• AMD Sampling Next-Gen Ryzen Desktop "Medusa Ridge," Sees Incremental IPC Upgrade, New cIOD

  AMD is reportedly sampling its next-generation Ryzen desktop processor powered by the "Zen 6" microarchitecture, codenamed "Medusa Ridge," to close industry partners, such as platform designers and OEMs, says Yuri Bubliy, aka 1usmus, author of the Hydra tuning software, and the now-retired DRAM Calculator for Ryzen. The processor sees AMD update both the CCDs and client I/O die, he says. AMD confirmed that it is building the "Zen 6" CCD on the TSMC N2 (2 nm) node, which entered risk production earlier this year. The node is expected to be ready for mass-production of 2 nm chips later this year. The 2 nm node presents a significant jump in transistor densities from the current TSMC N4P node on which AMD builds its 8-core "Zen 5" CCD, which 1usmus and other sources say, that AMD will use to increase CPU core counts per CCD.
  
  Sources point to the possibility of AMD increasing core counts per CCD to 12, and giving the CCD 48 MB of L3 cache. At this point we don't know if all 12 cores will be arranged in a single CCX with a monolithic slab of 48 MB L3 cache, or if there's a dual-CCX layout with 6 cores per CCX sharing 24 MB of L3 cache, each. The other big upgrade with "Medusa Ridge" is its client I/O die (cIOD). AMD is expected to build its new generation cIOD on a newer EUV node such as 5 nm N5 or 4 nm N4P, a significant upgrade from the current 6 nm N6. 1usmus says that the biggest reason for AMD to update its cIOD is the memory controller architecture. AMD is expected to give "Medusa Point" a new dual memory controller architecture. There are still two DDR5 channels per socket, but this is redesigned for increased memory speeds, letting AMD catch up with Intel in this area. As for the CPU frequency boosting technologies, such as PBO and Curve Optimizer, there are no updates expected, and 1usmus concludes that it Hydra support should be straightforward.

  

• (PR) Unknown Worlds Confirms Subnautica 2 Delay to 2026, Releases New Gameplay Trailer

  As you know, we believe deeply in the open development process at Unknown Worlds. All of our games, from Natural Selection to Subnautica, have been fully committed to that process. The first phase of open development on Subnautica 2 was a series of playtests that recently happened behind the scenes with our community. We got some great feedback about Subnautica 2 during those playtests. The community was responding well to the environment, creatures, and story, and felt positive about the general direction of the game. It gave us a great indication that we're swimming in the right direction.
  
  It also provided some insight that there are a few areas where we needed to improve before launching the first version of Subnautica 2 to the world. Our community is at the heart of how we develop, so we want to give ourselves a little extra time to respond to more of that feedback before releasing the game into Early Access. With that in mind, we've made the decision to delay Subnautica 2's Early Access release to 2026.
