Qualcomm announced the Snapdragon 8+ Gen 1 Mobile Platform on May 20, 2022—not a product literally named “Snapdragon 8 Gen 1” with a new factory. The mid-cycle refresh moved production of the design from Samsung Foundry’s 4nm process to TSMC’s 4nm process, raised peak CPU speed to 3.2 GHz, and targeted a better performance-per-watt balance.
Qualcomm claimed up to 10% higher CPU performance, a 10% higher GPU clock, 30% lower GPU power consumption and 30% improved CPU power efficiency versus Snapdragon 8 Gen 1. In actual phones, the improvement was substantial but depended on cooling, firmware, display settings, battery condition and performance modes.

What Qualcomm actually announced
The announcement was a premium-platform refresh scheduled to reach commercial devices in the third quarter of 2022. Qualcomm kept the broad architecture and connectivity platform of the Snapdragon 8 Gen 1, but combined a new manufacturing source with higher operating targets and revised power behavior. The company emphasized gaming, artificial intelligence, cameras and battery improvements in its launch announcement: Qualcomm’s May 2022 announcement.

Qualcomm’s product page notes that manufacturers determine the final implementation and that the platform can be offered with different CPU-speed configurations: Snapdragon 8+ Gen 1 specifications.
Why the Samsung-to-TSMC move mattered
“4nm” is a generation label, not a universal technical standard. Samsung’s and TSMC’s processes have different electrical characteristics, libraries, design rules and manufacturing behavior. Moving this particular design to TSMC gave Qualcomm more power and thermal headroom, according to technical coverage from Ars Technica and AnandTech.
That headroom could be used in two ways: reaching a higher clock at a similar power level, or delivering similar performance with less power and heat. The result was not simply an overclock. The foundry transition, clock changes and platform tuning worked together. Available evidence does not justify assigning a precise percentage of the improvement to the factory alone.

Compared with Snapdragon 8 Gen 1, Qualcomm reported the following internal comparisons:
- Up to 10% higher CPU performance.
- 10% higher GPU clock speed.
- 30% lower GPU power consumption.
- 30% improved CPU power efficiency.
- More than 80 additional minutes of video streaming.
- More than 50 additional minutes of web browsing.
These figures describe Qualcomm’s controlled tests, not a guaranteed result for every retail phone. A 30% efficiency improvement does not mean 30% longer battery life: screen brightness, refresh rate, modem use, battery capacity, software, camera activity and thermal limits all contribute to a phone’s total consumption. Qualcomm’s comparison figures are documented in its Snapdragon 8+ Gen 1 product brief.
What testing and real phones showed
Independent testing generally found higher peak CPU performance, better efficiency and stronger sustained behavior than many Snapdragon 8 Gen 1 phones. The size of the gain varied by test method and handset. AnandTech cautioned that GPU results could look different when measuring a short peak run versus performance after several minutes of sustained load. Android Authority’s comparisons likewise found meaningful gains without making heat and power concerns disappear: benchmark analysis and commercial-phone comparison.
Peak benchmark speed, sustained gaming performance, average power draw, surface temperature, battery endurance and post-throttling consistency are different measurements. A large phone with a vapor chamber may win a short test, while a compact model may deliver better everyday endurance through more conservative software tuning.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Why the handset still matters
- Vapor-chamber size and thermal interface materials determine how quickly heat leaves the chip.
- Chassis dimensions and ambient temperature affect sustained performance.
- Firmware governors and gaming modes decide whether the phone favors speed, noise or temperature.
- A high-refresh, high-resolution display and active 5G modem can consume more power independently of the SoC.
- Battery age changes results substantially in used phones.
ASUS paired the Zenfone 9 with a 4,300 mAh battery, 30W charging and a redesigned cooling system, illustrating why the surrounding hardware remained part of the story: ASUS Zenfone 9 specifications.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Did it solve the Snapdragon 8 Gen 1 heat problem?
It improved the situation; it did not make heat irrelevant. The 8+ Gen 1 generally reduced the efficiency penalty seen in many first-generation 8 Gen 1 phones, but high-performance ARM cores still draw substantial power at elevated clocks. Gaming-oriented devices may run aggressively, while small phones have less thermal mass and less room for cooling hardware. The defensible conclusion is that the TSMC version offered more usable headroom, not that TSMC “fixed” every phone.
Phones that used Snapdragon 8+ Gen 1
Examples include the ASUS Zenfone 9, ASUS ROG Phone 6 series, OnePlus 10T, Xiaomi 12S series, Motorola Edge 30 Ultra and selected models from vivo, iQOO, nubia and Honor. Samsung used the platform globally in the Galaxy Z Fold4 and Galaxy Z Flip4, as Qualcomm confirmed: Qualcomm’s Galaxy Z announcement.
Availability and processors varied by market. Never assume that every regional version of a phone has the same chipset; verify the exact model number and carrier bands.
Should you buy a Snapdragon 8+ Gen 1 phone?
For a discounted, used or refurbished phone, the 8+ Gen 1 is normally preferable to the 8 Gen 1 when price, condition and support are comparable. It is still a 2022 flagship platform and was later superseded by Snapdragon 8 Gen 2 and newer generations, so the chipset name alone should not determine the purchase.
- Identify the exact model and region. Check the processor variant, 5G bands and market-specific software.
- Inspect battery health. A worn battery can erase much of the platform’s efficiency advantage.
- Check cooling and sustained tests. This matters more for gaming than a short benchmark score.
- Review display settings. Resolution and refresh rate materially affect endurance.
- Confirm update support. A 2022 phone may have fewer major Android updates remaining.
- Compare the price with Snapdragon 8 Gen 2 or later phones. A newer device may offer longer support and better efficiency even if its peak specification looks similar.
Bottom line
Snapdragon 8+ Gen 1 was a meaningful mid-cycle correction: Qualcomm moved production of the design from Samsung’s 4nm process to TSMC’s 4nm process, raised clocks and delivered a better performance-per-watt balance. It was usually faster and more consistent than Snapdragon 8 Gen 1 phones, but the final experience still depended on the phone’s cooling system, software, screen, battery and regional configuration.
