Notes to financial statements [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. 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. 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 first quarters of fiscal years 2015 and 2014 are both 13-week quarters. 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. Reclassifications Certain prior fiscal year balances have been reclassified to conform to the current fiscal year presentation. 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. Revenue Recognition Product Revenue We recognize revenue from product sales when persuasive evidence of an arrangement exists, the product has been delivered, the price is fixed or determinable and collection of the related receivable is reasonably assured. For most sales, we use a binding purchase order and in certain cases we use a contractual agreement as evidence of an arrangement. We consider delivery to occur upon shipment provided title and risk of loss have passed to the customer. At the point of sale, we assess whether the arrangement fee is fixed or determinable and whether collection is reasonably assured. If we determine that collection of a fee is not reasonably assured, we defer the fee and recognize revenue at the time collection becomes reasonably assured, which is generally upon receipt of payment. Our policy on sales to certain distributors with rights of return is to defer recognition of revenue and related cost of revenue until the distributors resell the product, as the level of returns cannot be reasonably estimated. Our customer programs primarily involve rebates, which are designed to serve as sales incentives to resellers of our products in various target markets. We account for rebates as a reduction of revenue and accrue for 100% of the potential rebates and do not apply a breakage factor. While we have a long history of rebate arrangements with original equipment manufacturers, or OEMs, we believe we are unable to apply our historical experience to reliably estimate the amount of rebates that will eventually be claimed by individual OEMs. The OEMs are not our direct customers and the quantity and mix of demand they place on contract equipment manufacturers and original design manufacturers may shift as we introduce new generations and iterations of products and as we experience changes in new competitor offerings. In addition, we typically find that approximately 95% of the rebates we accrue each year are eventually claimed, which is substantially close to 100%, and that this percentage varies by program and by customer. We recognize a liability for these rebates at the later of the date at which we record the related revenue or the date at which we offer the rebate. Rebates typically expire six months from the date of the original sale, unless we reasonably believe that the customer intends to claim the rebate. Unclaimed rebates are reversed to revenue, the amount of which typically represents approximately 0.5% of total revenue. Our customer programs also include marketing development funds, or MDFs. MDFs represent monies paid to retailers, system builders, OEMs, distributors and add-in card partners that are earmarked for market segment development and expansion and typically are designed to support our partners’ activities while also promoting NVIDIA products. Depending on market conditions, we may take actions to increase amounts offered under customer programs, possibly resulting in an incremental reduction of revenue at the time such programs are offered. We account for MDFs as a reduction of revenue and apply a breakage factor to certain types of MDF program accruals for which we believe we can make a reasonable and reliable estimate of the amount that will ultimately be unclaimed. MDF amounts that have been previously recorded against revenue and subsequently expired unclaimed are reversed to revenue. Such amounts have not been significant. We also record a reduction to revenue by establishing a sales return allowance for estimated product returns at the time revenue is recognized, based primarily on historical return rates. However, if product returns for a particular fiscal period exceed historical return rates we may determine that additional sales return allowances are required to properly reflect our estimated exposure for product returns. License and Development Revenue For license arrangements that require significant customization of our intellectual property components, we generally recognize the related revenue over the period that services are performed. For most license and service arrangements, we determine progress to completion based on actual direct labor hours incurred to date as a percentage of the estimated total direct labor hours required to complete the project. We periodically evaluate the actual status of each project to ensure that the estimates to complete each contract remain accurate. A provision for estimated losses on contracts is made in the period in which the loss becomes probable and can be reasonably estimated. Costs incurred in advance of revenue recognized are recorded as deferred costs on uncompleted contracts. If the amount billed exceeds the amount of revenue recognized, the excess amount is recorded as deferred revenue. Revenue recognized in any period is dependent on our progress toward completion of projects in progress. Significant management judgment and discretion are used to estimate total direct labor hours. Any changes in or deviations from these estimates could have a material effect on the amount of revenue we recognize in any period. For license arrangements that do not require significant customization but where we are obligated to provide further deliverables over the term of the license agreement, we record revenue over the life of the license term, with consideration received in advance of the performance period classified as deferred revenue. Royalty revenue is recognized related to the distribution or sale of products that use our technologies under license agreements with third parties. We recognize royalty revenue upon receipt of a confirmation of earned royalties and when collectability is reasonably assured from the applicable licensee. Inventories Inventory cost is computed on an adjusted standard basis, which approximates actual cost on an average or first-in, first-out basis. Inventory costs consist primarily of the cost of semiconductors purchased from subcontractors, including wafer fabrication, assembly, testing and packaging, manufacturing support costs, including labor and overhead associated with such purchases, final test yield fallout, and shipping costs, as well as the cost of purchased memory products and other component parts. We charge cost of sales for inventory provisions to write down our inventory to the lower of cost or estimated market value or to completely write off obsolete or excess inventory. Most of our inventory provisions relate to the write-off of excess quantities of products, based on our inventory levels and future product purchase commitments compared to assumptions about future demand and market conditions. Once inventory has been written-off or written-down, it creates a new cost basis for the inventory that is not subsequently written-up. Net Income Per Share Basic net income per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted average number of common and potentially dilutive shares outstanding during the period, using the treasury stock method. Under the treasury stock method, the effect of stock options outstanding is not included in the computation of diluted net income per share for periods when their effect is anti-dilutive. Additionally, we issued convertible notes with a net settlement feature that requires us, upon conversion, to settle the principal amount of debt for cash and the conversion premium for cash or shares of our common stock. Our convertible notes, note hedges, and related warrants contain various conversion features, which are further described in Note 11 of these Notes to Condensed Consolidated Financial Statements. The potentially dilutive impact of the convertible notes and warrants under the treasury stock method will be included in the calculation of diluted shares when their conversion features are exercisable. However, unless actually exercised, the note hedges will not be included in the calculation of diluted shares, as their pre-exercised effect would be anti-dilutive under the treasury stock method. Adoption of New and Recently Issued Accounting Pronouncements In July 2013, the Financial Accounting Standards Board issued updated guidance regarding the presentation of unrecognized tax benefits when a net operating loss carry forward, similar tax loss, or tax credit carry forward exists. The guidance requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry forward, a similar tax loss, or a tax credit carry forward when settlement in this manner is available under the tax law. We adopted this guidance in our interim period ended April 27, 2014. The adoption of this guidance did not impact our condensed consolidated financial statements, as the guidance was issued to reduce diversity in practice on presentation of unrecognized tax benefits.

