AMD Ryzen 7 9850X3D Delidded: Thermal Grizzly’s $876 Overclocking Beast

Thermal Grizzly, known for its high-performance thermal interface materials, is now offering a delidded version of the AMD Ryzen 7 9850X3D processor for $876. This makes it one of the most expensive processors in the Ryzen 9000X3D lineup. The 9850X3D is currently AMD’s flagship gaming processor, succeeding the 9800X3D.

The Ryzen 7 9850X3D features 8 Zen 5 cores, 16 threads, and 96MB of 3D V-Cache. It builds upon the foundation of the 9800X3D, offering a slight performance increase while maintaining the same core architecture and L3 cache size. However, the key difference with Thermal Grizzly’s offering is the removal of the integrated heat spreader (IHS) – a process known as “delidding” – and the intention for use with aggressive overclocking and direct-die cooling solutions.

Delidding involves removing the metal cap that sits atop the processor die. This allows for a more direct thermal interface between the die and the cooling solution, potentially reducing temperatures and improving overclocking headroom. However, the process typically voids the manufacturer’s warranty. Recognizing this, Thermal Grizzly provides a two-year warranty on its delidded CPUs, a significant benefit for enthusiasts willing to take the risk.

The price point of $876 represents a substantial premium over the Ryzen 7 9850X3D’s MSRP of around $526, adding approximately $350 to the cost. Previously, Thermal Grizzly offered a delidded Ryzen 7 9800X3D for around €679 (approximately $712 at current exchange rates). The Ryzen 9 9950X3D is available for a significantly higher $1,168.

What Does a “Delidded” Ryzen 7 9850X3D Mean?

The Ryzen 7 9850X3D is AMD’s most powerful 8-core Zen 5 processor with 3D V-Cache. The delidding process removes the IHS, allowing for direct contact between the cooling solution and the processor’s chiplets. This reduces the thermal resistance between the silicon and the cooler, improving heat transfer.

What are the implications of this modification? Primarily, it enhances the processor’s response to overclocking, where the chip is pushed beyond its standard specifications. By minimizing the thermal barrier, the delidded CPU can maintain lower temperatures under load, allowing for higher clock speeds and improved stability. Thermal Grizzly thoroughly tests each delidded processor, providing a test protocol screenshot on a USB drive included with the CPU, as well as a microscopic image of the delidded die.

Thermal Grizzly recommends using Conductonaut Extreme liquid metal thermal interface material in conjunction with their direct-die cooling solutions (Mycro Direct-Die, Mycro Direct-Die Pro, High Performance Heatspreader) for optimal thermal performance. They also advise protecting the exposed electronic components on the CPU package with a TG Kapton Insulation Sheet or TG Shield when using liquid metal.

Is a Delidded Processor Worth It?

The delidded version is not intended for the average user. It requires a strong understanding of processor operation, including overclocking principles and performance metrics. It necessitates a high-end cooling solution, such as a 360mm or 420mm liquid cooler. The primary goal is to achieve record-breaking clock speeds or maximize benchmark scores.

For typical gamers or everyday users, a standard Ryzen 7 9850X3D or even a 9800X3D is more than sufficient. Gaming performance is often more limited by the graphics card than the CPU, especially at resolutions above 1080p. The $350+ premium for the delidded version is difficult to justify for those solely focused on gaming. This product is geared towards experienced overclockers and enthusiasts who are willing to invest in the hardware and expertise required to unlock the processor’s full potential.

The warranty provided by Thermal Grizzly is a key differentiator, mitigating the risk associated with delidding. However, the warranty is contingent on not re-installing the original IHS, as doing so would invalidate the modifications and the warranty itself.
