YouTuber Dave Lee of Dave2D fame has demonstrated how Apple’s new Mac Studio equipped with an M3 Ultra chip can efficiently run a huge version of the DeepSeek R1 AI model locally, provided that users spec the machine with the maximum 512GB of memory.
According to Lee’s testing, the 671 billion parameter AI model can be executed directly on Apple’s high-end workstation, but it requires substantial memory resources, consuming 404GB of storage and requiring the manual allocation of 448GB of virtual RAM through Terminal commands.
The M3 Ultra’s unified memory architecture is key to this performance, allowing the system to handle a 4-bit quantized version of DeepSeek R1 efficiently. The quantization slightly reduces accuracy, but it maintains all parameters and delivers approximately 17-18 tokens per second, which is sufficient for many practical applications.
Perhaps most impressively, the Mac Studio accomplishes this while consuming under 200 watts of power. Comparable performance on traditional PC hardware would require multiple GPUs drawing approximately ten times more electricity.
The capability to run such advanced AI models locally offers privacy advantages for sensitive applications like healthcare data analysis, where sending information to cloud services raises security concerns.
However, this performance doesn’t come cheap – a Mac Studio configured with M3 Ultra and 512GB of RAM starts at around $10,000. Fully maxed out, an M3 Ultra Mac Studio with 16TB of SSD storage and an Apple M3 Ultra chip with 32-core CPU, 80-core GPU, and 32-core Neural Engine costs a cool $14,099. Of course, for organizations requiring local AI processing of sensitive data, the Mac Studio offers a relatively power-efficient solution compared to alternative hardware configurations.
Apple says the M3 Ultra is the fastest Mac chip it has ever released, thanks to its strategy of fusing two M3 Max chips together using the company’s “UltraFusion” technology. This makes the chip’s specs double that of the M3 Max.
