Joystiq heard the Xbox 360 65nm Jasper chipset may start shipping in August. The Jasper chipset will use less power, reduce the heat and make the console less noisy.
Taiwan Semiconductor Manufacturing Co. (TSMC) will build the chips, Advanced Semiconductor Engineering will test and package them, and Nanya will supply flip-chip packaging substrates (which sure do sound important). The Jasper combo will ideally use less power, simplify cooling and, most importantly, cut back on the console's jibba jabba.
Industry analysts have also pegged TSMC as the primary candidate for Valhalla chipset production (in addition to the Jasper contract, TSMC has also built 90nm chips for an older version of Xbox 360). Valhalla is rumored to be a single super-chip that combines the properties of a 65nm CPU and 65nm GPU, and is expected to be incorporated into Xbox 360 hardware in the fall of 2009.
