NVIDIA’s flagship GeForce RTX 5090 shows significant performance issues when it doesn’t utilize its full PCIe 5.0 x16 bandwidth. Recent tests reveal that the GPU experiences a performance drop of over 25% in rendering tasks. This decline in efficiency raises concerns for gamers and professionals who rely on this powerful graphics card for demanding applications.
When the RTX 5090 operates at less than full bandwidth, users may experience noticeable lag during gameplay and content creation. This limitation could hinder the card’s ability to deliver its promised performance benefits. As technology advances, understanding the importance of PCIe bandwidth becomes crucial for maximizing the capabilities of high-end GPUs like the RTX 5090.
