Qualcomm Snapdragon 8 Gen 1 Plus: TSMC s 4nm efficiency gains fizzle out due to high power consumption of the Cortex-X2

Snapdragon 8 Gen 1

The Qualcomm Snapdragon 8 Gen 1 Plus reportedly has the same efficiency issues due to the Cortex X2 core's high power consumption. This could force Qualcomm to underclock the SoC a bit and possibly not achieve the targeted performance gains.

The poor results of Samsung LSI's 4nm node has prompted Qualcomm to turn to TSMC for its SoC's. The risk seems to have been worth it, as previous reports suggest that the yields mentioned were remarkably better for the Snapdragon 8 Gen 1 Plus. However, Qualcomm may not yet be aware that the SoC is consuming more power than previously thought.

A reliable whistleblower at South Korean tech forum Meeco has learned from sources that the Snapdragon 8 Gen 1 Plus' Cortex X2 core is quite a power hog, especially at higher clock speeds. So far, the high power consumption of Qualcomm chipsets has been attributed to Samsung's inferior manufacturing nodes. While the latter is true to an extent, ARM's design could also play a role in the Snapdragon 8 Gen 1's not-so-great performance.

Therefore, Qualcomm may be forced to underclock the Snapdragon 8 Gen 1's main Cortex-X2 core. That could mean that the difference in performance between the Plus and non-Plus variants of the Snapdragon 8 Gen 1 could be even more marginal.

Several rumors have speculated that Qualcomm will unveil the Snapdragon 8 Gen 1 Plus sometime in June 2022. Smartphones with this chip could hit the market about a month later. Several highly anticipated flagships are said to feature the chip, including the OnePlus 10 Ultra, Huawei Mate 50, Xiaomi MIX Fold 2 and Xiaomi 12 Ultra.
