Anthropic reportedly testing Advanced Micro Devices ( AMD) GPUs, as the AI giant is reducing its reliance on a single computing power source. SemiAnalysis, when analyzing GitHub code publicly posted by an AMD AI executive, discovered that Anthropic will be listed as an AMD customer with a maximum priority score of 30. AMD has provided MI350X accelerators to Anthropic for evaluation. Anthropic has previously partnered with multiple chip suppliers, including Google TPU and Samsung. If AMD can successfully enter the high-end AI training market, which was previously dominated by Nvidia, it would be a landmark milestone for the company.

The chip sector is enjoying a breather after last week's brutal sell-off, but this week is the real 'ultimate test.' Earnings from Google and Tesla will directly test whether AI demand continues to exceed expectations and whether massive capital expenditures can deliver returns.
