  > "Samsung Foundry .. 4nm-class process technology,
  
  Lehet, hogy az SF4X ?
  
  """
  
  , Samsung Foundry is prepping its
  SF4X (4HPC, 4 nm-class high-performance computing)
  designed for performance-demanding applications like
  datacenter-oriented CPUs and GPUs.
  To address such chips, Samsung's SF4X offers a performance boost of 10% coupled with a 23% power reduction. Samsung doesn't explicitly specify what process node that comparison is being made against, but presumably, this is against their default SF4 (4LPP) fabrication technology. To achieve this, Samsung redesigned transistors' source and drain after reassessing their stresses (presumably under high loads), performed further transistor-level design-technology co-optimization (T-DTCO), and introduced a new middle-of-line (MOL) scheme.
  The new MOL enabled SF4X to offer a silicon-proven CPU minimum voltage (Vmin) of 60mV, a 10% decrease in the variation of off-state current (IDDQ), guaranteed high voltage (Vdd) operation at over 1V without performance degradation,
  and an improved SRAM process margin.
  Samsung's SF4X will be a rival for TSMC's N3P and N3X nodes, which are due in 2024 and 2025 respectively. Based on claim specificaitons alone, it is hard to tell which technology will offer the best combination of performance, power, transistor density, efficiency, and cost. That said, SF4X will be Samsung's first node in the recent years that was specifically architected with HPC in mind, which implies that Samsung has (or is expecting) enough customer demand to make it worth their time.
