Discussion Apple Silicon SoC thread

[Eug]

M1
5 nm
Unified memory architecture - LP-DDR4
16 billion transistors

8-core CPU

4 high-performance cores
192 KB instruction cache
128 KB data cache
Shared 12 MB L2 cache

4 high-efficiency cores
128 KB instruction cache
64 KB data cache
Shared 4 MB L2 cache
(Apple claims the 4 high-effiency cores alone perform like a dual-core Intel MacBook Air)

8-core iGPU (but there is a 7-core variant, likely with one inactive core)
128 execution units
Up to 24576 concurrent threads
2.6 Teraflops
82 Gigatexels/s
41 gigapixels/s

16-core neural engine
Secure Enclave
USB 4

Products:
$999 ($899 edu) 13" MacBook Air (fanless) - 18 hour video playback battery life
$699 Mac mini (with fan)
$1299 ($1199 edu) 13" MacBook Pro (with fan) - 20 hour video playback battery life

Memory options 8 GB and 16 GB. No 32 GB option (unless you go Intel).

It should be noted that the M1 chip in these three Macs is the same (aside from GPU core number). Basically, Apple is taking the same approach which these chips as they do the iPhones and iPads. Just one SKU (excluding the X variants), which is the same across all iDevices (aside from maybe slight clock speed differences occasionally).

EDIT:



M1 Pro 8-core CPU (6+2), 14-core GPU
M1 Pro 10-core CPU (8+2), 14-core GPU
M1 Pro 10-core CPU (8+2), 16-core GPU
M1 Max 10-core CPU (8+2), 24-core GPU
M1 Max 10-core CPU (8+2), 32-core GPU

How so? There was no update on that article.
You confirm on yours?

no, I cross referenced the same apple article from March. No change regarding the 160Mhz for 5GHz

Apple Executives Are Now Reportedly Booking Extended Hotel Stays To Secure Long-Term Agreements For DRAM Supply For Up To Three Years From Samsung & SK hynix

To secure an adequate DRAM support for many years, Apple executives have reportedly booked longer durations in hotels to reach an agreement with Samsung and SK hynix

Let’s see how 2026 and 27 goes

Interesting. Chip price of A20 Pro is rumoured to be USD 280.

Apple's A20 Chip Could Be Massively More Expensive

Apple's "A20" chip designed for next year's iPhone models could be considerably more expensive, the China Times reports. The A20 chip is likely to be the first widely available 2-nanometer chip, debuting in the iPhone 18 lineup next year and forming the foundation of subsequent M6-series chips...

www.macrumors.com

And seems that the jump is about 80%, that could be justified if A20 turns to be an Octa Core?I mean going 2+6.
Also that could be used for a Mac Book with A processor in a future.

I'm not sure Apple will add another +2 E-core. But the costs are probably related to the new WMCM packaging type and the new six-channel memory bus.

That article is complete BS. They are saying that A20 costs Apple as much as Qualcomm's SoC costs third parties - after Qualcomm's mark up and patent licensing? Get real!

If N2 wafers are $30K and A20 is ~100 mm^2 then they get 600 die candidates per wafer at $50 each. After yield and packaging you have to be pretty insane to believe they'll cost Apple $280. They are about 300% above the true figure lol

I wouldn't call it cheating. Reviewers who don't know any better share misleading comparisons. That's not Apple's fault.

It’s not cheating if Apple states in their documentation it’s readings should not be compared with different devices.

It’s fine to compare Mac to Mac but not much else.

It is kind of cheating, specially Apple is not calling/pointing out on bad power measurement methodology.

Also let not forget Apple really brags about how efficient their SoC is compared to Intel/AMD/Qualcomm. So there definitely something foul.

Anyone believing CPU makers claims is bound to be disappointed and called naive.

The only thing I'm sure of is that switching from a Lenovo P1 to a 5 years old MBP M1 changed my work drastically: much faster and much longer battery life. It's obviously a combination of HW and SW, but there's almost no chance I will look back at any x86 laptop before years, no matter how much I regret Linux.

Regarding real power consumption, I think measuring that on a laptop is very difficult and error prone. For desktops, it's easier and I would only take into consideration measurements done at the wall, and would never trust software to provide me with power consumption be it on a mac or an x86 platform.

Based on what would the article imply that A19 and M5 are 2nm based ?

Where did the article simply that? I didn't see that claim made anywhere when I read it!
