10073D Passive Probe Bandwidth

The followings are spec. of 10073D Passive Probe
Bandwidth: 500 MHz
System risetime (calculated): <700 ps
Attenuation Ratio: 10:1
Input resistance: 2.2 MΩ (when terminated into 1 MOhm)

How can I calculate Probe Bandwidth ?
f3db not equal to 1/RC ?
R means input resistance, 2.2 Mohm,
C means input capacitance, 12 pF.
1/RC is about to 6 kHz that is far from 500 MHz,
What's relation between "bandwidth" and RC corner ?
