We recently replaced a machine that had died, and I moved the old, fairly low end Radeon card (HD 2400 XT) from the old machine to the new one, which we bought without any dedicated graphics as a cost-saving measure. The new machine does have a CPU with an Intel HD 2500 on-chip GPU (the processor in question is an i5-3470).
My understanding is that Intel HD GPUs, while better than other integrated GPUs, are still far short of dedicated GPUs in performance, especially for 3D. On the other hand, our Radeon is four years old as was low-end when we got it, so by Moore's law transistor density has doubled twice in that time, so it's possible that a modern integrated GPU actually outperforms a low-end dedicated GPU of that era, and I have seen some indication that the integrated GPU in question's 2D performance may in fact actually be better than the dedicated GPU's.
Can anybody give any idea how the two compare for 3D performance?
