The 2023 Mac Pro is the first of its kind to feature Apple silicon and all previous models had Intel processors. While the machine loses support for eGPUs, it is around twice as powerful as the previous top-tier Mac Pro while maintaining a mostly modular design with seven PCIe slots. Even so, some first-time Mac Pro customers or users of the 2013 model may be able to obtain a 2019 Mac Pro second-hand or from a third-party retailer for a substantially lower price, so it will be important to weigh up exactly what was added with each new version of the machine.

Upgrade to the 2023 Mac Pro?
In most workflows, the M2 Ultra chip should offer a massive performance improvement over the Intel Xeon W processors offered in the 2019 Mac Pro, especially in CPU-intensive tasks. Early benchmarks indicate that it delivers around two-times faster overall CPU performance than the fastest Intel-based Mac Pro with a 28-core Xeon W processor.
For machine learning processes, the 2023 Mac Pro has a significant advantage with the M2 Ultra's 32-core Neural Engine. Likewise, its dedicated media engine offers considerable benefits in video editing workflows.
The new Mac Pro can support 8K external displays for the first time. It also has newer Wi-Fi and Bluetooth specifications, as well as two USB-A ports and support for high-impedance headphones.
If you're looking for a high-end, future-proof machine that harnesses the best available performance with Apple silicon, as well as its more modern specifications, it will be worth opting for the new Mac Pro.
...Or Stick With the 2019 Mac Pro?
Not all 2013 or 2019 Mac Pro users should upgrade to the 2023 model. Most notably, the 2019 Mac Pro features an Intel chip. While support for Apple silicon is now much better in professional workflows than it was upon its launch in 2020, some niche applications and legacy software may still work better on an Intel architecture. Likewise, some users may wish to dual-boot Windows via Boot Camp and this is not possible on the new Mac Pro.
If you require support for additional graphics cards, only Intel-based Macs can support this. This means the new Mac Pro's PCIe slots are only useful for things like digital signal processing (DSP) cards, serial digital interface (SDI) I/O cards, additional networking, and built-in storage, so if you need eGPUs, the 2019 Mac Pro is still your best option.
The new Mac Pro maxes out at 192GB of memory. The previous model supported almost eight times this amount, so if you need vast amounts of memory, the 2019 model is still better for your purposes. Similarly, the 2019 model's memory is user-upgradeable. The 2019 Mac Pro supports four more 4K displays than the 2023 model and it also has four more Thunderbolt ports, which may be important considerations for some users.
Hence, for the right price, the 2019 Mac Pro may still be better for some users. That being said, it is important to bear in mind that Apple has now moved away from Intel-based machines entirely. At some point in the future, Intel-based Macs are likely to lose support for the latest version of macOS, so if you are a user that specifically needs 2019 Mac Pro features like eGPU support or an Intel architecture, the 2019 Mac Pro may only be able to help out for so long and it may be important to look at bigger changes to support your workflow in the long term.
The 2013 Mac Pro only supports updates up to macOS 12 Monterey, meaning it misses out on all of the new features added in macOS Ventura and macOS Sonoma. Those still using the 2013 Mac Pro should definitely consider upgrading, and both the 2019 or 2023 Mac Pro models are viable options. Alternatively, if you have got used to the 2013 Mac Pro's lack of PCIe slots and reliance on wired peripherals, the Mac Studio may be a better option, starting at just $1,999.
