It's not just the name, it's the name in the niche. If A (Dell/IBM) is a generic job, a small piece in a long, long, generic chain, and B (lesser known but global) is much better known in your area of interest, then B's name counts a lot more. If A (Dell/IBM) is a global name, but you'll be in a small team, for example, designing chip architecture, and B is a bunch of rambling idiots that got lucky and now believe they will take over the world, then choose A. Make the choice based on your department, role, and manager (the more senior the better is often, though not always, true), not overall company name.
