Why would you expect Apple to first put M3 into a 15" MBA or Mac Minis when the M2 by now has evolved to higher yields and be more cost-effective? Certainly neither the low end laptops nor low end desktops need the very latest (therefore low yields and pricey) M3 chips to provide low end performance.
Low end pricing screams for M2, not for M3.
Completely agree. There's a reason Apple has moved their "latest and greatest" A-series SoCs to the iPhone Pro models only; they've become increasingly more expensive to produce. So if there is in fact a Mac-based ASi chip being produced alongside the A17, on TSMC's N3 node, to be released by or at WWDC, it will be destined for a low-volume, high-margin product. Otherwise, any M3's currently being produced won't debut until the Fall.
I also just can't see Apple releasing the base M3 so soon after the M2. I know the Mac is a different product than the iPhone, but it hasn't even been a year since the M2 was released. Furthermore, the iMac is still on the M1! It's been two years since it was released, why has no one talked about its imminent update?
Also, regarding the "Mx Extreme" being cancelled... Gurman's (who started the "quad" rumor to begin with) reasoning is because...
Based on Apple's current pricing structure, an M2 Extreme version of a Mac Pro would probably cost at least $10,000 — without any other upgrades — making it an extraordinarily niche product that likely isn't worth the development costs, engineering resources and production bandwidth it would require
Which makes zero sense, since the
highest end Intel Xeon - without any other upgrades -
starts at $12,999 Furthermore, the Mac Pro itself, is an extraordinarily niche product which is why it is so damned expensive. And what other system other than a Mac Pro could ever support an SoC the size of an "Extreme"? It was always going to be an
extraordinarily niche product. This "cancelled" rumor is just a rumormonger trying to save face.
Personally, I don't think the "quad" variant was ever in Apple's sites. It was a rumor based on an interposer schematic. The Mx Max has a single interposer connection on the bottom, so that two can "butt" up to each other. There's no evidence that they can also be "attached" side by side.
So, I still believe the delay with the Mac Pro, is in designing and producing a completely custom CPU and GPU for it. That delay mostly falling on the GPU and adding ray tracing support, so that it can truly
compete with AMD and Nvidia.
