According to an alleged leak of performance tests of the new Apple M1X CPU, Macs are going to experience an even more radical power increase than with the first M1. The new CPU will be a serious threat to the high-end of AMD and Intel, with a much lower consumption and a similar power.
The filter, CPU Monkey, states that the Apple M1X will have 12 cores, an increase from the eight in the M1. It will supposedly have eight high-performance cores, called “Firestorm”, and four efficient ones, called “Ice Storm”.
The CPU will have an even more impressive improvement in the GPU: the supposed performance tests of a “preliminary sample” of the M1X indicate that the processor will feature a 16-core GPU with 256 execution units.
The M1 within the latest MacBook Pro and MacBook Air features an eight-core GPU with 128 execution units, suggesting that the M1X could offer up to twice the graphics performance.
The Apple M1X will also feature higher heat dissipation – from 35W to 45W. It is more than the M1 but well below its rivals AMD and Intel. The M1X, based on these tests, will be able to support up to 32GB of LPDDR4X memory and PCIe 4.0 storage.
The chip will continue to run at 3.2 GHz like the M1, claims the leaker, and will continue to use the five-nanometer production process – the key to its speed and low power consumption.
CPU Monkey says the Apple M1X will debut in Q2 2021 on a 14-inch MacBook Pro, a 16-inch MacBook Pro and a new 27-inch iMac.
Other rumors indicate that the M1X is not the only high-end processor. There will be 16-core and 32-core versions, presumably for the Mac Pro.
If these rumors are confirmed, it will be very bad news for Intel and AMD, because the Apple M1 is already destroying Intel and AMD in multiple tests. These new versions will be absolutely terrifying.
