From today's review article
"NVIDIA has moved the TMDS logic into a custom, discrete ASIC that you will find toward the front of the video card. Their reasoning was to simplify package and board routing and to speed up manufacturing efficiencies. All GeForce 8800 GTX and GTS GPUs are HDCP capable."
