Fig. 3: Fundamental limit and extrapolated energy cost per operation for ideal serial and parallel computers.
From: Fundamental energy cost of finite-time parallelizable computing
Fundamental limits obtained for a = h (Planck constant; T = 1K) (solid lines) and extrapolated energy cost corresponding to a = 2.3kTs (Xeon Phi; T = 330 K) (dashed lines) for ideal serial, Eq. (3) (blue), and parallel, Eq. (4) (orange), computers. The measured value for a Xeon Phi processor is represented by a black X. For reference, an energy cost of 1 J/operation is shown as a dash-dotted line. Parameters are \({{{{{{{\mathcal{T}}}}}}}}=1\) s and b = 1.
