Struct DeviceInfo 

#[non_exhaustive]
pub struct DeviceInfo {
    pub name: String,
    pub architecture: String,
    pub generation: Option<u32>,
    pub class: Option<char>,
    pub recommended_working_set: u64,
    pub max_threads_per_threadgroup: usize,
    pub physical_memory: u64,
}

What the GPU is and what it can do.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

Marketing name, e.g. Apple M4 Pro.

architecture: String

Metal’s architecture string, e.g. applegpu_g16s.

generation: Option<u32>

GPU generation parsed from the architecture string (16 for applegpu_g16s), if any. Neural-accelerator kernels need generation 17 or later.

class: Option<char>

Class letter after the generation (s for applegpu_g16s), if any. Kept verbatim: the letter-to-tier mapping is not documented by Apple.

recommended_working_set: u64

Bytes the GPU can use without hurting performance.

max_threads_per_threadgroup: usize

Maximum threads per threadgroup along one dimension.

physical_memory: u64

The machine’s physical memory in bytes (unified memory: shared by the CPU and the GPU; hw.memsize, MLX’s device_info()["memory_size"]).
