Benchmarked: The Google Tensor G2 versus the competition


Oct 13, 2022

The Pixel 6 series was a landmark release for Google in many ways, introducing ultra-competitive pricing, upgraded cameras, and a semi-custom Tensor system on a chip (SoC) for the first time. Google’s brand-new Pixel 7 series picks up where the Pixel 6 left off, offering the same pricing and similar cameras, but a new Tensor G2 chipset. We’ve already covered the Tensor G2 in our deep dive, taking a look at specs and features. But now that we have the Pixel 7 series phones in our hands and can share our test findings, let’s take a look at how it fares in benchmarks against the first generation Tensor chip and the best rival silicon.

How does Google’s new chip stack up on paper?

At first glance, it looks like the Tensor G2 isn’t a huge upgrade over the original Tensor processor. The CPU still looks similar to the Pixel 6 chipset, with two Cortex-X1 heavy cores and four little Cortex-A55 cores. Google does provide a tiny 50MHz clock speed boost for the X1 cores. However, the two medium Cortex-A76 cores seen in the original SoC have been replaced by two Cortex-A78 cores.  By comparison, the Snapdragon 8 Gen 1 family, Samsung Exynos 2200, and Mediatek Dimensity 9000 series all offer much newer CPU components. It stands to reason that the Tensor G2 won’t surpass those SoCs when it comes to CPU benchmarks. But what about the GPU?
