AMD’s Ryzen 9 7950X has been the subject of a new leak about the clock speeds the next-gen flagship CPU is supposedly capable of.
So, seasoning ready – and a lot – but the statement comes from Wccftech (opens in new tab)whose sources calculate that while we know the 7950X is rated by AMD with a boost of (up to) 5.7 GHz, the peak boost will exceed that, potentially hitting 5.85 GHz as its peak speed (fMax).
What that means is that you might see stock 5.85GHz speeds – which means straight out of the box, with no tuning or overclocking applied – from the main chip, at least sometimes (with a few big caveats, which we’ll dive into one moment).
Apparently, the Ryzen 9 7950X will also have a 5.1GHz all-core boost (a few caveats here, which we’ll again discuss momentarily), meaning the CPU will be able to reach that speed on each of its 16 cores, while the faster mentioned increases will only apply to a single core in many scenarios. Obviously, pushing all the cores out is a much more demanding task than just one or two with the pedal to the metal.
Note that we’ve seen leaks of a top speed of 5.85GHz for a pre-release 7950X in the past, so this confirms the current claim (although this is all still rumor). However, AMD Ryzen processors are known to be able to outperform the nominal increase even on stock configurations, so it’s no surprise to see a modest increase here.
Review: Cooling is paramount with the flagship Zen 4
Keep in mind that usually the nominal 5.7GHz boost is what you’ll get from the Zen 4’s main CPU running in stock – AMD puts that in the box for good reason, of course. However, that 5.85GHz peak frequency is what you might see achieved on a single core occasionally, probably only briefly.
How often this happens will depend on a few main factors, namely how good the processor you bought is – some run a little faster than others, which is known as the silicon lottery, with slight variations in tolerance for being pressed a little more – and there’s also the cooling solution to consider.
Skeptical hat, but Wccftech tells us that, in fact, those 5.85GHz maximums will only be reached when the main CPU temperature is kept below 50C (in other words, when out of any thermal danger, by the sound of things). ). The claim, therefore, is that most users won’t see this peak frequency, at least not straight out of the box, and you’ll likely need a seriously beefy cooler (think liquid cooling) to witness (and even then, as mentioned, will be brief spikes).
Likewise, with the all-core boost to 5.1GHz, some 7950X chips are likely to run a little more conservatively and maybe hit around 5GHz, maybe just a little lower. While variations in that degree don’t have a big impact on overall performance in general.
Don’t forget that Intel’s flagship Raptor Lake is rumored to hit 5.8GHz, so the battle between the Core i9-13900K and the Ryzen 9 7950X is likely to be closely fought – although, naturally, performance depends of much more than just raw clock speeds. What could be crucial for Intel’s side of the equation, in terms of tempting potential buyers, is that Raptor Lake is becoming a good bet for overclockers – the 13900K has already been seen hitting 8GHz with exotic cooling – while there are distinct issues marking it. how much space enthusiasts will have to maneuver with the Ryzen 7000 silicon.
