I'm building a mid-range gaming and video-editing PC with a Radeon RX 9060 XT and an MSI B850M Gaming WiFi6 MicroATX AM5 motherboard. Before DDR5 prices increased, I bought a 2x16GB kit rated for 6400 MT/s. The Ryzen 7 7700 and Ryzen 5 9600X are available for nearly the same price where I live. From the comparisons I've seen, the 9600X is slightly better for gaming because of its newer architecture and stronger single-core performance, while the 7700's 8 cores and 16 threads make it better for productivity and editing. How important is the advertised boost-clock difference—5.3 GHz for the 7700 versus 5.4 GHz for the 9600X—and would either CPU be a poor choice with my 6400 MT/s memory? I'm particularly concerned about having to lower the RAM speed and whether running it at higher speeds could reduce its long-term lifespan.

At similar prices, I’d lean toward the Ryzen 7 7700. The two CPUs are close in gaming, with the 9600X sometimes ahead thanks to Zen 5’s IPC improvements, but the 7700’s extra two cores can help with video editing, multitasking, and games that make better use of more threads. The small boost-clock difference shouldn’t be a deciding factor.
The Ryzen 7 7700 is also a good choice if power efficiency matters. Its 65W rating keeps temperatures and power consumption modest, while still providing 8 cores and 16 threads. The 9600X is attractive for a gaming-first build, but with editing included and both CPUs priced similarly, the 7700 offers the more versatile package.
You aren’t making a mistake by using the RAM you already bought. Just enable the memory profile and test stability; if 6400 MT/s causes errors or won’t run properly, set it to 6000 or 6200 MT/s. The performance difference will be small, and using a lower stable speed is preferable to forcing high voltages. Normal memory overclocking at reasonable settings should not create a meaningful wear concern.
The memory specifications listed by AMD are conservative official support numbers, not hard limits. Both processors should generally handle DDR5-6000 easily, and DDR5-6400 may work with manual tuning, but it isn’t guaranteed on every CPU or memory kit. For AM5, DDR5-6000 with the memory controller running 1:1 is usually the sensible balance of speed, latency, stability, and ease of setup.
