AMD's Ryzen CPU Reportedly Cuts Down Tesla Model 3's Driving Range

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

Tesla Model 3 Range Decreased By two.4% On Average Later Installing AMD Ryzen Processors Suggests Data

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

Tesla's message reads as follows:

Nosotros have updated Model 3 vehicles to optimise the impact screen feel with our new car calculator. This hardware modify requires more power, resulting in a small-scale drop in range. Your Model 3 range is now 602 kilometers (WLTP), 22 kilometers less than originally communicated.

Information technology then proceeds to ask the user whether they would nevertheless like to proceed with the pre-society. As Teslascope notes in its tweet, the message has not been sent to all customers who accept pre-ordered a Model three for themselves or others, and the one sent in Commonwealth of australia is due to stricter consumer protection laws in the land.

The Ryzen has been present inside Tesla'due south other electric vehicles, such as the Model South Plaid and the Models S and X since last year, and a teardown of the Model S Plaid'south Media Command Unit revealed the specifications of the processor.

According to YouTuber Ingineerix, the Model Southward Plaid's MCU Ryzen had the following specifications:

The main processor is now an AMD Ryzen YE180FC3T4MFG (4 cadre 45 watt Ryzen Embedded) 512 KB L2 cache per core, 4 MB L3 cache.

The GPU is also an AMD Radeon marked 215-130000026, closest guess is a similar to a Radeon Pro W6600.

Wifi/BT Module is an LG Innotek ATC5CPC001

Cell Modem is a Quectel AG525R-GL

Gateway is still the venerable SPC5748GSMMJ6

DSP 1 is an ADSP-SC587W SHARC+ Dual Cadre DSP with ARM Cortex-A5

DSP 2 is an AD21584 SHARC+ Dual Core DSP with ARM Cortex-A5

Ethernet Switch is a Realtek RTL9068ABD

Insideevs, which originally picked up the report from Teslascope shares more details for the Model 3 range reduction. It reports that:

Model 3 RWD (no changes)
18" wheels: 510 km (317 miles)
19" wheels: 491 km (305 miles)
Model 3 LR AWD
eighteen" wheels: 626 km (389 miles), down by 11 km or 1.7% from 637 km
19" wheels: 602 km (374 miles), downward past 12 km or 2.0% from 614 km
Model 3 Performance
20" wheels: 547 km (340 miles), down by xx km or three.five% from 567 km
Model Y LR AWD
19" wheels: 565 km (351 miles), upwards by 28 km or 5.2% from 537 km
20" wheels: 533 km (331 miles), up by 26 km or v.1% from 507 km
Model Y Operation
21" wheels: 514 km (319 miles), upwardly past 34 km or 7.1% from 480 km

The range details were originally shared past the Twitter account Tesla_Adri, who goes further and quotes a source within Tesla confirming that the range reduction is due to AMD'due south chip.

Teslascope had been the first to discover in December terminal year that the 2022 variants of the Models iii and Y were also equipped with AMD's processors.
