AMD has just released two new processors with their latest 3D V-Cache technology. The Ryzen 9 9950X3D and 9900X3D processors feature the second generation of this innovative cache design, which has been physically repositioned to sit below the CPU die. This new placement allows the physical cores to be closer to the integrated cache, helping both chips run cooler while offering better overclocking potential.
One major improvement in these new processors is the thermal efficiency. By moving the 3D V-Cache underneath the CPU die rather than stacking it on top, AMD has solved previous heating issues that limited performance. This design change means gamers and content creators can expect better sustained performance during long sessions without throttling problems.
Both the 9950X3D and 9900X3D come with substantial L2 and L3 caches enhanced by the 3D V-Cache technology. Interestingly, AMD only implemented the 3D V-Cache on select CCDs (Core Complex Dies) rather than all available ones, as their testing showed this selective approach provided optimal performance benefits without unnecessary cost increases.
What’s New With AMD’s 2nd Gen 3D V-Cache?
AMD’s Ryzen 9 9950X3D and Ryzen 9 9900X3D mark a major leap forward in CPU architecture, thanks to the second-generation 3D V-Cache. If you’re familiar with AMD’s first-gen 3D V-Cache, you already know it made waves by boosting gaming performance through extra L3 cache stacked vertically on the chip. This time around, AMD didn’t just refine the tech—they doubled down, quite literally.
The big news? AMD’s new X3D chips are stacking 3D V-Cache on both CCDs (Core Complex Dies), rather than limiting it to a single CCD like the previous generation. That means each CCD on these processors carries a whopping 96MB of L3 cache, resulting in up to 192MB of L3 cache in total. Combined with generous L2 cache, the total cache can reach up to 208MB on the Ryzen 9 9950X3D. That’s an insane amount of fast, on-die memory aimed squarely at gamers and content creators who need every ounce of performance.
Ryzen 9 9950X3D: A Gaming Powerhouse
The Ryzen 9 9950X3D sits comfortably at the top of AMD’s Zen 5 stack. With 16 cores and 32 threads, this beast of a processor boasts a base clock of 4.3 GHz and boosts up to 5.7 GHz. But what makes it special is the cache—the 3D V-Cache unlocks new levels of efficiency and latency reduction, giving this CPU the edge in gaming scenarios where rapid access to large datasets matters.
In gaming benchmarks, the 9950X3D is delivering impressive frame rates that outpace Intel’s Core Ultra 9 285K in many titles. Popular esports games like CS2 and competitive shooters see noticeable boosts, while large open-world RPGs that thrive on high cache capacity—like Starfield—run smoother, with fewer stutters and better minimum frame rates.
Key Specs of Ryzen 9 9950X3D:
- Cores/Threads: 16/32
- Base Clock: 4.3 GHz

Ryzen 9 9900X3D: Balance of Power and Efficiency
For those who don’t quite need the absolute top-end, the Ryzen 9 9900X3D offers 12 cores and 24 threads, making it a formidable choice for high-performance gaming and productivity. With a 4.1 GHz base clock and up to 5.5 GHz boost, it’s no slouch in speed. Plus, it shares the same 3D V-Cache architecture, with 96MB L3 cache per CCD for a total of 192MB, bringing its total cache size to 204MB.
This CPU is tailored for gamers who want flagship-like performance but with a slightly lower power draw. Its 120W TDP makes it a bit easier to cool compared to the 9950X3D, while still providing plenty of horsepower for demanding workloads and modern gaming at ultra settings.

Second-Gen 3D V-Cache: What Makes It Better?
The first generation of AMD’s 3D V-Cache was already a game-changer, but there were limitations—mainly that only one CCD received the extra cache, creating a disparity in performance depending on where threads were scheduled. With the new architecture, AMD has eliminated that bottleneck by adding 3D V-Cache to both CCDs. This ensures more consistent performance and better utilization of all cores, whether you’re gaming, rendering, or multitasking.
Additionally, the second-gen implementation brings lower latency and higher bandwidth between the cache and cores, further improving workloads that benefit from large, fast cache pools—think high-frame-rate gaming, video editing, 3D rendering, and simulation workloads.
How Do They Stack Up Against the Competition?
AMD’s Ryzen 9 9950X3D and 9900X3D go head-to-head with Intel’s latest Core Ultra series. Early reviews and benchmarks point to AMD reclaiming the gaming crown with these chips. The 9950X3D often leads in gaming scenarios, while Intel still holds ground in certain productivity applications that leverage higher clock speeds on fewer cores.
However, for pure gaming, the combination of Zen 5 cores and massive 3D V-Cache makes AMD’s new X3D chips the better choice, especially for titles where cache size directly impacts frame rates and frame-time consistency.
Pricing and Availability
Both CPUs launched on March 12, 2025. The Ryzen 9 9950X3D debuted at $699, and the Ryzen 9 9900X3D launched at $599. Availability has been solid so far, with most major retailers carrying stock. Expect demand to stay high as gamers and enthusiasts look to upgrade their rigs with these cutting-edge chips.
Final Thoughts: AMD Doubles Down on Gaming Leadership
With the Ryzen 9 9950X3D and 9900X3D, AMD has taken everything that made their first 3D V-Cache processors a hit and made it better. Doubling the cache across both CCDs, improving latency, and maximizing Zen 5’s efficiency puts these CPUs at the top of many gamers’ and creators’ wish lists.
