AMD has announced the Ryzen 7000 X3D series, which will release at the end of February with the exception of the 7800X3D, which will release at the start of April. The Ryzen 7 7800X3D happens to be the focal point of our article today, as we are asking: Can you overclock the Ryzen 7 7800X3D?
Now Read: AMD Ryzen 7 7800X3D Vs 5800X3D
The reason we’re asking whether or not you can overclock the Ryzen 7 7800X3D is because of the previous generation. The Ryzen 7 5800X3D was a fantastic CPU in many ways, but also limited in many. The 3D V-cache inside the Ryzen 7 5800X3D was extremely sensitive to high temperature and voltage. Because of this, the 5800X3D was locked to all overclocking and just ran at the base speeds.
This limitation severely impacted the 5800X3D’s ability to compete with other processors outside of gaming workloads. Making the 5800X3D only good for one thing.
To kick things off, let’s take a look at the 7800X3D’s specifications.
Ryzen 7 7800X3D specs
- Architecture: Zen 4
- Core count: 8
- Thread count: 16
- Boost speed: 5.0GHz
- Cache: 104MB
- TDP 120W
The Ryzen 7 7800X3D probably going to be one of the most efficient X3D CPUs on the market, offering the best price-to-performance ratio. This time around, the X3D release includes a trio of processors, meaning the 7800X3D is not going to be the best performer. However, we still can’t wait to see what it’s capable of.
What’s the main difference between the 7800X3D and the 7800X?
The two CPUs are different due to the addition of a large amount of AMD’s 3D V-cache. The latest 3D V-cache, stacked vertically on a single CCD, offers space-saving advantages on the CPU die without compromising speed.
The extra cache allows the CPU to hold more data, reducing its reliance on slower system memory. This leads to enhanced single-core gaming performance and optimized multi-core performance, due to the preservation of clock speeds on the other CCD. This design choice balances the advantages of the 3D V-cache, unlike the 5800X3D which experienced decreases in both clock speed and overclocking ability.
Can you overclock the Ryzen 7 7800X3D?
Unfortunately, you cannot manually overclock the Ryzen 7 7800X3D. However, there is still some overclocking capability present here.
The Ryzen 7 7800X3D, along with the other Ryzen 7000 X3D processors, will feature PBO and Curve optimizer support. This means that there is some overclocking to be had here, even if it is automatic overclocking. With that being said, PBO is very efficient nowadays and we’re sure it’ll make a big difference over base speeds.
Why does 3D V-cache restrict CPU overclocking on the 7800X3D?
The 3D V-Cache is vulnerable to high voltages and temperatures generated by boosting the core frequency. To guard against overheating and voltage surges, the 7800X3D has been limited to a voltage of 1.4V and a TDP of 120W.
If left unchecked, these spikes could lead to instability or damage to the cache, rendering the CPU ineffective. However, AMD has advanced the technology by incorporating conventional PBO, EXPO, and Curve optimizer support into the chip.
