Most PCs will get slower because of the chip flaw fix

Upcoming CPU patches could cause performance issues

Upcoming CPU patches could cause performance issues

The full details of the patch were disclosed on the tech giant's official website, but they seem to remain determined to assure their fans that at least for their GPUs, Nvidia has managed to make their device invulnerable and immune to things like Meltdown and Spectre.

Responding to questions about its GPUs, AMD says Radeon architectures do not use speculative execution and therefore are not susceptible to the threats. After that, Intel will focus on releasing updates for older products based on requests and priorities of its customers. Then there was the question of the performance impacts from the security patches that were hurriedly being prepared. Intel has downplayed reports of a performance hit on patched systems, despite Microsoft benchmarks warning of a server and PC slowdown when the fixes are applied to some systems. The big issue for these vendors is how much code needs to be rewritten for applications that currently run on Intel chips.

Brian Krzanich on Thursday published an open letter addressing its partners and customers regarding the aftermath of the Meltdown and Spectre exploits publication. Intel also claims that Skylake s-platform suffers from a higher performance impact and the data shows it to be of approximately 8 percent as compared to 6 percent of Windows.

"This means the typical home and business PC user should not see significant slowdowns in common tasks such as reading email, writing a document or accessing digital photos", Intel said in its update.

"In particular, we want to thank the Google Project Zero team for practicing responsible disclosure, creating the opportunity for the industry to address these new issues in a coordinated fashion". Presumably, it would take too much work to fix operating systems that are supposed to be discontinued in a few years anyway.

He said that regaining customer trust is something everyone in the industry will be striving for, and that continued collaboration will be key to making it happen.

As well as triggering undesirable behaviour the Spectre patches are degrading machine performance, particularly for older processors.

AMD itself, however, has now started delivering a fix to PC and motherboard OEMs to push out to their clients. Systems using AMD Opteron, Athlon or Turion X2 Ultra CPUs should gain access to the patch once again next week.

Giving yourself "maximum flexibility" means it will be easier to respond to future flaw discoveries, Segars said.
