Intel vs AMD Processor Security: Who Makes the Safest CPUs?
Intel vs AMD Processor Security: Who Makes the Safest CPUs?
https://www.tomshardware.com/features/intel-amd-most-secure-processors Published a few minutes ago today... (this is just the summary below). 1) Intel currently has 242 publicly disclosed vulnerabilities, while AMD has only 16. ThatĒs a 15:1 difference in AMDĒs favor. The gap is just too large to ignore. 2) Less than half of the speculative execution side-channel attacks disclosed for Intel since early 2018 seem to affect AMDĒs Ryzen and Epyc CPUs. ItĒs true that in some of the cases where the flaws were declared to affect IntelĒs CPUs, the researchers may not have looked primarily at AMDĒs CPUs. However, even then AMD confirmed that those bugs didnĒt affect its processors after carefully verifying how the vulnerabilities affected its own processors. It truly seems as if AMD designed the new Ryzen microarchitecture with better security in mind than IntelĒs essentially Nehalem-based microarchitectures have been. Why Nehalem-based? Because most of the speculative execution attacks affect IntelĒs CPUs since at least 2008 when the Nehalem microarchitecture came out. 3) With the release of the new Zen architecture, AMD also seems to have been one step ahead of Intel in terms of supporting new hardware encryption features. It remains to be seen if AMD will maintain this pace in regards to security, as Intel tries to fix all of the Spectre issues and improve its image with consumers, but at least for now, AMD seems to have the lead. Even ignoring all the various performance slowdowns the Spectre-related patches have caused for both old and new systems alike, AMDĒs processors seem like the safer and more secure platform to choose in the near and medium-term. |
