AMD says reviving the Ryzen 7 5800X3D was 'very, very hard'

AMD has brought back the Ryzen 7 5800X3D to serve a DIY market still full of AM4 motherboards and DDR4 systems. David McAfee, VP of Ryzen and Radeon at AMD, notes many users are still gaming on chips like the Ryzen 5 2600X or 3700X and, as a drop-in replacement, will see "a massive, massive jump in gaming performance." Reviving the chip involved more than restarting an old manufacturing line.

The original 3D V-Cache stacking method was no longer in use at TSMC, so the company had to "re-engineer, re-qualify, and rebuild" the product to migrate it to a newer process. McAfee says those changes make practically zero difference to the relative performance versus the original dies and do not change how the Ryzen 9000-series stacks its 3D V-Cache.
