On March 14, Twitter blogger @Majin Bu broke the news that Apple will launch the 2022 Mac Pro in September this year, and Apple is also ready to carry a new custom chip, codenamed "Redfern", which may have a 40-core CPU, which may become the strongest Apple device on the surface.
At the press conference on March 9, Apple launched the M1 Ultra custom processor, using ultraFusion package architecture, the two M1 Max dies using a silicon intermediation layer for internal interconnection, achieving 20 core CPU, 64 core GPU. The performance of the M1 Max has long been obvious to all, and it is really hard to imagine how strong the M1 Ultra, which is spliced by two M1 Maxes.
Apple used this horrible M1 Ultra in Mac Studio, and the mac pro with higher positioning will certainly be stronger than the former. If Apple wants to close the performance gap between the two devices, it must prepare a chip with stronger performance than the M1 Ultra. At this time, Apple only has two choices, either to re-develop a new processor, or to stitch the M1 Ultra into a stronger chip. Both approaches are obviously simpler and less expensive.
According to Apple's UltraFusion package architecture, there is really a chance to stitch two M1 Ultras together to obtain a stronger chip with 40 core CPU, 128 core GPU, and support 256GB of unified memory. Foreign media wccftech has made a scenario for Apple, if this chip really exists, then the performance of the Mac Pro will be beyond belief, of course, the price may also be expensive to fly, the top version of the blind guess more than 100,000 yuan.
So is it possible that Apple will actually stitch the two M1 Ultras together to form a stronger chip? Xiao Lei felt that the possibility was very large. Apple's M1 Max is based on TSMC's 5nm process, which is likely to be the most powerful processor that can be made under the 5nm process. If you want to further improve the performance of the processor, you can either wait for the process to be upgraded, or make the size of the chip larger.
If Apple chooses to re-develop a larger chip, the cost of research and development and production will increase significantly, and it will be difficult to mass-produce and use it in the short term. However, if chip splicing technology is used, Apple only needs to continuously produce M1 Max and splice it into different chips through packaging technology, and the production cost will be much lower and the production capacity will be relatively guaranteed.
So, the possibility of Apple using two M1 Ultras on the 2022 Mac Pro is very large, and I'm really curious about how strong this product really is, so stay tuned.
