Apple M3 Ultra
Overview
Two M3 Max dies joined by Apple's UltraFusion packaging over more than 10,000 connections, giving a 32-core CPU, up to 80 GPU cores and a 32-core Neural Engine. Configurable to 512 GB of unified memory, more than any other personal computer, which is why it is the desk-side machine of choice for running large models locally. Apple publishes no FLOPS figure; the values here are theoretical peak, derived as twice the M3 Max in line with the two-die design. Note that Apple's "up to 2x faster than M2 Ultra" claim describes workload performance on an architecture that added hardware ray tracing, not raw FP32 throughput, where the gain over M2 Ultra is nearer 1.2x.
