Rumors suggest that the upcoming Snapdragon 8 Gen 4 will have an impressive GPU. An early AnTuTu result showed a GPU score of 1,330,057, a massive increase from the 896,416 points of the top Snapdragon 8 Gen 3 result currently on AnTuTu's ranking page.
According to The Ice UniverseThe Adreno 830 is tested at a clock frequency of 1,250 MHz. For comparison, the Adreno 750 in the 8 Gen 3 runs at 903 MHz for the standard AB variant and 1,000 MHz for the AC variant (usually labeled “for Galaxy” or “Leading”). The Adreno 735 in the 8s Gen 3 has fewer cores but runs at a higher frequency of 1,100 MHz.
Excited commenters on Weibo asked if the performance variant of the Snapdragon 8 Gen 4 would have even higher clocks – the leaker warned that these are still tests and the final clock speeds could be different.
The Snapdragon 8 Gen 4 will also have very high CPU clock speeds for its Oryon cores — a Geekbench result showed the two fast cores running at up to 4.09GHz (and the other six cores at 2.78GHz). For comparison, the highest CPU clocks on a phone are found inside the Apple A17 Pro chipset in the iPhone 15 Pro (3.78GHz). On the Android side, the Dimensity 9300+ and the Snapdragon 8 Gen 3 Leading are tied (3.4GHz).
This means that Qualcomm should be the first to break the 4 GHz barrier this October. In any case, it is the only smartphone that can do so, since the Apple M4 chip in the new iPad Pros runs its big processor cores at up to 4.4 GHz.
