VIDEO Comparing RTX 3080 Stability, Temps and Overclocking (SP-CAP/POS-CAP vs MLCC)

Key Highlights from the Video:​

1. Testing Setup:
   • Paul tests four different RTX 3080 models: the NVIDIA Founders Edition, ASUS TUF RTX 3080, Gigabyte Gaming OC, and Zotac Trinity.
   • Initial tests were conducted using Shadow of the Tomb Raider as the benchmarking game, running at 4K with high settings.
2. Temperature and Overclocking:
   • He records the thermals and clock speeds during 15-minute gameplay sessions.
   • The Founders Edition largely operates well below 2 GHz but can reach it with slight overclocking, revealing a max clock of 2040 MHz before instability.
   • The ASUS TUF showed good thermal performance, averaging around 63°C during testing, whereas the Gigabyte and Zotac models demonstrated varying degrees of heat and overclocking stability.
3. Stability Issues and Findings:
   • A consistent theme noted is that while all models are reasonably stable at stock clocks, once pushed beyond 2GHz in overclocking, instability tends to ensue, particularly with the Zotac card, which exhibited the most significant issues during high-performance tests.
   • Paul's testing suggests that while the ASUS and Gigabyte cards maintain stability even at heavy loads, the Zotac’s configuration may not be as robust, possibly due to its capacitor setup.
4. Capacitor Configurations:
   • The video emphasizes the differences between SP-CAP and POSCAP designs, positing that the latter may lead to less effective performance under higher clock conditions.
   • Paul refers to industry discussions around the optimal configurations for power delivery, indicating potential pitfalls with specific designs in real-world applications.
5. Conclusion and Community Insights:
   • The video wraps up with thoughtful insights on the necessity for companies to rethink capacitor arrangements used in PCB designs to mitigate reported instabilities without requiring users to push for extreme overclocking setups.
   • Viewers are encouraged to reflect on their own experiences with these GPUs, discussing any issues related to stability or overclocking in the forum.
