In a few weeks, the new range of Intel CPUs will be released, and if performance is a concern, it's not the only characteristic that raises questions.

While Intel seems to have finally clarified its plans for the evolution of desktop processors - Rocket Lake-S in March/April and Alder Lake-S for the beginning of September - the company is not off the hook. About Rocket Lake-S - the closest to us - there has already been the controversy around the performance. On the one hand, we have Intel, which presented a graph showing the gains observed on a large handful of video games between the Core i9-11900K and AMD's rival, the Ryzen 9 5900X. On the other hand, we have a Chinese site that pointed out that the Core i9-11900K was especially less speedy than the Core i9-10900K on many games, but with a methodology that raises questions.

Today, it is a very different problem that has been highlighted by the site Chiphell. The latter publishes a screenshot highlighting the "dramatic" heating of a Core i9-11900KF, a processor very close to the Core i9-11900K mentioned earlier. Chiphell mentions a consumption of about 250.83 Watts during a stress test, which puts a lot of strain on the CPU. Of course, a "classic" use will not put as much strain on the chip, but it is still worrying. Even more worrying is that it went hand in hand with a worrying temperature rise. According to Chiphell, the Core i9-11900KF reached 98°C despite using a 360mm AiO. Even on very demanding tests, the Ryzen 9 5900X hardly ever reaches 80°C.

So it could be that the energy efficiency of the new Intel range is not on a par with its most direct competitors. However, this statement needs to be verified with a real and clearly established protocol and comparable test conditions. Let's keep in mind that these first tests, published in China, use BIOSes that will obviously evolve between now and the actual release of the Intel chips.
