Nvidia says its GPU hardware is 'immune' to Meltdown and Spectre flaws

"All of our cloud services are affected by updates required to mitigate the Meltdown vulnerability", it said in an.

Nvidia has been in touch to clarify that its GPU hardware is not at risk from the Meltdown and Spectre vulnerabilities.

The company now says that while it thinks that GPZ Variant 2 is hard to exploit on its chips, it'll still work with its partners to release microcode updates and OS patches to mitigate the vulnerability.

As a bonus, here is a graph from Intel showing the performance hit that its security updates for Meltdown and Spectre will bring to various Intel processors.

Meltdown and Spectre have been discovered in computer chips in billions of computers, smartphone and tablets across the world.

In the letter Krzanich thanked Google Project Zero for revealing the issues in a responsible manner, and also pledged that the company would increase industry and academic research into security and improve disclosure of security issues. The downside of this would be that it would slow down applications considerably and cause inconsistent performance.

"The bottom line is that continued collaboration will create the fastest and most effective approaches to restoring customer confidence in the security of their data".

Mathews had initially told authorities he made Sherin stand outside because she wouldn't drink her milk, and she disappeared. According to the affidavit, Mathews also said "he knew coyotes had been seen in the alley where he left his daughter".

"In September, we began deploying solutions for both Variants 1 and 3 to the production infrastructure that underpins all Google products - from Cloud services to Gmail, Search and Drive - and more-refined solutions in October", Google writes.

Intel also lists benchmark scores with PCMark 10 as well as 3DMark Sky Diver which cover better content creation and game performance.

As work continues on short-term fixes, many experts agree the technology industry faces a wholesale reckoning of long-established practices that led to these vulnerabilities in the first place.

"The threat and the response to the three variants differ by microprocessor company, and AMD is not susceptible to all three variants".

Fortunately, Google has chose to share the details of Retpoline with the rest of the industry.

It adds, "With Retpoline, we didn't need to disable speculative execution or other hardware features". Devices using the 7th Gen Kaby Lake-H mobile processors will be around 7% slower, while the performance impact on systems with the 6th Gen Skylake-S platform is estimated to be around 8%.
