Apple’s Mac engineers have been on a tear in recent years, with high-performance chips appearing at every turn. That’s led to a lot of fevered speculation about what Apple is planning next, with rumors running wild about a secretive chip codenamed “Hidra” that’s reportedly in the works.
If you’ve been wondering what to expect from the Hidra chip and want to make sense of all the rumors, you’re in the right place. We’ve combed the internet for all the latest ideas and collated them here, so you can find out everything you need to know about Apple’s upcoming superpowered chip. Read on to get in the know.
Right now, the consensus seems to be that Hidra is an “Ultra” tier chip — that is, the M4 Ultra. If that’s the case, it’ll come to the Mac Studio and the Mac Pro, but don’t expect to see it anywhere else.
In previous years, these incredibly powerful Macs were the only ones to get Ultra chips — devices like the MacBook Pro and Mac mini simply don’t need that much power (and probably wouldn’t be able to cool it anyway). Given that trend, that’s almost certainly going to be the case again with the M4 Ultra.
All rumors seem to point to a launch date in 2025 for the Hidra chip. The exact date, though, depends on which Mac we’re talking about.
The Mac Studio, for instance, is expected to come first. Bloomberg reporter Mark Gurman has variously claimed that the new Mac Studio will launch between March and June 2025, in the first half of 2025, and “around the middle of the year.” Either way, it looks like it’ll be the next Mac to launch after the MacBook Air, which is coming in the spring, Gurman says.
The Mac Pro, on the other hand, should come in the second half of the year. Gurman believes that it’s “on track to be ready before the MacBook Pro, though the timing isn’t yet clear.” The MacBook Pro is often updated in the fall, so expect the Mac Pro before that.
Another possible release date for the Hidra chip is Apple’s Worldwide Developers Conference (WWDC) in June 2025. After all, Apple updated both the Mac Studio and the Mac Pro at WWDC in 2023, so it’s happened before. What’s more, WWDC is a developer event, so a big segment of both computers’ target audiences will be in attendance. Apple could perhaps tease the Hidra chip at WWDC and launch it in Macs later in the year.
Apple didn’t release an M3 Ultra chip, so when the M4 Ultra launches, it could be a major step up over the M2 Ultra that came before it. And although it’s still some way off, there are a few things we expect to see in terms of specs and performance.
According to Mark Gurman, the M4 Ultra will probably have up to a 32-core CPU and up to an 80-core GPU. For comparison, the current M2 Ultra has a 24-core CPU and can be configured to have up to a 76-core GPU.
Gurman adds that “Apple is considering allowing its highest-end Mac desktops to support as much as a half-terabyte of memory.” Outfitting the Mac Studio and Mac Pro with around 512GB of RAM would be a significant improvement over the current limit, which stands at 192GB. Yet it’s still far below the 1.5TB you could equip the Intel-based Mac Pro with.
While we can’t know for sure what sort of performance those specs will translate into, news outlet AppleInsider has extrapolated some predicted M4 Ultra results based on Apple’s previous chips.
AppleInsider noted that the M1 Ultra and M2 Ultra offered roughly 45% better performance in Geekbench’s single-core tests compared to the M1 Max and M2 Max, respectively. If that was to repeat in the M4 generation, the M4 Ultra could score around 37,315 in Geekbench’s single-core benchmark, up from the M4 Max’s 25,735 score.
Similarly, Metal scores have increased by roughly 53% when comparing the top-spec Max and Ultra chips in past generations, leading AppleInsider to predict the M4 Ultra may score around 287,096 in Metal benchmarks. That’s up from the M4 Max’s 187,645 score.
Given that these are merely extrapolations, we should take them with a pinch of salt. But they don’t sound unreasonable based on previous results, and we know that Apple will want to show off significant performance increases to spur sales of its Mac Studio and Mac Pro computers.
There’s another thing to clear up: Apple’s much-rumored ‘Extreme’ chip. This has been talked about for a few years now, with whispers previously emerging that Apple could launch an M2 Extreme chip that would take its place as the ultimate Mac chip in terms of performance — and price.
That never came to pass, and we’ve heard a lot since then. Both Mark Gurman and news site The Information have claimed to have heard from sources inside Apple that the company has ceased work on the Extreme chip. Gurman explained that the chip was too complicated and expensive to manufacture, with the resulting Mac Pro likely to cost at least $10,000 (without any upgrades), making it far too niche to be worth Apple’s time.
Writing in April 2024, Gurman said that Apple has at least three M4 chip tiers on the go: the entry-level “Donan,” which is the M4; the mid-range “Brava,” which we know is the M4 Pro since Gurman said it would be in the Mac mini, which came to pass; and the high-end “Hidra,” which must be the M4 Ultra rather than the M4 Max because Gurman said it would be in the Mac Pro, which the Max chips are not.
If there was going to be an M4 Extreme, you would imagine that Gurman’s list would cover five different tiers to account for the M4, M4 Pro, M4 Max, M4 Ultra, and M4 Extreme. Considering how significant the Extreme chip would be were it to launch as part of the M4 generation, its absence from Gurman’s account is telling.
There’s another reason to be skeptical that the Hidra chip equates to the M4 Extreme, and it’s all about the timing. We’re only a couple months away from the Mac Studio being updated, yet there’s a complete dearth of rumors claiming that it will come with the M4 Extreme. The Mac Pro is a little further out, but the case remains the same there. Usually, big news like this leaks out well in advance, so the lack of convincing rumors suggests that the M4 Extreme isn’t arriving any time soon.
Typically, Apple takes its time with big new features and wants to make sure it’s the best rather than the first, so it’s usually a good idea to expect things later rather than sooner. That’s why we still haven’t seen an OLED MacBook Pro, for example, despite OLED tech having been in many of the best laptops for years. That doesn’t mean that Apple will never launch an Extreme chip, but it feels unlikely this year. We will almost certainly see the Hidra chip, however, in the form of the M4 Ultra.
The absolutely absurd idea of putting a touchscreen display on a mouse isn't exactly new. Turtle Beach already did it with its Command Series MC7, which features a 2.25-inch control screen. But apparently, even that wasn't ridiculous enough for Arctic Fox Technologies. Its new Super Mouse looks like someone took the chunky old Atari ST mouse, slapped a touchscreen and scroll wheel on it, and called it an upgrade.
The result is a rather unusual-looking mouse that is now on Kickstarter, starting at $199. And as ridiculous as it looks, some of its features are genuinely intriguing.
Apple is less than a day away from launching its highly anticipated OLED MacBook Pro with a touch-sensitive screen. But it appears that the upgrade is going to cost a pretty penny. According to a report by Bloomberg, Apple is reportedly eyeing a starting price of $2,899 for the 14-inch MacBook Pro, while the 16-inch version could start at $3,399 in the US.
"At $2,899, the 14-inch model would mark the highest starting price for a new MacBook Pro model, surpassing the $2,799 Apple charged for a 17-inch version introduced in 2006," says the report. The report claims that Apple is targeting a minimum price hike of $400 for its upcoming redesigned 14-inch and 16-inch MacBook Pro models.
I've spent a good amount of time digging into the spec sheet of the new M6 MacBook Pro (14-inch), and for all intents and purposes, this is a classic Apple "chip and connectivity" refresh. It's not a full redesign. The chassis, Liquid Retina XDR panel, speakers, ports, and battery, all of them carry over unchanged.
However, the M6 brings more cores, stronger on-device AI, higher memory bandwidth on the larger configs, and modern wireless. Here’s the practical rundown of what actually improved, and whether those gains are worth your money.
