19,500times the on-chip SRAM
The memory a Whisper large model needs, about 10 GB, is roughly 19,500 times the 512 KB of internal SRAM on an ESP32-S3.

- What it measures
- This compares the memory a Whisper large model is reported to need with the on-chip SRAM of an ESP32-S3 processor. Both figures are approximate and measure different things: the Whisper figure is for running the model, and the SRAM is the chip's own working memory.
- How it is calculated
- 10 GB = 10,000,000 KB (1 GB = 1,000,000 KB); 10,000,000 / 512 = 19,531, rounded down to 19,500
