The test is completely bogus. (In reply to Chris Wilson from comment #3) > Why would you expect the GPU to run at maximum frequency? The test is > completely bogus. Hello Chris, We expect GPU frequency can increase to the supported maximum frequency when there is heavy GPU workload, which is benefit for good performance, but it seems turbo fails now. Pls tell us if we are wrong here. Close it according to Daniel's suggestion. Closing old verified. |
