An anonymous overclocker has had the opportunity to reveal the next CPU AMD Zen4 and with it has published an image of the new integrated heat sink. But it is seen that this Ryzen 7000 heatsink could cause overheating problems.
The biggest problem with this integrated heat sink (IHS), and the factor that will decide the thermal performance of these CPUs, is its thickness, which is too thick for an IHS. In the published image you can see the I/O die and the two chiplets, which although they are all attached to the IHS with a gold foil that has a problem due to its thickness. The important thing to know is that more material, regardless of its material, Provides greater thermal resistance in the transfer of heat from the chips to the heat sink or block. A difference of 1 mm can cause a difference of 3 to 4 degrees in temperature.
A leaked AMD Ryzen 7000 could have too much material on its heatsink
As has been seen, the thickness of the lid of this Ryzen 7000 series processor could cause overheating problems in a general way. Another important factor could be the distance between the dies. The distance between the dies of the processors has been reduced to just 1 millimeter. It can give much higher performance than before. but being so close, it will concentrate the heat dissipation zone and could increase temperatures of the CPU.
It's also possible that this is an engineering sample, and that AMD is making changes for release. But if it stays in the final product, the Ryzen 7000 is going to have widespread problems keeping temperatures under control. Add to that its 230W power consumption along with 5,85MHz processor frequency, and this overheating issue could be compounded and become widespread.
AMD Ryzen 7000 series processors will be released at the end of September and they have been codenamed “Raphael”. There are many expectations about them, since they will offer PCie 5.0 and DDR5 for the first time on the AMD platform, two elements that Intel has been offering for half a year now with its Alder Lake. A general problem of overheating, which will imply a higher energy cost in cooling to get the most out of it, or that these frequencies are hardly achievable if you do not have a great cooling.
