AMD Slides 3% Ahead of Earnings as PC Worries Linger; Intel Drops 5%, NVIDIA Edges Higher
Intel's PC warning sent AMD stock tumbling 11% in a single session, but the real question is whether that warning stops at the PC market or follows AMD straight into its AI data center ambitions ahead of earnings.
Advanced Micro Devices (NASDAQ:AMD | AMD Price Prediction) goes into its Q3 2026 earnings report with the chip group divided over how far a PC warning from Intel (NASDAQ:INTC) could spread. AMD stock is at $489.03 in afternoon trading, down 3%. The company is scheduled to report results on November 3 after the market closes. That report could show whether the warning reaches its larger businesses.
The fall adds to a steep drop on October 30. AMD stock fell 11% that day, after Intel said its PC slowdown would last at least through the first half of 2027. Shares of Intel plunged 29% in the same session. Intel stock is down 5%, so that selloff is still running.
How Intel’s PC Warning Dragged AMD Stock Lower
Intel set its Q4 2026 revenue guidance at $15 billion to $16 billion on October 29, below the roughly $17 billion GuruFocus consensus. Guidance for Intel’s adjusted gross margin came in at 38%, down from 44.1% in Q3.
On the earnings call, Intel CEO Lip-Bu Tan said, “In recent weeks, our customers began signaling a PC slowdown based on the memory prices and availability.” CFO David Zinsner added, “Make no mistake, we are not optimistic about next year in terms of memory.”
Demand for Intel’s data center chips held up. The company’s Data Center and AI revenue rose 78% from a year earlier to $7.32 billion. Substrate and memory shortages are still limiting some of Intel’s server supply.
For AMD, Intel’s warning lands on the smaller part of the business. AMD’s Client segment brought in $3.06 billion in Q2 2026. Data Center revenue rose 107% to $6.72 billion, making up 58% of sales. CEO Lisa Su highlighted the PC risk on August 4, saying the company is “planning for a softer PC market as higher memory and component costs weigh on demand.”
NVIDIA Climbs While AMD Slips
NVIDIA (NASDAQ:NVDA) stock is at $206.76, up 1%. The AI leader’s Data Center revenue reached $89.02 billion in Q2 FY2027, up 117%, and NVIDIA has little exposure to the PC cycle.
Gains at NVIDIA suggest traders may see Intel’s problem as a PC issue that leaves AI demand intact. Intel’s own data center strength supports that view, even though its outlook points to a sequential fall. AMD sits between the two camps. It has enough PC exposure to feel Intel’s warning and enough AI exposure to keep the debate open.
How AMD’s Business Model Differs From Intel and NVIDIA
Chip design is the center of AMD’s model, with manufacturing handled by third-party foundries. Its sales come from server processors, Instinct AI accelerators, Ryzen PC chips, gaming and embedded products. Intel works differently: it makes most of its own chips and sells foundry capacity to outside customers. That ties more of Intel’s results to PC demand and factory costs.
NVIDIA’s model is built around AI data center platforms that feel little pressure from PC cycles. Qualcomm (NASDAQ:QCOM), on the other hand, leans on smartphone chips while it builds out automotive, connected-device and data center lines.
What AMD’s Q3 Report Needs to Show
The next test for AMD is whether its Q4 2026 outlook matches the roughly $16.2 billion implied by analysts’ full-year forecasts. AMD guided Q3 revenue to about $13 billion, plus or minus $300 million, against the consensus of $13.09 billion. Any hedging from Su on when customers will bring new data center capacity online could weigh on 2027 estimates that have already moved higher.
Bloomberg analyst estimates have AMD net income growing 501% over four years, with most of that increase expected in 2027 as Helios AI racks ship to customers including OpenAI and Anthropic (we reverse-engineered what the biggest tech winners looked like early in a free playbook). Consensus EPS estimates of $7.62 for 2026 and $15.93 for 2027 reflect that growth. Bears point to AMD’s forward earnings multiple of 45x, above its five-year average of 35x.
Even after the recent pullback, expectations for AMD remain high going into the report. It may make sense to stay cautious until the debate over AMD’s Q4 outlook resolves.
