AMD has denied reports claiming that it will shift 45 nm microprocessor production to Taiwan Semiconductor Manufacturing Co.The move would be seen as the company reducing its foundry relationship with Chartered Semiconductor Manufacturing  (Singapore).

AMD said in a press release that it maintains strong foundry relationships with Chartered for MPU production and TSMC for GPU and chipset production. The rumours were probably started after AMD’s CEO Hector Ruiz said AMD would seek to reduce expenses, partly by outsourcing more production to foundries.

FBR stock analyst Mehdi Hosseini pointed out that TSMC was enjoying stronger-than-expected increases in its wafer production. He claimed that the expected capex increase was due in part to “winning high-end CPU” business from AMD at the 45 nm node, with production expected in the third quarter of 2008.

AMD said that Chartered will continue producing AMD x86 microprocessors, augmenting AMD fab operations in Dresden with flexible capacity. TSMC will continue producing AMD’s graphics and chipset products.
