There is a 50% difference in the performance of the two cores in Alder Lake

Intel Alder Lake processor is the first x86 processor with a hybrid architecture to be deployed on multiple platforms, naturally, it has attracted many people’s attention, especially how the performance of the two different architectures in the processor is what many people want to know. Intel had a simple answer to this at the Hot Chips 33 conference.

Traditional processors have a linear relationship between single-thread performance and multi-thread performance. The stronger the single-thread performance of the core architecture, the stronger the multi-thread performance.

But it’s different in a mixed architecture processor like Alder Lake. The purpose of the P-Core performance core is to improve the single-threaded performance of the processor. The purpose of the E-Core performance core is to improve multithreading performance with lower power consumption. According to Intel’s schematic diagram, four performance cores add up to the size of one performance core.

The single-thread performance of the performance core is 50% higher than the performance core under the same power consumption, and the actual situation is that the frequency and power consumption of the performance core will be much higher than the performance core, so the gap will be even greater, of course, the performance cores themselves are not bad, don’t think of them as small cores of ARM processors.
