The M2 Ultra Mac Pro: Key Limitations Compared to Intel Model
Written on
Apple's journey to launch the next-generation Mac Pro equipped with the M2 Ultra chip marks the end of its Intel-based machines. Initially expected to transition its entire lineup by 2022, Apple faced criticism for not fulfilling this promise. The speculation surrounding the Mac Pro's future led some to believe it would be replaced by the Mac Studio. Thus, the unveiling of the Mac Pro at WWDC23 came as a surprise, even though its design closely mirrors the Mac Studio.
With the introduction of the M2 Ultra, Apple can concentrate on developing software tailored to its own chips, sidelining Intel entirely. The new Mac Pro is touted as the most powerful workstation Apple has produced, though the upgrade options are notably limited compared to its Intel predecessor.
Display Support
The M2 Ultra Mac Pro can support up to eight 4K displays, six 6K displays, or three 8K displays. In contrast, the Intel version could handle up to twelve 4K displays or six 5K displays, depending on the configuration. Apple has released support documents detailing the external display combinations for both the new Mac Studio and Mac Pro, with the M2 Ultra configuration allowing for up to eight 4K displays at 60Hz.
Memory and Graphics
The Intel Mac Pro was the only model offering significant configuration options. The new model, however, presents limited upgrade opportunities due to the architecture of Apple's Silicon chips. While the M2 Ultra chip can support a maximum of 192 GB of RAM, the previous Intel version could be configured with up to 1.5 TB. This limitation arises from the unified memory design, which is intended to enhance performance but restricts expandability.
In terms of graphics, the M2 Ultra can accommodate a 76-core GPU, whereas the Intel model allowed for various graphics card options. While Apple's streamlined approach eliminates the need for external graphics, it raises questions about the performance capabilities of the M2 Ultra in demanding applications.
Chassis
The physical design of the Mac Pro remains unchanged, maintaining the same dimensions as its predecessor. However, the new model is slightly lighter due to the absence of certain components like the MPX Module.
Performance Insights
Early performance tests have shown that the M2 Ultra chip significantly outperforms the previous Intel variant, with benchmark scores indicating it may be more than twice as powerful. Yet, the lack of support for external graphics cards remains a concern for users who may require more robust graphics performance.
In conclusion, while the M2 Ultra Mac Pro is a powerful machine, it presents limitations compared to its Intel predecessor, particularly in terms of display support, memory expandability, and graphics options.
