"Jim Keller Questions NVIDIA's $10 Billion R&D Spending, Suggests Achievability at $1 Billion"

Tenstorrent's CEO Jim Keller criticizes NVIDIA's $10 billion R&D costs on Blackwell GPUs, suggesting that the company could have saved billions by using a more cost-effective interconnect method, such as Ethernet. Keller's criticism stems from the proprietary nature and high cost of NVIDIA's NVLINK interconnect technology. While Ethernet interconnect presents a more affordable and open-source alternative, it is still in the development phase. Despite the debate over R&D costs, the demand for NVIDIA's Blackwell AI GPUs remains high, solidifying the company's dominance in the market.

"Jim Keller's Proposal: Using Ethernet to Connect Blackwell GPUs Could Have Saved Nvidia Billions"

Jim Keller suggests that Nvidia should have used Ethernet instead of proprietary NVLink for chip-to-chip connectivity in its Blackwell-based GB200 GPUs for AI and HPC, as it would have saved money and made software migration easier. Nvidia's use of proprietary interconnect technologies poses a challenge for porting software to different hardware platforms, benefiting Nvidia but not its competitors. While Ethernet is a competitor to Nvidia's InfiniBand, the industry is developing Ultra Ethernet, which may become a viable competitor for AI and HPC workloads. However, Nvidia's current designs continue to leverage proprietary interconnects, and any shift to open-standard technologies may be years away.

"Jim Keller Challenges Sam Altman's Trillion-Dollar AI Chip Ambitions"

Renowned chip designer Jim Keller criticizes OpenAI CEO Sam Altman's plan to seek $8 trillion in funding for AI semiconductor ambitions, stating that he could achieve the same goals for less than a trillion dollars by focusing on architectural enhancements and supply chain improvements. Keller's company, Tenstorrent, is working on AI-based chip architectures and recently partnered with Samsung Foundry to develop next-gen RISC-V-based chiplet designs. Industry experts, including NVIDIA's CEO Jensen Huang, question the feasibility of Altman's ambitious plans and emphasize the importance of architectural changes in addition to production volume increases in the semiconductor industry.

Jim Keller's Projections for AMD's Zen 5 CPUs: Huge Performance Gains Expected.

Jim Keller, former AMD chip architect and current acting CEO of Tenstorrent, revealed performance, frequency, and power estimates for AMD's next-gen Zen 5 CPU architecture, expected to launch in 2024. Tenstorrent estimates a 30% performance gain over Zen 4, with the Zen 5 expected to be the first server CPU to hit 4 GHz. The architecture will feature enhanced performance and efficiency, a re-pipelined front-end, and integrated AI and machine learning optimization.
