Google continues to reserve some key details of the Pixel 7 and Pixel 7 Pro, its next flagship smartphones. One of them is the information related to the G2 tensioner, the second generation of its own chip which, presumably, could come with significant improvements in terms of performance and energy efficiency. The data on this chip, however, has been revealed ahead of time thanks to a new benchmarkand reveal, unfortunately, few relevant changes with respect to its predecessor in some areas.
According to leaked data in the performance test, The Tensor SoC of the Google Pixel 7 and Google Pixel 7 Pro will keep the same CPU as the processor of the Pixel 6. That is to say, it will have an eight-core CPU, in which two of them will be Cortex-X1, another two will be Cortex-A76 and the remaining four; Cortex-A55. The new chip manufacturing process, which will be 4 nanometers from the original Tensor’s 5 nanometers, however, will see the clock speeds of several of the cores improve slightly.
For example, the Tensor G2’s Cortex-X1s will run at a maximum speed of 2.85 GHz, compared to 50 MHz for its predecessor. The two Cortex-A76 cores will instead run at 2.35 GHz compared to 100 MHz for the previous SoC. This increase in speed would offer, according to the leaker Kuba Wojciechowski, about a 10% improvement in multicore performance versus the first generation Tensor. Performance on a single core, however, would be very similar to last year’s model.
The Tensor G3 GPU that will arrive with the Google Pixel 7, up to 20% more powerful
Google does seem to have modified the GPU of the Tensor G3, the chip that will arrive with the Google Pixel 7 and Pixel 7 Pro. This one, in particular, will go from a Mali-G78 to a Mali-G7010 which, according to ARM data, is up to 20% faster compared to the previous generation. Also up to 20% more efficient and up to 35% more powerful in machine learning related tasks.
The GPU enhancements in the Tensor processor, however, they do not make the Google Pixel 7 and Pixel 7 Pro compete in performance against other premium models on the market. Its Geekbench score, in fact, is considerably lower than other competing smartphones. The 1,068 points in a single core are, for example, well below the 1,882 points achieved by the A16 Bionic chip in the iPhone 14 Pro. Something similar happens in the multi-core tests. The Pixel 7 Tensor, for example, gets 3,149, while the A16 Bionic exceeds 4,000 points.
