:description: Learn about GL2 Cache metrics in ROCm Compute Profiler, including cache performance, bandwidth, and request statistics on RDNA3.5 (gfx115x).

GL2 cache

=========
|
|
|
|
On gfx115x, GL2 cache (RDNA naming for what Instinct documentation refers to as
|
|
L2/TCC) is the last-level GFX on-chip cache for most clients before traffic reaches the memory system.
|
|
|
|
After GL2, traffic proceeds toward DRAM through GCEA and related interfaces; those panels are documented under :doc:`gcea`.
|
|
|
|
For Instinct L2 (TCC) coherence, channel hashing, and fabric metrics on CDNA
|
|
architecture-based AMD Instinct MI-Series GPUs, see :doc:`../cdna/l2-cache` under
|
|
CDNA-CDNA4.
|
|
|
|
.. note::
|
|
|
|
The GL2 Cache is also referred to as GL2C in some contexts. Hardware counter
|
|
names (for example, ``GL2C_HIT_sum``) retain the GL2C prefix.
