Radeon RX 7700/7800XT im Test: Oberklasse-Performance wird wieder bezahlbar

Die High-End-Grafikkarten der letzten Generation werden eingeholt. Glücklicherweise ist das beim Kaufpreis anders. Ganz umsonst ist die Performance trotzdem nicht. Ein Test von Martin Böckmann (Grafikkarten, AMD)

Smarter Lautsprecher für unterwegs: Move 2 von Sonos liefert lange Akkulaufzeit

Der neue Sonos Move 2 soll besser klingen, leichter sein und eine längere Akkulaufzeit als das Vorgängermodell liefern. Dazu gibt es eine verbesserte Steuerung. (Sonos, Sound-Hardware)

Review: AMD’s Radeon RX 7700 XT and 7800 XT are almost great

It’s hard to get excited about yesterday’s performance at yesterday’s prices.

Nearly a year ago, Nvidia kicked off this GPU generation with its GeForce RTX 4090. The 4090 offers unparalleled performance but at an unparalleled price of $1,600 (prices have not fallen). It's not for everybody, but it's a nice halo card that shows what the Ada Lovelace architecture is capable of. Fine, I guess.

The RTX 4080 soon followed, along with AMD's Radeon RX 7900 XTX and XT. These cards also generally offered better performance than anything you could get from a previous-generation GPU, but at still-too-high-for-most-people prices that ranged from between $900 and $1,200 (though all of those prices have fallen by a bit). Fine, I guess.

By the time we got the 4070 Ti launch in May, we were getting down to the level of performance that had been available from previous-generation cards. These GPUs offered a decent generational jump over their predecessors (the 4070 Ti performs kind of like a 3090, and the 4070 performs kind of like a 3080). But those cards also got big price bumps that took them closer to the pricing levels of the last-gen cards they performed like. Fine, I guess.

Polestar 2 gets new motor and battery for MY24 refresh, and it’s a winner

It’s faster, more efficient, and a lot more fun to drive.

DENVER—A car's midlife refresh is, more often than not, a mostly cosmetic affair—new light clusters or a changed front fascia, perhaps a new interior. Truth be told, the styling tweaks to the model year 2024 Polestar 2 are subtle—you might notice new wheel designs, and the ersatz front grille has been replaced with a body-colored panel. Instead, Polestar concentrated on tweaking the bits you can't see, making the car more efficient and, in the case of the cheaper, single-motor version, a lot more fun to drive, too.

When Polestar first launched the Polestar 2 in 2020, it did so with a dual-motor all-wheel drive version, followed by a more affordable single-motor model. Although the more expensive, more powerful version was faster, as is often the case with electric vehicles, I found the supposedly lesser car the one to go for. It's this version that has had the most attention paid to it in the refresh, most notably the fact that its single motor now powers the rear wheels, not the front.

Polestar has developed a new electric motor that's significantly more powerful than the one it replaces, outputting 299 hp (220 kW) and 361 lb-ft (490 Nm). That's a 29 percent boost in power and 48 percent more torque than the previous single-motor model.
