📊 Performance Score Ratio
AMD RX 6600 GPU Score: 9,500 · AMD Ryzen 5 5600 CPU Score: 18,000. Ratio: 1.89x — imbalance present at 1440p.
🔧 1080p vs 4K Impact
At 1080p, bottleneck is 45% (GPU). At 4K it shifts to 24% (CPU). Higher resolution reduces CPU bottleneck by shifting load to the GPU.
Resolution-by-Resolution Analysis
1080p Full HD
The AMD RX 6600 is the limiting factor. Your AMD Ryzen 5 5600 has headroom, which is the ideal scenario for gaming. Ideal scenario — your GPU is fully utilised. Upgrade GPU for more performance.
1440p QHD
The AMD RX 6600 is the limiting factor. Your AMD Ryzen 5 5600 has headroom, which is the ideal scenario for gaming. Ideal scenario — your GPU is fully utilised. Upgrade GPU for more performance.
4K Ultra HD
The AMD Ryzen 5 5600 cannot feed the AMD RX 6600 fast enough. The GPU sits idle 24% of the time at this resolution. To reduce this, increase to 4K or upgrade your CPU.
What This Bottleneck Means for Your Gaming
The AMD RX 6600 has a performance score of 9,500 and the AMD Ryzen 5 5600 scores 18,000. The score ratio is 1.89x, meaning there is a meaningful performance gap between them. The weaker component will limit the stronger one.
At 1440p — the most popular gaming resolution in 2026 — the bottleneck is 16% (GPU limited). A 10–20% bottleneck is moderate. You may notice slightly lower FPS than the GPU is capable of.
Your CPU is ready for a GPU upgrade. Consider moving to a higher-tier GPU if you want more performance.
