💡 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 RTX 3060 Ti GPU Score: 14,500 · Intel Core i5-12600K CPU Score: 27,000. Ratio: 1.86x — imbalance present at 1440p.
🔧 1080p vs 4K Impact
At 1080p, bottleneck is 43% (GPU). At 4K it shifts to 26% (CPU). Higher resolution reduces CPU bottleneck by shifting load to the GPU.
Resolution-by-Resolution Analysis
1080p Full HD
The NVIDIA RTX 3060 Ti is the limiting factor. Your Intel Core i5-12600K 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 RTX 3060 Ti is the limiting factor. Your Intel Core i5-12600K 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 Intel Core i5-12600K cannot feed the NVIDIA RTX 3060 Ti fast enough. The GPU sits idle 26% of the time at this resolution. To reduce this, increase to 4K or upgrade your CPU.
What This Bottleneck Means for Your Gaming
The NVIDIA RTX 3060 Ti has a performance score of 14,500 and the Intel Core i5-12600K scores 27,000. The score ratio is 1.86x, 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 15% (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.
