AMD’s Robert Hallock confirms Ryzen 7 5800X3D does not support overclocking. The Director of Technical Marketing at AMD has revealed in an interview that the first Ryzen CPU with 3D V-Cache will not support traditional overclocking.
The CPU will not permit overclocking which implies that customers will not be able to adjust the frequency or the voltage. However, by a standard definition the CPU won’t support overclocking but it will be possible to adjust Infinity Fabric and DRAM clocks that will improve performance.
Hallock further explained that the CPU voltage does not go beyond 1.35V. This field still needs to be worked on. As we know, the 5800X3D is the first part with the large L3 cache placed on top of the 8-core chiplet. It has not been optimized for overclocking. AMD decided not to wait and launch the first 3D V-Cache part for gamers to try, even though it has not been prepared for overclockers.
The Ryzen 7 5800X3D has a base clock of 3.4 GHz and a boost of 4.5 GHz. This implies that this model is 400 and 200 MHz slower than the original Ryzen 7 5800X respectively. However, the company claims that it will give 15% better performance on average than Ryzen 9 5900X due to the 3D V-Cache.
5800X3D being unsupportive of overclocking does not rule out AMD’s intent to disable this feature for future CPUs. It is expected that if AMD overcomes the scaling problem, the overclocking will be facilitated for other SKUs with similar types of cache.
AMD Ryzen 7 5800X3D is expected to launch on April 20th with a price tag of 449 USD. Intel Core i9-12900KS will be its competition which is expected to launch by the end of March.
