New reports on the thermal performance of AMD Ryzen 7000 CPU have been shared by Enthusiastic citizen in Bilibili And it looks like the upcoming Zen 4 chips will require some serious cooling hardware to keep them tamed.
AMD Ryzen 7000 CPUs Run Great With Ryzen 9 7950X Going Up To 95C At 230W And Ryzen 5 7600X Going Up To 90C At 120W, Rumor Alleges
The leaker who has been very reliable with his past information and leaks has stated that AMD’s Ryzen 7000 desktop CPUs based on the Zen 4 core architecture will be some of the best chips produced to date. The leaker talks about two specific chips, an AMD Ryzen 9 7950X and the Ryzen 5 7600X. Please note that information shared is based on ES/QS samples, so final results may vary.
So getting to the nitty-gritty, the AMD Ryzen 9 7950X is reported to throttle below 5.0GHz on intensive tasks as it comes with a thermal threshold of 95C or TjMax and will need some beefy coolers to keep the chip running under that. . At full load on stock settings, the CPU is said to consume up to 230 watts of power and run up to 95C. The Ryzen 5 7600X is also a similar scenario, with the chip drawing up to 120W of power at full load and reaching temperatures of up to 90°C.
This time Zen4 vs. RPL, the multicore 7950X will lose to the 13900K with no suspense. The accumulated heat combined with the temperature wall will make the 7950X under heavy load unable to sustain 5G, 230W at 95 degrees, and will turn to ash when powered off. Even the R5 isn’t much better, 120W 90 degrees, which is a compromise in cost. 230 W 95 degrees Zen4 vs. 270 W 82 degrees RPL,
I have to say it’s nice to have money, and shit can be done casually. In terms of price, AMD may not have any advantage this time. The first X670E is not cheap. DDR5 is still not as cheap as DDR4. Although the AMD CPU may be cheaper, Intel will have cheaper B660 and DDR4 at this stage. R5 users remain honest. just wait All data is from ES/QS, accuracy is not guaranteed.
We have also heard reports from our sources that the AMD Ryzen 9 7000 series chips run at 92-94C with a high-end 360mm AIO liquid cooler in AIDA64. No overclock was applied and once again this is the result of a standard QS chip. The leaker went on to compare the thermal density and performance of AMD’s Ryzen 7000 CPUs to Intel’s upcoming 13th Gen Raptor Lake CPUs.
He reports that despite drawing a much higher wattage of 270W, the Raptor Lake CPU can maintain temperatures much lower than 82°C at full load using the same cooling equipment as the Ryzen CPUs. He even goes on to show an overclocking result of the 5.3 GHz all-core Intel Core i9-13900K that can withstand temperatures below 85C.
Considering the Zen 4 chipsets are smaller than their predecessor but much denser, they will require a lot of cooling. It sounds like that might be one of the reasons why the chiplets are also gold plated this time around to effectively draw as much of the heat away from them towards the IHS. While 170W is the maximum TDP rating of the CPU, its PPT or Peak Packet Power is rated at 230W and a figure of 280W is used for OC. The figures also include the IO die, which should be around 20-25W on its own. The following is a breakdown of thermal density by Harukaze5719:
All of this means that users should definitely expect to invest in some really high-end AIO coolers if they plan to build a new PC with AMD’s Ryzen 7000 desktop CPUs. Of course, this is just a rumor for now and we will wait for the final tests and reviews to confirm the validity of this rumor, but AMD has gone to great lengths to make sure that the heat is dissipated from the CPUs for casting a gold plating on the IHS and Zen 4 CCDs as detailed here. AMD Ryzen 7000 CPUs launch alongside the AM5 platform on September 27.
