Chart on the left shows the bandwidths of memory transfers on Jetson K1 (Click to enlarge). For the baseline we also added GTX680M’s host-device and device-host (peak device-device is ~90K – too large for this chart).
Summary of Jetson K1’s bandwidthTest results, two of which are quite unusual:
- peak device-device is ~7.5x smaller than GTX680M’s
- peak pinned host-device is ~12x smaller than GTX680M’s
- peak pinned device-host is only ~2x smaller than GTX680M’s (!)
- peak pageable host-device is ~1.5x higher than pinned host-device (!)
