M1 Ultra CPU is 60% faster than the 28-core Mac Pro and GPU is 80% faster than the highest-end Radeon Pro W6900X graphics card

The newly announced M1 Ultra is now Apple’s fastest Apple silicon, replacing the M1 Max as the top choice. With the power of the updated chip, the new Mac Studio is capable of outperforming not only the high-end previous-generation 27-inch iMac, but also the top-of-the-line 28-core Mac Pro.

‌M1‌ Ultra chip offers 20-core CPU with 16 high-performance cores and 4 high-efficiency cores, 64-core GPU, 128GB unified memory, 2x more powerful media engine and 800GB/s memory bandwidth.

In terms of CPU performance, the ‌M1‌ Ultra is 3.8x faster than the highest-end Intel Core i9‌iMac‌ (now discontinued) and 60% faster than the 28-core ‌Mac Pro‌ with an Intel Xeon W processor.

On the GPU side, the ‌M1‌ Ultra is 4.5 times faster than the 27-inch ‌iMac‌ and 80% faster than the highest-end ‌Mac Pro‌ with AMD Radeon Pro W6900X graphics. At today's event, Apple touted ‌Mac Studio‌ as "80% faster" than the fastest ‌Mac Pro‌.

‌M1‌ Ultra supports 18 streams of 8K ProRes 422 video, which Apple says no other computer in the world can do.

All of Apple’s silicon chips offer incredible power efficiency, and the ‌M1‌ Ultra is no exception. According to Apple, the ‌M1‌ Ultra is capable of delivering 90% more performance than the fastest 16-core PC CPUs within the same power range, and it delivers the peak performance of PC chips at 100W less power.

It delivers similar performance to "one of the most popular discrete GPUs" while using 1/3 the power, and it delivers faster performance than the highest-end discrete GPUs, but uses 200W less power.

The above is the detailed content of M1 Ultra CPU is 60% faster than the 28-core Mac Pro and GPU is 80% faster than the highest-end Radeon Pro W6900X graphics card. For more information, please follow other related articles on the PHP Chinese website!
