**Device major version**
Indicates the core instruction set of the GPU architecture. For example, a value
of 11 would correspond to Navi III (RDNA3).
**Device minor version**
Indicates a particular configuration, feature set, or variation within the group
represented by the device compute version. For example, different models within
the same major version might have varying levels of support for certain features
or optimizations.
**VRAM**
Amount of memory available on the GPU.

**GFXIP**
GFXIP (Graphics IP) is a versioning system used by AMD to identify the GPU
architecture and its instruction set. It helps categorize different generations
of GPUs and their feature sets.
**GFXIP major version**
Defines the GPU's core instruction set and architecture, which determines
compatibility with software stacks such as HIP and OpenCL. For example, a GFXIP
11 major version corresponds to the RDNA 3 (Navi 3x) architecture, influencing
driver support and available compute features.
**GFXIP minor version**
Represents specific variations within a GFXIP major version and affects feature sets,
optimizations, and driver behavior in software stacks such as HIP and OpenCL. Different
GPU models within the same major version can have unique capabilities, impacting
performance and supported instructions.
**GCD**
Graphics Compute Die.
