The Snapdragon 8 Gen 4 is Qualcomm’s first SoC entrant that will ditch ARM’s core designs and switch to custom Oryon cores codenamed Phoenix. Though the new chipset will arrive with many expectations on its shoulders, the latest word on the rumour mill is that the San Diego company appears to be running into power consumption problems with its new silicon. Thankfully, with the Snapdragon 8 Gen 3 unveiling happening before, Qualcomm has plenty of time to tackle these setbacks.
Snapdragon 8 Gen 4 is also said to deliver ‘decent’ performance, but no comparison has been made in the latest rumour
Revegnus did not provide the performance figures, but he does mention that the Snapdragon 8 Gen 4 is suffering from ‘serious’ power consumption issues. Despite Qualcomm switching to TSMC’s N3E process next year, which is said to improve power efficiency over the Snapdragon 8 Gen 3’s N4P node, the Snapdragon 8 Gen 4’s rumoured problems have yet to be addressed.

From the looks of it, Qualcomm might want to match the performance of Apple’s A-series lineup. The Snapdragon 8 Gen 4 is said to be tested out with two version and six power efficiency cores, but a higher clock speed enabled on the performance cores can spike power consumption quickly.
In the case of Nuvia, unlike the 8cx Gen 4, it seems that the 8 Gen 4 provides decent performance, but there are serious issues with power consumption. https://t.co/mTffBT5bGy

Even with the A17 Pro, which is exclusively found in the iPhone 15 Pro and iPhone 15 Pro Max, despite mass produced on TSMC’s 3nm process, Apple still had to raise power consumption on the latest SoC so that it obtains suitable performance gains over its predecessor, the A16 Bionic.
At this stage, we cannot conclude if TSMC’s N3E process or Qualcomm’s desire to raise the performance target of the Snapdragon 8 Gen 4 are the culprits here, but with the Snapdragon 8 Gen 3 launch said to happen later this month, the focus will be placed on this year’s silicon. Even the Snapdragon 8cx Gen 4, which is also said to feature the same Oyron cores, Qualcomm is said to be running into undisclosed problems.
Fortunately, since the Snapdragon 8cx Gen 4 will power notebooks instead of smartphones, Qualcomm has a little flexibility on its hands in raising the power consumption figure. Still, on the Snapdragon 8 Gen 4, a delicate balance is necessary.
