At the new product launch event held on March 9, 2022, Apple announced the 'M1 Ultra,' the current top-of-the-line chip for the Mac. The M1 Ultra is a chip that combines two M1 Max dies, and boasts an astonishing spec of 20 cores for the CPU, 64 cores for the GPU, 32 cores for the Neural Engine, and 128 GB for the unified memory.
The top chip 'M1 Ultra', which is an ultra fusion of two M1 Max, has appeared, and the memory bandwidth reaches 800GB / s with a maximum of 128GB of unified memory-GIGAZINE
M1 Ultra is a chip that combines two SoCs called M1 Max, which is a combination of CPU, GPU, memory, etc. In addition, M1 Ultra has succeeded in accelerating the bandwidth between two M1 Max to 2.5TB / s by using a technology called 'Ultra Fusion'. Apple has boasted that this has solved the problems of 'increased latency,' 'decreased bandwidth,' and 'significantly increased power consumption' in the approach of combining two chips.
The graph below is a graph comparing the performance (vertical axis) and power efficiency (horizontal axis) of M1 Ultra and high-end disk read GPU released by Apple at the recital. Compared to high-end graphics cards, Apple claims that the M1 Ultra has comparable performance and power efficiency. Therefore, overseas media The Verge
However, when Mac Studio with the M1 Ultra was released on March 18, 2022, benchmark tests revealed that the M1 Ultra wasn't as fast as the RTX 3090, The Verge reports.
The graph below summarizes the results of measuring GPU performance on a Mac Studio equipped with M1 Ultra and a PC equipped with RTX 3090.
In addition, the graph below shows the results of playing ' Shadow of the Tomb Raider ' at various resolutions and experimenting with how much frame rate will be obtained. Mac Studio with M1 Ultra has a frame rate of 108fps when playing in full HD (1080p) image quality, while RTX 3090 has a frame rate of 142fps at the same resolution.
However, The Verge said, 'It's clear that the M1 Ultra and RTX 3090 are competing with each other, and it's also true that in some situations it's far more profitable to use the M1 Ultra. The fact that the graph did not reveal is that the M1 Ultra's upper limit has stopped in the graph, while the RTX 3090 was able to perform better with higher power consumption. ' Although the RTX 3090 is far superior in terms of performance, the M1 Ultra has achieved amazing power efficiency, and Apple's graph is certainly correct in that regard.
Apple also praises UltraFusion technology for its success in 'combining two chips and doubling benchmark test scores,' something other semiconductor makers couldn't do. NVIDIA is trying to combine two GPUs with technology called ' NVLink ' and AMD with ' Infinity Fabric ', but the maximum bandwidth between GPUs is 112GB / s and 800GB / s, respectively, M1 It has not been as fast as Ultra. In fact, NVIDIA has virtually removed support for multi-GPU in the RTX 30 series, and the only model available at the time of writing is the RTX 3090.
Also, since Apple develops everything from the OS to the hardware in-house, M1 Ultra and macOS work seamlessly, while in the case of NVIDIA and AMD, Windows and the game side support NVLink and Infinity Fabric. Due to the need, some titles have been reported to have poor performance when playing on multiple GPUs.
In addition to the above advantages, the M1 Ultra competes with the RTX 3090, citing that the RTX 3090 alone is about the same size as Mac Studio and costs about one-third the cost of the top-level configuration of Mac Studio. The Verge points out that the chip is ready to go.
