Blender Begins Testing Metal GPU Rendering on M1 Macs

I’m so happy to read this, not only because it’s another big software on it’s way to run natively on the Apple Silicon macs, but also because Blender is becoming a big actor on the animation scene (I could say one of the most important softwares in 3D)... and it is open source!!! And I love open source software.

PS: This means support for Intel macs as well, because we’re talking about the graphics API, which is shared among all macs

This is actually an area where Apples unified memory can show major advantages over a traditional GPU. GPU rendering often requires a high amount of VRAM and nowadays 4K textures and digital scans are becoming more of a norm especially when rendering for photorealistic projects like architecture.

There’s also the benefit of thermals. On a regular PC and especially in the laptop space, powerful GPUs generate a lot of heat which then causes major throttling. The M1 chips stay cool which allows for peak performance for much longer.

Very nice! Glad to see this

$1200 Lenovo Legion Slim 7 with 3060 at 70W is 2.6x ('https://forums.macrumors.com/threads/3d-rendering-on-apple-silicon-cpu-gpu.2269416/post-30676733') faster on BMW render than $3K+ MBP M1 Max. Desktop RTX is even faster at <10s.

16.39s - 3060 70W mobile (OptiX Blender 3.0)
20.57s - reference 6900xt (HIP Blender 3.0)
29s - 2070 Super (OptiX)
31s - 3060 70W mobile (OptiX Blender 2.93)
42.79s - M1 Max 32GPU (Metal supported Blender 3.1 alpha)
48s - M1 Max 24GPU (Metal Blender 3.1 alpha + patch)
51s - 2070 Super (CUDA)
1:18.34m - M1 Pro 16GPU (Metal Blender 3.1 alpha + patch)
2.04m - Mac Mini M1 (Metal Blender 3.1 alpha + patch)
2:48.03m - MBA M1 (Metal supported Blender 3.1 alpha)
3:55.81m - AMD 5800H base clock no-boost and no-PBO overclock (CPU Blender 3.0)
5:51.06m - MBA M1 (CPU Blender 3.0)

all fine and good of course, but isn't this why they are developing native software? So you were not expecting these results?

Once stable this will be a game changer.
Some of the time improvements are insane already.

I don't think that's true. As I understand it, they've already abstracted out the draw components of the GUI as an API with 3.0. A new back-end wouldn't be instant, but it won't be greater than the Cycles Metal work and can leverage what they've learned.

I just found this note:

"- As part of their Viewport efforts, Blender 3.x will be working to "move Blender to entirely use the Vulkan open standard". A Vulkan back-end is being developed along with an Apple Metal back-end. They intend to replace Blender's OpenGL back-end by end of 2022."

Thank goodness...end of 2022 can't come fast enough.
