Tesla Lowers Estimates for Model 3 Lineup in Europe Due to AMD Ryzen CPU’s Extra Power Consumption

Tesla made several changes to the Model 3 and Model Y configurations in Europe last night.

The Model Y got an increase in range, with the long-range variant increasing to 28 km (17 miles).

Conversely, the Model 3 Long Range has seen its estimated range decrease. The change was not substantial, only decreasing by 11 or 12 km (~7 miles) depending on the wheels selected.

There was apparently no explanation for the change, as the source code did not note a different battery which could lead to a lower range estimate.

Turns out there was an explanation, and it’s due to the new AMD Ryzen processors.

According to an internal email sent to European service centers this morning, details of which were shared with Driving Tesla, the new processors require more power than previous Intel Atom processors, resulting in a slightly lower range estimate.

The processor is no slouch with up to 10 teraflops of processing power, enough to rival high-end home gaming systems like the PS5.

Additionally, the Rear-Wheel Drive (RWD) and Performance Model 3 models did not have their ranges adjusted as they had already been taken into account when the estimated ranges were updated late last year.

Interestingly, when Ryzen CPUs were launched in China, there was no corresponding lineup adjustment in that market. We haven’t seen similar lineup adjustments in North America either.

This could be due to different testing standards (EPA vs WLTP vs CLTC).

Tesla first added AMD Ryzen processors with the launch of the Model Y Performance in China in December. The modification was made simultaneously to the Model 3 and the Model Y and appeared only a day later.

It took a few more weeks to arrive in North America, with Fremont-made cars gaining the feature in late December.
