Apple's M2 Ultra chip chases the Hollywood elite

Most people surf the web, play games, and write emails on their laptops and desktops. That's certainly not the market being addressed by the second-generation Mac Studio, a $1,999 desktop that's zeroing in on professional video editors. The Studio ships with either the option of an existing M2 Max chip, or the new M2 Ultra.

Essentially, the M2 Ultra is two M2 Max chips stitched together, with a total of 24 CPU cores and 76 GPU cores. (The M1 Ultra combined two M1 Max dies for 20 CPU cores and a 64-core GPU, spread across more than 100 billion transistors.) All told, Apple claims that the new M2 Ultra chip will deliver 20 percent faster CPU performance than the M1 Ultra, and 30 percent faster GPU performance than the M1 Ultra, as well. With the launch of the Apple Mac Studio and the M2 Ultra, all of Apple's hardware has now switched over to Apple's own silicon, executives said.

Who needs this? Well, in an ideal environment, the chip could be used to train large machine-learning models, using its massive 192GB of addressable memory — 50 percent more than the M1 Ultra. Most environments use GPUs and their high-speed video memory to perform these tasks, but they'd run out of available memory, according to Jennifer Munn, Apple's director of engineering and program management.

Mac Studios, however, will see some real results: DaVinci Resolve users should see video processing times drop by half, and 3D Octane users will be able to render their models three times faster, Apple said. It's also six times faster than an Int
