AMD's chip supply from Taiwan Semiconductor Manufacturing Company (TSMC) may face shortages in the second half as Nvidia has already placed a large amount of orders to TSMC in March and April and may squeeze AMD's order out of the already fully-loaded capacity, according to sources from graphics players.

Since Nvidia is set to launch its new GeForce GTX 460 GPU later in July and GF106 and GF108 in August and September, respectively, the company has already pre-booked a large volume of capacity from TSMC.

Since TSMC is likely to give its major clients, Nvidia and Qualcomm, supply priority, the sources believe AMD may not be able to share much of TSMC's capacity in the second half of 2010.

Nvidia plans to launch two versions of the GeForce GTX 460 graphics card with prices ranging between US$199-229 and targeting the ATI Radeon HD 5830 [via digitimes].
