MHz GT0 looks good to me because that will keep the unit adjacent to the value. Something like this:

intel-gpu-top: Intel Meteorlake (Gen12) @ /dev/dri/card0 -      0/     0 MHz GT0;      100% RC6 GT0;      0/     0 MHz GT1;      100% RC6 GT1;  0.00/ 4.98 W;        0 irqs/s

Let me know if that's not what you meant.

Thanks,
Umesh
