Nvidia has launched a new mobile workstation GPU, the Quadro FX 3600, and it appears to be based on the 8800M series. It will feature up to 512MB of 256-bit GDDR3 memory and has a memory bandwidth of 51.2GB/sec.
The TDP is 70W, which means that this chip will add quite a bit of heat to whatever notebook it goes into; and one of the first notebooks to feature this new GPU will be the Compaq 8710w mobile workstation from HP.
The Quadro FX 3600 offers twice the memory bandwith of the Quadro FX 1600 and is on par with the desktop Quadro FX 3700. It also supports a wide range of display connectivity options, such as D-sub, DVI, HDMI and LVDS, and it does, of course, add support for HDCP encrypted signalling.
