Intel’s stock Raptor Lake hits 6GHz, will overclock to 8GHz • The Register

Intel says its 13th Gen Raptor Lake CPUs will serve 6 GHz in the standard configuration and 8 GHz higher when overclocked, according to slides shared during the company’s Tech Tour in Israel this week.

This would give Intel a clock rate advantage (300 MHz) over AMD’s Ryzen 7000 series CPUs, announced late last month, which top out at 5.7 GHz. it is just a measure of performance and instructions per clock (IPC) and thermal headroom can play an equally important role in actual performance.

It’s also worth noting that AMD has a habit of under-promising and over-delivering with its Ryzen desktop CPUs. Ryzen 5000 processors routinely delivered clocks 50-150MHz higher than advertised. For example, the Ryzen 9 5900X claimed a single-core boost clock of 4.8GHz, but actually delivered closer to 4.95GHz on stock settings. If the same ends up being true for Ryzen 7000, Intel’s frequency advantage may end up being narrower than it seems.

It is not clear if the 6GHz Reported Claims Will they be in Intel’s main chips or reserved for another flagship part of the KS series, Intel was previously able to get an extra 300 MHz, for a maximum boost clock of 5.5 GHz by bundling its best 12900K CPUs, which were sold as 12900KS.

Since AMD is claiming its entry-level 7600X can outperform Intel’s 12900K, it will be interesting to see how these chips compare in real-world tests.

As for Intel’s claims of a “world record” overclocking of 8 GHz, it’s unclear what measures are required to achieve such a frequency. However, an exotic cooldown is likely. At Intel’s 12th Gen launch event last year, the company attempted to overclock the chips with liquid nitrogen, only for the system to crash. shock half of the live broadcast.

If this type of overclocking is required, few if any can expect to see 8Ghz on any Raptor Lake CPU.

It’s also unclear if achieving these higher clock speeds required additional power over Alder Lake. The latter provided a substantial increase in frequency last year, but Intel paid for it with increased power consumption, especially on the chipmaker’s overclocking-enabled K SKUs.

Increasing the power consumption (TDP) of chips to achieve higher performance has become something of a trend among consumer and data center platforms in recent years.

Intel’s 12900K, for example, is capable of extracting 241W low max turbo But Intel isn’t the only chipmaker pushing higher voltages in exchange for higher frequencies. Nvidia’s 3090 TI made waves when it was Announced earlier this year, not only because of its $1,999 MSRP but because the minimum recommended power supply required an 850W PSU and quoted power consumption of around 450W.

AMD has also increased the TDP of its Ryzen 7000 CPUs to between 40 and 65 W, depending on the SKU. Although during the company’s launch event, AMD went to great lengths to claim that TSMC’s 5nm process was actually more efficient, suggesting that the higher TDPs may not be indicative of the actual power consumption of the chip. under load.

That said, unless Intel has managed to improve the efficiency of its 10nm process or packaging techniques, its K-class desktop chips will almost certainly require liquid cooling to unlock their full potential.

Intel’s Raptor Lake CPUs are expected to launch later this year. ®
