GoKawiilAMD has just launched six new Ryzen PRO series CPUs as part of its Ryzen 9000 family, bringing 3D V-Cache for the first time to this lineup, along with unlocking higher TDPs. The Ryzen PRO series is intended for workstation users who prioritize security and stability, even though they otherwise use identical silicon to mainstream desktop parts. The new CPUs range from 6 cores all the way up to 16 cores, so let's break them all down.
At the very top, we have the flagship Ryzen 9 PRO 9965X3D rocking 16x Zen 5 cores that can boost up to 5.5 GHz. It features 128MB of total L3 cache — either 8-core CCD already has the standard 32MB of L3 cache, but one of the clusters gets another 64MB of X3D stacked underneath. The CPU has a 170W TDP, which is the same as the 9950X3D it's based on, marking the first time a Ryzen PRO CPU has broken the 65W power limit.
Then there's the Ryzen 9 PRO 9965; basically the same CPU but just without the extra cache. It also features 16x Zen 5 cores with a 5.4 GHz boost clock and a 170W TDP. The L3 cache is limited to 64MB since it has no 3D V-Cache. Moreover, the Ryzen 7 PRO 9955 brings 12x Zen 5 cores with maximum speeds of 5.4 GHz and a 120W TDP, once again rocking just 64MB of L3 cache.

The Ryzen 7 PRO 99755X3D is the other X3D-branded chip in this lineup, housing 8x Zen 5 cores that can clock up to 5.2 GHz on a TDP of 120W. This chip has a 92MB L3 cache pool since there's only one 8-core CCD to stack the 64MB of 3D V-Cache under. You can also get the same CPU with just 32MB of L3 in the form of the Ryzen 7 PRO 9755, featuring otherwise identical specs to its X3D counterpart.
Lastly, the Ryzen 5 PRO 9655 enters the battle as a true midrange offering, sporting 6x Zen 5 cores with a 5.4 GHz boost clock but still a 120W TDP. That makes it quite unique from the other 6-core offering, the Ryzen 5 PRO 96455, which is limited to just 65W. For a while, all Ryzen PRO SKUs were restricted to that number to maximize efficiency, but it looks like AMD is changing gears to allow even relatively budget parts to consume more power. The Ryzen 5 Pro 9655 has 32MB of L3 cache as well.
That wraps up all the new SKUs, expanding the Ryzen 9000 PRO family to accommodate every tier of managed or workstation computing. Now, keep in mind that these CPUs aren't available for sale via regular retail channels. Instead, you'll find these at OEMs, such as Lenovo, which is already working to launch its ThinkStation P4 in Q3 2026. That's about all the details we have on availability, while pricing is never disclosed formally for PRO series SKUs anyway.
