NVIDIA's RTX Spark bandwidth clarified: 600GB/s is NVLink, not memory speed
A Reddit sleuth exposes a major reporting error on RTX Spark's bandwidth at Computex.
Deep Dive
A Reddit user has pointed out that every outlet reporting 600GB/s from Computex slides is completely wrong—that figure is actually the NVLink interconnect speed.
Key Points
- 600GB/s claimed memory bandwidth for RTX Spark is actually the NVLink interconnect speed for multi-GPU setups.
- Error originated from misinterpretation of Computex slide annotations by tech media outlets.
- Actual memory bandwidth remains unpublished; estimated at 300–400 GB/s based on hardware specs.
Why It Matters
Accurate memory bandwidth specs are critical for AI professionals planning high-throughput training and inference on RTX Spark.
