TSMC Reveals 2nm Node: 30% More Performance by 2025

TSMC’s 3nm Node: No SRAM Scaling Implies Extra Costly CPUs and GPUs

Posted on

With regards to brand-new fabrication nodes, we count on them to extend efficiency, lower down energy consumption, and improve transistor density. However whereas logic circuits have been scaling nicely with the current course of applied sciences, SRAM cells have been lagging behind and apparently nearly stopped scaling at TSMC’s 3nm-class manufacturing nodes. It is a main drawback for future CPUs, GPUs, and SoCs that can probably get costlier due to gradual SRAM cells space scaling.

SRAM Scaling Slows

When TSMC formally launched its N3 fabrication applied sciences earlier this yr, it stated that the brand new nodes would offer 1.6x and 1.7x enhancements in logic density when in comparison with its N5 (5nm-class) course of. What it didn’t reveal is that SRAM cells of the brand new applied sciences nearly don’t scale in comparison with N5, in line with WikiChip, which obtained info from a TSMC paper printed on the Worldwide Electron Gadgets Assembly (IEDM)
