Steve's right. There really isn't "gauranteed bandwidth" anywhere. The Internet "backbone" is just a bunch of shared switches: NAPs (Network Access Points) or MAEs (Metropolitan Access Exchanges?). At every connection after that, each smaller ISP or company or individual buys from the ISP "upstream"* Pretty much all of these downstream services are bundled together by their upstream provider, agregating bandwidth, so that a 45 Mbps upstream might service twenty to fifty or more 10 mbps downstream connections. And those 10 Mbps often provide T1 service (~1Mbps) to twenty to 100 or more downstream customers.

[*This is mostly true. Some companies, like InterNAP route around the public NAPs, but the model still works for understanding bandwidth. And it is possible to pay for preferential routing so that into a particular network you can get gauranteed bandwidth. But for the most part...]
[Egads! Does insomnia have no cure?!?]
Because most internet traffic is "bursty", this works. Net traffic is uncoordinated and predictably inconsistent. So when you add it all up, most users get most of their bandwidth most of the time, even though at no point can any amount of throughput be guaranteed (because there is no "there" to which to gaurantee such throughput). This is different than dedicated WAN connections such as Frame Relay or ATM networks. These can in fact gaurantee bandwidth. And as a result, they are notoriously inefficient, which is why IP is the world standard for large networks.
As for DSL vs. Cable Modems, it's a matter of _where_ the agregation happens. With Cable Modems, everyone in your neighborhood is physically on the same link. You immediately share bandwidth as soon as the line leaves your home. DSL has a dedicated link to the phone company, but no real gaurantee of how many DSL lines the phone company might combine to share the upstream bandwidth. A cable company could connect 45 Mbps upstream spread across 50 households (unlikely)--while a DSL provider agregates 1,000 households to the same 45 Mbps.
Therefore, the only certain difference is that cable companies have a harder time upgrading bandwidth because they have to go out to the physical infrastructure, where DSL providers can just buy more upstream connectivity and bigger switches. You can ask about ratios for agregation upstream, but I'd be surprised if they'll tell you.
A long answer to a short question.
