Now that the patches across various platforms for the recently discovered Spectre and Meltdown vulnerabilities have largely been deployed, Google has detailed how it managed to address these threats on its cloud services such as Gmail and Search before the public even knew about them.
Intel said the older the user's processor is, the bigger the performance hit.
In the meantime, Microsoft this week said it has "temporarily paused" patches for Windows customers running AMD processors after some users reported seeing the "blue screen of death" after the update was applied.
The problems affect PC and datacenter systems running the company's Broadwell and Haswell processors.
All eyes were on Krzanich at CES 2018 as he gave the show's opening keynote, just days after experts in Google found the flaw in the chips made by Intel. The Wall Street Journal is reporting it got its hands on a confidential memo issued by the company and shared with large companies and cloud providers not to install the patches.
After an effort that Sloss described as a "moonshot", Google engineers were able to devise a software fix for the Intel processor problem that didn't result in a slowdown, and that had no other significant side effects. However, nearly immediately, customers began experiencing issues with their systems rebooting unexpectedly.
It said it had no reason to believe the drivers were troubled by the second flaw, dubbed Meltdown.
Intel has been hit by both Spectre and Meltdown and shares in all three chipmakers have been pushed around by the issues.
"Operating systems and software are now having to do work that the chip previously performed at very high speed", said independent security analyst Graham Cluley.
