performance analysis and comparison


Google Pixel 6 And Google Pixel 6 Pro they have been presented for a few months now, more precisely on October 19, 2021, and as you have no doubt seen we have already had the opportunity to try them well during this period (we talk about them in our reviews, which you can find at the bottom). Since the Italian launch should be getting closer and closer, in these days we have decided to take a more in-depth look at the new chipset used by Big G, that is the much talked about Google Tensor: let’s take a closer look and analyze performance and efficiency with some benchmarks.

Let’s take a closer look at the Google Tensor of Pixel 6 and Pixel 6 Pro: the technical specifications

Google Tensor is the first chipset designed for the Pixels and was created specifically for the Google Pixel 6 and Pixel 6 Pro (although something has been boiling in the pot since the Pixel 5). Internally referred to as GS101 (and formerly also called with the code name “Whitechapel”), it is a SoC octa core with four high-efficiency cores, two intermediate and two high-power: respectively we have four Cortex-A55 cores at 1.80 GHz, two Cortex-A76 at 2.25 GHz and two Cortex-X1 at 2.80 Hz (i details below). The Mountain View house claims that the chip guarantees 80% higher performance than the Pixel 5 (which has a Qualcomm Snapdragon 765G) in terms of the CPU and 370% on the GPU side.

According to what they say in Mountain View, the chip was entirely designed by the company (“designed“): In reality on balance it should be the result of a collaboration with Samsung LSI, and the identification of the chip itself seems to be a further indication given that it seems to follow in some way that of the Exynos.

Beyond all this, here are the Technical specifications of the Google Tensor:

  • CPU:
    • 2 x Cortex-X1 @ 2.8 GHz 2 × 1024 KB pL2
    • 2 x Cortex-A76 @ 2.25 GHz 2 × 256 KB pL2
    • 4 x Cortex-A55 @ 1.8 GHz 4 × 128 KB pL2
    • 4 MB sL3
  • GPU: Mali G78 MP20 @ 848 MHz (shaders) @ 996 MHz (tiler / L2)
  • production process: 5 nm
  • Memory Controller: 4 x 16-bit CH, @ 3200 MHz LPDDR5 / 51, 2 GB / s, 8 MB cache
  • ISP: Google ISP + Hydrid Exynos
  • NPU: Google Edge TPU @ 1066 MHz
  • support 8K 30fps, 4K 120, 8K 60, H.265 / HEVC, H.264, VP9, ​​AV1
  • modem: Exynos 5123 external (LTE Category 24/18, 5G NR Sub-6, 5G NR mmWave)

To make the Tensor what it is, the TPU Tensor Processing Unit: it is an AI accelerator consisting of an ASIC circuit developed by Google itself, specifically designed for applications in the field of neural networks and machine learning. The Mountain View company has been working on it for several years with the aim of perfecting efficiency and being able to exploit the most sophisticated machine learning algorithms: this translates into the possibility of being able to exploit numerous features based on Artificial Intelligence, from the point of photographic view (Magic Eraser, Motion Mode, Real Tone) and more (advanced speech recognition, Live Translation and so on).

Since we were talking about Exynos, it is interesting to take a look at some technical data also of the latest arrival from Samsung, for a small comparison. We obviously speak ofExynos 2100the SoC that forms the heart of the Samsung Galaxy S21 series: there is some similarity, don’t you think?

  • CPU:
    • 1 x Cortex-X1 @ 2.91 GHz 1 × 512 KB pL2
    • 3 x Cortex-A78 @ 2.81 GHz 3 × 512 KB pL2
    • 4 x Cortex-A55 @ 2.20 GHz 4 × 64 KB pL2
    • 4 MB sL3
  • GPU: Mali G78 MP14 @ 854 MHz
  • production process: 5 nm
  • Memory Controller: 4 x 16-bit CH, @ 3200 MHz LPDDR5 / 51, 2 GB / s, 8 MB cache
  • ISP: Full Exynos + DSP
  • NPU: Exynos NPU @ 1352 MHz
  • support 8K 30fps, 4K 120, 8K 60, H.265 / HEVC, H.264, VP9, ​​AV1
  • modem: Exynos 5123 integrated (LTE Category 24/18, 5G NR Sub-6, 5G NR mmWave)

Google Tensor Performance: The Google Pixel 6 and Pixel 6 Pro benchmarks

Now that we have pitted the technical data, let’s check the performance of the Google Tensor obtained with Google Pixel 6 and Pixel 6 Pro. We “stressed” the two smartphones with a few benchmarks each, obtaining similar results even if not identical. In fact, we remind you that the two devices do not have the same identical technical specifications.

Google Pixel 6 data sheet

In the Geekbench benchmark (version 5.4.4) the Tensor on board of Google Pixel 6 managed to obtain a score of 1050 points in the single core and 2851 points in the multi core. Score not very far from that obtained by the older brother Pixel 6 Pro, which in our test scored 1037 points in the single core and 2837 in the multi core (the small differences may be due to many factors).

If, on the other hand, you prefer the response provided by the Wild Life Extreme test of 3DMarkGoogle Pixel 6 Pro goes up to 2069 points, with an average frame rate of 12.4 fps, while Google Pixel 6 “stops” at 1940 points, with an average frame rate of 11.8 fps. All tests were performed with the same software version, the latest made available by Big G and based on Android 12. For the uninitiated, the Geekbench benchmarks focus on the CPU, while those of 3DMark test above all the GPU.

Since we have talked about it, we enclose for comparison the same tests performed to whip theExynos 2100 of Samsung, in these cases aboard Samsung Galaxy S21 And Samsung Galaxy S21 Ultra (we did not consider the Plus model due to the identical hardware to that of the S21, apart from the diagonal of the display). Here too obviously with Android 12. As you can see, the result is perfectly comparable as regards the 3DMark Wild Life Extreme test: Galaxy S21 reaches 1960 points, with an average frame rate of 11.7 fps, while Galaxy S21 Ultra is remained at 1862 points (11.2 fps).

With Geekbench, the Exynos 2100 instead gives Samsung smartphones a bit of an advantage in the multi core: Galaxy S21 reaches 1044 points in the single core and 3197 in the multi core, with Galaxy S21 Ultra that goes a little higher arriving at 1075 and 3327 points respectively.

If after having a look at the numbers you want to get information regarding the “everyday” performances offered by the Tensor on board the Google Pixel 6 and Google Pixel 6 Pro, you have our detailed reviews. All this while waiting to see both officially in Italy: as promised by the Mountain View house it should not be long before the debut in our country.

Finally, we remind you that Big G’s customized chip should also be the heart of Google Pixel 6a, the mid-range smartphone expected by the second quarter of 2022: obviously we will not fail to test it properly.
