x86, the mainstream instruction set architecture for PC CPUs, originated from the Intel 8086 processor and has been in use for 46 years. Technology blog Hackaday claims that x86 will be extinct in the ...

Single-instruction, multiple-data (SIMD) instructions that can process multiple data with one instruction greatly contribute to the speedup of CPU operation. However, since SIMD instructions require a ...

Security researchers have found new a new way to bypass existing hardware-based defenses for speculative execution in modern computer processors from Intel, AMD, and Arm. Today, the three CPU ...

Researchers at IBM and VU Amsterdam have developed a new attack that exploits speculative execution mechanisms in modern computer processors to bypass checks in operating systems against what are ...

There is a certain benefit to being an early adopter. If you were around when Unix or MSDOS had a handful of commands, it wasn’t hard to learn. Then you learn new things as they come along. If you ...

Intel has fixed a high-severity CPU vulnerability in its modern desktop, server, mobile, and embedded CPUs, including the latest Alder Lake, Raptor Lake, and Sapphire Rapids microarchitectures.

Some microprocessors from Intel and AMD are vulnerable to a newly discovered speculative execution attack that can covertly leak password data and other sensitive material, sending both chipmakers ...
