Google Pixel 7’s Tensor G2 benchmarks just tipped big improvements

Fresh off the back of revealing the Pixel Tablet’s middling specs and the existence of a Chromecast HD, developer Kuba Wojciechowski (opens in new tab) has spotted a Geekbench listing for the Pixel 7’s Tensor G2 chip. 

The listing for the upcoming Pixel 7 Pro shows the same mix of two Cortex-X1 cores, two Cortex-A76 cores and four Cortex-A55 cores as the first generation, but with marginally faster clock speeds of between 50 and 100MHz. This minor boost, plus the introduction of the 4nm fabrication process results in a score that’s about 10% faster than the Pixel 6 in multi-core tests, with a barely perceptible single-core improvement.

That may sound underwhelming, but there are a few reasons to be very optimistic indeed. 

Not only is this based on pre-release hardware that could yet be optimized but, as Wojciechowski points out, sticking with tried-and-tested architecture with a slight improvement could be a boon to battery life and might give the Pixel 7 Pro the best phone battery life

“The current trend in Arm cores is improving the performance at the cost of worse efficiency and high power use,” he tweeted. “By keeping the older cores Google avoids getting those characteristics.”

That could be significant, as Pixel 6 battery life proved extremely disappointing in our tests, clocking in at around the eight-hour mark for both the regular and Pro models. That was around two hours behind the Samsung Galaxy S21 and two-and-a-half hours shy of the standard iPhone 13. Any boost there would be very welcome indeed.

Plus, while Geekbench’s CPU scores only show a modest advance, all the signs point to significantly stronger GPU performance. Wojciechowski writes that Google has switched from the Mali-G78 to the Mali-G710 which, if Arm’s projections are correct, should offer a 20% boost to games, a similar uplift in efficiency and a massive 35% improvement to machine learning.

“Google runs a huge part of their Google Camera pipeline on the GPU on their Tensor devices,” Wojciechowski writes. “It will certainly improve that considerably, as well as make the new Pixels way better at gaming.”

While Wojciechowski cautions that Geekbench listings can be spoofed, he states his belief that this one is legitimate due to details that only a keen-eyed developer would spot.

We’ll find out soon enough. Google has an event to unveil its new flagship smartphones, as well as the brand new Pixel Watch, on October 6. If the company can boost performance in the way suggested here while keeping pricing competitive, Google could well have a winner and one of the best Android phones on its hands.
