News: Mac Pro 2022 On The Way – Path To The M1 "Ultra Ultra", Leaker Reveals Rough Schematics

The standard M1's already stellar performance received an even further upgrade with the release of the M1 Pro and M1 Max, which took the same base design as the standard chip but added more cores. The M1 Pro and Max differ in terms of graphical performance – although both chips have 10 CPU cores, the M1 Max possesses 32 GPU cores as opposed to the M1 Pro's 16. However, both of these chips have since been outdone by Apple's newest processor, the M1 Ultra – an "Ultra Fusion" of two M1 Max chips resulting in 20 CPU cores, 64 GPU cores, a neural engine with 32 cores, 800 GB/s memory bandwidth, and up to 128 GB of RAM. A comparison of the various M1 chips can be found here.

A Massive Increase In Cores
Whether or not Apple will continue to follow the current strategy of increasing the number of cores with each chip tier – and how long the company will continue being able to do so, has been the focus of many discussions on Apple forums. According to a respected leaker, the end of the flagpole is not even close to having been reached. He claims to have uncovered a blueprint of the chip intended for the upcoming Mac Pro. The schema reveals an absolute monster of a chip under the codename "Redfern". Whereas the M1 Ultra was a combination of two M1 Max chips, Redfern will be a combination of two M1 Ultras with 40 CPU cores and 128 GPU cores. This corresponds to the values that Bloomberg predicted more than two years ago as Apple's development goal for the Mac Pro.

No Other Chip Manufacturer Capable Of Competing
Of course, it remains to be seen what Apple will call the upcoming M1 "Mega Ultra Ultra". As performance has thus far been directly tied to the number of cores in practical benchmarks – and since there were only a few "friction losses" to expected performance in these tests, we can already get a pretty good idea of the massive increase to performance that's on the way. The GeekBench score according to this schema would be in the 48,000 range, putting Apple way ahead of other chip manufacturers in terms of performance. The AMD Ryzen Threadripper 3990X with 64 cores currently has a score of 25,000, just barely beating out the M1 Ultra in GeekBench benchmarks. However, the current top dog would still be leagues behind the chip expected for the Mac Pro. That being said, rumors about the Mac Pro are currently a little mixed. Some sources mention a possible release in summer on the occasion of the WWDC, whereas others don't expect anything until late fall – Ming Chi-Kuo even mentioned a possible wait until 2023.
