Canon 5D has a
13.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic II processor. On the other hand, Canon 1Ds MII has a
17.0MP Full frame (36 x 24 mm ) sized CMOS sensor .
Below you can see the 5D and 1Ds MII sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 5D and Canon 1Ds MII Cameras
Canon 5D and Canon 1Ds MII have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Canon 5D has 30% larger pixel area compared to Canon 1Ds MII, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Canon 5D and Canon 1Ds MII sensors have been tested by DxO and the results show that 1Ds MII has a better overall score of 74, 3 points higher compared to 5D's score of 71.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon 5D
or the
Canon 1Ds MII ,
including hyperfocal distance.
