AMD Product Pages Say Upcoming 7950X3D and 7800X3D "Unlocked for Overclocking"

The product pages of the upcoming AMD Ryzen 9 7950X3D and Ryzen 7 7800X3D "Zen 4" processors went online, which say that the two chips are unlocked for overclocking. This normally implies that the processor has an unlocked base-clock multiplier, which makes it easy to overclock. The previous-generation Ryzen 7 5800X3D processors came with locked base-clock multipliers, making them complicated to overclock. Both the 16-core/32-thread 7950X3D and the 8-core/16-thread 7800X3D come with a TDP rating of 120 W, which for the 7950X3D is significantly lower than the 170 W that the 7950X is rated at. It's also worth noting that the T-junction max (TJmax) value is lower, at just 89C, compared to 95C of the 7950X and 7700X.

Slated for a February 2023 market release, the two chips introduce stacked 3D vertical cache technology (3DV cache). The 7800X3D comes with 64 MB of 3DV cache stacked on top of the 32 MB of on-die L3 cache, taking its L3 cache size to 96 MB, and total cache (L2+L3) to 104 MB. On the other hand, the 7950X3D and the 12-core/24-thread 7900X3D only come with the 3DV cache memory on one of the two "Zen 4" CCDs. The first CCD has 96 MB of L3 cache (including the 3DV cache), while the second CCD is a standard "Zen 4" CCD with just 32 MB of on-die L3 cache. For these chips, the L3 cache adds up to 128 MB, and total cache to 140 MB for the 7900X3D, and 144 MB for the 7950X3D.

Update Jan 24th: AMD updated their product pages to remove this field altogether. It looks like we'll have to wait a bit for AMD to finalize its specs.
