The M1 Ultra is Apple's latest and greatest in-house chipset — and it's so good that Apple claims it's more powerful than the Nvidia RTX 3090. While Apple's most often associated with iPhones and Macs, the company also makes some of the most advanced computing chips. Whether it be the A15 Bionic in the iPhone 13 or the M1 inside the iPad Air 5, Apple's chips are among the best in the business.
This has been true of Apple's smartphone chips for quite a few years, but only since M1 was released in 2020 has it also applied to Apple computers. Following the introduction of M1 Macs in November 2020, Apple's since succeeded the normal M1 with M1 Pro, M1 Max, and M1 Ultra — with each one offering more horsepower than the last. M1 Ultra is by far the fastest Mac chipset Apple has released to date, and on the graphics side of things, Apple claims the M1 Ultra GPU is better than the flagship RTX 3090 from Nvidia. That's a bold claim on paper, but does it actually hold any weight?

The M1 Ultra's GPU specs are nothing short of impressive. The baseline version has 48 GPU cores and can go up to 64 GPU cores with its maxed-out variant. It also touts 2.5TB/s of total memory bandwidth. By comparison, the RTX 3090 has less than half the memory bandwidth at just 936.2GB/s. In one of its marketing slides for the M1 Ultra, Apple claims that its chip has faster overall GPU performance than the RTX 3090 — all while using about 200W of less power. Looking exclusively at those numbers, it's easy to think that the M1 Ultra's GPU is far superior to the RTX 3090. Right?
As is often the case with these things, there's more to the story than Apple's own marketing claims.
