AMD Ryzen 7000 X3D CPUs Have A 6C Lower Tjmax of 89C Versus The 95C On Non-3D V-Cache SKUs

0 1

AMD has chosen to play it safe with the TjMax of its forthcoming Ryzen 7000 X3D central processing units (CPUs), which use Zen 4 cores and layered 3D V-Cache.

The AMD Ryzen 7000 X3D TjMax Can Be Configured At 89 degrees Celsius, Who Is 6 degrees Lower Than Other CPUs Without 3D V-Cache.

Andreas Schilling of Hardwareluxx discovered that AMD appears to have revised the maximum temperature restriction, also known as TjMax, for the forthcoming Ryzen 7000 X3D central processing units (CPUs).

AMD has assured customers they have nothing to worry about because this operation is within spec, and the current Zen 4 range is listed to have a TjMax of 95C. Even though the CPUs can quickly reach that target, AMD has reassured consumers they do not need to. These high-temperature limitations appear to be the standard for AMD since their GPUs also have a peak temperature limit of up to 110 degrees Celsius, referred to as the “Normal Spec.”

The TjMax for AMD’s Ryzen 7000 X3D central processing units (CPUs), which include the Ryzen 9 7950X3D, Ryzen 9 7900X3D, and the Ryzen 7 7700X3D, is now listed on the company’s product pages as 89 degrees Celsius. This is 6 degrees Celsius less than the TjMax for Ryzen 7000 Non-3D CPUs, which is 95 degrees Celsius. There is a sound rationale behind AMD’s decision to set a lower temperature limit for its 3D V-Cache chips; this is the same rationale behind the decision to disable the ability to overclock these components manually.

  • Ryzen 9 7950X3D CPU TjMAX – 89C
  • Ryzen 9 7950X CPU TjMAX – 95C
  • Ryzen 7 5800X3D CPU TjMAX – 90C
  • Ryzen 7 5800X CPU TjMAX – 90C
AMD Ryzen 7000 X3D CPUs Have A 6C Lower Tjmax of 89C Versus The 95C On Non 3D V Cache SKUs

According to what we learned the day before yesterday, AMD has the maximum voltage of the Ryzen 7000 X3D CPUs set at 1.4V. This is an increase of 0.3V in comparison to the Ryzen 7 5800X3D. (1.1V). The new CPUs will come with auto OC options such as PBO and Curve Optimizer, but manual overclocking is restricted because of the volatile nature of the 3D V-Cache stacked on top of the singular CCD. The new CPUs will come with auto OC options such as PBO and Curve Optimizer. Both high voltages and high temperatures might cause the chip to behave abnormally and possibly cause it to get damaged.

The hybrid layout of the dual CCD SKUs, such as the Ryzen 9 7950X3D and the Ryzen 9 7900X3D, is already being optimized in the Windows 11 operating system; however, it is unknown how high temperatures will impact the clock operation of these components. Specifically, the Ryzen 9 7950X3D and the Ryzen 9 7900X3D.

To keep the temperature below 89 degrees Celsius, you will need some high-end cooling systems. This may also explain why AMD decided to go with a lower 120W TDP on the higher-end SKUs; to prevent them from drawing excessive power and hitting a thermal wall, AMD likely made this decision. We can’t wait for AMD to continue delving further into the next edition of their 3D V-Cache processors because the next few weeks will be pretty exciting.
