What the specs say they'll do and what they actually do are often very different realities in my experience.

I've seen thermal throttling happening at 60°C because overall, the chip is cool, but one core is maxing or two cores are maxing. Which is common in game dev with your primary thread feeding a GPU with command buffer queues and another scheduling the main game loop.

Even when water cooled or the high end air cooling on my server blades, I see that long term, the system just hits a trade-off point of ~60-70°C and ~85% max CPU clock even when the cooling system is industry grade, loud as hell, and has an HVAC unit backing it. Probably part of why scale out is so popular to distribute load.

When I give real work to any iGPU's on these systems, I see the temps bump 5-10°C and clocks on the CPU cores drop a bit. Could be drivers, could be temp curves, I would think these fancy cooling systems I'm running are performing well though. shrug
