AMD’s next gaming CPU monster has appeared in the wild, and it’s packing some serious firepower. The Ryzen 9 9950X3D2 showed up on PassMark and Geekbench databases this week with a whopping 192MB of total L3 cache, making it the first mainstream desktop processor to feature 3D V-Cache stacked on both chiplets. The question everyone’s asking: is this engineering flex actually useful for gaming, or just an expensive party trick?
What Makes the 9950X3D2 Different
The regular Ryzen 9 9950X3D, which launched in March 2025, already impressed with 128MB of L3 cache by stacking 64MB of 3D V-Cache underneath one of its two Core Complex Dies. The 9950X3D2 takes this concept further by adding that same 64MB cache layer to the second CCD as well, doubling the effective cache from 96MB to 192MB total across both chiplets.
According to the leaked specifications, the 9950X3D2 maintains the same 16-core, 32-thread configuration as its predecessor but with slightly reduced boost clocks at 5.6 GHz compared to the 9950X3D’s 5.7 GHz maximum. The PassMark listing confirms a 170W TDP, though earlier rumors suggested it might reach 200W under full load. AMD accomplished this dual-cache design by placing the V-Cache underneath the CCDs rather than on top, a change introduced with the Zen 5 architecture that allows better thermal management and power efficiency.
Benchmark Numbers Tell a Modest Story
The leaked benchmark results paint an interesting picture. On PassMark, the 9950X3D2 scored 71,585 in multi-core performance and 4,716 in single-core tests. These numbers land within the margin of error compared to the standard 9950X and 9950X3D, suggesting the extra cache provides minimal benefit in synthetic benchmarks.
Geekbench tells a slightly better story. The 9950X3D2 achieved 3,456 points in single-core testing, the highest score in Geekbench’s processor database, and 21,062 points in multi-core workloads. That single-core lead represents roughly a 2 percent improvement over the existing 9950X3D, which aligns with expectations for a chip that essentially offers more of the same rather than revolutionary changes.
Performance Comparison
| Processor | L3 Cache | Boost Clock | Geekbench Single-Core |
|---|---|---|---|
| Ryzen 9 9950X3D2 | 192MB | 5.6 GHz | 3,456 |
| Ryzen 9 9950X3D | 128MB | 5.7 GHz | ~3,380 |
| Ryzen 7 9800X3D | 96MB | 5.2 GHz | ~3,100 |
The Gaming Reality Check
Here’s where things get complicated. For pure gaming purposes, the Ryzen 7 9800X3D remains AMD’s champion despite having “only” 96MB of cache and eight cores instead of sixteen. Games generally don’t scale well across multiple chiplets due to inter-CCD latency, meaning a game running on the 9950X3D2 would ideally stay on one CCD with its 96MB of cache rather than jumping between both.
The scheduling problem gets worse with dual V-Cache configurations. When Windows assigns tasks to different cores across separate chiplets, those cores don’t share cache. If a game thread starts on CCD0 and Windows moves it to CCD1, all that cached data becomes useless, forcing the processor to fetch it again from slower memory. This results in inconsistent performance that can actually feel worse than a single-CCD chip despite the impressive specifications on paper.
AMD itself acknowledged this limitation back in January 2025 when asked about dual V-Cache configurations. According to AMD representatives, such a processor would be “too expensive” and games wouldn’t benefit from a second CCD with 3D V-Cache to the same extent as the initial jump from 32MB to 96MB on a single chiplet. The company specifically designed the 9800X3D with one CCD to avoid these scheduling headaches entirely.
Who Actually Benefits From This
While gamers might not see massive improvements, workstation users and content creators could find value in the 9950X3D2. Memory-intensive professional applications like video encoding, 3D rendering, and scientific simulations can leverage all sixteen cores simultaneously and benefit from having that massive cache pool available across both chiplets.
The early benchmarks suggest approximately 2 percent faster performance in cache-sensitive workloads compared to the 9950X3D. That might not sound like much, but for professionals running overnight renders or processing massive datasets, those gains add up. The question becomes whether that 2 percent improvement justifies what will likely be a significant price premium over the already expensive 9950X3D.
The Price Problem Nobody Wants to Talk About
The standard Ryzen 9 9950X3D currently sells for around $680, already a hefty investment for most PC builders. Industry analysts expect the 9950X3D2 to command at least $200 more, potentially reaching the psychologically significant $899 or even $999 price point as a halo product. AMD might position this chip as an ultra-premium option for enthusiasts and professionals who want the absolute best specifications regardless of practical gaming benefits.
For context, the beloved Ryzen 7 9800X3D launched at $479 and delivers better gaming performance in most titles due to its single-CCD design avoiding scheduler issues. Spending double or triple that amount for the 9950X3D2 makes sense only if you specifically need those extra cores for production work and can benefit from the additional cache in professional applications.
