Ever since Google confirmed the existence of its custom-built SoC for Pixel phones, more and more sleuths have gone on an expedition to look for more hidden details. This is because while Google made its plans transparent, it didn’t reveal the true details. Now, thanks to some collaborative efforts of some keenly-eyed scouts we are now getting to know about some key details.
A source who claims to have a real Pixel 6 Pro contacted XDA developers and helped them divulging some important details about the CPU. This is the same source that also shared details on Pixel 6 Pro as well.
Well moving on, as per the publication’s learning, the Tensor chip has a tri-cluster core design. The report mentions that a recent Geekbench listing is also right about the CPU frequencies.
This is the following CPU configuration,
- 2x ARM Cortex-X1 clocked at 2.802GHz
- 2x ARM Cortex-A76 clocked at 2.253GHz
- 4x ARM Cortex-A55 clocked at 1.80GHz
The publication notes that it was able to cross-check the information from the CPU file CPU Info and came to this conclusion. It should be noted that previously, it was reported that the Tensor chip has two Cortex-A78 cores but according to new findings, the CPU has Cortex-A76 cores instead. The Cortex-A76 was announced back in mid-2018 and the successor, which is the latest in the market today is significantly better in terms of power. So, why Google is using older cores? Well, it is unknown at the moment. But, the publication was able to verify this detail by checking certain factors.
The publication also got to know that the Pixel 6 Pro will have the same GPU design as the Exynos Galaxy S21 - ARM Mali-G78. The name of the GPU, however, surfaced back in May in a comment on the Google Issue Tracker. But the exact microarchitecture of each CPU core is still unknown.
The publication is also able to comment on some other aspects of the phone. As per its findings, the Pixel 6 Pro can decode AV1 content at up to 4K resolution and 60fps. It can also decode HEVC content at up to 4K resolution and 120fps or 8K resolution and 30fps.
The report cites the source and confirms the Pixel 6 Pro also supports both aptX and aptX codecs, two Bluetooth audio codecs used by many wireless headsets on the market.
