Spectre and Meltdown may force long term changes in CPU design

REUTERS/Choi Dae-woongSecurity flaws Meltdown and Spectre affect processors made in the last 20 years. But Apple claimed the slowdown will be negligible - there's "no measurable reduction in performance" on the operating systems and only as much as a 2.5% decrease in speed on the Safari web browser. We expect to make updates available for our previous generation products over the coming weeks. Windows 7 and 8 are installed on 51% of computers, according to NetMarketShare.

CHIPMAKER Intel has promised to be more "transparent" about the whole Meltdown/Spectre hoo-hah following complaints that patches causing reboot borkage.

The first issue, dubbed Meltdown, is a vulnerability that would allow hackers to access the central processing unit (CPU) on a computer or cloud computing platform and steal passwords and other sensitive information. The company noted that it doesn't believe its software is vulnerable to Meltdown at this time.

Microsoft said it is blocking security updates to Windows PCs for Spectre and Meltdown CPU flaws due to compatibility issue with some versions of Antivirus software. "We are passionate about continuing to work with our partners in the industry to provide the best possible experience for our customers". There are billions of devices out there. As per SYSmark benchmark, the overall performance impact will be 6-4% for Office Productivity, Data/Financial Analysis, and Media Creation. On the Radeon side of things, AMD does not use speculative execution and as a result, no GPU patches will be necessary.

The meat of Krzanich's letter, however, relates to Intel's "commitments to our customers" with 3 clear pledges.

Microsoft has released a statement on the ongoing security issues that affect most modern desktop and mobile processors from both AMD and Intel and it has some users concerned.

Updates were recently released for Windows 10 machines which will update automatically. It issued an update on Jan. 4 that addresses the problem and recommended that businesses update their products immediately. "Windows operating system updates to devices that have impacted AMD processors".

How is Spanning protecting customer data and what steps are being taken at Spanning right now? So, out of an abundance of caution AMD will be making optional micro code updates available to further contain the threat. That's right - they think these 10 stocks are even better buys.