CES 2026 Launch Looking Likely
The timing of these benchmark leaks suggests AMD plans to announce the 9950X3D2 at CES 2026 in early January. The processor appeared on a Galax B850M motherboard paired with 96GB of DDR5 memory, indicating motherboard partners are already testing BIOS configurations ahead of launch. These samples getting into benchmark databases typically happens a few weeks before official announcements.
AMD is also expected to reveal the Ryzen 7 9850X3D at the same event, a higher-clocked version of the 9800X3D boosting up to 5.6 GHz. That chip makes more sense for gamers who want a bit more performance without the complexity of dual-chiplet configurations. Early retail listings showed prices between $550 and $600, though those are likely placeholder numbers rather than final MSRP.

Why AMD Built This Anyway
If the gaming benefits are questionable and the price will be astronomical, why does the 9950X3D2 exist? The answer likely involves competition, prestige, and future-proofing. Intel has reportedly been working on its own massive cache solutions for upcoming processors, so AMD wants to demonstrate technical leadership even if the practical benefits don’t justify the cost for most users.
There’s also the simple fact that AMD can build this chip now that they’ve solved the thermal challenges of placing V-Cache underneath the cores. The second-generation 3D V-Cache architecture introduced with the 9800X3D runs cooler and supports overclocking, making dual-cache configurations viable from an engineering perspective. Just because something is possible doesn’t always mean it’s practical, but it does make for impressive marketing materials.
Frequently Asked Questions

No, despite having twice the cache and double the cores, the 9800X3D will likely remain the superior gaming chip. Games typically run on a single Core Complex Die, so the 9950X3D2’s second cache-equipped chiplet provides minimal benefit while introducing potential scheduling issues. The 9800X3D’s single-CCD design avoids these problems entirely and costs significantly less.
How much will the Ryzen 9 9950X3D2 cost?
While AMD hasn’t announced official pricing, industry analysts expect the 9950X3D2 to cost between $899 and $999 based on the complexity of manufacturing dual V-Cache chiplets. The regular 9950X3D currently sells for around $680, and adding V-Cache to the second CCD likely adds $200-300 to production costs.
What is 3D V-Cache and why does it matter?
3D V-Cache is AMD’s technology for stacking additional L3 cache memory directly on top of or underneath processor cores. This extra cache reduces the need to access slower system RAM, dramatically improving performance in games and applications that need to rapidly access large amounts of data. The second-generation design used in Zen 5 processors places the cache underneath the cores for better thermal performance.
When will the Ryzen 9 9950X3D2 be available?
Based on the recent benchmark leaks and typical AMD release schedules, the 9950X3D2 will likely be announced at CES 2026 in early January with availability following in late Q1 or Q2 2026. The appearance of samples on motherboard vendor test systems suggests launch preparations are already underway.
Will the 9950X3D2 work on existing AM5 motherboards?
Yes, the Ryzen 9 9950X3D2 uses the same AM5 socket as other Ryzen 9000 series processors. Existing motherboards will support it with a BIOS update, though AMD may recommend higher-end boards with robust VRM designs to handle the chip’s power requirements. The leaked specifications show testing on B850 chipset boards, suggesting broad compatibility.
What’s the difference between 9950X3D and 9950X3D2?
The “2” suffix indicates dual V-Cache configuration. The standard 9950X3D has 3D V-Cache stacked on only one of its two Core Complex Dies, giving it 128MB total L3 cache. The 9950X3D2 adds V-Cache to both CCDs, doubling the cache to 192MB. This comes with slightly lower boost clocks at 5.6 GHz versus 5.7 GHz on the standard model.
Should I wait for the 9950X3D2 or buy a 9800X3D now?
For gaming purposes, buy the 9800X3D now. It delivers better gaming performance thanks to its single-CCD design and costs significantly less. Only consider the 9950X3D2 if you need sixteen cores for professional workloads like video editing or 3D rendering and can justify spending potentially double the price for modest productivity gains.
The Enthusiast’s Dilemma
The Ryzen 9 9950X3D2 represents AMD pushing the boundaries of what’s technically possible with current manufacturing processes. Having 192MB of L3 cache on a mainstream desktop processor would have seemed impossible just a few years ago, yet here we are with benchmark leaks proving it exists. The engineering achievement deserves recognition even if the practical benefits don’t match the impressive specifications.
For most gamers, this chip will be curiosity rather than a realistic purchase consideration. The combination of high pricing, potential scheduling issues, and minimal gaming advantages compared to the cheaper 9800X3D makes it a tough sell. Content creators and professionals with specific workflows that can leverage all sixteen cores plus massive cache pools might find value, but they represent a tiny fraction of the overall market.
What this launch really signals is AMD’s confidence in its position at the top of the gaming CPU market. The company can afford to experiment with halo products like the 9950X3D2 because the core lineup from the 9600X up through the 9800X3D already dominates in their respective price categories. Whether anyone actually needs 192MB of cache on a desktop processor is almost beside the point when the real message is that AMD has the technical capability to build it if they want to.
