The catch
Breville Smart Oven Pro
Compared with BOV650, the body is 1.9 inches wider.
Side by side
BOV845 Smart Oven Pro is the choice for convection, six-slice toast and a dedicated Slow Cook function. BOV650 Compact Smart Oven makes sense if four slices and a 12-inch pizza cover your needs in a smaller body. The Pro brings more cooking options and more room, and the Compact holds on to the everyday bake, broil and toast functions.
Before you buy
Compact's four-slice rating falls two slices short of a six-slice breakfast. BOV845's six-slice capacity can cover that nominal load without a second toast batch, as long as the bread fits as intended.
Where this comes from
That is 6 / 4 = 1.5, or 50% more advertised toast capacity, and 6 - 4 = 2 additional slice positions.
The catch
Compared with BOV650, the body is 1.9 inches wider.
The catch
Neither a convection fan nor a Slow Cook function is documented.

Breville BOV845 and BOV650 go up against each other on convection, slow cooking, toast capacity and counter space. The choice is a full-size routine or a smaller oven.
BOV845 Smart Oven Pro is the choice for convection, six-slice toast and a dedicated Slow Cook function. BOV650 Compact Smart Oven makes sense if four slices and a 12-inch pizza cover your needs in a smaller body. The Pro brings more cooking options and more room, and the Compact holds on to the everyday bake, broil and toast functions.
Which one fits
The rating for BOV845 is six slices, and for Compact it is four.
In this pair, that mode is documented only for BOV845.
Width is 17 inches for BOV650 and 18.9 for BOV845. Additional installation clearances still apply.
Those core functions are provided by both. Compact gives up the fan and the larger nominal toast load.
A dedicated Air Fry model is not among the selected ovens.
In practice
Compact's four-slice rating falls two slices short of a six-slice breakfast. BOV845's six-slice capacity can cover that nominal load without a second toast batch, as long as the bread fits as intended.
That is 6 / 4 = 1.5, or 50% more advertised toast capacity, and 6 - 4 = 2 additional slice positions.
From the published width and depth, BOV650 takes up a rectangle about 12% smaller than BOV845. This is exterior body area. It is not the installed space once safety clearances are added.
17 x 15.5 = 263.5. 18.9 x 15.9 = 300.51 square inches. The difference of 37.01 is 12.3% of BOV845's footprint.
A convection fan and the long Slow Cook workflow are the additions that count. If all you do is toast, bake and broil, you may use them less often than the extra counter space they occupy.
Convection and Slow Cook up to 10 hours are on the BOV845 list. Neither convection nor Slow Cook is among the eight listed functions of BOV650.

Breville, BOV845BSSUSC
If you can do without air fry, this oven’s ten clear presets and convection make it a strong choice for baking and roasting.

Breville, BOV650XL
The familiar LCD and Element IQ controls carry over to this four-slice Breville, in a narrower eight-function body.
Spec by spec
| Spec | Breville Smart Oven Pro | Breville Compact Smart Oven | In practice |
|---|---|---|---|
| Toast capacity | 6 slices | 4 slices | Two more advertised slice positions come with the Pro. |
| Convection fan | Yes | No | Its fan lets BOV845 circulate hot air. No measured cooking-speed difference is inferred. |
| Slow Cook | Dedicated mode, up to 10 hours before Keep Warm | No dedicated mode | For documented long low-temperature cooking, the Pro is the relevant choice. |
| Body dimensions W x D x H | 18.9 x 15.9 x 10.9 inches | 17 x 15.5 x 10.25 inches | Both need additional ventilation space, although Compact reduces the exterior footprint. |
| Included pizza pan | 13-inch pan | No pizza pan in listed accessories | Baking and broiling accessories of 10 x 10-inch come with BOV650, which is rated for 12-inch pizza. |
| Dedicated Air Fry mode | No | No | The air-fryer version of the Smart Oven family is not either of these. |
Trade-offs
Change of plan
Go with Breville Smart Oven Pro. Both documented capabilities come with BOV845.
Go with Breville Compact Smart Oven. Width on BOV650 is 17 inches.
Neither model fits. That mode is not included in either oven.
Decision guide
For convection, six-slice toast and a dedicated Slow Cook function, take the BOV845 Smart Oven Pro. If four slices and a 12-inch pizza meet your needs in a smaller body, the BOV650 Compact Smart Oven is enough. Extra cooking options and room come with the Pro, while the Compact retains the everyday bake, broil and toast functions.
The BOV845 has a concrete role in six-slice breakfasts and long slow-cooked dishes. A household that mostly reheats a small meal or makes a few slices of toast may find the BOV650's core modes sufficient. A larger number of functions helps only if those functions match your cooking.
The BOV650 body is smaller, yet the ventilation and heat clearances in its instructions still apply. The calculated footprint saving only describes the appliance rectangle, and it gives no license to wedge the oven between walls or beneath an obstruction.
Smart Oven Pro is not the same thing as Smart Oven Air Fryer Pro. In this comparison the BOV845 adds a convection fan and Slow Cook but has no dedicated Air Fry mode. When air frying is the main reason to replace another appliance, neither selected model supplies that exact setup.
