Next Exynos and Snapdragon flagship SoCs to adopt ARM’s X1 high-performance core

Back in May, ARM announced the successor to the most powerful core used in this year’s flagship chipsets named Cortex-A78. This new core promises not only performance gains but significantly improved efficiency as well. Arguably a more interesting part of ARM’s announcement, however, was the ultra-powerful X1 core, which is rumored to power up tomorrow’s flagship processors.

According to a renowned leakster, the X1 core will be used in both – the Exynos and Snapdragon chipsets, so it’s safe to assume that one of the first devices to hit the market with the X1 core is the Samsung Galaxy S21 lineup.

The two chipsets will have the same core configuration – 1+3+4. We can then expect the single powerful core to be the X1, the three cores will be Cortex-A78 and the last four will most likely be Cortex-A55 unless ARM announces a successor to its small, efficient core.

The X1 core itself promises 30% and 23% higher peak performance than the Cortex-A77 and A78, respectively. This is why this core will most likely remain in a single, separate cluster due to its high power demand.
