AMD EPYC 2 Rome What We Know Will Change the Game
Between events at AMD Next Horizon event in San Francisco, I wanted to do a quick recap of the new AMD EPYC 2 “Rome†platform. There were a number of disclosures today, and we can now have a discussion on what the next-generation performance picture will look like. You can see our AMD EPYC 2 Rome at the Next Horizon Event coverage to learn more. The star of the show was the new AMD EPYC 2, here it

Myths Programmers Believe about CPU Caches
As a computer engineer who has spent half a decade working with caches at Intel and Sun, I’ve learnt a thing or two about cache-coherency. This was one of the hardest concepts to learn back in college – but once you’ve truly understood it, it gives you a great appreciation for system design principles. You might be wondering why you as a software developer should care about CPU cache-design. For o

Why Raspberry Pi isn't vulnerable to Spectre or Meltdown - Raspberry Pi
Over the last couple of days, there has been a lot of discussion about a pair of security vulnerabilities nicknamed Spectre and Meltdown. These affect all modern Intel processors, and (in the case of Spectre) many AMD processors and ARM cores. Spectre allows an attacker to bypass software checks to read data from arbitrary locations in the current address space; Meltdown allows an attacker to read
