Main trade-off
Breville Smart Oven Pro
The body is 1.9 inches wider than BOV650.
Head-to-head
Choose BOV845 Smart Oven Pro for convection, six-slice toast and a dedicated Slow Cook function. Choose BOV650 Compact Smart Oven when four slices and a 12-inch pizza cover your needs in a smaller body. The Pro adds cooking options and room, while the Compact keeps the everyday bake, broil and toast functions.
Before you choose
A six-slice breakfast exceeds Compact's four-slice rating by two slices. BOV845's six-slice capacity can cover that nominal load without a second toast batch, assuming the bread fits as intended.
What this is based on
6 - 4 = 2 additional slice positions. 6 / 4 = 1.5, or 50% more advertised toast capacity.
Main trade-off
The body is 1.9 inches wider than BOV650.
Main trade-off
No convection fan or Slow Cook function is documented.

Winner by situation
BOV845 is rated for six slices. Compact is rated for four.
Only BOV845 documents that mode in this pair.
BOV650 is 17 inches wide, while BOV845 is 18.9. Additional installation clearances still apply.
Both provide those core functions. Compact gives up the fan and larger nominal toast load.
Neither selected oven is a dedicated Air Fry model.
What matters in practice
A six-slice breakfast exceeds Compact's four-slice rating by two slices. BOV845's six-slice capacity can cover that nominal load without a second toast batch, assuming the bread fits as intended.
6 - 4 = 2 additional slice positions. 6 / 4 = 1.5, or 50% more advertised toast capacity.
Using the published width and depth, BOV650 occupies a rectangle about 12% smaller than BOV845. That is exterior body area, not the installed space once safety clearances are added.
18.9 x 15.9 = 300.51 square inches. 17 x 15.5 = 263.5. Difference 37.01, or 12.3% of BOV845's footprint.
The meaningful additions are a convection fan and the long Slow Cook workflow. If you only toast, bake and broil, those additions may be used less often than the extra counter space they occupy.
BOV845 lists convection and Slow Cook up to 10 hours. BOV650's eight listed functions include neither convection nor Slow Cook.

Breville, BOV845BSSUSC
Ten clear presets and convection make this a strong baking and roasting oven for shoppers who do not need air fry.

Breville, BOV650XL
This four-slice Breville keeps the familiar LCD and Element IQ controls in a narrower eight-function body.
Meaningful differences
| What changes | Breville Smart Oven Pro | Breville Compact Smart Oven | Why it matters |
|---|---|---|---|
| Toast capacity | 6 slices | 4 slices | The Pro provides two more advertised slice positions. |
| Convection fan | Yes | No | BOV845 can circulate hot air with its fan. No measured cooking-speed difference is inferred. |
| Slow Cook | Dedicated mode, up to 10 hours before Keep Warm | No dedicated mode | The Pro is the relevant choice for documented long low-temperature cooking. |
| Body dimensions W x D x H | 18.9 x 15.9 x 10.9 inches | 17 x 15.5 x 10.25 inches | Compact reduces the exterior footprint, but both need additional ventilation space. |
| Included pizza pan | 13-inch pan | No pizza pan in listed accessories | BOV650 is rated for 12-inch pizza and includes 10 x 10-inch baking and broiling accessories. |
| Dedicated Air Fry mode | No | No | Neither is the air-fryer version of the Smart Oven family. |
What you give up
Recommendation switch
Choose Breville Smart Oven Pro. BOV845 provides both documented capabilities.
Choose Breville Compact Smart Oven. BOV650 is 17 inches wide.
Choose neither. Neither oven includes that mode.
What matters in practice
Six-slice breakfasts and long slow-cooked dishes give BOV845 a concrete role. A household that mainly reheats a small meal or makes a few slices of toast may find BOV650's core modes sufficient. The larger number of functions is useful only when those functions match your cooking.
BOV650 has a smaller body, but an oven still needs the ventilation and heat clearances in its instructions. The calculated footprint saving describes the appliance rectangle. It is not permission to install it tightly between walls or underneath an obstruction.
Smart Oven Pro does not mean Smart Oven Air Fryer Pro. BOV845 adds a convection fan and Slow Cook to this comparison, without a dedicated Air Fry mode. If air frying is the main reason to replace another appliance, neither selected model supplies that exact setup.
