The Mac Pro's memory slots can accommodate either R-DIMMs or LR-DIMMs, and, without getting into too much technical detail here, the germane difference between Registered DIMMs and Load-Reduced DIMMs is that LR-DIMMs offer higher capacities (albeit with a slight decrease in memory bandwidth). All other processors used in the new Mac Pro range support a maximum memory speed of 2933MHz. Although the memory modules supplied with the Mac Pro models are clocked at 2933MHz, the eight-core system runs this memory at a reduced speed of 2666MHz as it's the maximum speed supported by the Xeon W‑3223. When it comes to expanding the memory, the Mac Pro has a six-channel memory controller supporting 12 slots for memory, and Apple ship four 8GB modules to provide the initial 32GB.

So if you can't justify the expense of a 24-core Mac Pro, I wouldn't be too perturbed by the 'limitation' of only being able to use 768GB memory!

Consider a sample library such as Spitfire's BBC Symphony Orchestra: this has an on-disk size of 568GB, so with 768GB RAM you could load the entire library into memory (which you wouldn't need to anyway thanks to streaming from high-speed storage and microphone positions you probably don't need) and still have nearly 200GB to spare for Mac OS, applications, plug-ins and project data. However, even that capacity is impressive. Apple will charge you £9000-£12,600 $10,000-$14,000 to order 768GB in your Mac Pro depending on the capacity of the modules, and as normal, you'll be able to save a little money by ordering third-party offerings from the usual suspects. To put these figures in perspective, let's first consider cost.

The maximum amount of memory you can install into a new Mac Pro depends on which processor you opt for, with the 8-, 16- and 12-core models supporting a maximum of 768GB memory, and the 24- and 28-core processors allowing a monstrous 1.5TB. And while you're almost certainly going to require more, especially if you're running sizable sessions or projects with large numbers of virtual instruments that pre-load sampled libraries, 32GB seems like a reasonable starting point. However, to give the processor the best possible chance, Apple have given each chip a large heatsink with over 300W of cooling, even though Intel's requirements are roughly two thirds of this when these processors are operating at base frequency.Įach new Mac Pro is supplied with 32GB DD4 ECC memory. So while your mileage may vary, given that your Mac Pro's processor isn't going to maintain a sustained clock speed of 4 or 4.4 GHz if you're running all of the cores flat out with a heavy workload, Turbo Boost will provide extra performance in certain situations. Turbo Boost dynamically increases the clock speed based on circumstances predicated by demand, of course, but constrained by factors like thermal limits, how many cores are active, and so on. The eight-core processor has Turbo Boost up to 4GHz, while the other chips support Turbo Boost up to 4.4GHz. The base Mac Pro uses a Xeon W‑3223 processor with eight cores clocked at 3.5GHz, and four other processor options are available: a 3.3GHz 12-core Xeon W‑3235, a 3.2GHz 16-core Xeon W‑3245, a 2.7GHz 24-core Xeon W‑3265M, or a 2.5GHz 28-core Xeon W‑3275M. Launched in the second quarter of 2019, this is an optimised improvement over Intel's previous so-called 'Skylake' design and, while I sadly don't have space to go into all the details here, two important changes are support for 28 cores and memory capacities of 1.5TB at speeds of up to 2933MHz, as we shall see. The Workstation-class Xeon processors used inside the new Mac Pro models are based on Intel's 'Cascade Lake' micro-architecture.
