The GPUSupportedLimits object for the current adapter is accessed via the Adapter.limits property.
You should note that, rather than reporting the exact limits of each GPU, browsers will likely report different tier values of different limits to reduce the unique information available to drive-by fingerprinting. For example, the tiers of a certain limit might be 2048, 8192, and 32768. If your GPU's actual limit is 16384, the browser will still report 8192.
Given that different browsers will handle this differently and the tier values may change over time, it is hard to provide an accurate account of what limit values to expect — thorough testing is advised.
Instance properties The following limits are represented by properties in a GPUSupportedLimits object. See the Limits section of the specification for detailed descriptions of what the limits relate to.
