Shared 12 MB L2 cache

4 high-efficiency cores
128 KB instruction cache
64 KB data cache

128 execution units
Up to 24576 concurrent threads
2.6 Teraflops
82 Gigatexels/s
41 gigapixels/s

16-core neural engine

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

Apple introduces MacBook Pro with all-new M5 Pro and M5 Max

Apple announced the latest 14- and 16-inch MacBook Pro with the all-new M5 Pro and M5 Max.

www.apple.com

"The chips are built using a new Apple-designed Fusion Architecture. This innovative design combines two dies into a single system on a chip (SoC), which includes a powerful CPU, scalable GPU, Media Engine, unified memory controller, Neural Engine, and Thunderbolt 5 capabilities. M5 Pro and M5 Max feature a new 18-core CPU architecture. It includes six of the highest-performing core design, now called super cores, that are the world’s fastest CPU core.1 Alongside these cores are 12 all-new performance cores, optimized for power-efficient, multithreaded workloads. Collectively, the CPU significantly boosts performance by up to 30 percent for pro workloads.2 The GPU scales up the next-generation architecture introduced in M5 to an up-to-40-core GPU. With a Neural Accelerator in each GPU core and higher unified memory bandwidth, M5 Pro and M5 Max are over 4x the peak GPU compute for AI compared to the previous generation.2 The GPU substantially increases graphics capabilities — now up to 35 percent for apps using ray tracing than M4 Pro and M4 Max — enhancing advanced visual effects and 3D rendering."

It includes six of the highest-performing core design, now called super cores, that are the world’s fastest CPU core.1 Alongside these cores are 12 all-new performance cores, optimized for power-efficient, multithreaded workloads.

So it's basically a rename of cores, the standard P core is now super core and E core is now perf core. Or are the Perf cores something else than rebranded E cores?

Finally starts with 512 GB. I wonder what that means for the A series MacBook.

6K is now gone! Only 5K now, even for the XDR. Weird.

M5 Pro and M5 Max introduce the Apple-designed Fusion Architecture, a state-of-the-art design that connects two dies into a single SoC. This brings together two third-generation 3-nanometer dies with high bandwidth and low latency using advanced packaging. The two dies include a powerful new CPU, scalable GPU, Media Engine, unified memory controller, Neural Engine, and Thunderbolt 5 capabilities.

Nyo.
Perf cores are the equivalent of Oryon-M or Cortex-A. They're midcores basically.
Super cores are just a rebrand besides them having normal caches now (1M private L2 + shared L3).

So even the iPhone 17e has 256 GB base storage.

So I doubt the low cost Macbook will have a 128 GB option.

They should bump up the Macbook Air's base to 512 GB, and the Macbook Pro to 1 TB.

"MacBook Air now comes standard with double the starting storage at 512GB with faster SSD technology"

Yep.

Edit:

Price is $100 higher though.

M4 MBA 256 GB was $999, and 512 GB was $1199.

M5 MBA 512 GB is $1099.

[mvprod123]

M5 Pro

18-core CPU (6 super cores and 12 performance cores)
20-core GPU
307GB/s memory bandwidth (256-bit LPDDR5x-9600)

M5 Max:

18-core CPU (6 super cores and 12 performance cores)
40-core GPU
614GB/s memory bandwidth (512-bit LPDDR5x-9600)

The new MacBook Pro delivers up to 2x faster read/write performance compared to the previous generation,4 reaching speeds of up to 14.5GB/s

 

[regen1]

Yeah. They increased base storage for MacBook Pro variants as well.

"It now comes with up to 2x faster SSD performance and starts at 1TB of storage for M5 Pro and 2TB for M5 Max."

"MacBook Pro with M5 Pro now comes standard with 1TB of storage, while MacBook Pro with M5 Max now comes standard with 2TB. And the 14-inch MacBook Pro with M5 now comes standard with 1TB of storage."

M5 MBA 512 GB is $1099.

This makes a $599 retail MacBook extremely unlikely.

We do not yet know what level these new p-cores are at.

 

[Geddagod]

 

[adroc_thurston]

They're not new! M5 already has them.
Unless you mean the mediums, then they're somewhere in the ballpark of 60% perf.

Where did you read this?

I just know what I know.

M-core is more like Intel's E-core.

its new!

You mean mCores? yeah.

 

[MerryCherry]

Well, that new cache setup is big news, if true.

Edit:

Article mentions this, but no details are given.

"The industry-leading super core was first introduced as performance cores in M5, which also adopts the super core name for all M5-based products — MacBook Air, the 14-inch MacBook Pro, iPad Pro, and Apple Vision Pro. This core is the highest-performance core design with the world’s fastest single-threaded performance, driven in part by increased front-end bandwidth, a new cache hierarchy, and enhanced branch prediction."

Apple debuts M5 Pro and M5 Max to supercharge the most demanding pro workflows

Apple today announced M5 Pro and M5 Max, the world’s most advanced chips for pro laptops, powering the new MacBook Pro.

[Covfefe]

It'll be interesting to see how they split up the chiplets. M5 Pro and M5 Max have the same CPU cores, but different memory channels. I assume they want to use the same CPU chiplet for both SKUs. Are the memory controllers on the GPU chiplet?

 

[mvprod123]

Apple has improved display connectivity.

 

[poke01]

So M5 Max has 16MB of L3 cache?
