Remember when Elon Musk claimed you could play The Witcher 3 and Cyberpunk 2077 on a 10 teraflop gaming rig he crams into the new Tesla Model S and X? AMD officially offers the guts – during its Computex 2021 keynote, the chipmaker just revealed that the new Tesla infotainment system consists of an AMD Ryzen processor combined with an AMD RDNA 2 GPU.
“So we actually have an AMD Ryzen APU that powers the infotainment system in both cars, as well as a discrete RDNA2-based GPU that kicks in when running AAA games and delivers up to 10 teraflops of computing power…. to give gamers a great platform for AAA gaming,” said AMD CEO Lisa Su.
And if you combine that information with some other news AMD revealed today, plus an earlier leak in January, we may now have a vague idea of just how powerful that “10 teraflop” infotainment system could theoretically be: probably slightly less than Sony’s PS5. .
You see, leaker Patrick Schur dug up a Tesla block diagram in January who picked out an AMD Navi 23 GPU especially for Tesla’s new vehicles, and today AMD announced the new Radeon 6800M, 6700M and 6600M laptop graphics chips – the weakest of which happens to use Navi 23, AnandTech reports.
As we learned today, the Radeon 6600M chip comes with 28CUs and 1792 shader units – compared to the 36CUs and an estimated 2304 shader units worth RDNA 2 GPU in Sony’s PlayStation 5, which also claims a 10-teraflop gaming installation. While it’s not exactly apples-to-apples, it’s largely the same tech underneath, and a smaller number of cores on the same GPU architecture suggests we should expect slightly less performance from a Tesla compared to Sony’s console. (The more expensive Radeon 6700M / Navi 22 has the same number of CUs as the PS5, for what it’s worth.)
However, performance depends on the software platform, as we’ve seen with the 10-teraflop PS5 and the 12-teraflop Xbox Series X — and a recent job posting from Tesla suggests game developers may actually be building for Linux if they want to target the new ones. Tesla in car gaming rigs.
However, Linux is not necessarily an advantage when it comes to gaming performance. Google’s Stadia cloud gaming also had 10 teraflops of performance from its AMD GPUs, but ports of games from Bungie and Square Enix didn’t look nearly as good as they did on weaker Xbox and PC hardware at the service’s launch.
The most important question is probably still the one I asked in January: Who’s going to sit in their $80,000 sports car and play a triple-A video game?
Tesla CEO Elon Musk tweeted on Saturday that the Model S Plaid, including the new AMD system, will ship on June 10.
