If you buy an iMac or a MacBook, you also get a fantastic, high-resolution screen, which will be perfect for editing and playing video content. They have fast processors, capable of encoding video files quickly, and they’re stylish well-built machines. Given the dramatic improvements we can expect in both performance and battery-life, I’m bracing my wallet for the day one purchase of the 2021 16-inch MacBook Pro to replace my existing Intel model.As with other creative pastimes, video editing is great on Macs. Doubling the GPU cores ought to do it.įinally, he suggests that Apple will need to double the A14’s 128-bit memory bus to 256-bits to ensure that memory bandwidth isn’t a bottleneck for GPU performance. While we’ve been very impressed with the relative performance of the GPU in the M1-we find it punches way above its 2.6-teraflop weight class-but it’s still going to need a big boost if it wants to speed past the Radeon chips Apple ships in its products today. We’re looking at a range of around eight teraflops to 12 teraflops of processing power, and perhaps more importantly, lots of dedicated high-speed GDDR6 memory. The 27-inch iMac can feature anything from a Radeon Pro 5300 with 4GB of RAM to a 5700XT with 16GB. The 16-inch MacBook Pro offers a Radeon Pro 5500M or 5600M with 4GB or 8GB of dedicated graphics memory, so we’re looking at about around five teraflops of graphics processing power. The larger MacBook Pros and iMacs have discrete AMD Radeon graphics processors, each with its own pool of high-speed memory. But of all the upgrades, this is the most necessary to replace what Apple already has on the market. A 16-core GPU (giving Apple 256 execution units) will certainly explode the size of an already huge system-on-chip. The M1 doubled the number of GPU cores in the A14 from four to eight, and we think the next step up in Apple Silicon will double it again. Where Cross and Bloomberg are in agreement is that we can expect a 16-core GPU. If so, the difference between the Intel and Apple Silicon models would be truly incredible. It’s worth noting here that Bloomberg has reported that the 2021 16-inch MacBook Pro would get 20 cores, rather than 12. With only four high-performance cores, the M1 almost catches up with an 8-core Core i9, and a single core is much faster. It makes sense for the next evolution to double them again to eight high-performance cores, for a total of 12 CPU cores. The M1 kept the four efficiency cores and doubled the high-performance cores to 4, for a total of 8 CPU cores. The A14 has four high-efficiency CPU cores (slower but low-power) and two high-performance cores (very fast but high-power). But Cross says that beating Intel’s 8-core i9 processor is a given either way. I’m not sure I agree with this: I can’t see any reason why Apple couldn’t have been working on the M2 and A15 chips at the same time. Frankly, it seems hard to believe that an M-series chip based on the A15 architecture would be ready to enter production already, so my guess is that any new Apple silicon chip shipping in 2021 will be based on the A14 and M1. M2 would make more sense if the chip were to be based on the architectural improvements of the A15 processor coming to iPhones and iPads this fall, while M1X makes more sense if it’s a souped-up M1. Jason Cross has been doing some speculating over at Macworld.įirst, he suggests that technically Apple ought to label the next-gen chip an M1X rather than an M2, though he acknowledges that the company might opt for M2 for marketing reasons. It’s currently unclear whether Apple will label the chip an M1X or M2, but either way, we can expect some pretty dramatic performance improvements over the current M1-based 13-inch MacBook Pro (above).Įxceeding the performance of Intel’s high-end CPUs doesn’t look like much of a challenge, but matching or beating the high-end GPUs available in build-to-order versions of the Intel machines could take more work… We’re expecting Apple to launch the 2021 16-inch MacBook Pro later this year, with Apple Silicon.
