The Apple M4 is currently only available in the iPad Pro, a 5.1 mm thin tablet without active cooling. A test with liquid nitrogen reveals how much performance Apple is potentially losing by not installing a fan.

The Apple M4 in the current iPad Pro recently impressed in initial benchmarks and not only outperformed the AMD Ryzen 9 8945HS and the Intel Core Ultra 9 185H, but also the Qualcomm Snapdragon X Elite. The Next_Floating_Brothers team has now published an interesting test on Chinese platform Bilibili, in which the back of the iPad Pro was cooled with liquid nitrogen.

Liquid nitrogen has a boiling point of -196 °C, so the Apple M4 has enormous thermal reserves during this test. In such a case, performance is primarily limited by the maximum power consumption limit imposed by Apple and the potentially restricted boost clock frequencies. Nevertheless, performance increases considerably - the chip with three performance and six efficiency cores achieves a remarkable single-core result of 4,001 points, making it around 6.2% faster than without liquid nitrogen cooling.


More than 4,000 points in Geekbench 6 is a record. As a quick glance at the Geekbench 6 best list reveals, an Intel Core i9-13900KS "only" achieves 3,110 points, an Apple iPhone 15 Pro 2,908 points and the Samsung Galaxy S24 Ultra only 2,167. The top model of the Apple M4 with four performance and six efficiency cores achieves a slightly lower single-thread performance of 3,977 points with liquid nitrogen cooling.

On the other hand, the multi-thread result rises to 14,905 points, which corresponds to a lead of around 1.6% over the iPad Pro without additional cooling. A Geekbench 6 run does not last long enough to test throttling, and the performance difference is likely to be correspondingly greater in longer benchmarks.
