Intel earnings story updated with comments from CEO Paul Otellini, who spoke on the company's earnings conference call.

NEW YORK ( TheStreet) -- Bolstered by a tech spending environment that's becoming more corporate vs. consumer-based, Intel ( INTC - Get Report) posted record quarterly revenue and profit Tuesday after the bell.

Intel posted adjusted earnings of 59 cents a share and quarterly revenue of $12.9 billion, versus analysts' expectations of 46 cents EPS and sales of $11.6 billion. Those numbers are up from the year-ago period, when Intel reported 43 cents profit on revenue of $10.3 billion.

"Those revenue numbers are spectacular," Doug Freedman, an analyst from Gleacher & Company, said on CNBC. " Intel has more things moving on the revenue line than we've ever really seen before."

Investors responded positively to the numbers, initially pushing Intel's stock up $1.20, or 6.04%, to $21.06 in extended trading.

Intel attributed its strong performance largely to robust enterprise demand, with the company's data center revenue climbing 32% compared to the prior year. The chipmaker's PC Client Group also registered a 17% year-over-year increase in sales.

"The first-quarter revenue was an all-time record for Intel fueled by double digit annual revenue growth in every major product segment and across all geographies," said Paul Otellini, Intel's president and CEO. "These outstanding results, combined with our guidance for the second quarter, position us to achieve greater than 20% annual revenue growth."

The chip giant offered up healthy guidance, predicting revenue between $12.5 billion and $13.3 billion. Analysts surveyed by Thomson Reuters had forecast revenue of $11.87 billion. The company also expects to maintain its gross margin at 61%, similar to its first quarter.

Later, on the company's conference call, Otellini said that while some of Intel's sales and marketing offices in Japan sustained damage during the recent earthquake and tsunami, it wasn't great enough to impact service to customers. "As for our business, we did not see any unusual change or fluctuations to our backlog after the earthquake," he said. "And there's no major impact to our supply lines moving forward -- our PC supply chain levels remain healthy as we enter the second quarter."

Despite the stellar results, investors will likely want to see more hardcore evidence of Intel moving further into the mobile device market, a sector where the chip giant has lagged behind competitors like Arm Holdings ( ARMH).

Speaking to this, Otellini said that he would be surprised if "12 months from now, you don't see Intel-based smartphones" on the market. He also said that Intel is "actively working with a large number of of handset makers and carriers on Medfield-based designs" and is "committed to success in the smartphone segment." Intel, he said, is working on chip designs for platforms including Nokia's ( NOK) Meego, Google's ( GOOG) Android and Microsoft's ( MSFT) Windows.

Over the course of the year, Intel chips should also power upcoming tablets, including ones running on Google's tablet-designed Honeycomb operating system.
