AMD working on new X3D V-cache mobile chip for gaming laptops, leaker claims — Ryzen 7 9800HX3D could launch with 8 cores, 16 threads, and 96MB cache
A new 3D V-Cache-equipped CPU is reportedly in the works and could arrive as a mobile counterpart to the Ryzen 7 9800X3D. According to prominent tech industry insider Golden Pig Upgrade Pack on Weibo, the Ryzen 9 9800HX3D is expected to enter mass production in Q4 2026, with a potential launch at CES 2027. The chip is rumored to feature an 8-core, 16-thread configuration with boost clock speeds of up to 5.1 GHz, and 96MB of L3 cache.
It is also claimed that the processor was previously rumored to launch as the Ryzen 7 9755HX3D; however, it seems that the company might settle on the 9800HX3D. This essentially brings the branding in line with the desktop Ryzen 7 9800X3D. The chip could follow the same cache configuration with an eight-core CCD with 32MB of native L3 cache and a 64MB 3D V-cache stack.
Currently, AMD’s most powerful 3D V-Cache-equipped mobile processor is the Ryzen 9 9955HX3D, featuring 16 cores, 32 threads, and a maximum boost clock of 5.4 GHz. It also offers a substantially higher L3 cache at 128MB and a configurable TDP of 55-75W.

While AMD hasn’t confirmed any details, the Ryzen 7 9800HX3D could likely be featured on premium gaming laptops that don’t require the additional cores of the flagship 9955HX3D. An 8-core Zen 5 processor paired with 3D V-Cache could strike a better balance between gaming performance, power consumption, and overall system cost.
The rumored processor also aligns with AMD’s recent approach of refreshing its X3D lineup instead of introducing new gaming CPUs. Similar to the recently announced Ryzen 9 9950X3D2 and the reintroduction of the 5800X3D, the 9800HX3D appears to build on an existing design while bringing AMD’s latest branding and gaming-focused cache technology to another product tier.
The introduction of the 9800HX3D would also give laptop manufacturers a new gaming-focused option that is positioned below the flagship 9955HX3D. The processor would likely attract consumers seeking desktop-class gaming performance without paying the premium typically associated with 16-core mobile CPUs. As always, the rumored specifications and launch timeline should be treated with caution until AMD makes an official announcement.
