| JEMC said: The 9950X has a higher TDP than the 9800X3D, and yet we haven't seen cases of it burning down. I don't think that is one of the causes for all these troubles. Unless Asus has done an AsRock and has launched a messy BIOS, killing those CPUs, we should start asking AMD why so many of their new cache on the bottom X3D processors are dying. Maybe the design can be improved. |
The X3D parts use stacked silicon which concentrates more thermal energy into a smaller surface area for a heatsink.
Think of the vcache as a little heater sitting under the cores... Electrons can also potentially leak between layers as well if the grade and insulation of the chips aren't sufficient.
The 9950X is able to spread it's thermal load over a relatively larger area. Watt for watt.
But there is more to it, the motherboard software with Asrock wasn't actually reading CPUID's properly, so it was treating X3D parts like non-X3D parts for things like precision boost... And that is where the issues start.
...But when you start to dig a little deeper on how these motherboards are designed with the software placed-on top, Asus, Asrock and other board manufacturers aren't actually building their own BIOS solutions from complete scratch.
Rather they are taking a "reference" BIOS (AGESA) and making changes on top of it, so if the "Reference" BIOS has a certain flaw, all motherboard manufacturers have a chance of experiencing that flaw with production models.
So the issue to this likely stems from Asmedia and/or AMD via AGESA (AMD Generic Encapsulated System Architecture).
