What's the max frequency of Xavier NX decoder?

Autonomous Machines Jetson & Embedded Systems Jetson Xavier NX

I can see the frequency of the decoder is 793 Mhz. Is it the max frequency? Can I make it higher to decoder more video?

Hi,
The maximum frequency of hardware engines are listed in
https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3261/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/power_management_jetson_xavier.html#wwpID0E0XO0HA

It is maximum throughput of Xavier NX. For higher performance, may consider Xavier or Orin.

If I want to decoder 4*4k60. YUV444. Which jetson can do it ?

Hi,
It looks like no Jetson platforms can support 4x 4Kp60 for YUV4444. The latest Orin can do 3x 4Kp60 for YUV420. The performance may be lower for YUV444.

Can I overclock the decoder’s frequency? Maybe 1Ghz or 900Mhz is all right ^_^

Hi,

No, this is not supported. The maximum frequency of all hardware engines is listed in power modes. Exceeding the constraint may trigger instability.

I just want to test. Because I see that nano can overclock 30%. Can you show me how to turn the clock?

Hi,

We don’t have manual steps for this.
