Here’s Your First Look at a Delidded AMD Ryzen 7 9800X3D CPU With Next-Gen 3D V-Cache Tech

wccftech.com:

AMD's Ryzen 7 9800X3D is shaping up to be a one-of-a-kind CPU for the gaming segment & we have the first look at the delidded chip, which features next-gen 3D V-cache technology.

AMD Ryzen 7 9800X3D Delidded CPU Shows No 3D V-Cache Traces on The Front of the CCD Confirming Updated X3D Tech

The AMD Ryzen 7 9800X3D CPU will be the successor to the Ryzen 7 7800X3D. The latter has been a huge success on the AM5 platform, just like the Ryzen 7 5800X3D was on the AM4 platform. While the chip is expected for a formal launch on the 7th of November as teased by the red team, we have obtained the first delidded pictures of the Ryzen 7 9800X3D CPU from our sources, confirming one big change.

At first glance, the delidded AMD Ryzen 7 9800X3D CPU will look like a standard Ryzen 9000 chip with a single CCD and IO die. You can see that the chip has several power caps on the outskirts & the CCD/IOD are positioned in the same manner as the Ryzen 9000 CPUs based on the Zen 5 core architecture. But there's one big change that's evident by looking at the CCD.

On previous iterations of 3D V-Cache offerings such as the Ryzen 5000X3D and Ryzen 7000X3D CPUs, you can see traces of the 3D V-Cache stack when light is reflected at a certain angle. That is not the case with the Ryzen 7 9800X3D, which has no such traces on the top of the CCD. This is because the Ryzen 9000X3D CPUs employ the 3D V-Cache stack underneath the Zen 5 CCD and that's the next-generation technology that is expected to debut with the new 3D V-Cache chips.

This confirms a recent post by HXL (@9550pro) who also stated a similar 3D V-Cache stacking hierarchy for the new chips. The most interesting thing about this new stacking design is that it opens the room for another 3D V-Cache stack to be employed over the Zen 5 CCD, so you could theoretically get two stacks. This would make for a true stacked chiplet
