it sets the package against heat problems

Qualcomm has taken the bull by the horns to address the heating problems with its high-end chips. Thus, its latest SoC, Snapdragon 8+ Gen 1, is made by TSMC instead of Samsung, and it does not promise as much a significant performance gain as real improvements in energy efficiency.

We were expecting a Snadragon 8 Gen 1 Plus, we want a Snadragon 8+ Gen 1, this is the first surprise from the chef signed Qualcomm for its new ultra premium SoC for smartphones, presented along with Snapdragon 7 Gen 1.

In addition to these purely marketing considerations, what does this new chip have in store for us, which will definitely equip a good portion of the advanced smartphones in the second half (Xiaomi, OnePlus, Samsung, Vivo and Motorola would already be in the lineup)? The chip is slated for release in Q3 2022 to be exact.

Finally a correct temperature

The biggest concern with the Snapdragon 8 Gen 1 is that if you want to play too much on big arms, it tends to heat up a bit, giving performance or autonomy issues. Qualcomm has clearly identified the problem and is trying to raise the bar with its 8+ Gen 1.

Starting with his choice of founder. 8 Gen 1 was manufactured by Samsung, the Plus version is left to TSMC if the 4 nm engraving process is considered to be more efficient and less focused on heating.

In addition, if there is actually a pure speed gain of 10% for the CPU and GPU, what interests us above all, therefore, is the promises in terms of energy efficiency of this chip. In detail, the enhanced versions of the Kryo CPUs and Adreno GPUs should both offer a significant gain of 30% in this area. In total, the phone should have up to 15% total energy efficiency.

A concrete gain in autonomy

What does this mean specifically for us? Qualcomm expects a gain of 60 minutes of use of the phone in the game, which suggests better autonomy also for more traditional use: 80 minutes in streaming, 50 minutes on social networks and no less than 17 hours to listen to music.

As far as we understand, the modem, Snapdragon X65 has also been slightly improved compared to 8 Gen 1 to offer some calling benefits: 25 minutes of calling in 5G and exactly 5 and a half hours otherwise, without specifying whether it is about Wi-Fi calls or via the traditional network. Of course, the modem is still 5G compatible up to 10 Gb / s, but it is also capable of offering up to 3.6 Gb / s in Wi-Fi 6 and 6E.

The 3 GHz milestone passed

For fans of pure power, let’s still set the maximum frequency reached by the GPU: 3.2 GHz. Impossible not to read an answer on MediaTek’s Dimensity 9000, which offered a frequency above 3 GHz, thus stealing the crown of the most powerful chip from 8 Gen 1 and its 2,995 GHz. Let us be clear though, these demonstrations of power will not change your daily experience in any way. Better power management, on the other hand, could be a game-changer.

On the other elements that make up this SoC, we keep exactly the same team, logical for a Plus version. You will therefore find the 7th generation of the Hexagon NPU, which as a reminder offered a performance increase of 20% compared to the Snapdragon 888. There is also the Sensing Hub, this small chip, which in theory is able to permanently offer functionalities cheap energy, such as face recognition, or even the same ISP offering up to 3.2 gigapixels per second. second image processing or even 8K HDR video.
