Nvidia has once again made a monumental stride in the realm of artificial intelligence and computing with the launch of its new Blackwell B200 GPU and the accompanying GB200 “superchip.”
Building on the success of the H100 AI chip, which propelled Nvidia to a multitrillion-dollar valuation surpassing giants like Alphabet and Amazon, the latest offerings from the tech behemoth are set to redefine the benchmarks for power and efficiency in AI computations.
During the recent GPU Technology Conference, Nvidia’s CEO, Jensen Huang, showcased the Blackwell B200 alongside its predecessor, underscoring the technological leap embodied in the new hardware.
With a staggering 20 petaflops of FP4 horsepower powered by 208 billion transistors, the B200 GPU alone marks a significant advancement.
Yet, when integrated into the GB200—as a dual GPU setup with a single Grace CPU—the capabilities expand exponentially, offering up to 30 times the performance for LLM inference workloads while slashing costs and energy consumption by as much as 25 times in comparison to the H100.
Notably, training models of unprecedented complexity is now within reach, with Nvidia stating that a task requiring 8,000 Hopper GPUs and 15 megawatts of power can be accomplished with just 2,000 Blackwell GPUs consuming a mere four megawatts.
The introduction of these groundbreaking technologies reflects Nvidia’s commitment to driving innovation in AI computing, setting new industry standards and fueling the ambitions of companies and developers eager to harness the next level of AI capabilities.
