Know-how is the energy that drives our lives. On this age of multitasking and multi-threading, it is quite common for a single course of to make use of multiple threads. Which is why there are so many myths… The MHz myth and the multi-core myth method the issue of performance from opposite angles, they usually each fail equally laborious at indicating total performance.
In my case, I at all times go for the i7. For those who had been to calculate the raw numbers, I am certain the i5 would give more efficiency for the buck on common… However I gladly pay the small additional premium to get that litle increase from HT when I require it.
On a core i3 it’s a different story: you only have 2 cores, and with HT you may run four threads, which will convey the CPU performance close to that of a daily four-core i5 in most video games. An eight-core machine will still get sluggish once you saturate it with realtime-priority threads.
Which would make sense, since this would still allow the host to dynamically allocate cores, and do correct load balancing. A workstation to fulfill all these requirements, two socket + multi-core + two GPU + AVX512, means a lot of money to spend. When evaluating CPUs with the identical microarchitecture, a CPU (on the same clockspeed) with extra cores will typically do higher in multithreaded workloads.
Particularly, not all threads shall be operating at all times. So having eight cores to assign threads to means one eighth the context switches for the cores. An i5 and i7 each have four cores, so at the similar clockspeed, HyperThreading will make the difference. If the cores have been quicker, it would simply imply some threads would be ready longer.
