Why can’t Intel’s 12th-gen CPUs go the bar examination? Blame the E-cores

Intel's 12th-generation Core CPUs use different types of CPU cores for different tasks. That hybrid architecture continues to cause problems for some software.

Earlier this week, some folks ready to take the bar examination obtained a message from ExamSoft, the corporate that makes the Examplify software program that many states use to manage the examination: PCs with Intel’s newest 12th-generation Core processors are “not at the moment supported” as a result of they have been “triggering Examplify’s computerized digital machine verify.” The corporate’s steered answer was that folks discover one other machine to take the take a look at with, a irritating and unhelpful “workaround” for anybody with a brand new pc.

As identified by The Verge, Examsoft’s system necessities web page for its software program offers no further element, merely reiterating that 12th-gen CPUs aren’t at the moment supported and that you simply aren’t allowed to run the Examplify software program inside a digital machine. But it surely’s not the primary time an issue like this has surfaced, and the wrongdoer is nearly definitely the hybrid CPU structure that Intel is utilizing in most 12th-gen chips.

In earlier generations, all the cores in a given Intel CPU have been similar to 1 one other: identical design, identical efficiency, identical options. Clock pace and energy utilization would ramp up and down primarily based on what the pc was doing at any given time, however the cores themselves have been all the identical and could possibly be handled that manner by the working system. In 12th-gen chips, CPUs include a mixture of fully totally different processor cores: giant, quick efficiency cores (or P-cores) deal with the heavy lifting, whereas smaller, low-power effectivity cores (or E-cores) deal with lighter duties. However as a result of working techniques and most apps are used to assuming that each one CPU cores in a given system are the identical, software program has wanted to be modified to inform the distinction between the 2.
