CPU manufacturers must address issues that arise with processors already on the market, especially the errors that are discovered over time. To handle this, Intel has released a new version of ...

From a technical standpoint, everything a computer does involves reading, manipulating, and storing information through microcode instructions that move around 0’s and 1’s. Each operation performed by ...

When AMD finally issued patches for its critical microcode security hole on Monday, it said that the glitch 'could lead to the loss of Secure Encrypted Virtualization protection.' AMD on Monday issued ...

What just happened? AMD has confirmed a security vulnerability in some of its processors, which was inadvertently revealed through a beta BIOS update from Asus. The flaw, described as a "microcode ...

Historically speaking, even when it wasn't the absolute fastest option, Intel has always been 'competitive' with longtime rival AMD in terms of CPU gaming performance. That is actually still the case ...
