Question

How much VRAM does the M1 Chip have? How does this work?

In traditional computer layouts you have a CPU with an Integrated GPU that has a small amount of VRAM, and then some computers also have a Dedicated GPU with way more VRAM.

In comparison, how does this compare to the M1 chip in terms of specs for VRAM of the GPU? I can't find specs for this. I just want a side by size spec comparison and can't seem to find one.

EX:

(Integrated) - Intel UHD Graphics 630 1.5GB

(Dedicated) - AMD Radeon Pro 5500M 4GB of GDDR6 memory

(M1 GPU) - VRAM ????? Memory type ?????

Yeah thanks, though I already learned from another article I read a week after I posted, that the unified architecture Technology is a new ball game compared to how traditional views on look at a computers CPU and GPU. The CPU and GPU are one, and the GPU in this case actually shares the ram that is in the CPU chip itself. so until apple makes there own custom dedicated GPU the integrated GPU shares the chips ram which is automatically allocated.

in case your interested here is the article I read :)

it does indeed use ram for the gpu memory but not all 8gb i guess. i randomly came across this info while in indesign's gpu settings. so i guess it has about 5.5gb of "vram".

Since the M1 GPU is integrated into the motherboard the vram isn't defined. I found this review of the GPU: Apple M1 GPU GPU - Benchmarks and Specs ..

Also do a Google search for "M1 GPU specs" and you'll get a lot more info.
