We’re all eagerly awaiting the release of the Pixel 7 and Pixel 7 Pro, which will be fully unveiled on October 6 at Google’s hardware event. Even though Google gave us a sneak peek at the phones at Google I/O, there are still a lot of unconfirmed facts.
The impending “Tensor G2” chip, which is anticipated to be the second generation of the Google Tensor processor developed in partnership with Samsung, has been one of the major mysteries. Many have been wondering where Google will take the Tensor line next after making a great debut with the Pixel 6 series, although one that has subsequently fallen behind the competition over the previous year.
Google Pixel 7 Pro Tensor G2
Kuba Wojciechowski, an Android developer, did some thorough research on Twitter, and as a result, we now have convincing proof of the performance that the Pixel 7 Pro and its Tensor G2 CPU will provide. But first, a small caveat is necessary because a lot of the fresh data comes from a brand-new Pixel 7 Pro listing on Geekbench.
It should be mentioned that the data produced by Geekbench is quite simple to fake. Nevertheless, there are a number of minor characteristics that hint at the validity of this Pixel 7 Pro benchmark, which our team has also examined and validated. Nevertheless, these specifics need to be viewed with a grain of salt.
Analyzing the specifics, it appears that Google did not make many changes to the CPU cores employed between the Tensor G2 of this year and the Tensor of last year. Using the identical configuration of two Cortex-X1 cores, two Cortex-A76 cores, and four Cortex-A55 cores, but at significantly faster clock rates, is what can be deduced from the available information. The Tensor G2 and Pixel 7 Pro multi-core benchmark appear to have improved by roughly 10% as a result of the somewhat increased speeds paired with the reduced 4nm die size being employed.
Despite the initial disappointment, it’s conceivable that this may turn out for the best because the Pixel 7 won’t be improving on raw performance. The Pixel 7 and Tensor G2 need to catch up to the work the Snapdragon 8+ Gen 1 achieved in terms of heat reduction and power efficiency, as my colleague Ben Schoon pointed out. Though it’s far from certain, as Kuba hypothesises, this design could contribute to achieving that degree of efficiency.
The GPU of the Pixel 7 Pro, which goes from the Mali-G78 to the Mali-G710, is where the Tensor G2 specifications actually see a considerable improvement. The performance, power efficiency, and even machine learning performance of this new GPU, which is one of the main objectives of the Tensor series, are expected to improve by 20%, 20%, and even 35%, respectively.
One thing that has changed is the frequency. The A76 cluster has been bumped by 100 MHz, to 2.35 GHz, and the X1 cluster now runs 50 MHz faster than it did before, at 2.85 GHz. pic.twitter.com/xf3Apv4q1T

In keeping with that, there are hints that Google plans to add a new version of its “Janeiro”-codenamed Tensor Processing Unit (TPU) to the Tensor G2, which should give the Pixel 7 series an additional boost. The test very certainly confirms one more detail: the Pixel 7 Pro will probably have 12 GB of RAM, much as the Pixel 6 Pro.
Overall, it appears that users of the Pixel 6 series won’t find the Tensor G2 to be a particularly exciting upgrade in terms of hardware for the Pixel 7 Pro, but the gradual improvements may result in a more consistent experience. This may be just what you were searching for if you were waiting for Google to “figure out” its nascent Tensor family of processors.
