You probably can’t hit max clock speeds on AMD Ryzen 9 7950X

As we get closer and closer to the launch of AMD Ryzen 7000, we learn more about the flagship Ryzen 9 7950X. Equipped with an impressive array of specs, the CPU will undoubtedly become one of the best AMD processors on the market.

However, we just learned of a little-known fact about the new Zen 4 CPU: the maximum clock speed is dependent on temperatures, and the threshold is set so low that most people can’t reach it.

The Ryzen 9 7950X comes with 16 cores and 32 threads. The CPU has a huge combined cache of 80MB, of which 64MB comes from L3 and 16MB from L2. The TDP is a maximum of 170 watts.

As far as clock speeds go, Wccftech has discovered something new that we’ve never heard of. As a quick refresher, the Ryzen 9 7950X has a remarkably high base clock speed (4.5GHz), followed by a maximum all-core boost of 5.1GHz. The single core boost, on the other hand, can go up to 5.7 GHz. And then there’s the F-Max frequency, which can reach 5.85 GHz.

Both the maximum peak frequency and the F-Max frequency apply to a single core in stock. However, if you want to push your new Ryzen CPU to 5.85GHz, you’ll need to keep the temperatures at bay. Some of the best CPU coolers are required here, and we don’t mean just any air cooler – it takes a thick liquid AIO kit to keep this beast cool.

According to Wccftech, AMD has internally announced that the Ryzen 9 7950X will only reach maximum clock speed if the CPU temperature is kept below 50 degrees Celsius. Anything above that will lock the processor at the maximum boost speed of 5.7GHz.

While it hasn’t been made clear whether this is a rule or an expectation, the same seems to be true for the all-core boost. If the temperatures get too high, the CPU may instead run below 5.1 GHz and closer to 4.9 GHz to 5.0 GHz instead.

We are not even two weeks away from the big day. On September 27, AMD Ryzen 7000 will officially debut and the processors will be available to anyone who wants to buy them. Coincidentally, Intel will also announce its Raptor Lake processors that same day.
