Notes to financial statements [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. In the opinion of management, all adjustments, consisting only of normal recurring adjustments except as otherwise noted, 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 financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended January 26, 2014. Significant Accounting Policies For a description of significant accounting policies, see 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, 2014. There have been no material changes to our significant accounting policies since the filing of the Annual Report on Form 10-K.
New Accounting Pronouncements	Adoption of New and Recently Issued Accounting Pronouncements In August 2014, the Financial Accounting Standards Board, or FASB, issued new guidance related to our responsibility to evaluate whether there is substantial doubt about our ability to continue ongoing business operations and to provide relevant footnote disclosures. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our financial statements. In June 2014, the FASB issued new guidance related to stock-based compensation. The new guidance requires that a performance target that affects vesting, and that could be achieved after the requisite service period is rendered, be treated as a performance condition. The new guidance is effective for interim periods within and those fiscal years, beginning after December 15, 2015. We currently do not have awards with a performance target where the employee would be eligible to vest in the award regardless of whether the employee is rendering service on the date the performance target is achieved. Therefore, we believe, the adoption of this new accounting guidance will not have an impact on our consolidated financial statements. In May 2014, the FASB issued a new accounting standard update that creates a single source of revenue guidance under U.S. GAAP for all companies, in all industries. Under the new standard, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the new guidance requires that reporting companies disclose the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including significant judgments and estimates used. This new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. We will adopt this guidance either by using a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. We are currently evaluating the impact of this accounting guidance on our consolidated financial statements and have not yet determined which transition method we will apply.
Fiscal Period, Policy [Policy Text Block]	Fiscal Year We operate on a 52- or 53-week year, ending on the last Sunday in January. Fiscal year 2015 and fiscal year 2014 are both 52-week years. The third quarters of fiscal years 2015 and 2014 are both 13-week quarters.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation Our condensed consolidated financial statements include the accounts of NVIDIA Corporation and its wholly-owned subsidiaries. All material inter-company balances and transactions have been eliminated in consolidation.
Reclassification, Policy [Policy Text Block]	Reclassifications Certain prior fiscal year balances have been reclassified to conform to the current fiscal year presentation.
Use of Estimates, Policy [Policy Text Block]	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 from those 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, warranty liabilities, litigation, investigation and settlement costs and other contingencies. These estimates are based on historical facts and various other assumptions that we believe are reasonable.

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.
