💡 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 3090 Ti GPU Score: 26,500 · Intel Core Ultra 7 265K CPU Score: 48,000. Ratio: 1.81x — imbalance present at 1440p.
🔧 1080p vs 4K Impact
At 1080p, bottleneck is 41% (GPU). At 4K it shifts to 28% (CPU). Higher resolution reduces CPU bottleneck by shifting load to the GPU.
Resolution-by-Resolution Analysis
1080p Full HD
The NVIDIA RTX 3090 Ti is the limiting factor. Your Intel Core Ultra 7 265K 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 3090 Ti is the limiting factor. Your Intel Core Ultra 7 265K 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 Ultra 7 265K cannot feed the NVIDIA RTX 3090 Ti fast enough. The GPU sits idle 28% 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 3090 Ti has a performance score of 26,500 and the Intel Core Ultra 7 265K scores 48,000. The score ratio is 1.81x, 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 13% (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.
