This chip is going to give us surprises in the next future. I can only imagine what is is store, but a rack of this kind of tech could really drive down power consumption of data centers

Apple aren't making nor selling datacenter chips. They have zero interest in doing that.

Considering M1 only uses 20W max, you could add a lot of cores without any efficency savings and still be within the current Xeon 200W TDP envolope. Indeed 8 M1s to make 32perf/32efficency would only be 160W. I'm aware this is very rough, but I also imagine even 8 M1s are a fraction of the cost of one Intel Xeon W chip, so much more margin for Apple. Not good times for Intel.

Cores aren't the real picture here. AMD's high-end cores have a quarter-gig of cache. That uses a lot of power no matter how you slice it. AMD's Infinity Fabric interconnect uses 30-50% of total chip power. Apple will have similar communications overhead too. Adding more memory lanes increases power consumption as does adding more PCIe lanes and other IO. It definitely remains to be seen if their chips are significan…

It would use less if it was on the same process node as the rest of stuff though. They were fulfilling some obligation to Global Foundries by having them separately manufacture it.

"Company developing Mac Pro desktop with 40 cores, new Mac mini" It will be interesting to see how close the rumors are to fact when real hardware announcements happen. Given how fast the M1 in the MacBook Air is performing for tasks like video editing I wonder if they will really need to push to such extremes as putting 40 cores in a Mac Pro -- unless they plan to edit four 8K streams at once?

That's what a Mac Pro is for: it has always been "too much" for us, but useful for some. To give some perspective: the current version can go up to 28 Xeon W cores, 1.5TB or RAM, Radeon Pro Vega II Duo with 2 x 32 GB, ...

~$53,000 USD for the tower for those wondering

(~$54,000 USD with wheels)

I'm going to show my ignorance here, but how do they handle memory coherence in a CPU like that?

It's complicated and MESI[0]. [0] https://en.wikipedia.org/wiki/MESI_protocol

Very interesting and made me chuckle. Thank you.

Really would like to know more about the GPU and Ram. At 128 gpu cores vs the 8 in the M1 you talking 16 times the potential GPU power which could put it up there near the top of discrete GPU's.

It takes a lot to scale a GPU up that far. Memory throughput requirements (the actually expensive part) increase linearly with number of cores. It will either cost a large fortune and use a Lot of power or be memory throughput starved (and cost a small fortune).

>> Apple Inc. is preparing to release several new Mac laptops and desktops with faster processors, new designs and improved connectivity to external devices, accelerating the company’s effort to replace Intel Corp. chips and leapfrog rival PC makers.

How would they do that if there are no ports on the new devices? Seriously though, I do not buy devices without HDMI and UTP port. Dell is pretty generous with the ports and 5300 is pretty amazing. I wish Apple had some sanity in the team that decides what ports go on devices.

Insane. That's nearly the price of a DGX station.

> Apple plans to launch the redesigned MacBook Pros in 14-inch and 16-inch screen sizes. They’ll have a redesigned chassis, magnetic MagSafe charger and more ports for connecting external drives and devices. Apple is also bringing back the HDMI port and SD card slot, which it nixed in previous versions, sparking criticism from photographers and the like. Even if they continue to force the anti-feature that is the Tou…

Is Apple even going to refresh any of its Mac products with Intel CPUs at this point?

When they first announced the transition last year, it was implied that some products will still get refreshed during the 2-year transition period. But based on this article and common sense, there is minimal incentive to do an Intel refresh. Refreshing both discourages buying of Apple silicon-powered Macs and lessens the performance jump that Apple is so eager to publicize.

For example, Tiger Lake H-series was just announced/released and it'd logically target the Macbook Pro 16.

I've had MacBooks since 2005, and I'm an amateur photographer. I really don't miss the ports or MagSafe at all. I actually like the USB charging better, as it allows you to connect the cord to either side, and it doesn't get accidentally knocked out if I use it on my lap. I've found that the cord being on other side is nearly as good as magsafe anyway, as it will be better positioned to pull out if it gets yanked. Ye…

> I actually like the USB charging better, as it allows you to connect the cord to either side, and it doesn't get accidentally knocked out if I use it on my lap. I felt the same until my cat pulled my laptop off my desk by the cord. It landed on the corner with the USB plugged in, destroying the port on the laptop itself. Probably knocked a few hundred off the resale value. The little shit.

Maybe the difference is that I'm not often using the laptop with the cord strung out around animals (not that there is anything wrong with doing that). For me, at home where I have a dog and several small children, the laptop is usually on the dock. The same is true at work. When on the go, I don't usually have the dog/small children.
