Google Pixel 6 and Pixel 6 Pro GPU details emerge
@akes29 has discovered the GPU that Google plans to use in its next Pixel smartphones. According to XDA Developers, @akes29 found the GPU detail in a Google Issue Tracker comment, which you can read below. The comment refers to the P21, a codename thought to cover the Pixel 6 series. P21 has been seen in connection with GS101 too, seemingly a codename for Google's in-house SoC.
The comment includes a logcat that lists the P21's GPU as a Mali-G78, the GPU that Huawei and Samsung use in the Kirin 9000 and Exynos 2100, respectively. The ARM Mali-G78 supports up to 24 GPU cores, as seen with the Mali-G78 MP24 in multiple Huawei flagship smartphones using the Kirin 9000.
However, Samsung uses a 14 core version in the Exynos 2100, a comparison between which you can read here. In short, the MP24 consistently outscores the MP14ARM Mali-G78 MP14 GPU - Benchmarks and Specs in 3DMark, and by up to 78% in some cases.
The logcat does not reveal how many cores the P21's GPU has, nor its model number. Nonetheless, both Mali-G78 variants offer significantly better performance than the Pixel 5's Adreno 620 does. You can read a comparison between the MP14, MP24 and Adreno 620 here. The Mali-G78 can outscore the Adreno 660 (Snapdragon 888) in benchmarks too, albeit only the 24-core variant.
