Up to 5% Loss: GeForce RTX 5060 Ti Loses Performance on PCIe 3.0
Fresh tests TechPowerUp confirmed: GeForce RTX 5060 Ti, equipped only eight PCIe 5.0 lanes, loses performance on older motherboards with PCIe 3.0 interface. When operating in PCIe 3.0 x8 mode the card shows up to 5% FPS drop, which may be critical for some users.
On modern platforms with PCIe 4.0 or 5.0 no problems are observed - performance remains stable. In the test, the RTX 5060 Ti 16 GB model was tested in three modes:
-
PCIe 5.0 x8 (100% performance)
-
PCIe 4.0 x8 (98%)
-
PCIe 3.0 x8 (96%)
A 4% reduction is observed with resolution 1920 × 1080, which is especially sensitive on systems where every FPS counts.
Reason - low bandwidth PCIe 3.0 x8, which limits the amount of data between the video card and the processor. This configuration is typical for older platforms based on Intel 10th Gen and AMD AM4. In heavier scenes, especially those with high textures and fast data streaming, PCIe bottleneck may become noticeable.
However, even with this reduction, the RTX 5060 Ti still shows solid results and outperforms many previous-generation models. But for users planning to upgrade the graphics card without replacing motherboard, it is worth considering this nuance. Especially if you are using a platform with PCIe 3.0 and plan to work under maximum load conditions GPU.
