A new test has surfaced that provides us with a clearer picture of the Pixel 7 Pros’ specifications, especially the enhancements made to the Google Tensor G2 chip’s CPU and GPU.
We’re all eagerly awaiting the release of the Pixel 7 and Pixel 7 Pro, which will be formally unveiled at Google’s hardware event on October 6. Even though Google gave us a sneak peek at the phones at Google I/O, there are still a lot of unconfirmed details.
The second generation of the Google Tensor processor developed in partnership with Samsung, the Tensor G2, has been one of the major mysteries. Many have been wondering where Google will take the Tensor line next after making a great debut in the Pixel 6 series, albeit one that has since fallen behind the competition over the last year.
We now have solid proof of the performance gains the Pixel 7 Pro and its Tensor G2 chip will make, thanks to some skillful digging by Android developer Kuba Wojciechowski on Twitter. But first, a small warning is necessary because the most of the new details come from a fresh Geekbench listing for the Pixel 7 Pro.
It should be noted that the information provided by Geekbench can be falsified pretty easily. Nevertheless, there are a number of minute elements that our staff has carefully examined and verified that support the validity of our Pixel 7 Pro benchmark. Nevertheless, these specifics need to be viewed with a grain of salt.
If you look closely, it appears that Google did not make much changes to the CPU cores used between Tensor G1 and G2 this year. Despite having somewhat higher clock speeds, it appears to be employing the same configuration of two Cortex-X1 cores, two Cortex-A76 cores, and four Cortex-A55 cores. The Tensor G2 and Pixel 7 Pro multi-core benchmark appears to have improved by roughly 10% as a result of the somewhat increased speeds paired with the reduced 4nm die size being employed.
While first disheartening, it’s likely that this will turn out for the best because the Pixel 7 won’t be able to improve on raw performance. The Pixel 7 and Tensor G2 need to catch up to the work the Snapdragon 8 Gen 1 did in terms of heat reduction and power efficiency, as my colleague Ben Schoon pointed out. As Kuba speculates , it’s plausible, though not definite, that this design could contribute to reaching that level of efficiency.
However, the GPU of the Pixel 7 Pros Tensor G2 receives a major upgrade, moving from the Mali-G78 to the Mali-G710. This new GPU is set to offer is 35% better for machine learning use, one of the main objectives of the Tensor line, and has 20% better performance and 20% better power economy.
In light of this, there are also signs reports that Google plans to add a new version of its Tensor Processing Unit (TPU), known as Janeiro, 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 owners 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 might be the solution you were seeking for if you were waiting for Google to work out their nascent Tensor series of chips.
