NVIDIA Issues GPU Driver Security Updates in Response to 'Spectre' Security Flaw

"For context, on newer CPUs such as on Skylake and beyond, Intel has refined the instructions used to disable branch speculation to be more specific to indirect branches, reducing the overall performance penalty of the Spectre mitigation".

Their statements sow further confusion for businesses struggling to decide how to respond to the revelation of the Meltdown and Spectre security flaws, following mixed messages from different chipmakers about how widespread or serious the problem is. The company says those running Windows 10 on PCs with Haswell and older chips will see more significant slowdowns in benchmarks and that "some users" will notice the loss in speed. On Tuesday, it said that computer systems from 2005 or older with an Intel CPU chip and running Windows 7 or 8 may indeed experience a decrease in system performance.

It's not just your processor and operating system that are affected by the Meltdown and Spectre memory vulnerabilities - your graphics card is, too. "We are working quickly with these customers to understand, diagnose, and address this reboot issue". Spectre and Meltdown security patches will also impact the performance of Macs, iPhones, iPads and other Apple devices.

Intel, whose processors act as the brains in most PCs, said on Thursday that any slowdown in PC performance from the software patches needed to protect machines "should not be significant".

"For small to medium-sized installations and desktop usage I do not believe the performance to be an issue for most workloads".

Intel adds that the reduction in performance that was predicted as a result of the patches hasn't materialised, or is less than anticipated.

Advanced Micro Devices Inc and Softbank's ARM Holdings have said their central processing units are potentially exposed to Spectre.

And the servers are likely to feel the impact the worse.

Recent reports suggest that computers - personal, business, and cellular alike - are susceptible to two newly discovered major security flaws. Meltdown allows hackers to bypass the hardware barrier, allowing them to read a computer's passwords and other sensitive information. "We are patching the CPU vulnerability the same way that Amazon, the same way that SAP, the same way that Microsoft, etc are patching, because we have software as well".
