If I can remember right, the Radeon HD's have larger memory options, up to 2 GiB (that may be FireGL, not sure), a wider memory bus and more bandwidth than the Nvidia, but it benchmarks a tad slower, though the benchmarks I've seen are those dodgy DirectX ones, not OpenGL.
C. P. U. Its not a big processor... Its a series of pipes!
