For comparison... my 16 GHz LeCroy oscilloscope puts out 40 Gsps * 4 channels * 8 bits of raw ADC samples, not counting the flatness corrections done in gateware/firmware.
That's 160 GB/s or 1.28 Tbps of raw samples.
That would even fit in NVLink 2.0 much less the current gen4/5 stuff.
Imagine four channels of 16 GHz bandwidth waveform data straight into a (very large) GPU nonstop... We'd have to do a hell of a lot of optimization to ngscopeclient to keep up and probably add multi-GPU support but it would be so much fun lol.
