X5 is the more flexible home cooking system. Professional 800 is the clear answer when motor noise is the issue that decides the purchase.

Ten programs add controls that occasional smoothie makers may never use.
Main trade-off
The enclosure makes this one of the largest and most expensive machines in the group.


Maximum recipe automation against a quieter enclosed base.
The practical choice turns on noise control and programs, then on the constraints in your own setup.
Before you choose
Do not choose Professional 800 for a large smoothie recipe simply by comparing its ninety-ounce total jar volume with X5's forty-eight-ounce container. Blendtec's current WildSide+ page lists liquid-fill measurements up to thirty-six ounces. Check the recipe's working limit and the markings on the supplied jar before planning servings. The enclosure and controls may still favor Blendtec, but the headline volume does not establish more usable liquid capacity.
This distinguishes Blendtec's total vessel volume from its published maximum liquid-fill measurement. X5's forty-eight-ounce label is also a container specification, so no universal serving-count ratio is calculated.
Professional 800's enclosure has to open for jar access, which matters when the machine sits below a shelf and you frequently add ingredients or swap recipes. Check the operating space rather than only the closed body. X5 has no surrounding enclosure, so its jar and tamper use follow a different access pattern. Choose Blendtec when the enclosure is a priority and the location accommodates it.
The Blendtec product documents a lifting sound enclosure. X5 supplies an accessible jar and tamper. This supports an access check, without inventing a clearance measurement or promising that anyone nearby will remain undisturbed.
Winner by situation
A sound enclosure or noise-focused housing reduces the sharpest motor and blade noise.
A sturdy base, clear interface and durable controls make daily use feel more settled.
A tamper or powered ingredient pusher keeps dense, low-liquid blends moving toward the blade.
A narrower 32 to 48-ounce vessel keeps smaller loads close to the blades.
Maker-approved dishwasher care is useful after sticky or oily recipes.
The base recognizes or supports several maker-approved vessels and attachments.
