A new side-channel vulnerability has been discovered called PortSmash that uses a timing attack that to steal information from other processes running in the same CPU core with SMT/hyper-threading ...

ZombieLoad is similar to previous “side channel” attacks, which trick Intel processors into coughing up potentially sensitive information that otherwise would be kept private by the CPU. The exploit ...

Has Intel's Hyper-Threading support become a fundamental security problem? Theo de Raadt, founder of OpenBSD, argues that it has. Share on Facebook (opens in a new window) Share on X (opens in a new ...

A bunch of Intel 15 th-gen specs have just leaked online, not only confirming that Intel is dropping DDR4 support from its forthcoming CPUs, but possibly also ditching Hyper-Threading. Details of a ...

The OpenBSD project announced today plans to disable support for Intel CPU hyper-threading due to security concerns regarding the theoretical threat of more "Spectre-class bugs." Hyper-threading (HT) ...

Intel has shipped Hyper-Threading CPUs for well over a decade, even subtracting the Core 2 era when the technology wasn't used. For most of that time, Hyper-Threading has been a technology that 'just ...

Intel and its partners have been busy mitigating Spectre and Meltdown, which are two types of speculative side-channel CPU attacks that, if exploited, could potentially expose a user's sensitive data.

Just how many CPU cores do you need for PC gaming? The conventional wisdom for the last few years has been four or even two cores—if you have Hyper-Threading. That convention got upended with DirectX ...

Most of Intel's microprocessor chips have a feature the company calls "hyper-threading." The technology improves performance in complex software environments by more efficiently juggling multiple ...
