Immediately I learn a brand new article on Anandtech, discussing the Bulldozer architecture intimately , specializing in the place it performs nicely, and extra importantly, the place it doesn’t, and why. So, to conclude, the story of multithreading efficiency just isn’t so simple as simply looking on the variety of cores. Nevertheless, since AMD and Intel have very completely different microarchitectures, the core-count turns into a quite meaningless measure of performance.
Applications that use these kinds of threads are nonetheless seen as ‘single-threaded’ by most individuals, because the work is still principally completed by one thread, while every other threads are principally waiting for an occasion to happen, waking up only to course of the occasion, and then going back to sleep once more.
Before studying your article I did not know a lot about HT and thought that one process merely cannot have more that 50% bodily core clocks … Read More