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.

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 first quarters of fiscal years 2015 and 2014 are both 13-week quarters.

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.

Reclassifications

Certain prior fiscal year balances have been reclassified to conform to the current fiscal year presentation.

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.

For most sales, we use a binding purchase order and in certain cases we use a contractual agreement as evidence of an arrangement.

For license arrangements that do not require significant customization but where we are obligated to provide further deliverables over the term of the license agreement, we record revenue over the life of the license term, with consideration received in advance of the performance period classified as deferred revenue.

Royalty revenue is recognized related to the distribution or sale of products that use our technologies under license agreements with third parties. We recognize royalty revenue upon receipt of a confirmation of earned royalties and when collectability is reasonably assured from the applicable licensee.

Inventories

Inventory cost is computed on an adjusted standard basis, which approximates actual cost on an average or first-in, first-out basis. Inventory costs consist primarily of the cost of semiconductors purchased from subcontractors, including wafer fabrication, assembly, testing and packaging, manufacturing support costs, including labor and overhead associated with such purchases, final test yield fallout, and shipping costs, as well as the cost of purchased memory products and other component parts.

In July 2013, the Financial Accounting Standards Board issued updated guidance regarding the presentation of unrecognized tax benefits when a net operating loss carry forward, similar tax loss, or tax credit carry forward exists. The guidance requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry forward, a similar tax loss, or a tax credit carry forward when settlement in this manner is available under the tax law. We adopted this guidance in our interim period ended April 27, 2014.
