Bonding in silicon dioxide is giant covelant - very hard to break bonds. Bonding in carbon dioxide is simple molecular (covelant) so it's hard to break the molecules but easy to break intermolecular forces. These are weak van der Waals forces which require little energy to be brokne. Once these are broken the carbon dioxide sublimes. To melt silicon dioxide you must break covelant bonds though, which are a lot stronger and so much more energy is needed.

Silicon dioxide is a solid, carbon dioxide is a gas.
