Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill During the first quarter of fiscal year 2021, we changed our operating segments to Graphics and Compute & Networking, as discussed in Note 15 of these Notes to Condensed Consolidated Financial Statements. As a result, our reporting units also changed, and we have reassigned the goodwill balance to the new reporting units based on their relative fair values. We determined there was no goodwill impairment immediately prior to the reorganization. As of April 26, 2020, the total carrying amount of goodwill was $628 million and the amount of goodwill allocated to our Graphics and Compute & Networking reporting units were $347 million and $281 million, respectively. In the first quarter of fiscal year 2021, goodwill increased by $10 million related to acquisition activity.
