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.

9800X3D will be faster than 7800X3D for sure both with ipc and mhz.
I had not heard about the cache being under the cores so that is pretty cool!
Let's wait until AMD decides to use TSMCs 3nm, for a change.
Seems too optimistic but I had no choice after selling my 7800X3D at profit :D
Guru3d benched around 8-9% benefit for 9000 over 7000 clock for clock (Cinebench). CPUZ bench reflects sort of the same story.
Should be a more snappy CPU over predecessor, while offering better objective performance in pretty much everything else.
Remember what happened before the 9000 launch.
AMD did nothing with the 7000's.
AMD launched the 9000's.
No one/few saw the 9000's worthwhile and bought 7000's instead.
AMD learned a lesson and cut/stopped 7000X3D production in time for the 9800X3D launch. Possibly using that production capacity for the latter anyway.
In the meanwhile, the 7000X3D prices goes up due to lack of supply. All three models, even the 12 core which have no successor for months is currently at $600.
Now some people interpret this as the 9800X3D costing $600. :laugh:
It can be disabled through PowerShell, thankfully. Even if it doesn't work, I still don't want that crap switched on.
I said measurable, I have a feeling it's around 6-7% without ReBAR but it's not really enough to worry about, just something to understand is happening.

That aside, I heard on Reddit that EU users are not getting Recall (due to GDPR), but I can't confirm that myself.
The 5700X3D has frequently sold for under $190 and is only $209 right now, which is a massive 40% price cut for not even a 10% performance drop.
If you're not buying a 4090 and instead have a more modest GPU like a 7700XT or a 4070 then spending more than double on a 7800X3D platform isn't going to net you any improvement at all.
how about using slower GPU and maybe 1440p resolution?
1-3% difference maybe? Sure sure, just go and buy 4090 and u maybe get +10% even 15% if gaming 1080p..
Or try 720p, difference can be even higher then, +25%? Thanks, at least one see the facts
And tuning X3D is boring AF.
Now it wont be, hopefully.
If you like to run your CPU at stock, all the power to you.
