On Tuesday, Intel (Nasdaq: INTC) reported EPS of $0.59, up 37% year-over-year. Revenue of $12.9 billion grew 25% and came in well above the consensus estimate of $11.6 billion. Management forecasts second-quarter revenue of $12.3 billion to $13.3 billion, again smashing consensus estimates of $11.9 billion.

A 14-week quarter (instead of the usual 13), strong corporate demand, and emerging markets contributed to the strength despite several challenges. Headwinds included problems with its new Sandy Bridge processor, weak PC demand in mature markets, and the devastation in Japan.

The news seemed to erase a lot of concerns. Intel approached gains of nearly 8% in late trading and several analysts raised their price target on the stock.

Much of the discussion on the earnings call centered on datacenter demand and emerging markets. For the quarter, datacenter group revenue grew 32% while PC client group revenue grew only 17%.

Emerging markets represent more than 50% of Intel's business. Management said much of the business in these markets goes to "white box" (no-name) PC makers and therefore is not accurately counted by researchers such as Gartner and IDC. Management acknowledged demand in the U.S. and Europe is weakening thanks to both economic worries and a shift to tablets.

There's a strong case to be made that the demand shift to emerging markets will pressure Intel less than other Wintel members. Lenovo and white box PC makers present a direct challenge for established PC makers like Dell (Nasdaq: DELL) and Hewlett-Packard (NYSE: HPQ). China-based Lenovo bought IBM's PC business in 2005.

But white box makers need basic components. That suggests component suppliers such as Intel, AMD (NYSE: AMD), Seagate (Nasdaq: STX), and Western Digital (NYSE: WDC) can garner a greater share of emerging market demand than PC makers such as Dell and HP. And Microsoft may have less to lose than hardware makers, as software piracy has long dampened its business in emerging markets.

The shift to tablets is a lingering concern. Revenue for Intel's Atom microprocessor and chipset for mobile devices was a mere $370 million and grew only 4% year-over-year. Management sounded optimistic about potential design wins before year's end, but investors are likely to remain skeptical.

Foolish takeaway
Near-term trends seem to favor Intel, but the shift to tablets is a long-term concern that shouldn't be ignored.
