Will the patch for CPU vulnerability affect render speed vor Intel or AMD CPU?
Does anybody know, if the patch for CPU vulnerability affect render speed vor Intel or AMD CPU?
Intel also denied claims that performance of Intel-based computers would be significantly affected by Meltdown. One report had claimed the degradation could cause a slowdown of between 5% and 30% of typical performance. "Contrary to some reports, any performance impacts are workload-dependent, and, for the average computer user, should not be significant and will be mitigated over time," the company said.
Gruss said he was unsure about the potential impact on performance, telling Forbes it depended on many factors, from the processor architecture to the use case. He did agree with Intel, however, that regular computer users wouldn't be affected much by the slow down. But, he added, "unusual workloads" on older computers could be up to 50% slower."
It has to do with results of preemptive calculations, so processor having nothing else to do, doing things it expects it will be asked to do later. This will be switched off.
Not sure how much free time the processor has when rendering.
The benchmarks here, pre and post patch suggest no effect on render times
ok, that means the PC could be slower for other things while I am rendering?
Skating past you guys with my Ryzen 1600x. LOL!
Cool. Thank you. :-)
These "benchmarks" mean nothing, since they don't use the branch path system that is being turned off.
