Ron's comment is pretty accurate (in a general sense). But, a specific camshaft can increase both HP and Torque - but the RPM at which they are available can be drastically different between any two cams (and engine) combinations.

Typically the more radical the cam profile (lift and especially duration), the higher the power band and torque curves are moved UP the RPM scale. It is not exactly that simple as there are many other factors -- like timing, advance, lobe centers, port volume, port velocity, header design, etc. . . . but you get the point.
