In an interview with the publication hot hardware AMD CMO Robert Hallock has confirmed that the Ryzen 7 5800X3D processor with 3D V-Cache technology does not support manual overclocking in the usual sense.
Processor owners cannot increase the frequency of the processor or change its operating voltage. However, the chip’s performance can be improved by changing the frequency of the Infinity Fabric bus and overclocking the RAM. Hallock also noted that unlike the other Ryzen 5000 processors, the operating voltage of the Ryzen 7 5800X3D processor does not exceed 1.35V.
In itself, the Ryzen 7 5800X3D is more of an experiment. This is AMD’s first consumer chip to use an additional 64MB layer of SRAM on top of the 8-core processor chiplet, in addition to the usual 32MB of L3 cache. At the moment the technology is not fully optimized, so manual overclocking is not supported.
The company positions this processor primarily for gaming. The additional 3D V cache should have the most positive effect here. Remember that the base frequency of the Ryzen 7 5800X3D is 3.4 GHz. It can increase up to 4.5 GHz under load. That’s 400 and 200MHz slower than the original Ryzen 7 5800X. However, the presence of 3D V-Cache significantly increases the performance of the Ryzen 7 5800X3D in games. According to AMD, the new product is up to 15% faster on average than the 12-core Ryzen 9 5900X.
The lack of manual overclocking support for the Ryzen 7 5800X3D does not mean that AMD has decided to change its policy regarding the availability of such an option for its processors in the future. The company believes that 3D V-Cache technology needs to mature. As soon as the manufacturer solves all related problems, overclocking support will appear in future consumer processors that will be released with the same cache technology.
The official release of the Ryzen 7 5800X3D is scheduled for April 20th. The recommended cost for the processor is $449. The novelty will compete directly with the Intel Core i9-12900KS, which is expected to go on sale later this month.
