AMD Ryzen 7 9800X3D Comes with 120W TDP, 5.20 GHz Boost, All Specs Leaked
Specifications of the upcoming AMD Ryzen 7 9800X3D processor were leaked to the web by a Geizhals listing. The chip comes with a processor base frequency of 4.70 GHz, and a maximum boost frequency of 5.20 GHz. The base frequency of 4.70 GHz is a significant increase from the 4.20 GHz of the current 7800X3D, while the maximum boost frequency has moved up a couple of notches from the 5.05 GHz of the 7800X3D. The TDP of the processor is set at 120 W, same as the 7800X3D, and higher than the 105 W revised-spec cTDP of the non-X3D Ryzen 7 9700X.
The specs sheet also confirms that the 3D V-cache size is unchanged generationally. The stacked 3D V-cache die adds 64 MB to the on-die 32 MB L3 cache, which is exposed to software as a 96 MB contiguously addressable L3 cache. The per-core L2 cache size remains 1 MB per core. The biggest contributor to generational gaming performance increases will rest on the increase in frequencies, the new "Zen 5" microarchitecture and any IPC improvements on offer, plus L3 cache performance improvements AMD introduced with "Zen 5." We recently reported a spectacular theory that AMD has designed the 9800X3D such that the stacked 3D V-cache is positioned below the 8-core CPU complex die chiplet, and not above it, which should significantly improve thermals, and clock speeds.

I am not here to judge, I am here to play with hardware with other like minded individuals :)
Personally, I'm not feeling comfortable when I know that with proper tuning and not so much effort my system might work at much better conditions, especially noise-wise. There are people who tune their chips to reach the efficiency sweet spot, which basically requires significant lowering of clocks. I am happy to go with stock clocks at as low voltage as possible, this usually lowers temps and noise significantly.
They should spend less on marketing and other non-crucial company stuff. I really can't understand Intel's decision to lay off people also from R&D. This will backfire badly one day. No way! I want my life to be complicated.
What I have noticed is newer games seem better optimised for CPU's (more threads), but older games are much better for GPU (less VRAM and much lower GPU loads for same visual quality), however rely so much more heavily on fast single threaded performance on CPU.

Not that it matters, if you remember the 7800X3D launch you know how fast the price dropped despite being extremely popular.
VSOC - locked to 1.3v in later BIOS versions only for x3D CPU's (yes, due to CPU's dying), likely due to fragility of the Cache die sitting on top of a 90C CCD die. With Cache die moved underneath the CCD die now, hopefully they can unlock it again.
CPU voltage - locked to 1.2v on all x3D CCD's. Again, with the die repositioning, there's opportunity to unlock this.
Apparently, AMD's implementation of AVX512 is more efficient so not penalized as much in clocks and power, but it must still be consuming more power at the same clocks than other instructions. Honestly, PBO was just AMD's voodoo dance around the TDP and thermal limits. With more things unlocked for overclocking, the voodoo should not be necessary (warranty be damned.)
