Apple, which is perhaps most famous for creating the popular iPhone handsets, is the world's most valuable brand, with an estimated price of $87 billion (£56 billion).
However, Samsung was hot on its heels after launching successful mobiles like the Galaxy S3 and Galaxy Note 2 alongside other gadgets across 2012.
David Haigh, chief executive of Brand Finance, which compiles the Global 500 list, indicated that these manufacturers are popular and well known among consumers.
"With revenues in the tens of billions, Apple and Samsung are slugging it out for global brand supremacy and are vying with each other to create strong 'customer love' for their brands," he said.
The US firm is renowned for its devoted and loyal customers, who queue outside retail stores for hours to be among the first to get their hands on a new iPhone.
However, the South Korean manufacturer seems to be imposing on the company's customer base by offering unique and innovative products with impressive specifications and attractive designs.
