NVIDIA's newest graphics card has a major weakness that could upset many users. The RTX 5090 needs maximum connection speed to work properly. Video editors face the biggest problems when their computer cannot provide enough data flow. Puget Systems tested the expensive graphics card and found shocking results. Adding other computer parts can make the RTX 5090 run much slower.
Most computer boards have one fast slot for graphics cards. The RTX 5090 works best when it gets all the available connection lanes. Adding network cards or other devices forces the computer to split the connection speed. This sharing reduces how fast information travels to the graphics card. The performance drop becomes very noticeable during heavy work.
After Effects users saw more than 10 percent slower speeds when connection quality dropped. DaVinci Resolve suffered even worse with over 20 percent performance loss. The graphics card struggled when it received only four connection lanes instead of sixteen. Video editing software demands constant data transfer between the graphics card and computer memory. Lower connection speeds create bottlenecks that hurt productivity.
Gaming and artificial intelligence tasks showed different results during testing. Unreal Engine games ran almost the same regardless of connection speed. AI programs like Llama also maintained steady performance with reduced bandwidth. These applications rely more on graphics card memory than constant data transfer. The built-in memory handles most processing without needing external help.
Content creators should carefully plan their computer setups to avoid these issues. Home gamers probably will not notice any problems during regular use.
