OnLogic Karbon 700: Passively-Cooled, Up To 8 Core / 16 Thread Industrial & Rugged PC
OnLogic (formerly known as Logic Supply until a recent rebranding) announced the Karbon 700 back in August as a durable Linux-friendly computer largely intended for industrial applications but nothing prevents the user from using it as a passively, well-built desktop PC either. OnLogic recently sent over the Karbon 700 and it's been working out very well even with passively cooling an Intel Xeon eight-core / sixteen-thread processor, 16GB of RAM, 512GB NVMe storage, and more.

The Firefox + Chrome Web Browser Performance Impact From Intel's JCC Erratum Microcode Update
With yesterday's overview and benchmarks of Intel's Jump Conditional Code Erratum one of the areas where the performance impact of the updated CPU microcode exceeding Intel's 0~4% guidance was on the web browser performance. Now with more time having passed, here are more web browser benchmarks on both Chrome and Firefox while comparing the new CPU microcode release for the JCC Erratum compared to the previous release. Simply moving to this new CPU microcode does represent a significant hit to the web browser performance.

The Gaming Performance Impact From The Intel JCC Erratum Microcode Update
This morning I provided a lengthy look at the performance impact of Intel's JCC Erratum around the CPU microcode update issued for Skylake through Cascade Lake for mitigating potentially unpredictable behavior when jump instructions cross cache lines.

Benchmarks Of JCC Erratum: A New Intel CPU Bug With Performance Implications On Skylake Through Cascade Lake
Intel is today making public the Jump Conditional Code (JCC) erratum. This is a bug involving the CPU's Decoded ICache where on Skylake and derived CPUs where unpredictable behavior could happen when jump instructions cross cache lines. Unfortunately addressing this error in software comes with a performance penalty but ultimately Intel engineers are working to offset that through a toolchain update. Here are the exclusive benchmarks out today of the JCC erratum performance impact as well as when trying to recover that performance through the updated GNU Assembler.
