Best AMD CPU For RX 7800 XT
Socket: AMD AM5 | Cores: 8 | Threads: 16 | L2 Cache: 8MB | Base Clock: 4.2 GHz | Boost Clock: Up to 5.0 GHz | TDP: 120W | Unlocked: No
Pros
- 3D V-Cache design
- Extraordinary gaming performance
- Solid productivity performance
- Reasonable power draw
Cons
- Locked multiplier
- Expensive
Performance: AMD’s implementation of the 3D V-Cache technology has propelled the Red Team to the top of gaming performance charts for a while now, and the Ryzen 7 7800X3D is no different. Based on the new Zen 4 architecture, the Ryzen 7 7800X3D is packed with 8 cores and 16 threads, with a boost clock of up to 5.0 GHz. Coupled with the excessive amounts of L3 cache, the sky-high boost clock allows the Ryzen 7 7800X3D to deliver outstanding single-threaded performance when paired with the Radeon RX 7800 XT.
Cooling: With a reasonable TDP rating of 120W, AMD has positioned the Ryzen 7 7800X3D as a mid-range performer in terms of temperatures and power draw. During the course of my testing, my sample of the Ryzen 7 7800X3D peaked at around 84C during an all-core stress test while being cooled by a Noctua NH-U12S. While gaming, the cores are engaged in a variable manner, and the temperatures leveled out at around 68C. A high-quality tower cooler or a 240mm AiO liquid cooler should be the cooler of choice to be paired with this CPU, if not better.
Overclocking Potential: AMD’s X3D processors do not typically have an unlocked multiplier for overclocking, and the same holds true for the AMD Ryzen 7 7800X3D. Although the new Ryzen 7000X3D processors are better than their predecessors in their flexibility, the multiplier is still locked. You can, however, practice overclocking using Precision Boost Overdrive (PBO) and Curve Optimizer (CO). Just be advised that the results may not be all that glamorous, and you may need a hefty aftermarket cooler to stabilize the temperatures.
