AMD’s Ryzen 7 9800X3D has been torn apart to reveal its next-generation 3D V-Cache stack which lays underneath the Zen 5 CCD.
Chip Teardown Reveals The 2nd Gen 3D V-Cache Stack On The AMD Ryzen 7 9800X3D CPU
The AMD Ryzen 7 9800X3D launches for retail today, but a brave individual went ahead and done a full chip tear down of his chip to unravel its 3D V-Cache mysteries. The user “万扯淡” on the social media platform, Weibo, posted a video in which he delids the Ryzen 7 9800X3D CPU but doesn’t stop there. He goes one step ahead and tears the whole CCD apart to see what’s underneath.
While delidding the AMD Ryzen 7 9800X3D CPU with a delid tool is a pretty easy thing to do, it looks like the individual didn’t have access to such a tool and instead resorted to a heat gun to melt away the solder under the IHS and then take it apart. Upon delidding the chip, we can see the CCD & the IO die, which are the only two chiplets used on this specific SKU. We have previously posted a delid shot of the Ryzen 7 9800X3D which looks remarkably similar to the 9700X which is to be expected.
Since you can’t see the 3D V-Cache stack or the CCD without removing the protective shield over the die, the user took a screw to rip open the CCD which first revealed the Zen 5 CCD layers. The CCD was further punctured through to reveal the shiny blue 3D V-Cache stack which lays under the CCD this time. The user compared it to an already dissected 7800X3D which has the shiny blue 3D V-Cache stack on top of the CCD.
