Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Securities and Exchange Commission, or SEC, Regulation S-X. The January 31, 2021 consolidated balance sheet was derived from our audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended January 31, 2021, as filed with the SEC, but does not include all disclosures required by U.S. GAAP. In the opinion of management, all adjustments, consisting only of normal recurring adjustments considered necessary for a fair statement of results of operations and financial position, have been included. The results for the interim periods presented are not necessarily indicative of the results expected for any future period. The following information should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended January 31, 2021. On May 21, 2021, our Board of Directors declared a four-for-one split of our common stock in the form of a stock dividend, or the Stock Split, which was conditioned upon obtaining stockholder approval to increase the number of our authorized shares of common stock from 2 billion to 4 billion. On June 3, 2021, at the 2021 Annual Meeting of Stockholders, our stockholders approved the amendment to our Amended and Restated Certificate of Incorporation to increase the number of authorized shares of common stock to 4 billion. As a result, each stockholder of record at the close of business on June 21, 2021 received a dividend of three additional shares of common stock for every share held on the record date, distributed after the close of trading on July 19, 2021. All share, equity award, and per share amounts and related shareholders' equity balances presented herein have been retroactively adjusted to reflect the Stock Split.
Fiscal Year	Fiscal Year We operate on a 52- or 53-week year, ending on the last Sunday in January. Fiscal year 2022 is a 52-week year and fiscal year 2021 was a 53-week year. The second quarters of fiscal years 2022 and 2021 were both 13-week quarters.
Reclassifications	Reclassifications Certain prior fiscal year balances have been reclassified to conform to the current fiscal year presentation.
Principles of Consolidation	Principles of Consolidation Our condensed consolidated financial statements include the accounts of NVIDIA Corporation and our wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from our estimates. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, cash equivalents and marketable securities, accounts receivable, inventories, income taxes, goodwill, stock-based compensation, litigation, investigation and settlement costs, restructuring and other charges, and other contingencies. The inputs into our judgments and estimates consider the economic implications of COVID-19. These estimates are based on historical facts and various other assumptions that we believe are reasonable.
