Which machine learning share should you buy right now? Let's review the core business models and growth

Machine learning is ushering in an era once imagined only in novels. Machine learning is the reason behind the wondrous technologies like almost flawless Google search results, self-driving cars, AI, robotics, and technology-based healthcare systems.  Let's take a look at the best machine learning stock to buy between AMB and Qualcomm.

Advanced Micro Devices, Inc. operates as a semiconductor company worldwide. The company operates in two segments, Computing and Graphics; and Enterprise, Embedded, and Semi-Custom. Its products include x86 microprocessors as an accelerated processing unit, chipsets, discrete and integrated graphics processing units (GPUs), data center and professional GPUs, and development services; and server and embedded processors, and semi-custom System-on-Chip (SoC) products, development services, and technology for game consoles. Its current machine learning stock is US$95.07, a 1.68% increase from the previous close.

QUALCOMM Incorporated is a technology company working to develop and commercialize foundational technologies and products for mobile devices and wireless products. The company's QSI segment deals with artificial intelligence, among other technology sectors, and it ranks 9th on our list of the best machine learning stocks to invest in. Its current machine learning stock is US$132.12, a 0.40% increase from the previous close.

Both AMD and Qualcomm saw their stock prices surge to all-time highs last year, but both companies' plays have stumbled in recent months as rising interest rates drove investors out of tech stocks and into more conservative investments.

AMD and Qualcomm both spent a lot of their free cash flow on big buybacks in recent years. However, AMD's share count actually increased 66% over the past five years (partly due to its all-stock takeover of Xilinx) while Qualcomm's number of outstanding shares declined 24%.
