AMD announced its Ryzen 7000 CPUs along with the new AM5 socket a few days past. Long story short, Intel’s Alder Lake is in trouble both performance wise and efficiency wise. These CPUs boast extreme performance metrics thanks to the new 5nm process node and a complete architectural redesign. However, recent reports suggest that these big numbers come at a cost.
A Rather Hot CPU
Enthusiast Citizen over at Bilibili suggests that AMD’s Ryzen 9 7950X will lose to Intel’s upcoming 13900K in multi-core testing. The tests featured ES/QS chips, so the results may differ by a bit.
Ryzen 9 7950X
As reported, the flagship R9 7950X will generate so much heat that the CPU will not be able to maintain 5.0GHz at 230W as the temperatures reach 95C. This effectively means that Zen4 is heat bottlenecked.
AMD’s 50% less area as compared to Intel leads to higher thermals as heat is dissipated better with a larger surface area. In addition to that, the 230W power limit pushes the chips to its maximum limits.
Ryzen 5 7600X
Moving on to the budget-friendly R5 7600X, the thermals go as high as 90C at 120W. That’s actually quite a lot for a budget chip. Besides, high-end cooling solutions costing a fortune will often not be utilized.
The Elephant In the Room
In comparison to this, a picture provided by Wccftech shows the Raptor Lake based i7-13700K runs at 80C while consuming around the same amount of power (224W). Similarly, as per Wccftech’s sources, the Ryzen 7000 CPUs run at 92–94C even after being paired with a 360mm AIO Liquid cooler in AIDA64.
From the source itself, a 270W Raptor Lake CPU (possibly the i9-13900K) maintains thermals of around 82C as compared to the 230W R9 7950X which runs at 95C. What happens next? Well, AMD may possibly lose in multi-core testing and even single-core if these numbers prove to be true when Zen4 retails.
Enthusiasts may give the crown to AMD on using an extremely high end exotic cooling solution, but average consumers may not see the same results.
Harukaze gave us the Wattage/Unit Area of the Raptor Lake and Zen4 CPUs. The numbers speak for themselves. The Raptor Lake CPUs have less heat generated (The unit used is Watts, but it directly relates to the heat produced as a byproduct).
What Does this Mean For Us?
Basically, if you are looking to buy a Ryzen 7000 CPU, make sure to invest in a good cooling solution, like a PC case with adequate airflow and some high-performance fans. Besides, you will need DDR5 memory along with a new motherboard. The Ryzen 7000 CPUs are set to hit the shelves by the 27th of September. Are you excited for Zen4?
