AMD: the Ryzen 9 7950X would reach 5.85 GHz in stock… only if its temperature is below 50°, why?
Expected in September, the processor monster that promises to be the AMD Ryzen 9 7950X shows off its power.
To take full advantage of it, however, it will be necessary to keep the infernal beast below 50 degrees… a task that promises to be complicated.
A powerful flea with an ogre appetite
At its peak of stock power, the Ryzen 9 7950X intends to deliver a frequency of 5.85 GHz F-Max. In boost, however, the processor should be “limited” to 5.70 GHz in single-core performance. The tests carried out internally by AMD indeed indicate that the frequency peak at 5.85 GHz for a single core can only be maintained if the beast remains below 50 degrees.
Knowing the unfortunate tendency of AMD processors to heat up like a forge, such values will require reinforced concrete cooling… or a cold room. Knowing that the maximum limit supported by the processor amounts to nothing less than 95 degrees. Unless you have an extremely well-equipped AIO kit or a well-hung cooling system, the overwhelming majority of PCs will therefore only be able to benefit from a boost amounting to 5.70 GHz.
AMD has thus detailed the performance expected by the clock of the Ryzen 9 7950X, which is as follows:
Base clock: 4.50 GHz (stock);
Clock boost: 5.70 GHz (stock);
Clock peak: 5.85 GHz (stock);
All-Core Boost: 5.10 GHz (stock).
Values that make you dizzy
The peak of the clock at 5.85 GHz is only interested in one core. If the 16 cores (for 32 threads) that make up the processor are boosted, the clock will therefore stop at 5.10 GHz. But again, temperature will play a crucial role in these values. Configurations that do not have a sufficiently efficient cooling system therefore risk seeing the all-core boost lose its luster slightly.
In addition to this enticing count of hearts and frequencies that make you want, the Ryzen 9 7950X looks particularly well equipped. It will indeed be able to count on 80 MB of cache distributed according to 64 MB on the L3 and 16 MB on the L2 (i.e. one MB per core).
AMD thus seems to have done its best to make the most of a TDP of 170W (or 230W PPT). To take advantage of the future flagship of Team Rouge expected later this month (if you have a thunder cooling system), it will however cost 700 euros excluding taxes.
