A twelve-inch pizza or the smaller oven format
Winner by situation
BOV450 is rated for an 11-inch pizza.
Both advertise four slices.
Neither provides a convection air-fry system.
Neither model supplies a convection fan, so choose a different oven for that cooking method.
What matters in practice
A 12-inch pizza has about 19% more area than an 11-inch pizza.
(12² / 11² - 1) × 100 = 19.0%. This is geometric pizza area.
Neither improves the stated four-slice breakfast batch, so BOV650 is more relevant for its larger pizza and pan fit than for toast quantity.
4 - 4 = 0 slices.
The mode count provides no reason to upgrade.
8 - 8 = 0 functions, with no fan in either oven.

Meaningful differences
| What changes | Breville Compact Smart Oven | Breville Mini Smart Oven | Why it matters |
|---|---|---|---|

| Toast | 4 slices | 4 slices | The headline breakfast capacity is unchanged. |

| Supplied bakeware | 10 by 10-inch pan | Mini-format bakeware | Check a favorite pan against each exact interior. |
What you give up
Recommendation switch
Choose Breville Compact Smart Oven. BOV450 is rated for an 11-inch pizza.
What matters in practice
A 12-inch pizza cannot be assumed to fit an oven rated for 11 inches. The larger Compact solves a direct fit problem before any discussion of cooking functions.
Both are rated for four toast slices. A breakfast-only buyer gets no stated slice-count gain from the Compact.
Neither has a convection fan or dedicated air-fry setting. Buyers seeking rapid basket crisping should consider another product family.
