Hyperthreading's utility in probing caches has been documented since at least 2005. The cache probing techniques that are used when exploiting Spectre (or Meltdown) are all well-known, and using them ...

A new security report indicates issues with Hyper-Threading can leak cryptographic information in certain cases, but evidence points against this being a Spectre or Meltdown-class failure. Share on ...

At first, we had single core CPUs. These CPUs were clocked at a certain speed and could deliver performance at that particular speed. Then came the age of CPUs with multiple cores. Here, every ...

Things are looking increasingly desperate for Intel on the processor front. With upstart AMD set to announce the world's first 16-core, 32-thread gaming processor tomorrow - the Ryzen 9 3950X - ...
