For our temperature testing, we measure the peak GPU core temperature under load. A reading under load comes from running Cyberpunk 2077 for 30 minutes.
No comparison data also means we can't yet know for sure how good the Pulse's cooler is, but with a GPU temperature of 69C, it looks good enough. The hot spot is higher, at 90C, but we saw similar from the Pulse RX 7600 non-XT as well and it's still well within safe limits.
