Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies 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 26, 2020 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 26, 2020, 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 26, 2020. Significant Accounting Policies There have been no material changes to our significant accounting policies in Note 1 - Organization and Summary of Significant Accounting Policies, of the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended January 26, 2020. Fiscal Year We operate on a 52- or 53-week year, ending on the last Sunday in January. Fiscal year 2021 is a 53-week year and fiscal year 2020 is a 52-week year. The first quarters of fiscal years 2021 and 2020 were both 13-week quarters. Reclassifications Certain prior fiscal year balances have been reclassified to conform to the current fiscal year presentation. 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 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 on-going 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 on our critical and significant accounting estimates. These estimates are based on historical facts and various other assumptions that we believe are reasonable. Adoption of New and Recently Issued Accounting Pronouncements Recently Adopted Accounting Pronouncement In June 2016, the Financial Accounting Standards Board issued a new accounting standard to replace the existing incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates for accounts receivable and other financial instruments, including available-for-sale debt securities. The Company adopted the standard in the first quarter of fiscal year 2021 and the impact of the adoption was not material to the Company's consolidated financial statements.
