+:ref:`specific documents and guides <gpu-arch-documentation>`, or 
+:doc:`Understanding the HIP programming model<hip:understand/programming_model>`.
+
+**LLVM target name**
+
+Argument to pass to clang in `--offload-arch` to compile code for the given
+architecture.
+
+**VRAM**
+
+Amount of memory available on the GPU.
+
+**Compute Units**
+
+Number of compute units on the GPU.
+
+**Wavefront Size**
+
+Amount of work items that execute in parallel on a single compute unit. This
+is equivalent to the warp size in HIP.
+
+**LDS**
+
+The Local Data Share (LDS) is a low-latency, high-bandwidth scratch pad
+memory. It is local to the compute units, and can be shared by all work items
+in a work group. In HIP, the LDS can be used for shared memory, which is
+shared by all threads in a block.
+
+**L3 Cache (CDNA/GCN only)**
+
+Size of the level 3 cache. Shared by all compute units on the same GPU. Caches
+data and instructions. Similar to the Infinity Cache on RDNA architectures.
+
+**Infinity Cache (RDNA only)**
+
+Size of the infinity cache. Shared by all compute units on the same GPU. Caches
+data and instructions. Similar to the L3 Cache on CDNA/GCN architectures.
+
+**L2 Cache**
+
+Size of the level 3 cache. Shared by all compute units on the same GCD. Caches
+data and instructions.
+
+**Graphics L1 Cache (RDNA only)**
+
+An additional cache level that only exists in RDNA architectures. Local to a
+work group processor.
+
+**L1 Vector Cache (CDNA/GCN only)**
+
+Size of the level 1 vector data cache. Local to a compute unit. This is the L0
+vector cache in RDNA architectures.
+
+**L1 Scalar Cache (CDNA/GCN only)**
+
+Size of the level 1 scalar data cache. Usually shared by several compute
+units. This is the L0 scalar cache in RDNA architectures.
+
+**L1 Instruction Cache (CDNA/GCN only)**
+
+Size of the level 1 instruction cache. Usually shared by several compute
+units. This is the L0 instruction cache in RDNA architectures.
+
+**L0 Vector Cache (RDNA only)**
+
+Size of the level 0 vector data cache. Local to a compute unit. This is the L1
+vector cache in CDNA/GCN architectures.
+
+**L0 Scalar Cache (RDNA only)**
+
+Size of the level 0 scalar data cache. Usually shared by several compute
+units. This is the L1 scalar cache in CDNA/GCN architectures.
+
+**L0 Instruction Cache (RDNA only)**
+
+Size of the level 0 instruction cache. Usually shared by several compute
+units. This is the L1 instruction cache in CDNA/GCN architectures.
+
+**VGPR File**
+
+Size of the Vector General Purpose Register (VGPR) file and. It holds data used in
+vector instructions.
+GPUs with matrix cores also have AccVGPRs, which are Accumulation General
+Purpose Vector Registers, used specifically in matrix instructions.
+
+**SGPR File**
+
+Size of the Scalar General Purpose Register (SGPR) file. Holds data used in
+scalar instructions.
+
+**GCD**
+
+Graphics Compute Die.
