A security researcher has created a tool to allow the extraction and analysis of AMD’s Platform Security Processor firmware.
There’s a clear winner when AMD and Intel go head to head in performance comparisons in Linux with all Spectre, Meltdown, Foreshadow, and other fixes applied. Intel loses a lot of performance in these comparisons.
Intel has disclosed a new set of speculative execution security issues that can leak data from CPUs under certain circumstances. How serious a problem they represent as a practical matter is still under debate.
It’s not clear if they can ever be resolved without jettisoning speculative execution, and the tremendous performance benefits it delivers.
Intel CPUs take a fairly heavy hit with the Linux 4.2 kernel, thanks to security measures to protect against Spectre / Meltdown attacks. The new changes impact a larger range of tests than were hit by the patches earlier this year.
Intel is announcing new Cascade Lake Advanced Performance servers, with up to 48 cores and an uncertain launch date.
When Spectre Variant 2 patches rolled out this year, some servers, particularly those with older Intel CPUs, saw performance declines. Google is working with MS to make sure we get that performance back.
Intel has announced its new 9th Generation CPUs, including the long-awaited 8-core, 5GHz, Core i9-9900K.
We now have updated information on the Intel Whiskey Lake and Amber Lake launches, first reported earlier this week.
Intel has backed off demands that users who apply a microcode fix for its Foreshadow security flaw in Linux never publish benchmarks of the results.
