Samsung Foundry plans to disclose more details about its upcoming SF4X process technology that will target high-performance computing (HPC) applications, such as datacenter CPUs and GPUs, at the 2023 Symposium on VLSI Technology and Circuits. The new fabrication technology — previously known as 4HPC (4nm-class, high-performance computing) will not only enable higher clocks and efficiency, but will also support increased voltages for those who need maximum performance.
Samsung's new SF4X promises a performance increase of 10% while achieving a 23% reduction in power consumption. Although Samsung has not provided a specific reference point for these comparisons, it is likely that the chipmaker is comparing SF4X to its standard SF4 (4LPP). The performance gains and power savings are a result of a comprehensive reassessment and redesign of the transistor source and drain under likely high-stress conditions, further transistor-level design-technology co-optimization, and redesign of middle-of-line (MOL) circuitry.
