Three major events spell the fate of the stocks of three major tech companies today. Nvidia, Intel and AMD have all been gearing up and making some changes to their products and lineup of services, all in hopes of overturning company performance and overall market position.

What are the major changes in these companies?

Nvidia just recently revealed its handheld and Android-based gaming system named Shield. The gaming console offers open source software support. This allows users to customize the operating system more conveniently. Though Nvidia warned that the customization option only caters to those who are well aware of how it should be done and used.

"To be sure, this is double-diamond stuff," Nvidia published in a blog post.

"If you're not a coder or already set up with an Android development environment you should skip downloading these tools."

As a hybrid between a gaming laptop and a real console or computer, the Nvidia Shield has been attracting great attention. The Android gaming system offers people a potentially gaming experience but with all the portability. With the constant debate over Xbox One and PlayStation 4, Nvidia is providing the market with a fresh, new option.

This can be a game-changing venture for the company in future.

Intel, on other hand, broke ground for its 450 mm water production. According to a report from ExtremeTech sports, the company's latest foundry will start operating in 2015. The company will be spending around $2 billion to cover bring-up costs for the rest of the year. Since foundry was increasingly becoming costly throughout the years, the new 450-mm facility will most probably set records especially in this category.

Lastly, Advanced Micro Devices or AMD decided to cut the price of its Radeon HD 7990. The company reduced the price to less than $200. This was $100 cheaper compared to its price tag last July. AMD decided to cut prices becaue other competitors were offering similar products at lower prices.
