Some Alder Lake SoCs won’t come with performance cores

According to an update to a Linux storage that Intel made themselves, found by Japanese platform Coelacanth Dream, the Alder Lake-based Atom processors will change the craze and have up to eight e-cores and no p-cores.

In the last update, which has a partial boot log of an Alder Lake-N part, Intel defines the Atom processors as containing two quad-core sets of e-cores with 2 MB of L2 cache each and a shared L3 cache of an unrevealed size. They even have a 32 EU GPU, identical to the i5-12600.

These Atom processors will probably end up in SoCs for business applications and as embedded processors in OEM systems, like Chromebooks.

According to Intel, e-cores perform about the same as Skylake cores. In TechSpot’s in-game testing, we saw that claim to be slightly untruthful: in some titles, that was correct, but in most, they were much worse. Nevertheless, the difference wasn’t caused only by the e-cores’ worse throughput — it was primarily due to their inferior inter-core latency.

Though games are sensitive to latency, not all applications are. Intel’s claim about multi-threaded applications like Blender was roughly true. To draw a sudden decision, an octa-core e-core processor could be nicely fit to SoC and embedded applications shouldn’t be ignored.

In comparing an eight e-cores Atom processor with only two p-cores Celeron (although they do have four threads hyperthreading), the performance of Atom was not all that much worse, plus at least consume less power and take up far less space.
