The differences in the vendor-approved CPU and GPU OPPs for the standard Rockchip RK3588 variant [1] and the industrial Rockchip RK3588J variant [2] come from the latter, presumably, supporting an extended temperature range that's usually associated with industrial applications, despite the two SoC variant datasheets specifying the same upper limit for the allowed ambient temperature for both variants. However, the lower temperature limit is
RK3588 is rated for 0-80°C, RK3588J for -40-85°C, c.f. Recommended Operating Conditions, Table 3-2, Ambient Operating Temperature.
Indeed, which is why I specifically wrote "specifying the same upper limit", because having a lower negative temperature limit could hardly put the RK3588J in danger of overheating or running hotter. :)
""" despite the two SoC variant datasheets specifying the same upper limit for the allowed temperature for both variants """
is incorrect. The whole range is different, yes it's only a 5°C difference for the upper limit, but they still are different.
I just commented on this separately, with a couple of datasheet screenshots, before I saw your latest response. Please, have a look at that message.
I see, I had a v1.3 datasheet opened:

Yup, the v1.6 of the RK3588 datasheet increased the upper ambient temperature limit from 80 to 85 oC.
Interestingly, it seems the RK3588S (still?) has a smaller operating range:

Oh, that's quite interesting, I had the v1.5 as the newest version. The v1.6 of the RK3588S datasheet actually lowered the upper ambient temperature limit from 85 down to 80 oC.
