These results are intended to be relative to each other and easy to interpret even if they have shortcomings. Raw data files are linked above for the curious
| Vendor | Device | T50 (sec) | T100 (sec) | N | S/Ns | Notes |
|---|---|---|---|---|---|---|
| AMD | AM2764ADC | 200.2 | 315 | 5 | EE05
EE06 EE07 EE08 EE09 |

Where:
- N: number of data collections
- T50: estimated typical time half of bits are erased
- T100: estimated typical time all bits are first erased in a stable manner
- estimated typical time: currently RMS of N samples
Baseline is:
- New USHIO G4T5 bulb
- Bulb to chip distance: based on PE-140T EPROM eraser
- Some results are scaled based on calibration tests
- Ex: bulb2 takes longer so results are scaled back
