We’re anticipating Apple to launch the 2021 16-inch MacBook Pro later this yr, with Apple Silicon. It’s at present unclear whether or not Apple will label the chip an M1X or M2, however both method, we are able to anticipate some fairly dramatic efficiency enhancements over the present M1-based 13-inch MacBook Professional (above).
Exceeding the efficiency of Intel’s high-end CPUs doesn’t appear to be a lot of a problem, however matching or beating the high-end GPUs obtainable in build-to-order variations of the Intel machines might take extra work…
Jason Cross has been doing a little speculating over at Macworld.
First, he means that technically Apple must label the next-gen chip an M1X relatively than an M2, although he acknowledges that the corporate may go for M2 for advertising causes.
M2 would make extra sense if the chip had been to be based mostly on the architectural enhancements of the A15 processor coming to iPhones and iPads this fall, whereas M1X makes extra sense if it’s a souped-up M1. Frankly, it appears exhausting to consider that an M-series chip based mostly on the A15 structure can be able to enter manufacturing already, so my guess is that any new Apple silicon chip delivery in 2021 might be based mostly on the A14 and M1.
I’m undecided I agree with this: I can’t see any purpose why Apple couldn’t have been engaged on the M2 and A15 chips on the similar time. However Cross says that beating Intel’s 8-core i9 processor is a given both method.
The A14 has 4 high-efficiency CPU cores (slower however low-power) and two high-performance cores (very quick however high-power). The M1 saved the 4 effectivity cores and doubled the high-performance cores to 4, for a complete of 8 CPU cores. It is smart for the subsequent evolution to double them once more to eight high-performance cores, for a complete of 12 CPU cores.
With solely 4 high-performance cores, the M1 nearly catches up with an 8-core Core i9, and a single core is far quicker. Think about 8 high-performance cores!
It’s value noting right here that Bloomberg has reported that the 2021 16-inch MacBook Professional would get 20 cores, relatively than 12. In that case, the distinction between the Intel and Apple Silicon fashions can be actually unimaginable.
The place Cross and Bloomberg are in settlement is that we are able to anticipate a 16-core GPU.
The M1 doubled the variety of GPU cores within the A14 from 4 to eight, and we predict the subsequent step up in Apple Silicon will double it once more. A 16-core GPU (giving Apple 256 execution items) will definitely explode the dimensions of an already large system-on-chip. However of all of the upgrades, that is probably the most needed to switch what Apple already has in the marketplace. The bigger MacBook Execs and iMacs have discrete AMD Radeon graphics processors, every with its personal pool of high-speed reminiscence.
The 16-inch MacBook Professional presents a Radeon Professional 5500M or 5600M with 4GB or 8GB of devoted graphics reminiscence, so we’re about round 5 teraflops of graphics processing energy. The 27-inch iMac can function something from a Radeon Professional 5300 with 4GB of RAM to a 5700XT with 16GB. We’re a spread of round eight teraflops to 12 teraflops of processing energy, and maybe extra importantly, numerous devoted high-speed GDDR6 reminiscence.
Whereas we’ve been very impressed with the relative efficiency of the GPU within the M1—we discover it punches method above its 2.6-teraflop weight class—but it surely’s nonetheless going to wish an enormous enhance if it desires to hurry previous the Radeon chips Apple ships in its merchandise right this moment. Doubling the GPU cores must do it.
Lastly, he means that Apple might want to double the A14’s 128-bit reminiscence bus to 256-bits to make sure that reminiscence bandwidth isn’t a bottleneck for GPU efficiency.
Given the dramatic enhancements we are able to anticipate in each efficiency and battery-life, I’m bracing my pockets for the day one buy of the 2021 16-inch MacBook Professional to switch my existing Intel model. Particularly as I’m anticipating the resale worth of my present machine to take an enormous hit…
