You'll see a significant improvement jumping from 3900x to 7600x. The performance gain is substantial, especially with modern games. Not skipping an 8-core CPU won't hurt much, but it won't match the power of a higher core count.
Here’s a revised version of your text:
I’m setting up a custom case with a 420mm air cooler from Arctic Cooling, an NVMe SSD for the boot drive, a 2TB NVMe SSD for Steam, a Seasonic Gold rated PSU 6700X, a GPU supporting 1080p at 144Hz, and a monitor. This configuration supports heavy workloads, gaming, basic browsing, and YouTube watching. If I need to handle demanding tasks, my dual socket LGA 2011 server will suffice. This setup is intended solely for gaming at maximum settings.
For gaming, you'll see only a noticeable boost with a 7600X compared to a 3900X. The 7600X performs significantly faster for gaming, matching the speed of the 5800X3D. In multi-core setups, it remains competitive with the 5800X3D. After a few weeks, the 9600X is expected, possibly gaining another 15-20% in speed. In multi-core scenarios, its performance can approach that of your current CPU overall. Core count reflects clock speed and is most relevant when comparing within the same architecture. A modern 6-core processor can match the efficiency of a 12-core model if its cores are powerful enough.
Based on the benchmarks and reviews I've reviewed, the 7600X would perform competitively, possibly even ahead of a 3900X in many situations. Zen 4 delivers significantly higher clock speeds compared to Zen 2 and offers a substantial 30%+ improvement in IPC along with enhanced memory bandwidth via DDR5. The 7700X matches the 3900X in Cinebench scores, while the 7600X is expected to lag around 20-25% behind. With cooling and clock choices, it could sit between 14,500 and 16,000 depending on those factors. Even a six-core version would provide roughly an extra GHz of core clock time compared to the 3900X. This translates to about a 4GHz difference versus around 5GHz, which is approximately a 25% boost in clock speed per core. Adding the ~30%+ IPC advantage brings performance closer to 50-60% faster per core than the 3900X. This positions a 6-core Zen 4 chip near an 8-core Zen 3. My estimate for the 3900X is around 19,000 in CB23, suggesting the 7600X could be about 15% faster overall. That would mean the 3900X is roughly 22% quicker in a full-core setup. TLDR: The 7600X would generally outperform the 3900X, potentially by half or more in gaming, and the 9600X may catch up to the 3900X in multi-threaded tasks.
