It's suspicious how the bottom point on each of those curves is exactly 35W. Real-world power measurements don't line up that cleanly, so I wouldn't be surprised if what they're graphing on that axis (for the x86 processors) is merely the power limit they set the systems to throttle to, rather than a real measurement. That or they interpolated to produce those points.
- jeffbee 5y agoGod knows what their method is, but the numbers on here for the CPU I actually own are consistent with 1) the benchmark results I see, and 2) the package power reported by the PMU, within a reasonable approximation.
- kllrnohj 5y agoMost of the x86 CPUs support setting power limits, which the CPU does actually respect with a fair degree of accuracy. They probably did that & verified it lines up.
- wtallis 5y agoThat'll get you within 5W easily, but it's definitely not as precise as what that graph is depicting.
