Dimensity 9300 in vivo X100 Pro throttles after 15 minutes in stress test

27 November 2023
As expected from a chip with four performance cores.

Eg for Apple A17 Pro. It has been shown that it is more efficient than the A16 at the same clockspeed. But the performance gains is not as "big." Clearly that's not good for marketing, so Apple pushed the clockspeed more aggressively just so they can show a more "significant" improvement over last year's SoC.

Have a feeling it's the same with Android. The jump in performance with the new node is probably not "huge" so the OEMs are pushing the performance just so they can show better benchmark numbers. So now we have overheating everywhere.

    Does it matter? You're not going to be using your phone at full frequency often. And with normal use, the 4x cores will be very powerful at low frequency, fast enough to finish tasks before overheating and throttling beginning.

SD 8 Gen 3 and... moreIt's not process, it's just both of them were aggressive on clock speed and X4 is not as efficient as X3, just wait for real life implementation of 8G3 Oems will throttle it here and there and battery life will be better than 8G2.

        The Android Freak, 27 Nov 2023Doesn't throttle. But heats up. Nice to know. Can you try listing a source?

Offering SD 888 CPU and SD 870 GPU performance for cheap wouldn't be so bad. 778G and 695 just need to be phazed out by now.

              That's not the way the cpu is intended to be use
              If it's big task,use 4 X-core
              If it's medium, use the 4 A720
              If it's small task, use only 1 or 2 A720

                Seems that Qualcomm and MTK made a BIG screwup along the current TSMC process. Let's see how GPU fares. But seems that SD 8 series and MTK 9000 series are in bad shape, while the SD 7 series is about to commit hara kiri and the MTK 8000 series might be the new flagship

                      Quoted from this very article, and it also says so another time as image description.

                      While the throttling is still bad, the article says something wrong.

                        To see a massive degradation or insane temperatures in both big brands says a LOT of their process.

                        Seems that the process used on SD8 Gen 2 might be the last good process made by TSMC until the next iteration. Their 3 nm on Apple also has overheat issues, but can be fixed with the mature process.

                              The same issue of SD 8 Gen 3. It overheats too during CPU tests. Unlike Apple which has a powerful CPU that can overheat, but can be fixed by adding a vapor chamber, the SD and the Dimensity can't pull the trick.

                              GPU wise both are good, but Snapdragon has the edge big time.

                              Is the same issue on the CPU however. So I guess is time to stick with SD 8 Gen 2 (or Dimensity 8300). Adding more Big cores than 5 is for now a no go. ARM must rethink on what they are doing. Their big cores overheats, the mid ones should be the next small ones and the small ones are just decorations.

                                This speaks more about the OS and optimization. Whether it's performance cores or not, they have variable clockspeed and can be downclocked/throttled when needed (instead of waiting for overheating to happen).

                                  Fa14bi, 27 Nov 2023Looks like to 46% in 15 Minutes to me, not 2 Minutes.They didn't say that the throttled the 46% in 2 minutes. Read the article again or did you even bother? It starts throttling after only 2 minutes after 15. It gets down to 46%. How hard is that to understand dude?
