AMD claim its chips are immune to the MDS vulnerabilities plaguing Intel's CPUs

Microarchitectural Data Sampling (MDS) vulnerabilities have emerged as the latest flaw in Intel chips, following the infamous Spectre and Meltdown attacks. The chipmaker immediately resolved the MDS attacks that were able to extract data from the latest Intel CPUs through a series of patches.

The new patch may have solved the MDS issue but has dramatically impacted performance, especially multi-threaded performance. However, Intel’s woes are about to continue with leading rival AMD claiming that its chips are immune to MDS attacks due to built-in hardware protection checks.

According to Linux-specialist site Phoronix, the new patches that resolved the MDS flaw in Intel chips significantly impacted performance. Machines powered by Intel CPUs displayed a 16-per cent performance drop with hyper-threading enabled and new updates installed, while AMD chips remained largely unaffected with a meagre 3-per cent drop in performance.

But Intel’s problems don’t end there; Apple and Google have advised users to completely disable hyper-threading, stating that it is the only way to secure the Intel-powered machine’s from MDS attacks. While its highly doubtful Chromebook users will ever have to worry about hyper-threading; MacBook owners will suffer as disabling this feature could drop performance by 40 to 50 percent depending on the application.
