Six Cores vs. Eight Cores: Battlefield 6 Benchmark Results Are Surprising

For the last few years, the prevailing wisdom in the PC gaming community has been that six cores just aren't enough for a smooth experience, and that investing in a higher core-count CPU is essential for future-proofing. However, new benchmarks from Hardware Unboxed show that the real-world gaming performance difference between modern 6-core and 8-core processors is minimal, with the key factors being individual core performance and architecture, not the number of cores.

The experiment was run in one of the most resource-intensive games on the market, Battlefield 6. A comparison of the newest AMD Ryzen 5 9600X (6 cores) and Ryzen 7 9700X (8 cores) at low graphical settings revealed a mere 4% performance gap in favor of the more expensive chip. Even when switching to Ultra settings, which puts a heavier load on the system, the lead never exceeded 9-10% — a difference that isn't proportional to the increased cost and core count.

A more telling comparison came from pitting different architecture generations against each other. The 6-core Ryzen 5 7600X, built on the Zen 4 architecture, hands-down outperformed the previous-generation 16-core flagship, the Ryzen 9 5950X. This clearly demonstrates that an older architecture can't compete with modern solutions, even with a massive core-count advantage. The common belief that 8 cores are critical for multitasking — like streaming or recording gameplay while you play — was also debunked, as tests showed no substantial benefits in these scenarios.

Interestingly, even an 8-core processor from 2018, the Ryzen 7 2700X, still manages to deliver acceptable performance in Battlefield 6 with smooth gameplay, proving that overall architectural efficiency is what truly counts for gaming. All testing was done using a GeForce RTX 5090 graphics card to eliminate GPU bottlenecks and create maximum load on the central processor, with performance measured at both 1080p and 1440p resolutions.

The takeaway is pretty clear: when building a gaming PC, there's little reason to shell out extra cash for an 8-core CPU unless you're doing professional work like rendering. For modern gaming, six cores of the latest generation are more than enough, and your money is much better spent on a more powerful graphics card or faster RAM.
