The new MacBook Air and MacBook Pro based on fresh Apple M2 chips will not be available until July. However, the first independent data on the performance of their processors has already appeared on the Internet. They were found in the Geekbench 5 synthetic test database, writes the Tom’s Hardware portal.
Computing power in the single-core Geekbench 5 test for Apple M2 chips compared to Apple M1 is up to 10% higher, and multi-core – up to 16%. Graphics performance has been increased even more, up to 67% faster than the previous generation Apple M1 graphics chips. The comprehensive Geekbench 5 test doesn’t reflect real-world performance in some scenarios, but the integer and floating-point benchmarks give you an idea of what to expect from Apple’s new chips.
Apple uses the same computing and graphics architectures in the M2 processors that it uses in the Apple A15 mobile SoCs for smartphones. However, the new chips will be built using TSMC’s optimized 5nm N5P process. Because of this, its powerful Avalanche cores can run at up to 3.49GHz, which is 10% faster than the M1’s Firestorm cores. Blizzard’s energy-efficient cores are also faster than the Icestorm cores of previous Apple M1 chips. However, the main increase in the performance of the Apple M2 is not due to an increase in IPC (the number of instructions executed per clock), but to a higher operating frequency, larger cache memory and improved performance of the storage subsystem.
In general, the single-threaded computing power of the Apple M2 is not much higher than that of the predecessor. However, the new Avalanche cores are significantly faster than the Golden Cove cores used in 12th Gen Intel Core (Alder Lake-H) mobile processors. The Apple M2’s multi-threaded performance is 16% faster than the M1. But it lags behind the mobile Alder Lake-H.
Most impressive is the increase in graphics performance in the new Apple processors. It’s up to 67% faster than the Apple M1 graphics. This is mainly because Apple has increased the number of graphics clusters in the M2. There are now ten instead of eight. In addition, as mentioned above, it uses a new graphics architecture, the same as the Apple A15 mobile chips.
