There is a big difference in CPU power consumption for the roasted chicken test on the CPU of the Legion R9000P 2023 (R9-7945HX) with different versions of AIDA64.

I have a Lenovo Legion R9000P 2023 model (R9-7945HX) computer and wanted to test its system stability, so I ran a Stress FPU test in Beast mode. However, during the test, I found that using different versions of AIDA 64 resulted in different CPU power readings with significant differences. AIDA Extreme v6.85.6300 and v6.88.6400 couldn't push the CPU power, but older versions like v6.8 could. I would like to know what the differences are between AIDA's old and new versions and why this is happening.

Thank you very much and look forward to your reply.

When running the CPU roast test using v6.88.6400 and 6.85.6300, CPU power runs lower compared to the CPU power in previous versions.

Can you see lower temperatures reached with the newer AIDA64 versions too?  Maybe it's not the System Stability Test that has an issue, but the CPU power draw cannot be measured properly?

The new version of AIDA64 can make TDC value always run at the TDC Limit, but the APU Socket power is comparatively low (especially in the initial Boost stage). On the other hand, the old version of AIDA64 only tops at the TDC Limit in the first few tens of seconds, and the APU Socket power can run very high. Additionally, the CPU temperature will also reach the Thermal Limit when running the CPU roast test on both old and new versions. At the same time, I also used Prime95 v29.8 and AMD TCT tool to run the CPU roast test, and the CPU power can run consistently with the behavior of the old version of AIDA64. Through experimentation, it was found that this problem seems to be replicable only in v6.85.6300 and v6.88.6400.

It can be seen from the release notes of AIDA64 v6.85.6300 that it has been updated with AVX-512 optimized stress testing for AMD Zen 4 based Ryzen 7000 Series processors. In contrast, the release notes for v6.80.6200 mention AVX-512 accelerated benchmarks for AMD Zen 4 based Ryzen 7000 Series processors. Could this difference in updates have caused the issue?

I have the same issue, we try the prime95 test tool no this issue happened.
