For the most part, these two don’t compete against each other, and Alphabet is primarily a client of Nvidia’s. However, Alphabet has also built a graphics processing unit (GPU) alternative that competes with Nvidia’s product, although it’s serving a specific niche.
Of these two, which one is the better AI stock to buy now?
Will AI create the world’s first trillionaire? Our team just released a report on the one little-known company, called an “Indispensable Monopoly” providing the critical technology Nvidia and Intel both need. Continue »
Nvidia makes graphics processing units (GPUs), which have long been the go-to choice for computing problems that require massive horsepower. GPUs can process multiple calculations in parallel, making them a great option for arduous workloads like AI. GPUs are also great for other computing tasks, like cryptocurrency mining, drug discovery, engineering simulations, and their original use case, gaming graphics. However, when a GPU is only utilized for one specific workload for its entire life, the extra capacities that clients have to pay for are somewhat wasted.
That’s where a specialized unit like the Tensor Processing Unit (TPU) from Alphabet comes in.
Alphabet has spent the past decade developing the TPU in collaboration with Broadcom (NASDAQ:…
