Question Strange difference in GPU performance with same GPU on two different systems ?

[radvanik]

Hi. On both screenshots my RX 6600 XT. On the left - on one PC, on the right - on another. The drivers are the same with defaults settings, and both systems are Windows 10. The Furmark test results are shown. Can you tell me what could be influencing such a difference in the results? Could it be certain PC components - CPU, motherboard, RAM, PSU, PCIe version (mine is 3.0, the left screenshot is 4.0), or something else?

yes.

you would need to include the complete system specs of both systems with the make & model of ALL components.

also include idle and stressed temperatures of CPU & GPU from both systems.

is the gpu test same?
from left picture its using less gpu cores

yes, 1920x1080 gpu stress test in Furmark

neither system is using a proper power supply.
i would imagine both may be held back some by the available power delivery.

both units are designed for lower end systems,
i wouldn't trust either of them with a mid-high end level GPU connected.
