Next quarter, Apple is expected to reveal MacBook Pro laptops that use the M1X SoC. Take it with a grain of salt, but the new leak indicates the M1X will feature 12 processor cores. The chip reportedly has eight high-performance cores and four energy-efficiency cores. The GPU also receives a major upgrade to 16 cores, which is good for 256 execution units.
What it boils down to is that the M1X has double the high-performance cores and also twice the number of GPU cores versus the current M1 SoC. RAM support is allegedly increased to 32GB and there's talk about support for up to three external displays. The TDP is a lot higher of course:
It’s also possible that with a single machine featuring the M1X, users can hook up to three external monitors for maximizing their workspace real estate. Overall, these specifications show that the next Apple Silicon is a major upgrade over the M1, but at the cost of increased TDP. The table shows that to obtain this level of performance, the TDP could operate at 35W, and depending on the workload, that value could go up to 45W if required.Via: WCCF Tech
