Die to die 'ultrafusion'

Users silicon interposer. Twice the density of anything in the industry.

10000 links, 2.5 TB/s
4x bandwdith of leading edge

114 billion transistors

800 GB/s DRAM bandwidth, 128 GB of unified memory

16 performance cores, 4 efficient cores

64-core GPU

Overall

@dylan522p any idea what silicon interposer is being used?

One of the big things with M1 Ultra is going to be that GPU with 800 GB/s of bandwidth. Assuming the GPUs on each die can work collectively on a single task.

Actually, that's really important - can the GPUs work on a single task together? or is it an Xe Link scenario?

800GB/s is also not the real story. A single core can barely access 200 GB/s, so it's a collective effort to use that bandwidth

Announcing Mac Studio

The small one is Mac Studio. There's also Mac Studio display.

Guessing on price, Mac Studio probably starts at $4k ? More?

Single aluminium extrusion -
3.7-inch by 7.7-inch by 7.7-inch

Double sided blower
Custom circular power supply
Low impedance heatsink
'Barely hear it' for most workloads

4 x TB ports
10 GbE RJ45
2 x Type-A
HDMI
2 x TB4 / Type-C 10 Gbps on front
SDXC port
Supports high impedance
Supports 5 x 4K displays

CPU Performance

GPU Performance

Exact benchmarks likely to be on the website later

More CPU

More GPU

128 GB unified memory for GPU.

This'll be good for ML

8 TB of 7.4 GB/s SSD performance

No way to add extra though except through TB4 ports

The specifications seem great.

The problem is that to take these pictures and do this tweet stream, I'm using custom scripts I've written using software that has no Mac counterpart.

and FWIW, this looks like a system crashed during Johny's section

I don't know what this means

Final specifications

Studio Display time.

Tilt and Vesa require a different stand. to buy

600 nits
5K retina, 14.7 MP
10-bit native
27-inch
Nano-texture option to minimize glare

Has A13 Bionic inside

Comes with 12MP camera
3 mic array
six speakers for spatial audio

looks like two fans as well?
Does the A13 do noise cancellation?

3 x 10 Gbps USB-C
1 x TB port, 96W power from monitor

Really needs two TB ports for daisy chain

Sustainability

Pairs with an Mac

Spot the socket

as @bmastenbrook said, if there's an A13 inside the display, where's the apple tv+ support?

@bmastenbrook M1 Ultra Mac Studio starts at $3999.

CALLED IT

Studio Display at $1599

@bmastenbrook March 18th

And that's a wrap.

I've already seen a request for me to review it. I have zero contacts with Apple.
