Raspberry Pi 4 Thermal Performance Is Improving With New Firmware

Sun, 12/01/2019 - 00:08
When the Raspberry Pi 4 launched earlier this year it was quickly realized active cooling was almost required if wanting to run the quad-core Cortex-A72 SoC at full performance without thermal throttling. Fortunately, the latest Raspberry Pi 4 firmware has improved the thermal/power behavior to lessen the need for extra cooling although it's still recommended for achieving peak performance potential out of this popular low-cost ARM SBC...

Threadripper 3970X Performing Better On Windows Relative To Linux - Thanks To Microsoft Or Zen 2?

Sat, 11/30/2019 - 22:37
With the AMD Ryzen Threadripper 3970X benchmarks on Windows 10 and Linux, Ubuntu 19.10 and other common distributions were just ~2% faster than the Microsoft OS and Clear Linux was just ~10% faster, based on 80+ benchmarks carried out. Those margins are much closer than we have seen with past iterations of Threadripper, but is that due to the Zen 2 microarchitecture and the improved topology of the new Threadripper CPUs or due to Microsoft's scheduler changes and other software improvements made in Windows 10 November 2019 Update? Here are some benchmarks...
