Google's Tensor G4 for Pixel 9: A Modest Upgrade with Surprising Implications
As the launch of Google's Pixel 9 series approaches on August 13, leaked information about the new Tensor G4 chip reveals a surprisingly minor upgrade from its predecessor. This development raises questions about Google's chip strategy and the potential for future Pixel devices.

Key Changes in Tensor G4
- CPU Configuration: The Tensor G4 adopts a 4+3+1 layout using newer ARMv9.2 cores (Cortex-A520, Cortex-A720, and Cortex-X4), compared to the G3's 4+4+1 arrangement.
- Clock Speeds: Slightly higher clock speeds across all cores.
- GPU: Same Mali-G715 GPU as G3, but clocked higher at 940 MHz (up from 890 MHz).
- Modem: New Exynos Modem 5400, offering satellite connectivity and up to 50% better power efficiency.

Performance Expectations
Early Geekbench results suggest modest improvements:
- Single-core performance: ~11% increase
- Multi-core performance: ~3% increase
However, these figures should be taken with caution until official benchmarks are available.

The Unexpected Twist
Surprisingly, many of Google's custom IP blocks remain unchanged in the G4:
- Edge TPU (ML accelerator)
- GXP (Digital Signal Processor)
- BigWave (AV1 encoder/decoder)
- Titan M2 security chip
This minimal upgrade appears to be a result of Google missing a deadline for a fully custom chip codenamed redondo, forcing them to collaborate with Samsung once more for the Tensor G4.
Implications for Pixel 9 Features
The minor nature of this upgrade suggests that any Pixel 9-exclusive features may be artificially locked, rather than hardware-dependent. This opens up the possibility of porting these features to older Pixel devices, as has been done in the past.
Looking Ahead
While the Tensor G4 may not be the leap forward some were hoping for, it does offer some improvements, particularly in modem efficiency. However, this development raises questions about Google's long-term chip strategy and the future of truly custom silicon in Pixel devices.
As we await the official unveiling of the Pixel 9 series, it will be interesting to see how Google positions these devices and what unique features they may offer, given the modest nature of the Tensor G4 upgrade.
Update: Friday August 02 21:26
Leaked renders of the Pixel 9 series reveal design details and color options. The Pixel 9 features a flat design with a disconnected camera island, available in Porcelain, Rose, Green, and Obsidian. The Pixel 9 Pro sports a color-matched polished metal frame, possibly stainless steel, in Porcelain, Rose, Hazel, and Obsidian. A Pixel 9 Pro Fold is rumored, featuring an 8-inch OLED display when unfolded. All models have centered punch-hole front cameras and pill-shaped rear camera cutouts. Pre-order deals may include storage upgrades and Google One AI Premium subscriptions. The Pixel 9 series is expected to launch alongside the Pixel Watch 3 and Pixel Buds Pro 2 on August 13th.
