As part of an interview with HotHardware , AMD CMO Robert Hallock confirmed that the Ryzen 7 5800X3D processor with 3D V-Cache technology does not have manual overclocking support in the usual sense.
Processor owners will not be able to increase the frequency of the processor or change its operating voltage. However, the performance of the chip can be improved by changing the frequency of the Infinity Fabric bus and overclocking the RAM. Hallock also noted that unlike the rest of the Ryzen 5000 processors, the operating voltage of the Ryzen 7 5800X3D processor does not exceed 1.35 V.
By itself, the Ryzen 7 5800X3D is more of an experiment. This is AMD’s first consumer chip to use an additional 64MB SRAM layer on top of the 8-core processor chiplet in addition to the usual 32MB L3 cache. At the moment, the technology is not fully optimized, so support for manual overclocking is not provided.
The company positions this processor primarily for games. This is where the extra 3D V-Cache should have the most positive impact. Recall that the base frequency of the Ryzen 7 5800X3D is 3.4 GHz. Under load, it can increase up to 4.5 GHz. This is 400 and 200 MHz lower 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 on average up to 15% faster 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 opportunity for its processors in the future. The company believes that 3D V-Cache technology needs to mature. As soon as the manufacturer resolves all related issues, 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 of the processor is $449. The novelty will directly compete with the Intel Core i9-12900KS, which is expected to start selling by the end of this month.
