AMD Ryzen 7000 and Intel Core i 13 Gen at almost 6 GHz clock speed

Posted by Stefan on 2022-08-29, Last updated:
In September, both AMD and Intel are introducing their new mainstream desktop processors. It doesn't seem to have been as close as this year for a long time, leaked benchmarks of the new top models from AMD and Intel point to a head-to-head race.

This year even the 6 GHz clock limit is almost within reach. With a good cooler and some overclocking it should be possible to reach the 6 GHz limit. But even in series production, the manufacturers try to enable the highest possible clock frequency, at least on one core.

Release date of AMD Ryzen 7000 and Intel Core i 13th Gen

While AMD will present the Ryzen 7000 processors on August 29th (availability on September 15th), the September 27th (release October 17th) is rumored as release date for the newest Intel processors. Apple will most likely expand its M2 processor in the fall (October?) with more powerful models in the form of the Apple M2 Pro and Apple M2 Max.

AMD Precision Boost 2 vs Intel Thermal Verlocity Boost

Also this year the new Intel Core i9 processors will again be supported with the Intel Thermal Velocity Boost. This can increase the maximum clock frequency of the processor by up to 100 MHz (0.1 GHz) if the processor temperature is below 158 °F (70°C).

The AMD Precision Boost 2 works similarly, but is marketed differently by AMD than Intel. AMD speaks of a slight overclocking, which is also not guaranteed. If the processor becomes unstable under PBO, there is no good reason to return the processor.

The AMD PBO 2 is also not constantly active, but only when this function is activated in the mainboard's BIOS. In addition, the usage of the PBO 2 also depends on the processor temperature, the type of workload and the number of active CPU cores.

CPU architecture and core structure

While Intel in the 13th generation of the Intel Core i series (Raptor Lake) is again based on the big.LITTLE structure known from Alder Lake, consisting of powerful P-cores and energy-saving E cores, AMD uses CPU cores of the same size. Rumors are that AMD will also switch to a hybrid core structure with the Ryzen 8000 series in 2023.

Competitive pressure is increasing

The increasing competitive pressure is increasing more and more. This forces the manufacturers to let the improvements in manufacturing technology flow fully into the performance, at least in the desktop area. The most recent improvements hardly benefit energy consumption. This can also be seen in the Apple M2 processor presented in June 2022. Although this has a higher performance than the Apple M1, the energy consumption is even higher than its predecessor.

Power consumption of new CPUs not important ?

When it comes to desktop processors, AMD has so far been ahead of the game when it comes to energy consumption. Intel had been bogged down in outdated manufacturing processors for too long, while AMD was able to use the modern TSMC manufacturing in 7nm. Nevertheless, Intel had managed not to fall too far behind in terms of performance in recent years and was even able to overtake AMD with the 12th generation of the Intel Core i series "Alder Lake" thanks to a hybrid structure.

Nevertheless, the current Intel processors consume a good amount of energy. Now it seems as if AMD is also forced to look less at energy consumption and more at performance with the current Ryzen 7000 desktop processors. With the AM5 socket introduced this year, this seems possible: instead of 105 watts (AMD Ryzen 9 5950X), the new top model, the AMD Ryzen 9 7950X, now comes with a TDP of 170 watts. In the short term, the new top model can even consume up to 230 watts. The maximum energy consumption of the AMD Ryzen 9 5950X was 142 watts.

Intel's top model for this year is the Intel Core i9-13900K. Its TDP is 125 watts, but this hardly plays a role. In reality, the CPUs consume significantly more energy as long as the processor's temperature allows it. The short-term power consumption (PL2) of the Intel Core i9-13900K is like its predecessor at 241 watts and thus only slightly above the maximum of the AMD Ryzen 9 7950X.

Intel had already demonstrated last year with the release of the Intel Core i9-12900KS that the LGA1700 socket can even accommodate processors with a TDP of up to 150 watts (241 watts PL2).
