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.

Still content with my 5800X3D for the games I'm playing. Will be interesting to see how this new chip pans out. Looking forward to more excellent CPU reviews from the Wizzard
One needs to remember that under ideal cooling, the 7800X3D runs between 4.8-5 GHz at all times as it is not constrained by power at all. Therefore, base clock doesn't mean anything, and a 200 MHz max boost bump isn't much, even if the chip can maintain it 24/7 just like the 7800X3D can.
I don't want to be negative, but this sounds to me like Zen 5% all over again.
Edit: if it was really such a significant improvement, then AMD would have gone with a higher max boost clock, methinks.
Like I've said before, it could be that regular Zen5 is more cache starved than Zen4 after all the architectural changes, which are substantial. Not that I expect any miracles or high numbers.
Purely speculating, of course.
It's now an NPU right ?
On average though with a small relative clock speed bump and the typical Zen 5 gaming uplift I think 10% is about the top end off what you can expect the uplift over the 7800X3D to be across a decent sample size.
Interestingly, PugetBench usually doesn't leak their benchmarks, but they have been very loudly pro-Intel in every case for years now, first downplaying Ryzen and Threadripper leads in productivity, then showing Intel lead way out of proportion, then downplaying Intel failing chips claims (even when Intel admitted them)...
"Third-party benchmark results (via momomo_us) of the upcoming Ryzen 7 9800X3D, in the form of PugetBench results in Adobe Premiere Pro and Davinci Resolve, have been published online. The Ryzen 7 9800X3D sees a multi-threaded improvement of 5% versus its predecessor in Davinci Resolve."
So no magical uplift of productivity in new X3D CPUs as some have prophecised.
46 % faster than a 7700X and 41 % faster than a 9700X in one benchmark.
4 % faster than a 7800X3D in another.
Really, you draw a conlusion from that lol
Anyway, we won't really know whether these specs are true until 7th of November.
