I understand this might have been shared elsewhere. I'm currently working with a 7800X3D and attempting to use Ryzen Master for optimization. After setting all parameters to their maximums—PPT 420W, TDC 280A, EDC 350A—I ran a multi-thread stress test using Cinebench. The results showed performance peaks at around 20% on PPT, 19% on TDC, and 17% on EDC. This led me to wonder if the CPU isn't being utilized as effectively as it should be.

I'm seeking advice on why this might be happening.

Let me guess: 7800X3d is a gaming-focused chip.
It features a large cache designed to boost the game's master thread speed.
During multithreaded tests, this cache gets emptied repeatedly, and overall performance falls short of what the base 7800 processor could achieve.

I believe the issue relates to building the bus from the chip section to another part, since they rely on a serial mux method that requires buffers to preserve data width. They then increase the bus speed to boost performance, but Intel adds more internal circuits which slows down operations. They also try to overclock internally to keep up with real-time demands.
