Tesla’s New AMD Graphics Chipset Should Have Sony PS5 Performance

tesla’s-new-amd-graphics-chipset-should-have-sony-ps5-performance

During Computex 2021 (aka Taipei International Information Technology Show), AMD disclosed it is providing APU- and RDNA2-based GPUs to Tesla to use in its new Model S and Model X’s infotainment systems. That explains Tesla’s bold claims, noted on its website, that “[u]p to 10 teraflops of processing power enables in-car gaming on-par with today’s newest consoles” in its Model S and Model X vehicles. Essentially, Tesla is putting a gaming computer on wheels, but more importantly, it shows the company is doubling down on a smart-connected vehicle future.

The Hardware

The current MCU2 (the second-generation media control unit) found in all Tesla models on sale today uses an Intel Atom processor, which is a lower-end product usually found in budget laptops. This new chipset from AMD—some Tesla fans have dubbed it “MC3″—should be a major upgrade, and Tesla claims it will be in vehicles this month. The APU (a CPU with an integrated, lower-performance GPU) generally handles the media system, using less power to handle simple tasks. The high-power dedicated GPU kicks in for high demand applications such as AAA games.

According to an earlier leak from developer Patrick Schur on Twitter, this high-power chip is based on AMD’s Navi 23 GPU, which should put it more or less on par with Sony’s PS5 gaming console in terms of raw computing power. Since the new Tesla infotainment screen has a 2200 x 1300 resolution, gaming performance should be at least equivalent to a PS5 hooked up to a 4K (3840 x 2160) TV.

Overall, this new chipset from AMD is a huge leap from the old Intel chip; think of it like going from a $400 netbook to a $2,000 gaming laptop. However, this change to a higher end chipset may put Tesla in a slight manufacturing disadvantage for a while, as the current global microchip shortage and strong demand from both gamers and crypto miners means GPUs are scarce. The demand is far bigger than supply, and manufacturing can’t scale up quickly to accommodate the demand, so don’t expect this new chipset to trickle down to higher volume Teslas such as the Model 3 and Model Y any time soon.

(Speaking of crypto-mining, the AMD GPU should provide 40-60 MH/s—millions of hashes per second—for mining Ethereum, but don’t buy a Model S as a mining rig. At the current rate, profit is roughly $4 a day, you will need 20,000 days to reach ROI, unless you “diamond hands” hold and ETH moons someday. And it’s not like Tesla would let you install any mining software, anyway.)

The Software and Future Potential

Nerdy hardware talk aside, what does this new chipset bring to the in-car experience? A smoother infotainment UI should be the most noticeable benefit. The Intel Atom chip from 2018 has started to show its age as Tesla added more functions throughout the years; the in-car browser can’t even scroll smoothly on this site, motortrend.com. And entertainment features such as Netflix and YouTube UI have started to feel sluggish. The new chip will almost certainly improve the UI experience.

Being able to run AAA games—big-budget blockbuster video games, in other words—is a gimmick that helps sell an expensive car, but it’s a gimmick no other brand has attempted. But there is more to it below the surface: This highly capable hardware paves a path for extra revenue for Tesla in the future, should it decide to sell games and apps on its own platform. The gaming industry is worth $150 billion; Apple’s AppStore made an estimated $64 billion in 2020.

Tesla has the ability to reach a user base of over a million owners, so selling software and subscription features is a potential revenue stream that is difficult to ignore. When driver-assistance technology becomes more mature in the coming years, and drivers don’t have to monitor the road at all times, the in-car infotainment system may become the major feature for car buyers.

It took Apple’s iOS 13 years to build up a customer base capable of generating $64 billion in one year. Since Tesla is intent on developing true self-driving systems in the future, it makes sense to start thinking about how to lock their customer base into their software ecosystem.

Game Time

To see how the current MCU stacks up, we booted up some AAA games for an unscientific test. It worked … with a few caveats.

As mentioned above, due to chip shortage, don’t expect to play AAA games in the Model 3 and Model Y anytime soon. But what if you really wanted to play high-end games while waiting in line for an available Supercharger in a parking lot (stationary, absolutely NOT driving on the road), and you didn’t have the latest Model S or Model X? Well, Tesla’s in-car browser is based on Google’s Chromium—the open-source code that underpins Chrome and many other browsers—and Google has a game streaming service named Stadia, so in theory you can play AAA titles through the in-car browser.

I plugged in my Stadia controller to an in-car USB slot, opened up the browser and logged into my Stadia account. And … it worked. I was able to play Star Wars Jedi: Fallen Order on a Tesla Model 3’s screen.

