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.

It seems AMD are busy pushing voltages and clocks like Intel have been, which is a shame. One of the best things about most of the Ryzen 7s and below was the efficiency - which directly translated to quiet coolers and compatibility with SFF cases.
I'm sure 5.2GHz is nice, but realistically, 5.05GHz at 15% lower power draw would be nicer - I guess PBO+ is an option for anyone not using an A-series board, and realistically nobody should be using an A-series board with what is presumably this relatively high-end chip that shouldn't have it's PCIe lane bandwidth to the PEG slot halved unnecessarily.
9800X3D is going to demolish it for gaming and use 1/2 the power doing so. Intel needs some new engineers methinks, need to keep the competition going.
AMD does have room for improvement though, their idle power is still way too high (20W higher than Intel now) and their boot times are still quite slow.
This is a thermally improved (allegedly) design of a Zen5 take of the 7800X3D with a slight frequency Increase. Doing the math on what to expect here considering we already know what Zen5 does in comparison to Zen4 is really not rocket science.
Considering how quiet AMD has been about this the gains over the 7800X3D are probably too low to tout. You can't pull the same energy efficiency card with 9000 vs 7000 because the 7800X3D already is incredibly efficient.
Ergo, this.
That’s… not how frequency scaling works. It’s not a line. There’s 200Mhz between 9950X and 9700X. There is no difference in performance even at 720p with a 4090. At any reasonable resolution the story is (obviously) even sadder. I mean, I assume we are discussing game performance here and not applications since X3D chips are almost strictly gaming ones. Even if AMD could ensure 5.4 boost on every chip reliably there really isn’t any reason for them to go for it. They are competing with themselves.

Although I still stand by my case that I believe the 5.4GHz would push the improvement to 10% more often than not.
And yeah, gaming of course.
I guess the one thing the extra 150MHz does for this 9800X3D is improve productivity benchmark scores, which is dumb because the X3D chips have always been awful performance/$ offerings compared to the cheaper, faster regular X versions.
Realistically, for gamers buying this gamer-focused CPU, what we're getting is a 20% higher power draw for almost no benefit. We'll have to wait for reviews to see if that's true or not, though....
I guess if you want the (almost) best gaming chip and productivity chip at the same time, the 9950X3D is probably the only viable candidate which is likely to lose only a couple of percent to the 9800X3D and 9950X in their preferred tasks respectively. Performance/$ goes out the window, but if you actually need the productivity performance you can presumably justify the cost hike with the returns it will net you in time saved.
I am not sure one can call the reliance on XBox Game Bar and Windows Game Mode a driver. The PPM provisioning that comes with the chipset drivers is apparently not enough by itself.
