The ATI Radeon 5XXX Thread

[Calmatory]

I thought so, too, until I counted them. Turned out GDDR5 has 62 I/O pins per chip while GDDR3/4 has 69. GDDR5's has more pins total but that's just because it has 100 power/ground pins, while GDDR3/4 has 70.

So in the end, GDDR5 indeed uses more pins no?

Edit: Ah, obviously the power/ground pins don't go trough the GPU. Nevermind.
