Investors are piling into AMD shares and selling Intel stock after major chip security vulnerabilities were revealed earlier this week and it totally makes sense.

Enterprises will logically diversify their chip security architecture risk for mission critical applications by buying more AMD server chips in the future. The company’s “architecture differences” have proven immune to the more problematic one of the two disclosed vulnerabilities.

British tech website The Register reported Tuesday that some Intel processors have a “fundamental design flaw” and security issue, which spurred the company to confirm the exploit later in the day.

AMD shares are up 10.4 percent in the two days through Thursday following the report, while Intel’s stock declined 5.2 percent in the same time period, wiping out $11.3 billion of shareholder value.

Two vulnerabilities were revealed, one called Meltdown which affects Intel processors and another named Spectre, which could affect chips from Intel, AMD and Arm.

Intel said Wednesday performance degradation after security updates for Meltdown “should not be significant” for the average user. But the company on a call with investors admitted a decrease in performance of up to 30 percent was possible after fixes under some “synthetic workloads.”

Bank of America Merrill Lynch told its clients the big Intel performance hits were “likely for enterprise and server workloads.”

On the flip side, AMD said any performance hits will be “negligible” after Spectre-related security software updates and there is “near zero risk of exploitation.” The company also confirmed it is not impacted at all by Meltdown due to processor “architecture differences.”

Researchers told The New York Times Spectre is “more difficult to exploit.” Apple also said Spectre is “extremely difficult to exploit” Thursday.

Multiple Wall Street analysts predicted AMD will take advantage of the Intel’s security issues.

AMD could use it as “a marketing edge given differing architectures and no vulnerability yet,” Mizuho Securities analyst Vijay Rakesh wrote in a note to clients Wednesday.

Intel’s high profit margin data center business, selling server chips to cloud computing providers and enterprises, is the chipmaker’s crown jewel.

Rakesh noted Intel had 99 percent market share of the data center market, which represents a huge greenfield opportunity for AMD.

Analysts estimate Intel’s data center group will generate $18.5 billion in sales and $7.4 billion in operating profit in 2017, according to FactSet.

“Longer-term customers could be more motivated to find alternatives at AMD and possibly ARM (CAVM benefits) to diversify the architectural risks,” Bank of America Merrill Lynch analyst Vivek Arya wrote Thursday. “AMD appears poised to be the most direct beneficiary.”

AMD gaining significant market share in the server market is not unprecedented. The company hit 25 percent share in 2006. If AMD is able to reach 10 percent or 15 percent market share of the data center business, it could add billions in revenue to the company’s financial results.

Any increase will be big boon for AMD because the Wall Street consensus for the company’s 2017 estimated sales is just $5.25 billion.

One leading tech industry analyst says the chipmaker will do just that.

“The news of Intel’s processor security issue and the potential performance degradation to correct it comes at an inopportune time as Intel currently faces heavy competitive pressure from its long-time nemesis, AMD,” Fred Hickey, editor of High Tech Strategist, wrote in an email Thursday. “AMD’s new line of chips is a significant challenger for the first time in many years (since AMD’s Opteron chip days).”

AMD launched a new line EPYC datacenter processors to much fanfare last June with design wins at cloud computing providers Microsoft Azure and Baidu.

“For Intel, it likely means loss of market share (lower revenues) as well as loss of pricing power (lower gross margins) as the advantage shifts to the buyers and away from Intel, which has totally dominated the PC/computer server processor market in recent years,” Hickey added. “AMD’s new processor chips already had momentum and that momentum will likely be propelled further by the recent security issue disclosures.”