But it didn’t work well. In fact, it was nigh-unplayable, due to frequent disconnects and numerous input lags. Game streaming requires a stable internet connection, and the car’s network module failed to provide that. Whether it was on full bar LTE cellular or a stable WIFI home internet, the MCU2 struggled to maintain a stable connection. Still, it works, in a technical sense, and the better internet module that will come with the MCU3 hardware improvements should bring Tesla’s dream of premium gameplay to a small screen near you.

Tesla Model S Plaid Fast-Charging and Range Test: How Far Can It Go?

tesla-model-s-plaid-fast-charging-and-range-test:-how-far-can-it-go?

When the now popular Tesla Model S electric car was first introduced in 2012, there were no Superchargers available. Today, there are 25,000 Tesla Superchargers around the world, and with the Model S Plaid adopting a new powertrain, Tesla was able to re-design the battery to take advantage of the third-gen 250-kW Supercharger. Despite Tesla still using the 18650 form-factor cylindrical battery cells, these now have improved chemistry to deliver higher performance and durability. (This is the fourth major chemistry improvement since the first Model S.) With it newest 100-kWh battery pack, Tesla claims the Plaid can recover 187 miles of driving range in 15 minutes of charging at a V3 Supercharger. But just how realistic is that claim in practice? 

First, a little background on charging an EV in general. Many factors are in play to determine the charging performance, from ambient temperature to battery temperature to state of charge to charging station type. As a result, charging rates do vary in practice. Lithium-ion batteries have a certain working temperature range, typically 40-130 degrees Fahrenheit, and the higher end of the range is typically conducive to rapid charging. For an electric car that has sat unplugged overnight or in cold weather, charging time is prolonged. In a Tesla, when a driver puts a Supercharger into the navigation as its destination, the car preconditions the battery pack for rapid charging before it reaches the plug.  This helps to deliver a more consistent rapid-charging experience and eases congestion at charging sites. 

The V3 Supercharger

In our testing, with a preconditioned battery pack and an ambient temperature of 71 degrees, the Tesla Model S Plaid needed 51 minutes to charge from 5 to 95 percent, which added 87 kWh. The latter figure indicates the usable battery capacity is about 97 kWh, with 3 kWh as a buffer. As shown in the charging curve, it indeed reached the 250-kW maximum V3 Supercharger rate and sustained that figure for the five minutes it took to charge from 10 to 30 percent. 

In order to take advantage of peak charging rate, showing up to a Supercharger with the Model S Plaid depleted to between zero and 5 percent of its full charge is the optimal starting point. After the peak, the charging rate gradually ramped down as the pack’s state of charge increased. (Imagine people rushing into an elevator: It’s easy when the elevator is empty, but as more people get in, it takes longer to let them find space to wiggle through.) If you’re on a road trip, 60 percent is a good point to stop charging the car and continue driving until you reach the next Supercharger. The reason is, after 60 percent, the charging rate begins to dip below 2 kWh per minute, so you may as well go to the next charging site, at least from a pure time standpoint. And hey, 18 minutes of charging time is good for another bathroom break. 

As for Tesla’s claim of adding 187 miles of range in 15 minutes of charging time, it is pretty dead-nuts accurate with a Model S Plaid. (At least with the standard 19-inch Tempest wheels.) However, this can only happen when you begin charging the car when it already has a low amount of juice remaining. And on a Model S Plaid with the more energy consumptive optional 21-inch wheels, you are looking at adding 167 miles of range in 15 minutes.

Range: Dragstrip vs. EPA vs. MotorTrend’s Real-World Estimate

Manufacturers love to talk about their electric cars’ range to sell people on buying an EV, but in reality, range is heavily dependent on the way you drive, traffic, and weather conditions. The Model S Plaid with 21-inch wheels uses 2.5 percent of its battery to finish a quarter-mile run on a racing dragstrip, so in theory—we didn’t actually launch it repeatedly until its battery died—it has roughly 10 miles of range if used for 40 consecutive dragstrip runs. Tesla says the Model S Plaid with the 21s has an EPA-estimated 348 miles of range, and that is according to EPA’s conditions and using a mix of 55 percent highway and 45 percent city driving. See the range difference from different use cases there? 

We took the Tesla Model S Plaid on separate road routes for highway (70-75 mph) and city driving, then looked for the efficiency. We drove the car four times on each route, two times with air conditioning on and set to 72 degrees, and two times with it off and only the fan on.

