A new benchmark has appeared that provides us with more information on the specifications of the Pixel 7 Pro, especially the enhancements made to the CPU and GPU in the Google Tensor G2 processor.
The release of the Pixel 7 and Pixel 7 Pro, 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 second version of the Google Tensor processor developed in partnership with Samsung, the “Tensor G2” chip, has been one of the major mysteries. Many have been curious about Google’s plans for the Tensor line after the Tensor had a good debut with the Pixel 6 series, despite the fact that it has subsequently fallen behind the competition over the last year.
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. 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.
All this, combined with the 4nm process node that’s used for the chip, contribute to a ~10% multi-core performance enhancement with a negligible single-core change. pic.twitter.com/lSLlpwHP1U

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. It’s feasible, though far from certain, that this design may aid in achieving that degree of efficiency, as Kuba hypothesizes.
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.
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.
