Apple M5 Ultra vs M3 Ultra: What's changed? - Engadget

Here's how the company's most powerful chip ever stacks up with the previous generation. Apple just launched the new M5 Ultra for the latest Mac Studio and as you'd expect, it's the fastest consumer processor the company has ever built. But how much speedier is it than its predecessor, the M3 Ultra? Let's dive in and see how Apple's latest super silicon measures up. If you've followed Apple's Ultra chip family so far, you've probably noticed that it has skipped the M4 and M6 generations and only come out as M1 Ultra, M2 Ultra, M3 Ultra and now M5 Ultra versions. The reason for that (and the delay compared to Apple's other chips) is because of the complexity — they're effectively two processors mated together using Apple's "Ultrafusion" bridge technology. This chip fusion design has carried forward to the M5 Ultra, but there's a key change from before. The M3 Ultra married two M3 Max dies with over 10,000 high speed connections, according to Apple. However, the M5 Ultra fuses two dual-die M5 Max chips to form an all-new quad-die architecture, a first for Apple silicon. The new chip also has six times the connection density and boosts the interconnection speed to 4.4TB/s, up from the
