Chip designer Advanced Micro Devices, Inc (AMD) Ryzen microprocessors installed inside U.S. electric vehicle manufacturer Tesla, Inc's Model 3 electric vehicles are reducing their driving range according to a report from advisory service Teslascope. Tesla, which had previously used Intel Corporation's Atom processors for its infotainment systems, has recently made the switch to AMD devices, and the report shows that Tesla customers who had pre-ordered a Model 3 are now being asked by the company to accept a range decrease for heir vehicle in some jurisdictions due to consumer protection laws. Additionally, the range for Tesla's Model Y also appears to have increased, but this seems to be due to the vehicle receiving larger batteries.

The report from Teslascope came in the form of a tweet that also highlighted how buyers in Australia are required to consent to have their vehicle range decreased since the time a pre-order was made. While the message sent out by Tesla does not explicitly mention AMD, it does state that a new computer for the Model 3 is affecting the vehicle's range.