With the ambient temperature below an average of 75 degrees, we saw 3.43 miles/kWh for city driving and 3.14 miles/kWh on the highway. Using the same EPA highway-to-city ratio, our theoretical measured range is 318 miles. 

Multiply the number with energy, and you can reveal the estimated range. For example, on a road trip, chances are you would drive mostly on a freeway or highway, so you’re looking at 305 miles of total range. However, in real life, chances are you are not driving from a fully charged pack to empty. Let’s say you recharged 72 kWh (from 5 to 80 percent): Expect about 226 miles of driving on a freeway at 70-75 mph.

No Yoke, the Refreshed Tesla Model S Ditches the Round Steering Wheel Entirely

  3. No Yoke, the Refreshed Tesla Model S Ditches the Round Steering Wheel Entirely

It’s yoke or nothing for buyers of the updated electric sedan.

Despite it appearing in images pulled from Tesla’s own website, as well as making cameos in a handful of the automaker’s test cars, a traditional round steering wheel is not in the cards for the refreshed Model S electric vehicle. Instead, the brand is committing to the funky yoke-style steering device that the updated luxury sedan debuted with, which looks much like a normal steering wheel sans the upper rim. For those with a knack for pop culture, think of the steering setup used by Knight Rider‘s K.I.T.T.

Admittedly, we rather like the design of Tesla’s new tiller (admit it, it looks cool), however, we were left underwhelmed by its execution after a week of living with a so-equipped Model S Plaid. This was especially true when driving at lower speeds where the car’s quick, but not quick enough, 14.0:1 steering ratio made it difficult to complete near-full-lock turns without awkwardly fumbling for the device’s (purposely) missing upper rim out of habit. 

We’ve heard a variety of reasons for Tesla’s decision to fit every variant of the new Model S (and presumably the similarly updated Model X SUV), ranging from the company’s hope to improve visibility to the car’s gauge cluster to its desire to create a better Autopilot experience, but we have yet to hear any rumblings that the automaker has any plans to offer a traditional steering wheel as an alternative to the yoke. 

Sources within Tesla revealed the steering wheels seen fit to aforementioned 2021.5 Model S prototypes were strictly there for engineering purposes. Nevertheless, it’s clear Tesla has the resources and capability to build and offer a more traditional steering wheel for the updated Model S. While the revised EV is currently offered exclusively with the yoke, it’s possible a more typical steering wheel may find its way to the car’s cabin as an optional feature in the future. After all, Tesla moves quickly and the brand may simply decide to fast-track production of a full-rimmed steering wheel for the refreshed Model S if enough customers find the yoke more charming in theory than in practice.

  3. You Can Buy Ken Block’s Menacing 1977 Ford F-150 Hoonitruck

The 914-hp, Ford-GT-engined Ford pickup premiered in Gymkhana 10.

The widebody F-150 pickup truck premiered in Gymkhana 10, where the tire slayer wreaked havoc through Route 66 in Shamrock, Texas. He topped off his tire-slaying tour by drifting around a drove of artfully staged rusted vintage cars. But the career highlight of this custom Ford F-150 came when it conquered the allegedly most dangerous road in China, the Tianmen Shan Big Gate Road located within Tianmen Mountain National Park.

Peeking through the hood is a 3.5-liter twin-turbo V-6 EcoBoost pulled from the Ford GT Le Mans race car. The modified engine develops 914 horsepower and 702 lb-ft of torque, routed to all four wheels via a Sadev six-speed gearbox. The customization includes a tube frame chassis and military-grade aluminum bodywork, finished in the signature matte black and gray color scheme. It has a carbon fiber dashboard, Recaro race seats, FordPass remote start, and a backup camera.

The raucous Hoonitruck comes fitted with a uniquely designed set of Fuel Block forged beadlock wheels painted in gloss white and rides on ST/KW suspension. Because the widebody flares make the pickup truck just over 79 inches wide, an issue during transportation. Detroit Speed in Mooresville, North Carolina, designed the Hoonitruck to be highly modular. If any problem arises or in case of an accident, the truck can be taken apart and rebuilt on-site.

Detroit Speed built the hardcore F-150 pickup from the ground up, and it reportedly cost upwards of $1.5 million to bring to fruition. LBI Limited is handling the sale, and the asking price is a mind-boggling $1.1 million—a decent discount, we suppose? Additional parts included in the listing are an extra 3.5-liter V-6 EcoBoost engine, wheels, body panels, and suspension components.
