lake counterparts—that volition beryllium connected the circumstantial powerfulness settings that your motherboard oregon PC shaper chooses to use. It does mean that a Raptor Lake CPU with precocious powerfulness limits and capable cooling volition request much powerfulness and amended cooling than a likewise configured Alder Lake CPU erstwhile moving sustained workloads, though.

People aged capable to retrieve installing Windows 98 volition callback that timepiece velocity bragging rights were a large woody successful the aboriginal 2000s. Intel planned to boost its Pentium 4 CPUs from the mid-1 GHz scope all the mode up to 10 GHz by 2005, but the architecture was conscionable hardly capable to deed 4 GHz earlier vigor and powerfulness depletion some became truthful precocious that further increases became untenable (the company's first effort astatine a 4 GHz CPU ne'er saw the airy of day).
