Google’s Tensor G4 SoC to Adopt FOWLP Technology to Improve Heat Management, Power Efficiency: Report

Google Pixel 8 and Pixel 8 Pro were launched in October last year with a Tensor G3 chipset and several AI-based features. A few short months after their release, we are seeing multiple leaks about the next-generation Pixel phones on the Web. Google’s next-generation SoC — Tensor G4 — is anticipated to power the Pixel 9 and Pixel 9 Pro. The chipset would be reportedly based on Samsung’s latest 4nm process and might offer improved power efficiency and heat management.

As per a report by Korean media outlet FNN, Google will apply Samsung Electronics’ foundry 4-nano microprocessing to the Tensor G4 chipset that will be installed in the upcoming Pixel 9 series. The Tensor G4 would reportedly use an advanced packing method called the FOWLP (Fan-out Wafer Level Packaging). This type of packaging is said to improve the heat generation of semiconductors and increase power efficiency and performance. This would offer notable improvements over last year’s Tensor G3 SoC.

Further, the report states that Samsung used the 4nm method in the Exynos 2400 chipsets of the Galaxy S24 and Galaxy S24+ models. The report claims that the handsets were well-received in the select markets they were launched.

The Tensor G4 SoC was earlier tipped to come with minor performance upgrades over the Tensor G3 SoC.

In India, the Pixel 8 starts at Rs. 75,999 for the 8GB RAM + 128GB storage model, while the Pixel 8 Pro starts at Rs. 1,06,999 for the 12GB RAM + 128GB storage model.

Google’s Pixel 8 and Pixel 8 Pro run on Android 14. The vanilla variant sports a 6.2-inch full-HD+ (1,080×2,400 pixels) OLED screen with a 120Hz refresh rate. Meanwhile, the Pixel 8 Pro has a 6.7-inch OLED display with Quad-HD (1,344×2,992 pixels) resolution and 120Hz refresh rate. They run on Google’s Tensor G3 chipset and the Titan M2 security chip.

The Pixel 8 has a dual rear camera unit, led by a 50-megapixel Samsung GN2 sensor, while the Pixel 8 Pro boasts a triple rear camera setup, including a 50-megapixel main sensor. Both models carry a 10.5-megapixel front camera. The Pixel 8 houses a 4,575mAh battery with support for 27W wired charging, whereas the Pixel 8 Pro is backed by a 5,050mAh battery with support for 30W wired charging.

Google Might Use Samsung’s FO-WLP to Make Tensor G3 Run Cooler Than the Tensor G2

Google Pixel 8 series — consisting of vanilla Pixel 8 and Pixel 8 Pro — is all set to go official on October 4 at the ‘Made by Google’ event. Google is expected to pack the next generation Tensor G3 SoC on the Pixel 8 lineup as an upgrade over the Tensor G2 SoC that powers the Pixel 7 series. The company has yet to delve into details about its in-house chip, but a new leak suggests that it would offer better thermal management features. The Tensor G3 might come with Samsung Foundry’s FO-WLP (Fan-out Wafer-level packaging) method. This is expected to reduce heat generation and increase the power efficiency of the Pixel 8 series.

Tipster Revegnus (@Tech_Reve) on X (formerly Twitter) suggests that the Tensor G3, which is slated to power the upcoming Pixel 8 series handsets, will be among the first Samsung Foundry’s smartphone chips to incorporate the FO-WLP packaging method. This method is expected to reduce heat generation and increase power efficiency for the Tensor G3 SoC. If this turns out to be true, it would address the overheating issues of the current Pixel phones.

The FO-WLP process has been used by Qualcomm and MediaTek and it might be a game changer for Google’s Pixel series of smartphones. The Tensor G3 single-chip system is expected to be more productive than the first and second-generation platforms. The Tensor G3 will reportedly include nine CPU cores with a 1+4+4 layout. Last year’s Tensor G2 had a 4+2+2 core layout.

The new CPU will reportedly have a single Cortex-X3 core running at 3.00GHz, four Cortex-A715 cores with a frequency of 2.45GHz, and four Cortex-A510 cores with a frequency of 2.15GHz. It could include an ARM Mali-G715 GPU with 10 cores and a frequency of 890MHz. Further, the Tensor G3 SoC is said to come with AV1 encode capabilities. This would allow Samsung Multi-Function Codec (MFC) to support 8K30 video decoding and encoding in H.264 and HEVC.

The launch of Pixel 8 and Pixel 8 Pro will take place at the Made by Google launch event on October 4 in New York at 10:00am local time (7:30 pm IST). Besides the smartphones, the event will also see the debut of Pixel Watch 2 and Pixel Buds Pro. The handsets are confirmed to be available for pre-order in India via Flipkart starting October 5.

Both Pixel 8 series smartphones are expected to ship with Android 14 and come with 120Hz refresh rate displays. The Pixel 8 Pro is expected to pack a 4,950mAh battery with 27W wired fast charging support. Meanwhile, the Pixel 8 could be backed by a 4,485mAh battery with 24W wired charging and 12W wireless charging support.


Google I/O 2023 saw the search giant repeatedly tell us that it cares about AI, alongside the launch of its first foldable phone and Pixel-branded tablet. This year, the company is going to supercharge its apps, services, and Android operating system with AI technology. We discuss this and more on Orbital, the Gadgets 360 podcast. Orbital is available on Spotify, Gaana, JioSaavn, Google Podcasts, Apple Podcasts, Amazon Music and wherever you get your podcasts.
