Reports suggest that AMD will debut its 16-core and 12-core Ryzen 9000X3D CPUs in late March, coinciding with the launch of its Radeon RX 9000 series graphics cards. Citing internal sources, French hardware news website CowCotLand claims that the Ryzen 9 9950X3D and Ryzen 9 9900X3D are planned for release by the end of Q1, aligning with AMD's provided release timeframe.
AMD revealed its high-core count Ryzen 9000X3D offerings at CES, boasting a 20% performance bump in gaming against Intel's Core Ultra 200S (Arrow Lake) processors. There is no difference in the total cache size versus the last generation, as the chipmaker will continue offering the 3D V-Cache on a single CCD. However, AMD's 2nd-generation V-Cache technology, which has the SRAM chiplet beneath the CCD, allows these chips to have a higher thermal headroom with a Tjmax of 95 degrees Celsius. This enables higher boost clocks, as seen with the Ryzen 7 9800X3D. The Ryzen 9 7950X3D's V-Cache equipped CCD suffered a hefty 500 MHz frequency penalty compared to the CCD without the X3D cache, which should be resolved with the changes to the stacking structure.
