AMD: Windows scheduler isn’t to blame for Ryzen performance problems

AMD claims it found no connection between the scheduler in Windows and Ryzen performance hits, but others in the community disagree.

Ryzen has proved its worth already and we’ve only just seen the company’s latest line of more advanced processors. AMD has done a stellar job in not only bringing the fight back to Intel and regaining some ground in the CPU market, but it did so while designing and launching a completely new platform. Regardless as to how you feel about AMD and its past products, that’s a commendable achievement.

It hasn’t been the smoothest of launches, but that is to be expected with a brand new platform. Manufacturing partners need to get accustomed to things with the new AM4 motherboards, and developers need to get everything optimized on the software side. Ryzen has performed well overall in benchmarks, but there have been a few reports of performance hits, which were addressed by AMD in a recent blog post.

Many have put it down to Microsoft’s OS and how Windows interacts with the new line of processors. Those critics believe that instead of Windows seeing and communicating with Ryzen CPUs as 2×4 CPU Complex (CCX) configurations, the OS is actually detecting a 1×8 setup and scheduling as though memory across both core sets is uniform. This is believed to be the cause of the minor performance blips that were reported.

Sean Spicer defends healthcare plan amid reports 24m could lose insurance

Press secretary rejects Congressional Budget Office’s coverage figures but embraces findings on deficit, saying CBO is ‘good at dollars, not as good at people’

The White House was forced to defend its healthcare plan on multiple fronts on Tuesday after a damning report found it would deprive millions of people of insurance, deepening divisions in the Republican party.

A nonpartisan Congressional Budget Office (CBO) study released on Monday predicted that by 2026, the number of people without insurance would increase by 24 million if House Republicans’ legislation to replace the 2010 Affordable Care Act (ACA) – also known as Obamacare – is adopted.

How Earth became a giant snowball 700 million years ago

Harvard scientists say they might finally have the answer to what caused the

Around 717 million years ago, the Earth froze over. The Sturtian glaciation, as this event is known, was no ordinary Ice Age but one so extreme that it caused the Earth to become a giant snowball for at least five million years. How it happened has been a mystery for the ages – till now. In a new study, Harvard scientists suggest that the answer might lie in the way volcanic eruptions caused the Earth’s temperatures to plummet.
