- A Mac Pro has again been rumored for launch later this year
- It’ll come with an M4 Ultra based on clues drawn from Apple’s internal code
- M4 UItra could run with a 32-core CPU and an 80-core GPU in theory
The next iteration of the Mac Pro might see Apple powering the computer with an M4 Ultra chip, we’ve heard again.
It’s been a couple of years since the last incarnation of the Mac Pro, which used the M2 Ultra, so it would be a considerable leap in performance to upgrade to a theoretical M4 Ultra – but Macworld reports that this is what’s in the cards.
This is based on Apple’s internal code that Macworld caught a glimpse of somehow, which contained the identifier ‘t8152’ – and we’re told this suggests the use of the M4 Ultra, codenamed ‘Hidra’ (a name that’s previously been aired on the rumor mill via Bloomberg).

There’s not much else to this rumor, and Macworld doesn’t have any details on the spec, although it theorizes that the M4 Ultra could run with a 32-core CPU and an 80-core GPU.
As ever with this kind of leak, it could be genuine and yet never come to fruition. It might just show us that Apple has been testing a Mac Pro configuration along these lines – but it’s possible that this machine may never see the light of day, ending up canned at some point in prototyping.

Analysis: M4 or wait for M5?
This leak tells us a couple of things. Firstly, that Apple staff can’t spell ‘Hydra’ (well, okay, alternatively let’s say Apple engineers can’t think up decent codenames). And, being serious, that it does appear increasingly likely that a new Mac Pro design is going to pitch up later this year.
Indeed, the Mac Pro coming out later in 2025, complete with M4 Ultra, was suggested over a year ago now, so this latest nugget of speculation backs up the previous buzz on the grapevine.
On top of the weight of rumors starting to add up, there’s also the fact that for Apple, the Mac Pro is in something of an odd predicament right now. This is due to the M4 Pro flexing some considerable performance muscles, and outgunning the Mac Pro’s M2 Ultra. The upshot is you can buy a Mac mini (with M4 Pro) and get better performance – at least in terms of raw CPU power – than the Mac Pro, which isn’t a good look for the seriously pricey computer.
Not that the Mac Pro is competing with Apple’s compact Mac mini, of course – it’s a heavyweight pro-targeted PC that offers a lot of advantages in terms of hefty memory loadouts and PCIe expansion options. It is a very different beast indeed, but still, Apple needs to keep the Mac Pro on a reasonable footing in relative performance terms – again meaning that the rumored refresh with an M4 Ultra seems more likely.
A two-year gap also seems a fair enough timeframe for a refresh, and it feels somewhat unlikely to me that Apple would want to wait until the M5 series before pushing out a new Mac Pro given the above reasons.
That said, there are those who’ve argued that the M4 Ultra isn’t going to happen – due to issues around jamming two M4 Max chips together, which is what the Ultra chips do – and that Apple will indeed wait it out for the M5 series to make another Ultra model.
So, everything’s rather up in the air for now – but if an M4 Ultra is going to happen, it will surely be in a new Mac Pro, and we’re likely to see more leaks soon enough. If the whispers go quiet over the next couple of months, that’ll tell its own story.
