| Spec | Bosch HIS8857UC | Bosch HIS8057U | Weight |
|---|---|---|---|
| Official cooking zonesThe official number of cooking zones on the ENERGY STAR certified record. A missing value is shown as Not listed and scores at the category minimum. | 7 zones | 5 zones | 25% |
| Official maximum cooking-zone wattageThe highest official cooking-zone wattage published on the ENERGY STAR record. This is a certified nameplate figure, not a measured boil-time test. A missing value scores at the category minimum. | 3700 W | 3700 W | 30% |
| Computed total cooking-zone wattageThe sum of the official cooking-zone wattages on the ENERGY STAR record, labelled computed. Zones with a listed size but no listed wattage are omitted from the sum. A missing value scores at the category minimum. | 18600 W | 12600 W | 25% |
| Official cooktop low-power-mode energyOfficial ENERGY STAR cooktop low-power-mode energy in kilowatt-hours per year. Lower is better. Official annual energy consumption on this dataset clusters tightly, so we score this low-power field instead and still print the official annual figure on each card. A missing value scores at the category minimum (the highest low-power energy in the set). | 6 kWh/year | 5 kWh/year | 20% |

| Source note | The official cooking-zone count is 7, but the record lists size or wattage for 6 zones. Official specialty zones: Power Heating Zone. On many records the extra official zone is a warming zone with no certified size or wattage. We still score the official zone count as published, and computed total wattage sums only the published official wattages. Official annual energy consumption is the ENERGY STAR certified figure. On this dataset those official annual figures cluster tightly (roughly 175–195 kWh/year), so we show them as a detail and do not use them as a primary score. | The official cooking-zone count is 5, but the record lists size or wattage for 4 zones.
