💡 Upgrade Recommendation
Your CPU is ready for a GPU upgrade. Consider moving to a higher-tier GPU if you want more performance.
📊 Performance Score Ratio
NVIDIA GTX 1660 Super GPU Score: 8,000 · AMD Ryzen 5 5600X CPU Score: 20,000. Ratio: 2.50x — imbalance present at 1440p.
🔧 1080p vs 4K Impact
At 1080p, bottleneck is 45% (GPU). At 4K it shifts to 0% (Balanced). Higher resolution reduces CPU bottleneck by shifting load to the GPU.
Resolution-by-Resolution Analysis
1080p Full HD
The NVIDIA GTX 1660 Super is the limiting factor. Your AMD Ryzen 5 5600X has headroom, which is the ideal scenario for gaming. Ideal scenario — your GPU is fully utilised. Upgrade GPU for more performance.
1440p QHD
The NVIDIA GTX 1660 Super is the limiting factor. Your AMD Ryzen 5 5600X has headroom, which is the ideal scenario for gaming. Ideal scenario — your GPU is fully utilised. Upgrade GPU for more performance.
4K Ultra HD
Excellent pairing at this resolution. Both components operate near their optimal load range. Excellent balance — both components are near optimal load.
What This Bottleneck Means for Your Gaming
The NVIDIA GTX 1660 Super has a performance score of 8,000 and the AMD Ryzen 5 5600X scores 20,000. The score ratio is 2.50x, 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 38% (GPU limited). A bottleneck above 20% means meaningful performance is being left on the table. An upgrade is worth considering.
Your CPU is ready for a GPU upgrade. Consider moving to a higher-tier GPU if you want more performance.
