AMD Ryzen 7 7700X3D leaked, 8 cores up to 4.5 GHz, and 96MB L3 cache

AMD may be preparing yet another Zen 4 processor with 3D V-Cache for the AM5 platform. Hardware leaker chi11eddog has shared specifications for an unannounced chip on X, the Ryzen 7 7700X3D, which Videocardz has since corroborated.

The Ryzen 7000 series is built on AMD's Zen 4 architecture and already has a fairly extensive X3D lineup, which currently includes six chips ranging from the Ryzen 9 7950X3D at the top all the way down to the Ryzen 5 7500X3D. The Ryzen 7 7700X3D would slot in as the seventh member of the family, sitting just below the popular Ryzen 7 7800X3D in the lineup.

According to the leak, the chip will feature 8 cores and 16 threads based on the Zen 4 core architecture. It carries 32MB of L3 cache on the CCD with an additional 64MB stacked on top via 3D V-Cache technology, bringing the total to 96MB. That part of the spec sheet is identical to the 7800X3D. Where it differs is in clock speeds: the 7700X3D is listed at a 4.0 GHz base and a 4.5 GHz boost, compared to the 7800X3D's 4.2 GHz base and 5.0 GHz boost.

The TDP for this "new" CPU is listed at 120W. The clock speed reduction is meaningful on paper, but given how much gaming performance relies on cache rather than raw frequency, the real-world difference is not expected to be drastic. It is plausible that AMD is repurposing some of the old silicon, so it is lower binned than the Ryzen 7 7800X3D.

The obvious reason AMD is bringing this chip to market is price. The 7800X3D currently retails for around $360, and speculation puts the 7700X3D somewhere around $300, which would make 96MB of 3D V-Cache accessible to a much wider audience of budget-conscious builders. This is also not a new strategy for AMD. The company did something similar with AM4 and the Ryzen 7 5700X3D, a lower-binned version of the 5800X3D that turned out to be a fantastic value gaming chip.

It is worth noting that AMD has clearly been focused on expanding the X3D lineup across the board. On the high end, the company recently launched the Ryzen 9 9950X3D2 Dual Edition, featuring 16 cores, 208MB of total L3 cache, and dual-stacked cache dies. The 7700X3D would represent the other end of that push, bringing 3D V-Cache to a more accessible price point.

Nothing is official yet, and AMD has not confirmed the chip. Keep an eye out for our coverage as this one develops.
