Dell vs Supermicro: Head-to-Head on AI Server Revenue, Margins, and Backlog

Data as of: Q4 Calendar 2025 (Dell FY2026 Q4 ending Jan 2026; SMCI FY2026 Q2 ending Dec 2025)

Overview

The AI server market is producing two starkly different business models. Dell Technologies (DELL) and Super Micro Computer (SMCI) are both riding the same GPU infrastructure wave, but their latest quarters reveal a widening gap in profitability even as Supermicro closes the revenue gap at breakneck speed. Dell posted $33.4 billion in quarterly revenue with a 19.8% gross margin, while SMCI hit a record $12.7 billion at just 6.3% gross margin — raising the fundamental question of whether growth or margin durability wins in this cycle.

The Comparison

Revenue and Growth

Dell remains the larger business by a factor of four, but Supermicro is growing more than three times faster on a quarterly YoY basis. SMCI's $12.7 billion Q2 was a company record and more than doubled the year-ago quarter. Dell's 40% growth was powered by its Infrastructure Solutions Group (ISG), which posted a record $19.6 billion in revenue, up 73% YoY.

The trajectory matters: SMCI guided Q3 FY26 revenue of at least $12.3 billion and raised its full-year outlook to at least $40 billion, implying a roughly $40–45 billion annualized run rate. Dell is guiding FY27 (ending Jan 2027) to $138–142 billion, with $50 billion in AI revenue alone — roughly 100% YoY AI growth.

Profitability

This is where Dell's structural advantage is most visible. Dell's gross margin of 19.8% is more than triple SMCI's 6.3%, and that gap has been persistent. Dell's diversified revenue mix — storage, PCs, services — provides a margin cushion that a pure-play server assembler cannot match. Dell earned $2.26 billion in net income on its latest quarter versus $401 million for SMCI, despite SMCI growing far faster.

SMCI guided for gross margins to improve 30 basis points sequentially from Q2 FY26 levels, suggesting management sees a trough but not a major recovery. The company's margin compression from 13.1% (FY2025 Q1) to 6.3% reflects aggressive pricing to win hyperscale deals and a shift toward lower-margin direct liquid cooling (DLC) rack-scale solutions.

Cash Flow and Balance Sheet

Dell generated $3.95 billion in free cash flow in a single quarter. SMCI burned cash, posting -$45 million in FCF as inventory ballooned to $10.6 billion — nearly matching Dell's $10.4 billion on a fraction of the revenue base. SMCI's inventory-to-revenue ratio is roughly 3.4x Dell's, reflecting either aggressive pre-buying of GPU components or potential demand timing risk.

Dell carries significantly more debt ($31.5B), but its FCF generation comfortably services it. SMCI's $4.9 billion in debt is lower in absolute terms but more concerning given negative cash flow quarters.

AI Backlog and Order Momentum

Dell disclosed $34.1 billion in AI server orders during Q4 alone, with $9.5 billion shipped and a record $43 billion AI backlog exiting the quarter — up from $18.4 billion just one quarter prior. This 134% sequential backlog increase signals accelerating demand and provides exceptional revenue visibility.

SMCI has not disclosed comparable backlog figures, but its revenue guidance implies strong order momentum. The company's Q3 FY26 guide of at least $12.3 billion suggests demand remains robust, though without explicit backlog disclosure, investors have less visibility into durability.

Valuation

Dell trades at a slight premium on EV/Sales (1.05x vs 0.71x) but is cheaper on P/E, both trailing and forward. On a forward P/E basis, the two are nearly identical at ~13x, despite Dell's far superior margin profile. SMCI's lower EV/Sales reflects its compressed margins — investors are paying less per dollar of revenue because each dollar generates far less profit.

Key Takeaways

1. Dell wins on profitability and cash generation. A 19.8% gross margin versus 6.3%, plus $4 billion in quarterly FCF versus cash burn, gives Dell a fundamentally stronger financial profile.

2. SMCI wins on growth velocity. At +123% YoY revenue growth and a raised $40B+ full-year guide, SMCI is capturing hyperscale AI demand at a pace Dell's larger base cannot match percentage-wise.

3. Dell's $43B AI backlog is a game-changer. This is the single most important data point in the comparison — it provides 2+ quarters of AI revenue visibility and suggests Dell is becoming the preferred enterprise AI infrastructure vendor.

4. SMCI's margin trajectory is the key risk. Gross margins falling from 13% to 6% in four quarters raises questions about pricing power and whether growth is coming at the expense of long-term profitability.

Investment Implications

Who to Own

Dell is the higher-conviction holding. The combination of $43 billion in AI backlog, 20% gross margins, $8.5 billion in TTM free cash flow, and a 12.8x forward P/E offers a rare blend of growth and value. The FY27 guide of $138–142 billion (up 23% at midpoint) with $50 billion in AI revenue provides a clear growth path without margin sacrifice.

Who to Watch

SMCI offers higher upside if margins stabilize. The 30bps sequential improvement guided for Q3 could signal a trough. At 13.1x forward P/E with 64% forward revenue growth, the PEG ratio is attractive — but only if gross margins recover toward double digits. The lack of backlog disclosure and recent accounting concerns add risk premiums that Dell does not carry.

What to Watch

• SMCI's Q3 FY26 results (expected May 2026): Gross margin trajectory is the single most important variable. A move above 7% would signal stabilization.
• Dell's Q1 FY27 results: Whether the $43B AI backlog converts to revenue at guided rates.
• GPU pricing dynamics: Both companies' margins are sensitive to NVIDIA's pricing for Blackwell and successor architectures.

Note: Dell's fiscal year ends in January (FY2026 Q4 = Nov 2025–Jan 2026). SMCI's fiscal year ends in June (FY2026 Q2 = Oct–Dec 2025). Both periods reflect Q4 calendar 2025 activity.
